1. Nuclear Accidents Have Been Overblown:

Due to media hype surrounding three major nuclear accidents, the risk of nuclear power has been greatly overstated and therefore public opinion is against it. As a result, this very valuable tool in our arsenal against climate change is being left on the sidelines. This will be seen someday as a mistake of enormous proportions.

Let’s consider each of the accidents:

A. Chernobyl:

The Chernobyl accident occurred on April 26, 1986 when the fourth reactor suffered a huge power increase, leading to the explosion of the plant. The reactor at Chernobyl was designed and built by the Soviet Union. Two very serious safety omissions were the absence of a steel containment vessel around the reactor core and the absence of a concrete containment dome around the reactor itself. With no containment, any significant failure was bound to be catastrophic. Furthermore, the personnel that operated the reactor were inadequately trained. These are radical departures from standard design and operating procedures in other countries, therefore the Chernobyl accident should be seen as an outlier, not a representative case.

As a result of the accident, 29 disaster relief workers died of acute radiation exposure in the immediate aftermath of the accident. In 2011, The Union of Concerned Scientists estimated the worldwide additional long-term cancer deaths at 45,600, an increase of 68 millionths of one percent. The worst affected were the 25,000 residents in the most contaminated areas. They experienced an increased cancer incidence of 4%, producing an estimated additional 1,000 early deaths over time. The IAEA had predicted 4,000 deaths. After the accident, all people were evacuated from a one thousand square mile exclusion zone. With man gone, wildlife has flourished so much that the area has become a tourist attraction.

B. Three Mile Island:

On March 29, 1979, a reactor at the Three Mile Island Plant in Middleton, Pennsylvania experienced a partial meltdown. Approximately 2 million people who lived around Three Mile Island during the accident received an average radiation dose of about 1 millirem above the area’s usual background dose of 125 to 150 millirem per year. By comparison, a chest X-ray is about 6 millirem. In spite of serious damage to the reactor, the accident had negligible effects on the physical health of individuals or the environment. There were no deaths.

C. Fukushima:

On March 11, 2011, power supply and cooling to three reactors was disabled following an earthquake and tsunami, causing a partial meltdown of all three. Although 154,000 Japanese citizens were evacuated from a 12-mile exclusion zone around the power station as a precaution, radiation exposure beyond the station grounds itself was limited. There was no major public exposure, and no deaths from radiation, however Fukushima prefecture counted 1,368 deaths related to the Fukushima plant accident. The cause was mainly displacement of the sick and elderly while in temporary housing and shelters, degraded living conditions, and separation from support networks.

There are 60 nuclear power plants in the U.S. and 450 worldwide that have been operating for decades without incident. Exaggerated reporting about these accidents has caused the safety concern in the public’s mind about nuclear energy to be greatly magnified. Surprisingly, coal presents a far greater risk of exposure to radioactivity.

2. Fossil Fuels are More Dangerous than Nuclear:

A. Death Rates From Nuclear v Fossil Fuels:

The fear of nuclear power has gone viral, but it is fueled by emotion. Here are the facts:

Coal has 333 times the death rate of nuclear; oil has 249 times the death rate of nuclear, biomass has 63 times the death rate of nuclear, and gas has 38 times the death rate of nuclear.

B. Coal Plants Emit More Radiation than Nuclear Plants:

Because coal contains trace amounts of uranium and thorium, and because a typical coal-fired power plant burns 10,000 tons of coal per day, the waste produced by coal plants is actually more radioactive than that generated by their nuclear counterparts. In fact, the fly ash emitted by a power plant, a by-product from burning coal for electricity, carries into the surrounding environment 100 times more radiation than a nuclear power plant producing the same amount of energy. This is because the radioactivity from coal plants is not regulated whereas the radioactivity from nuclear plants is. This is why working at a nuclear power plant is extremely safe.

3. Disposing of Nuclear Waste:

The issue of nuclear waste storage and disposal is complex and fraught with controversy. As in the United States, nearly every nuclear waste disposal program around the world has fallen behind schedule due to scientific uncertainty and public opposition.

In 1987, the Yucca Mountain Nuclear Waste Depository was designated as the site for the disposal of U.S. nuclear waste. But the plan was vigorously opposed by the citizens of Nevada, the State of Nevada, and other non-local groups. As a result, funding for the depository ended in 2011. This was not a technological failure, but a political one. Nuclear waste continues to be stored in spent fuel pools at reactor sites where the Nuclear Regulatory Commission (NRC) has determined that spent nuclear fuel can safely be stored for at least the next 100 years.

As of 2019, the status of the proposed repository at Yucca Mountain remains uncertain. The site has been abandoned and nothing exists but a boarded up exploratory tunnel; there are no waste disposal tunnels, receiving and handling facilities, and the waste containers and transportation casks have yet to be developed. Moreover, there is no railroad to the site, and the cost to build a railroad through Nevada could exceed $3 billion. Today, the only thing that actually exists at Yucca Mountain is a single 5-mile exploratory tunnel. And there is also ongoing debate over whether the geologic features and proposed engineered barriers at Yucca Mountain will provide sufficient isolation for permanent disposal.

The Yucca Mountain repository would have a capacity of 77,000 tons. In 2003, 46,000 tons of high-level waste was stored around the country. Nuclear power facilities produce an additional 2,000 tons of waste a year. However, spent fuel and high-level radioactive waste would be shipped to Yucca Mountain on an unprecedented scale. According to a recent study completed by the National Academy of Sciences, just one year of waste shipments to Yucca Mountain would exceed all shipments made in the past 30 years. This raises a big question about the safety of transporting this material.

4. Cost of Nuclear v Solar:

If you consider only construction costs, solar is cheaper than nuclear. But nuclear plants operate at 90% capacity and solar plants only operate at most around 25%, so you would need to build four times the capacity of solar power to equal the power of nuclear.

Even with this adjustment, some calculations show that solar is still cheaper. It remains a subject of debate. But the cost of a solar plant does not take into consideration the cost of providing backup energy for solar which is legally mandated in most jurisdictions. The costs are both financial and environmental because this backup is provided by plants that run on fossil fuel. And it doesn’t count the considerable cost involved in building a vast global energy storage capacity that is currently not within the realm of our technology. The same argument applies to wind turbines, except that wind turbines are about twice as efficient as solar farms, so would need to build twice the capacity for them in order to match nuclear.

5. Lead Time to Build/Need for Federal Subsidy:

In 2013, after 30 years with no new construction of nuclear power plants, work began to expand the V.C. Summer nuclear power plant near Jenkinsville, S.C. Two new reactors were to be built at a cost of $9B. Unit 2 was to become operational in 2016 and unit 3 in 2019. By 2017 the operational dates had been pushed back to 2020, the project was only 40% complete, and cost overruns were expected to run the project cost up to $23 billion. The owners decided to abandon the project rather than saddle their customers with additional costs.

In 2013 work began to expand the Vogtle nuclear power plant near Waynesboro, Georgia. Two new reactors were to be built at a cost of $14 billion. They were scheduled to become operational in 2016. By 2018 the operational dates had been pushed back to 2021 for unit 3 and 2022 for unit 4, and cost overruns were expected to run the project cost up to $28B. Despite talk of abandoning the project, work continues.

Here’s why these projects have been plagued with problems:

• Since these are new designs with passive safety systems and a smaller footprint, they should be less expensive to build, but with new designs there is always a learning curve.
• Since no nuclear plants have been built in the U.S. in 30 years, there is little experience. For the same reason, everything from manufacturing to supply chains to regulation is ad-hoc.
• There is no existing manufacturing infrastructure and therefore no economies of scale, so the contractors must bear the high fixed costs of building the infrastructure.
• Without trained personnel, quality control and construction problems increase.
• On the regulatory side, the NRC and state authorities err on the side of caution which dramatically slows the building process.

The drawback with evaluating the success of these projects based solely on return on investment and cost to consumers is that it ignores the consequences of continuing to rely on fossil fuels. The cost of continuing to increase GHG emissions will ultimately be much higher than the cost of building these plants.

Moreover, one-third of the United States’ nuclear power fleet – 21 of 60 facilities – could be closed in the next decade before their operating licenses expire. These are mostly smaller, single reactor plants, but they provide more than one-fifth of the country’s 800 TWh (terawatt hours) of electricity from nuclear power. If they are not replaced with new nuclear plants, they will be replaced with coal and natural gas plants which would generate an estimated 275 million tons of additional CO2 annually.

What we don’t seem to be factoring into our decisions about nuclear is the consequences of not replacing fossil fuels as quickly as possible. It should not just be a matter of letting the markets decide. Nuclear is not a substitute for renewables, but it is a clean source of energy that should be included in a portfolio of GHG emission abatement efforts.

The government must step in and pay for the cost overruns on these new plants as part of an aggressive R&D budget. Once the problems normally associated with cutting edge technology and the learning curve associated with its implementation are solved, the costs will be much lower and in the range that are economically competitive.

But the Federal Government is not doing enough. The U.S. Global Change Research Program (USGCRP) is a Federal program mandated by Congress to coordinate Federal research and investments in understanding the forces shaping the global environment and their impacts on society. In 2016 (the latest I could find) it’s budget was $2.6 billion divided among 13 different agencies. By comparison, the 2018 R&D budget for the Department of Defense was $96 billion. We have the money to do this, but our priorities are terribly wrong. Another aircraft carrier or nuclear submarine is not going to be very helpful if we can’t feed ourselves.

6. Baseline Load:

To be efficient, the electric industry must match power supply with power demand. And it must provide electricity reliably. Most electricity is provided by large coal, gas, and nuclear power plants that run constantly at a maximum capacity that is designed to meet the grid’s usual demand (the baseline load). These plants are the most efficient at generating power, but it takes 8 to 10 hours for them to warm up and come on-line, and they can only operate at their peak power and cannot be adjusted to meet peak demands. In industry jargon, they are not “dispatchable” sources. To meet this demand, the industry has power plants that use gas turbines or diesel engines. They can come on-line in 10 or 15 minutes but are not very efficient.

Now consider renewable energy sources. Because their power supply is intermittent and does not match demand, we cannot count on them to supply either a base load or peak demand. This means that, until battery technology can be deployed on a global scale so that renewable energy can be stored for when it is needed, we will continue to need both large baseline power plants and peak supply power plants.

The largest battery backup plant in the world is the facility built by Tesla at the Hornsdale Power Reserve in Florida. It can store a maximum of 129 megawatt-hours of electricity – enough to supply 30,000 houses with electricity for 8 hours. This is tiny compared with the amount of renewable energy that will eventually have to be stored globally. And the plant cost $61 million, so large-scale deployment of the current technology is not feasible.

Raising the share of electricity produced by renewables above 40% creates at least two adverse effects:

• First, because baseline power produced by large power plants cannot be reduced, more and more solar farms and wind turbines must be unplugged from the system during their most productive hours because more electricity is being produced than is needed. This adversely affects both traditional power suppliers and renewable suppliers.
• Second, more back-up generating capacity is needed to fill in when wind and solar are not generating power. So there is a natural stopping point at which a marginal increment of wind or solar will become unprofitable. It has been estimated that solar and wind can only economically supply electricity to its maximum rated capacity. For wind power, this typically ranges between 20 and 40 percent, while for solar it runs between 10 and 25 percent. This means that the maximum percentage of electricity that can economically be generated by solar and wind is between 30 and 55 percent of demand.

7. Nuclear Fusion

Work continues on fusion powered plants. The advantages of fusion are high power density, low and manageable waste production, and no possibility of uncontrolled energy release. But fusion requires heating hydrogen to over 100,000,000o C at which temperature electrons are stripped from nuclei and the hydrogen becomes a plasma. This is no mean feat. And controlling the plasma is also very difficult. The behavior of plasma is chaotic. It is too hot to touch the walls of the tokamak (the containment vessel), and so it must be suspended in air by magnetic fields. Stellarators are devices that control the magnets that control the plasma by twisting its flow in specific ways. A recent new stellarator design using a fixed magnet offers a simpler approach than previous designs, and this may accelerate progress in controlling the plasma.

The largest fusion experiment in the world is ITER (the International Thermonuclear Experimental Reactor) being built by an international consortium in Provence in the south of France at a cost of $2 billion. But despite its price tag, ITER is just a proof-of-concept plant and will not provide energy for public use. And it isn’t scheduled for full power operation until 2035. Optimistically, if we get some breaks and don’t run into any insurmountable obstacles, we could see the first fusion plant online between 2050 or 2060. In the meantime, we need non-polluting baseline power now, and only fission can provide that.

Nuclear is not the sole solution, but it could be the most important element of the EDF’S portfolio of Fourth Wave Environmental Innovation to bridge us to the day when we get all our power from fusion reactors.

8. Conclusion:

We must immediately begin replacing fossil fuels with clean energy at a scale that can provide both secure baseline power and reliable peak demand power. It makes sense that we choose the only source of clean energy that can do this – nuclear.

“THORIUM 232 – From History to Reactor

This is a visual summary of all the information about thorium.
Thorium is a weak radioactive element with atomic number 90 and a half-life of 14.05 billion years. About the age of the universe. Although it is one of the rarest metals on earth, its availability is much higher and stable than that of Uranium. 99.98% of this element is encountered as thorium 232 while uranium is mostly found in as Uranium 238 which is a poor contributor for the production of energy.

Uranium reserves are estimated to be about 5.5 million tones but only 0.72% of that is U235 necessary for the reaction. In comparison, thorium reserves are estimated to be 6.3 million tones with a 99.98% usability.

The Uranium Committee  of the Energy Minerals Division of the American Association of Petroleum Geologists just released their draft 2020 Annual Report last week and the prices and supplies of U look pretty good.

The Uranium Committee monitors the global uranium industry activities, rare earth metals, and the production of electricity from nuclear power, because these drive uranium exploration and development in the United States and overseas. [Full Disclosure – I am a member of the Committee’s Advisory Group]

Modern technological societies require a lot of rare metals, such as lithium, cobalt, vanadium and neodymium, and uranium if you have nuclear power. In fact, there are 35 minerals that are critical to our society. Unfortunately, we don’t produce many of them in the United States, but are dependent on other countries like China for our supply.

This has been a recognized problem for years, but has become especially worrisome after this this pandemic has shown the flimsiness of our supply chains.

Senator Lisa Murkowski (R-AK) re-introduced her American Mineral Security Act specifically to strengthen those efforts. The bill, which was somewhat bipartisan, attempts to rebuild the domestic mineral supply chain through geological surveying, forecasting, workforce training, research and development, recycling, and a more efficient permitting process.

But uranium seems to be doing pretty well. The United States has more nuclear power plants than anyone else, and is the world’s largest producer of nuclear power, accounting for more than 30% of worldwide nuclear generation of electricity.

Our 96 reactors produce 20% of our own nation’s electricity, and requires about 25,000 tons of U each year to do so. In contrast, 624,000,000 tons of natural gas is used to generate 34% of our electricity, and 750,000,000 tons of coal for 30%. 1,000,000,000 tons of petroleum (7,200,000,000 barrels) fuels our transportation sector, the energy equivalent of 1,500,000,000 tons of coal.

But do we have enough U in North America to fuel our own nuclear future until that happens?

Fortunately for us and our northern neighbor and closest ally, the highest-grade U deposits in the world are found in the Athabasca Basin of Saskatchewan in Canada, often referred to as the “Saudi Arabia of Uranium”. And new deposits in this basin keep being discovered.

But a new U.S. uranium district has been identified in the eastern Seward Peninsula of Alaska on the eastern margins of McCarthy Basin. Thorium and rare-earth elements have been discovered in the surrounding igneous rocks, making it key to loosening China’s grip on our technological future.

Even Virginia has a huge untapped U deposit. Uranium supplies have not been a major issue since Canada and Australia have great sources and are close allies.

Uranium is leached from the original ore, either from crushed ore rock at an above-ground facility or directly underground by in situ leaching, to form U3O8 yellowcake (see figure above).

According to the United States Energy Information Administration, the USA produced a total of 170,000 lbs of U3O8 (65.4 tU) of uranium concentrate from all domestic sources in 2019, 89% less than on 2018, which itself was 33% less than in 2017. 2018 production was primarily from six facilities: five in-situ leach plants in Nebraska and Wyoming (Crow Butte Operation, Lost Creek Project, Ross CPP, North Butte, and Smith Ranch-Highland Operation) and one underground mine.

At the beginning of 2020, two conventional uranium mills – Shootaring Canyon Uranium Mill in Utah and Sweetwater Uranium Project in Wyoming – were on standby, and the White Mesa Mill in Utah was no longer producing uranium.

There’s lots and lots of U in the world, and more keeps being discovered. U resources increased about 25% over the last decade, which has kept prices low. We get most of our U from other countries, a diversity that serves us well in most thongs. But the sudden sight of our supply chains vulnerabilities in this pandemic has made some think that we should secure uranium from domestic sources.

We are also working hard to make extraction of U from seawater the real future of the U supply beyond this century, although it is a decade or two away from becoming economic. At that point, U supplies would last for billions of years, in effect, making nuclear completely renewable.

Uranium has outperformed major commodities this year, even as the energy sector has suffered from the coronavirus pandemic. MarketsInsider shows that a significant rise in uranium prices has been underway since the pandemic began, up to $34 from $24 per pound of U3O8, a price that had been pretty stable for over a year.

The uranium industry was excited last year about the Administration’s support of Section 232 of the Trade Expansion Act of 1962 that would protect the U.S. uranium mining industry. A White House task force is recommending that the federal government buy more uranium from domestic producers, mainly as a way to revive the U.S. uranium mining industry and in part as a way to address security concerns, although according to Sharon Squassoni at George Washington University those concerns are not warranted.

DOE might even create a new national uranium stockpile.

With these higher prices, many international companies are resuming extraction operations. Numerous discoveries of high-grade uranium deposits have been made in Canada and new low-grade deposits are under development in Argentina and Peru. The main Australian uranium mines in South Australia have resumed operations and mines in Western Australia are preparing to resume operations An undeveloped, new uranium “roll front” district has been identified in the eastern Seward Peninsula of Alaska with thorium and rare-earth elements.

Research funding by university and industry remains low in the United States, but state geological surveys (e.g., Wyoming and New Mexico) and the U.S. Geological Survey are moving forward with robust research on uranium and rare earths.

There is general agreement that substantial uranium (and thorium) will be available to fuel the United States as the world’s largest fleet of nuclear power. Although a few more reactors are scheduled for retirement on economic grounds and low-priced natural gas, the other reactors are operating even more efficiently, producing more power than before.

In addition, two new reactors are being completed in Georgia. Following a 30-year period during which no new reactors were built in the United States, it is expected that these two Vogtle units will come online soon after 2020.

Since mid-2007, there have been 16 license applications to build 24 new nuclear reactors, most of which are of the new small modular reactor (SMR) design.

So it seems that we have more uranium (U) than we need for hundreds of years of nuclear power as a big chunk of our energy generation. Which is critical, since we need to double nuclear power to address climate change and replace coal, even as we ramp up renewables.

Together with the fact that the nuclear industry has dealt with the pandemic better than most sectors, both uranium supply and nuclear power should not be much affected in the post-pandemic world.

Preface.   One of the most tragic aspects of peak oil is that it is very unlikely once energy descent begins that oil will be expended to clean up our nuclear mess.  Or before descent either.  Anyone who survives peak fossil fuels and after that, rising sea levels and extreme weather from climate change, will still be faced with nuclear waste as a deadly pollutant and potential weapon. 

According to Archer (2008): “… there are components of nuclear material that have a long lifetime, such as the isotopes plutonium 239 (24,000 year half-life), thorium 230 (80,000 years), and iodine 129 (15.7 million years). Ideally, these substances must be stored and isolated from reaching ground water until they decay, but the lifetimes are so immense that it is hard to believe or to prove that this can be done”.

Ro, C. 2019. The Staggering Timescales Of Nuclear Waste Disposal. Forbes.

This most potent form of nuclear waste needs to be safely stored for up to a million years. Yet existing and planned nuclear waste sites operate on much shorter timeframes: often 10,000 or 100,000 years. These are still such unimaginably vast lengths of time that regulatory authorities decide on them, in part, based on how long ice ages are expected to last.

Strategies remain worryingly short-term, on a nuclear timescale. Chernobyl’s destroyed reactor no. 4, for instance, was encased in July 2019 in a massive steel “sarcophagus” that will only last 100 years. Not only will containers like this one fall short of the timescales needed for sufficient storage, but no country has allotted enough funds to cover nuclear waste disposal. In France and the US, according to the recently published World Nuclear Waste Report, the funding allocation only covers a third of the estimated costs. And the cost estimates that do exist rarely extend beyond several decades.

Essentially, we’re hoping that things will work out once future generations develop better technologies and find more funds to manage nuclear waste. It’s one of the most striking examples of the dangers of short-term thinking.

Fred Pearce. 7 March 2012. Resilient reactors: Nuclear built to last centuries. New Scientist.

All nuclear plants have to be shut down within a few decades because they become too radioactive, making them so brittle they’re likely to crumble.

Decommissioning can take longer than the time that the plant was operational.  This is why only 17 reactors have been decommissioned, and well over a hundred are waiting to be decommissioned (110 commercial plants, 46 prototypes, 250 research reactors), yet meanwhile we keep building more of them.

Building longer lasting new types of nuclear power plants

Fast-breeders were among the first research reactors. But they have never been used for commercial power generation. There’s just one problem. Burke says the new reactors aren’t being designed with greater longevity in mind, and the intense reactions in a fast-breeder could reduce its lifetime to just a couple of decades. A critical issue is finding materials that can better withstand the stresses created by the chain reactions inside a nuclear reactor.Uranium atoms are bombarded with neutrons that they absorb. The splitting uranium atoms create energy and more neutrons to split yet more atoms, a process that eventually erodes the steel reactor vessel and plumbing.

The breakdown that leads to a reactor’s decline happens on the microscopic level when the steel alloys of the reactor vessels undergo small changes in their crystalline structures. These metals are made up of grains, single crystals in which atoms are lined up, tightly packed, in a precise order. The boundaries between the grains, where the atoms are slightly less densely packed, are the weak links in this structure. Years of neutron bombardment jar the atoms in the crystals until some lose their place, creating gaps in the structure, mostly at the grain boundaries. The steel alloys – which contain nickel, chromium and other metals – then undergo something called segregation, in which these other metals and impurities migrate to fill the gaps. These migrations accumulate until, eventually, they cause the metal to lose shape, swell, harden and become brittle. Gases can accumulate in the cracks, causing corrosion.

A reactor that does not need to be shut down after a few decades will do a lot to limit the world’s stockpile of nuclear waste. But eventually, even these will need to be decommissioned, a process that generates vast volumes of what the industry calls “intermediate-level” waste.

Despite its innocuous name, intermediate-level waste is highly radioactive and will one day have to be packaged and buried in rocks hundreds of meters underground, while its radioactivity decays over thousands of years. It is irradiated by the same mechanism that erodes the machinery in a nuclear power plant, namely neutron bombardment.

Toxic legacy

Nuclear waste is highly radioactive and remains lethal for thousands of years and is without doubt nuclear energy’s biggest nightmare. Efforts to “green” nuclear energy have focused almost exclusively on finding ways to get rid of it. The most practical option is disposal in repositories deep underground. Yet, seven decades into the nuclear age, not one country has built a final resting place for its most toxic nuclear junk. So along with the legacy waste of cold-war-era bomb making, it will accumulate in storage above ground – unless the new reactors can turn some of that waste back into fuel.

Without a comprehensive clean-up plan, the wider world is unlikely to embrace any dreams of a nuclear renaissance.

Nextbigfuture has tracked and analyzed nuclear blend, nuclear fission and other energy.

Nextbigfuture has dozens of posts comparing all energy sources based on safety utilizing the deaths per terawatt hour metric.

In 2008, Nextbigfuture had its first death per terawatt-hours for all energy sources.

Nextbigfuture has actually composed hundreds of posts about air contamination and the problems with coal, oil and natural gas. Air contamination is bad and indoor and outdoor air contamination causes 7 million deaths per year. Hardship is even worse and triggers about 18 million deaths per year. Hence getting low-cost energy from burnable dirt (coal) to lift a country out of hardship is in fact a internet gain. This particularly true if the energy can be cleaned up as quickly as possible.

The USA and UK had really unclean air from 1880 -1970 and then cleaned up their air. China has extremely filthy air from 1970 -2020 however must have relatively tidy air by 2030.

Cheap, Clean Energy Would Be Great

The World invests about $6 trillion a year buying energy and building energy. If we cleaned up the fossil fuels we would save 7 million lives per year. Nevertheless, fossil fuels are 80% of international energy use. If we can make energy half as pricey, then the world may spend $3 trillion per year instead of $6 trillion.

In 2013, Nextbigfuture kept in mind that the world should not have debates which treat money for energy research study as limited. The World invests about $100 billion per year on energy research.

Energy research and advancement (angels and endeavor capitalists) in the U.S.A. is about $10 billion per year. Worldwide it is about $50-100 billion (government and industry). For a $6 trillion per year market with an average of 2% for research, there need to be $300 billion being invested on energy research study.

The top countries in research (Japan, Israel) by percent of GDP spend 3.5 -4.2% on research study. Get energy right and the world can double the whole economy. Rather of targeting double the world energy and world economy in 2040, we might target triple or quadruple. With energy that is four times less expensive then we have a lot of energy for clean water and other methods to modification the world for the much better. We would have the energy and cash for area.

Energy is money. The energy efficiency of an economy is slow changing relationship between GDP per unit of energy utilized.

Natural gas became low expense and plentiful due to the fact that of fracking and horizontal drilling. This shows that technology can shift energy markets and the cost of energy within a few years.

We can target transforming nuclear fission energy with factory mass-produced deep burn (burn 99+% of the uranium, plutonium or thorium) with a expense of 1 cent or less per kWh. Deeper burn breeder reactors that are about three times more effective with Uranium have actually been produced.

China will quickly be mass producing deep pool nuclear fission reactors that will be walkaway safe and have costs of about 1.65 cents per kwh of thermal heat. Routine nuclear reactors for electrical power can get down to $2500 per kilowatt in China for the Hualong 1 reactors. China is down to 2.5 to 3 cents per kwh for existing nuclear fission when the interest rate for funding is 3%.

Cheap energy is great for mankind. Affordable nuclear fission with less nuclear waste is achievable. There are less technical questions than for reaching a industrial nuclear fusion breakthrough. Utilizing a baseball analogy, we should continue to go for energy tasks that get songs and doubles. Nevertheless, going for house runs with development 99% deep burn nuclear fission and for commercial nuclear combination should still be done.

Fairly predictable energy and transport projects with relatively low technical threat:
Converting all new vehicles to electric cars and trucks. Tesla has made 1 million electric cars and trucks and there are about 5 million electric automobiles on the roadways now. Electric cars can be utilized for 1 million miles of driving due to the fact that they have fewer moving parts and simpler upkeep.

Electrifying transportation can happen much faster than replacing all brand-new (100 million per year) and used cars and trucks (1.5+ billion old vehicles and trucks). We can convert the ridesharing automobiles to electric first.

Trucks use far more fuel and generate far more pollution than cars and trucks. The Tesla Semi could enable trucks to be transformed to electrical and get contaminating trucks away from cities where most individuals live.

Electrifying lorries would stop the use of about 15 -20 million barrels per day of oil.

Converting coal plants for heating in Northern China to nuclear district heating reactors might stop the burning of up to 500 million lots of coal each year.

ThorCon is working on mass production of a molten salt nuclear reactor. Molten Salt nuclear reactors were developed and operated in the 1960 s in the U.S.A. at a couple of megawatts of power.

About 15% of the World’s nuclear waste (unburned uranium) is reprocessed every year. China has prepares to scale up reprocessing to close the nuclear fission fuel cycle. This would involve structure many breeder reactors. Breeder reactors have actually been built and run. There are improved variations that have been funded and are in advancement and building and construction.

Mass production of traditional nuclear fission reactors could see 500 -1000 Gigawatts of nuclear power by about 2060 and if breeders and reprocessing centers are built the fuel cycle can be closed. The main location this will occur is in China. If China does not pick a mass nuclear fission route then the nuclear fission market will be far less unless there are energy job advancements.

If we are handling the World’s energy job portfolio, then we need to increase general energy research study to $300-600 billion each year. The molten salt fission reactors and district heating deep pool reactors need to be established. About 5 -10% of general research need to go for different nuclear blend tasks. More technologies ought to be explored since there will be the benefits from reduced air contamination damage (economic, lives and health) and from the financial cost of more pricey energy.

Correcting a Critic About My Nuclear Combination Protection

Daniel Jassby is a research physicist, who worked on nuclear combination experiments for 25 years at the Princeton Plasma Physics Lab. Daniel has composed a paper which he has actually published at Vixra called “Voodoo Fusion Energy”.

Daniel points out about 15 of my nuclear blend posts and ignores where I had important posts of nuclear fusion, summaries of combination and contextual analysis. My summaries and criticism happened many years before Daniel’s short article. Daniel himself is a enormous hypocrite. He worked on the goal of nuclear combination experiments for 25 years and did not start calling it out publicly up until 18 years after he retired.

I have noted the insults of this short article before. However, a nuclear combination scientist brought it up in a recent conversation. I wanted to address it once again.

Of the nearly 30,000 short articles that I have written on Nextbigfuture, I have composed about 700 about nuclear fusion and are tagged with blend as a category. There are nearly 2000 articles on energy.

Daniel grumbles in the 15 posts, I did not slam each project as they were being announced.

Daniel got paid for 25 years working on nuclear combination and has been retired given that 1999. Daniel might have actually written about each nuclear blend startup as they announce and slam timelines and propositions as they are made. Nevertheless, he did not. He has actually composed two posts for the Publication of the Atomic Scientist. One knocks the ITER job and another claims that even if nuclear combination energy is commercialized that it will not be that good.

So Daniel picked to get paid for 25 years working towards a goal that he now declares draws.

Nextbigfuture Has Pointed out Delays, Technical Risks and Other Problems for Years Before Daniel’s Voodoo Combination Post

Daniel disregarded the multiple Nextbigfuture combination summaries and analysis posts. He cherry-picked the 3% of the articles on announcements.

I have actually written numerous summaries on the work on nuclear blend.

In 2018, one of the vibrant sub-titles kept in mind the issues and large delays in schedules.
Most of the venture-funded possibilities for advancement nuclear combination have stalled or have sluggish progress

I note in the summaries that schedules slipped and work is proceeding more gradually than claimed. I had a summary of fusion jobs in 2010.

I have pointed out the New Combination Race slides which track triple blend item accomplished by tasks and experiments.

I had an upgrade in 2014, that noted the sluggish rate of progress and schedule slippage.

Daniel claimed I was constantly uncritical. This is incorrect. I likewise provided better summaries and analysis than Daniel has. I would also note that Daniel is a hypocrite for taking 25 years of salary from Princeton Plasma Physics Lab before choosing to be important of the objective and projects. Is Daniel going to give back part of his income to the taxpayers that partially fund Princeton?

For the last lots years, Wang has actually priced quote uncritically forecasts of future
accomplishments with dates supplied by task promoters. Wang treats all jobs
and unjustified claims seriously, however you, dear reader, will simply take note of the dates
promised for business combination reactors.

Another 2014 summary of blend jobs.

In the 2013 Nextbigfuture nuclear blend summary, I kept in mind the slippage with Tri Alpha Energy.

In 2010, I had a summary that talked about the path to commercializing nuclear blend and how we needed to work on enhancing nuclear fission.

In 2010, I kept in mind Eric Drexler’s criticism of the Tokomak and some other nuclear fusion jobs.

Eric : As numerous of you have noted, what I say about “fusion power” is actually about tokamaks, the dominant method to combination today. I’ve been following the advancement of blend power ideas, consisting of the many alternative approaches, for years now. All machines that appearance more-or-less like existing tokamaks (stellarators, for example) would have similar capital-cost problems.

Laser-driven inertial confinement schemes are various but have led to sketches of power plants that once again seem extremely implausible.

Bussard suggested a number of fusion-machine principles, including a scheme for a extremely various kind of tokamak (with a small, disposable core), and, of course, the totally different Polywell approach. There’s not much in print about Polywell, at a technical level, but from what I‘ve read, (1) I’d offer long odds against the proposition that the scheme actually makes physical, technological sense, and (2) I’m glad to see that it’s being examined more carefully.

I said in 2010. I believe ITER is inferior to deep burn fission by itself. I promoted deep burn fission and getting to faster building times and annular nuclear fuel and other enhancement to reach 1 -2 cents per kilowatt hour with very little waste.

Nextbigfuture has written posts about bad declares from ITER and nuclear fusion startups.

ITER and Many Nuclear Blend Start-ups Usage Deceptive Power Terms.

ITER fusion project is even worse than advertised

ITER blend project lies about the dates, budget plan and power levels

The hope and speculation is that after DEMO’s a nation might then continue to make a industrial combination reactor model. However the science and physics might make complex things and another pre-prototype might be needed.

So several pre-prototype tasks out to 2060. State four countries each with their own $100-200 billion job out to 2060.

Then models out to 2070. This is all presuming the innovation is working.

Fig. 1 shows the Zr 3d, O 1 s, C 1 s, and Sn 3d HRPES spectra obtained from ZIRLO before the deposition of H₂O. Previous study reveals that tin element alone was detected by X-ray photoelectron spectroscopy (XPS), among the minor alloying elements present in ZIRCALOY-4 cladding¹⁰. When we performed preliminary experiments using commercial XPS (VG Scientific ESCALAB 220i-XL), the Fe 2p and Nb 3d peaks were not observed in ZIRLO; moreover, the Nb 3d signal was not detected in our HRPES spectrum. Therefore, to enhance the surface sensitivity without considering the detection of the Fe 2p signal, we lowered the photon energy as much as possible, resulting in a photon energy of 710 eV. Furthermore, as the primary analysis in this study involves the Zr 3d spectra, we reduced the photon energy up to 400 eV to obtain the most sensitive Zr 3d HRPES profiles. Fig. 1a displays the Zr 3d spectra acquired at photon energies of 400, 630, and 710 eV, respectively. The Zr 3d profiles obtained at photon energies of 630 and 710 eV were similar; however, that obtained at 400 eV was different. The electron inelastic-mean-free-paths (IMFPs) at photon energies of 400, 630, and 710 eV for Zr 3d, and 710 eV for C 1 s and Sn 3d were calculated to be 7.1, 11.4, and 12.8 Å, and 14.2 and 8.3 Å, respectively, using the NIST electron inelastic-mean-free-path database (Version 1.2) with an algorithm developed by Tanuma, Powell, and Penn^23,24. In addition, the IMFP at photon energy of 710 eV for O 1 s was approximately estimated as 7 Å using the universal curve¹⁹. In particular, the IMFPs for Zr 3d indicates that the spectrum at a photon energy of 400 eV contains more surface information compared to the others. Therefore, only the Zr 3d spectrum measured at a photon energy of 400 eV will be considered henceforth. The detailed analysis of the Zr 3d spectra with the peak fitting results is presented in Fig. 2.

(a) Zr 3d, (b) O 1 s, (c) C 1 s, and (d) Sn 3d HRPES spectra obtained from ZIRLO before the deposition of H₂O, where PE means the photon energy (eV). Black, red, blue open circles in (a) indicate Zr 3d spectra acquired at the photon energies of 400, 630, and 710 eV, respectively, which were normalized using Zr 3d_5/2 peak of zirconium metal at 179.3 eV. The dots and the solid lines in (b) represent the experimental values and the peak fitting results, respectively.

Zr 3d HRPES spectra of ZIRLO recorded at the photon energy of 400 eV (a) before the adsorption of H₂O, after the dosing of (b) 100 L and (c) 1000 L H₂O, and after annealing at (d) 100 °C, (e) 300 °C, and (f) 500 °C subsequent to the deposition of 1000 L H₂O. The open circles correspond to the experimental values, and the solid lines are obtained by peak fitting. The experimental data in (a) is the same with the spectrum obtained at the photon energy of 400 eV in Fig. 1a.

Fig. 1b displays the O 1 s HRPES profiles, in which three peaks can be observed: O1 at 530.0 eV, O2 at 531.4 eV, and O3 at 533.0 eV. The O1, O2, and O3 peaks are assigned to the O^2-, hydroxyl OH⁻, and the chemisorbed H₂O features because the binding energies associated with them appear at 530.0–530.2 eV, 531.4 eV, and 533.4 eV, respectively, in literature^25,26,27. The C 1 s HRPES profile is depicted in Fig. 1c, where two distinct peaks can be observed at 281.5 eV and 284.6 eV. We assigned the peak at 281.5 eV to zirconium carbide produced by the reaction between zirconium metal and the adsorbed hydrocarbon; this value is similar to the reported binding energy of 281.6–282.0 eV in previous investigations^10,28. In addition, the peak at 284.6 eV was assigned to adventitious carbon composed of various hydrocarbon species based on the previously reported value (284.6 eV)²⁹. As shown in Fig. 1c, the full width at half maximum (FWHM) of adventitious carbon at 284.6 eV is broader compared to that of zirconium carbide at 281.5 eV, which may be due to the existence of various types of hydrocarbons. In the Sn 3d HRPES profile (Fig. 1d), two types of Sn 3d_5/2 peaks at 484.1 and 486.0 eV, and 3d_3/2 signals at 492.5 and 494.4 eV, respectively, appeared with binding energy separation of 8.4 eV between them. In general, the binding energy of Sn 3d_5/2 is used to analyze the Sn 3d HRPES profile. It is known that the binding energies of Sn metal and the SnO₂ features in ZIRCALOY-4 cladding occur between 483.9–484.7 eV and 486.0–487.2 eV, respectively^10,18. Therefore, we assigned the two Sn 3d_5/2 peaks at 484.1 and 486.0 eV to Sn metal and the SnO₂ compositions, respectively. Thus, by analyzing the HRPES spectra (Fig. 1) obtained from ZIRLO, we established the presence of O^2-, hydroxyl OH^–, chemisorbed H₂O, zirconium carbide, adventitious carbon, Sn metal, and the SnO₂ species.

The fact that such features appeared despite our cleaning process suggests that they may be due to the intrinsic oxygen and carbon in ZIRLO, which was also observed in prior XPS studies on ZIRCALOY-4 cladding^10,21.

Fig. 2a depicts the Zr 3d HRPES profile, shown in Fig. 1a, with the peak fitting results. Because the binding energy of Zr 3d_5/2 is typically utilized to analyze the Zr 3d HRPES profile, we explain the zirconium species using the binding energy of Zr 3d_5/2. In Fig. 2a, six peaks can be observed: Zr1 at 179.3 eV, Zr2 at 180.4 eV, Zr3 at 181.3 eV, Zr4 at 182.4 eV, Zr5 at 183.1 eV, and Zr6 at 184.2 eV. We first assigned Zr1 at 179.3 eV and Zr5 at 183.1 eV to the Zr⁰ (zirconium metal) and Zr⁴⁺ (ZrO₂) features, respectively, based on their binding energies ranging from 179.1–179.3 eV and 182.9–183.4 eV in literature^9,10,18,30. In addition, it is known that the intervals of the binding energies between the Zr⁺, Zr²⁺, Zr³⁺, Zr⁴⁺ oxidation states are approximately 1 eV^1,31,32. Considering the binding energy of the Zr⁴⁺ feature (183.1 eV) in our system, we assigned Zr2 at 180.4 eV, Zr3 at 181.3 eV, and Zr4 at 182.4 eV to the Zr⁺ (Zr₂O), Zr²⁺ (ZrO), and Zr³⁺ (Zr₂O₃) compositions, respectively, which are zirconium suboxides. Moreover, Zr6 at 184.2 eV, of which a small quantity was present, was assigned to zirconium hydroxide (Zr(OH)₄) because its reported binding energy (183.6 eV) was similar to our value^33,34. Previously, through the analysis of the C 1 s HRPES profile in Fig. 1c, we had established the existence of zirconium carbide in ZIRLO. According to literature, the binding energy of zirconium carbide in the Zr 3d spectrum is 179.2 eV^10,28, which is almost the same as that of zirconium metal (179.3 eV). Although the zirconium carbide component should be considered when the Zr 3d HRPES profile is analyzed, we could not confirm whether this peak was due to zirconium metal or zirconium carbide, in agreement with the previous report ¹⁰. Hence, we had to unavoidably ascribe the peak at 179.3 eV to zirconium metal.

It has been previously revealed that the order of the surface components in intact ZIRCALOY-4 cladding are as follows: The uppermost hydrocarbon, zirconium hydroxide, zirconium dioxide, zirconium suboxides, and zirconium bulk layers¹⁰. In addition, zirconium carbide is expected to exist in the hydrocarbon layer. As a result, based on the analysis of the Zr 3d, O 1 s, C 1 s, and Sn 3d HRPES spectra, along with the prior report, we concluded that the surface species in ZIRLO cladding could be the same as previously reported. Additionally, we propose that Sn metal and SnO₂ compositions could exist within the zirconium bulk layer, and that the chemisorbed H₂O feature could be present in the uppermost layer.

To confirm the change in the relative proportions of the zirconium features depending on the H₂O coverage and annealing temperature, we calculated the ratio of each peak area obtained from the peak fitting results because the ratio of each peak integral in the Zr 3d HRPES spectra corresponds to their relative proportion (Table 1). As the proportion of zirconium hydroxide is negligible, we consider the other populations, herein. As shown in Fig. 2 and Table 1, the relative proportion of zirconium metal is the largest, and gradually decreases in the following order Zr⁺, Zr²⁺, Zr³⁺, and Zr⁴⁺, in accordance with their relative trends reported in literature¹. After the exposure of ZIRLO to 100 L and 1000 L H₂O, the relative proportion of zirconium metal decreased whereas those of the zirconium oxides including the Zr⁺, Zr²⁺, Zr³⁺, and Zr⁴⁺ features mostly increased (Fig. 2 and Table 1). This indicates that when H₂O is adsorbed on ZIRLO, H₂O and zirconium metal in ZIRLO react each other, relatively decreasing and increasing the metal population and the total quantity of zirconium oxides, respectively, in agreement with previous research on H₂O adsorbed on pure zirconium and ZIRCALOY-2 samples¹. This phenomenon can be explained by the dissociation of H₂O into the adsorbed oxygen and molecular hydrogen gas on ZIRLO at room temperature as reported in the prior study of water molecule on Zr(0001)³⁵. We performed annealing experiments on the 1000 L H₂O system adsorbed on ZIRLO. As shown in Fig. 2d, the Zr 3d HRPES profile after annealing at 100 °C for 30 min is similar to that before annealing, indicating that any detectable change did not occur due to annealing at this temperature. However, when temperatures of 300 °C and 500 °C were applied for 30 min, the relative percentage of the Zr⁰, Zr⁺, and Zr²⁺ valence states increased, whereas those of the Zr³⁺ and Zr⁴⁺ oxidation states decreased (Fig. 2e,f). According to literature, on annealing at 200 °C or more, the oxidation states of zirconium are converted to lower oxidation states because of the decomposition of the Zr₂O₃ and ZrO₂ compositions, and the depopulation of oxygen in the surface region accompanied by oxygen diffusion into the bulk^10,20. Therefore, we concluded that the decomposition of Zr₂O₃ and ZrO₂ and the diffusion of oxygen into the bulk lead to the reduction of the oxidation states of zirconium at 300 °C.

Fig. 3 displays the coverage and temperature dependence of the O 1 s and Sn 3d HRPES profiles. As shown in Fig. 3a, after the adsorption of 100 L and 1000 L H₂O on ZIRLO, the peak related to chemisorbed H₂O notably increases. This increase is attributed to the excess H₂O molecules on ZIRLO, which could be the remaining quantity after sufficient reaction with zirconium metal. After annealing at 100 °C for 30 min, the profile of the O 1 s HRPES spectrum remined unchanged, in accordance with the analytical result of the Zr 3d HRPES spectrum at this temperature. When the sample was annealed at 300 °C and 500 °C for 30 min, the enhanced peaks returned to the state before the adsorption of H₂O on ZIRLO, indicating that the excess H₂O molecules were completely desorbed at 300 °C. In the Sn 3d HRPES profiles (Fig. 3b), the peaks related to the Sn metal and SnO₂ compositions gradually disappear due to the deposition of 100 L and 1000 L H₂O on ZIRLO. As the adsorption of H₂O on ZIRLO increases the surface thickness, these signals may be reduced because the probing depth for ZIRLO itself relatively becomes shallow. After annealing at 100 °C for 30 min, only the peak at 486.0 eV related to the SnO₂ configuration remained indistinctly in the Sn 3d HRPES spectrum. Furthermore, after annealing at 300 °C for 30 min, it completely vanished instead of recovery, despite the desorption of H₂O molecules at this temperature. Therefore, we infer that SnO₂ composition decomposed and that Sn metal migrated into zirconium bulk at 300 °C, sequentially.

(a) O 1 s and (b) Sn 3d HRPES spectra of ZIRLO measured before the deposition of H₂O, after the adsorption of 100 L and 1000 L H₂O, and after annealing at 100 °C, 300 °C, and 500 °C subsequent to the deposition of 1000 L H₂O. O 1 s HRPES spectra in (a) were normalized using O1 peak at 530.0 eV. Sn 3d HRPES spectra obtained after annealing at up to 300 °C are exhibited in. (b) The dashed lines express the positions of the binding energy of each feature.

Chernobyl

What it’s about: The inside story of the 1986 meltdown of the Chernobyl nuclear reactor in the Soviet Union highlights the dangers of a failed national response to an unexpected catastrophe and the heroism of the individuals who stepped up in time of crisis. The (relatively) accurate period drama brings alive late Soviet politics, showing how a closed, top-down system under-appreciated the magnitude of the disaster and hid it from its own people. As the Chernobyl reactor melts down, the viewer sees the melt-down of the Soviet system itself, leading to the countries’ eventual collapse just a few years later. Yet, in a moment when we need heroes, the mini-series also highlights the incredible ingenuity and bravery of the individuals and groups that responded both during the accident and in the fraught containment and cleanup efforts that followed. The parallels to the challenges and failures of the response to COVID-19 are powerful and informative.

First They Killed My Father (មុនដំបូងខ្មែរក្រហមសម្លាប់ប៉ារបស់ខ្ញុំ)

What it’s about: “First They Killed My Father” is an excellent film directed by Angelina Jolie, based on the memoir written by Loung Ung of the same name. The film was released on Netflix in 2017 and depicts the harrowing experience of five-year-old Loung living in Cambodia from the outset of the takeover by the Khmer Rouge on April 17, 1975 through to the period of Vietnam’s invasion of Cambodia in December 1978 and then takeover in January 1979. This film is incredibly important for educating audiences (including the children of Cambodian refugees who still today struggle to discuss this recent traumatic period with their families) of the atrocities and genocide committed by the Khmer Rouge, as well the realities of famine, disease, and overwork in the concentration camps. The film’s actors also give great performances, and its cinematography is beautiful and expressive.

Band of Brothers

What it’s about: This 10-hour miniseries recounts the chronicles of Easy Company, 506th Regiment of the 101st Airborne Division in the U.S. Army. The story follows them from D-Day till the end of World War II. This almost-documentary is based on powerful interviews with survivors of Easy Company, as well as soldiers’ journals and letters. In this series, we intimately share the experiences of ordinary young men who accomplished extraordinary things under unthinkable duress and gruesome fear. The series outlines beautifully extremely admirable, yet complex, characters such as Lieutenant Richard Winters and Captain Ronald Speirs. Their actions, decisions, and the values they lived by offer exceptional food for thought and a lesson in humility. It was the worst of times, with flashes of humanity at its best. Something to think about in today’s unprecedented times.

Babylon Berlin

What it’s about: “Babylon Berlin” is one of the most enjoyable, interesting, and most importantly accessible representations of interwar Germany I’ve seen in quite a long time. Combining a discussion of the legacy of World War I, a noir detective story, increasingly fractured politics, and a vivid depiction of Weimar-era Berlin’s unique and hedonistic cultural milieu, Babylon Berlin has something to offer for both Germany-nerds (read: me, who once wrote a thesis on Weimar-era literature) and casual viewers drawn to an under-explored time period. And for those who have visited Berlin, the fact that the show is filmed largely in the city adds another draw as you watch the show’s cast traverse its streets and neighborhoods.

The Farewell

What it’s about: “The Farewell” depicts a family gathering, ostensibly for a wedding in China, but actually for a final reunion before the death of the grandmother and family matriarch (who isn’t told the truth about her health situation or the reason for the gathering). The story is based on director Lulu Wang’s own experience, initially shared in a radio story on This American Life. Nominated for two Golden Globes, “The Farewell” made President Obama’s 2019 list of favorite films. Among the film’s highlights include Zhao Shu-zhen’s portrayal of the grandmother, the visual depictions of hospitals, banquet halls, and apartments in a mid-tier Chinese city, and the too-brief scene where Chinese family members who emigrated to the U.S. and those who stayed on the mainland argue about the future of the U.S. and China. For those looking for an accessible film on U.S.-China issues (that isn’t very political), “The Farewell” deserves a watch.

The Man Who Cracked the Nazi Code

What it’s about: “The Man Who Cracked the Nazi Code” is a documentary by Denis van Waerebeke. It tells the story of Alan Turing, a brilliant British mathematician, who contributed to the Allied success in World War II by ciphering Nazi Germany’s “Enigma” encryption machine. Amidst today’s global panic and fight against COVID-19, this remarkable story provides grounds for much-needed optimism and inspiration. This short documentary combines themes of humanity and chaos with scientific reason and logic. It also demonstrates how solidarity and the coming together of human minds can overcome a united threat that transcends borders. Lastly, viewers can also get a deeper understanding of the genesis of modern-day computing and artificial intelligence, whose discovery can be traced back to Turing, the father of modern computing.

What it’s about: “Casablanca” is not a love story. No one is in love. It is a geopolitical romance about America’s relationship with Europe and the evolving American foreign policy character. Every person in the movie represents a country — except Ingrid Bergman, who plays Europe to Bogart’s America. Watch it with that in mind. “To Have and Have Not” is a much, much better movie but with the same general message. I know, you’ve seen them. Watch again! These films will make your day.

Eli is played by Sacha Baron Cohen — a welcome reversal away from the comedy the actor is largely known for. The series delivers a satisfying espionage tale along with some history, as you watch Cohen establish a relationship with Colonel Amin al-Hafez, who eventually goes on to become Syria’s president. Viewers also see Eli Cohen touring the Syrian regime’s military infrastructure at the Golan Heights which Israel would go on to capture during the Six-Day War in 1967.

Miracle

What it’s about: My favorite movie, “Miracle,” chronicles the real-life story of the 1980 U.S. men’s Olympic hockey team. It’s a film that you may be familiar with, but should watch again (and again, and again…). “Miracle” taps into the American Cold War mentality and the politicization of international sports competitions by layering engaging interpersonal stories, hometown rivalries, and arguably the greatest locker room speech of all time, against a backdrop of domestic social and economic malaise and geopolitical antagonism. From a foreign policy perspective, the movie puts the importance of the “miracle on ice” into context. By rooting the film amid U.S.-Soviet tensions, splicing in segments of President Jimmy Carter’s “crisis of confidence” speech and footage of the Iran hostage crisis, and highlighting the uncertainty of Olympic boycotts, “Miracle” underscores why the American victory was such a boost to the nation then, just as this feel-good movie can be a boost to us now.

The Motorcycle Diaries

What it’s about: On a motorcycle journey up the spine of the Andes and through the heart of the Amazon, a young middle-class medical student from Rosario, Argentina, Ernesto Guevara, is exposed to the immeasurable inequality on his home continent. Throughout the journey with his friend and “co-pilot,” Alberto Granado, the pair come face to face with the exploitation of the continent’s indigenous and marginalized peoples and its natural resources at the hands of corrupt political systems and foreign capitalist endeavors. It is over this road trip that Ernesto begins to develop the identity that will lead him to become the Marxist revolutionary, “Che” Guevara. “The Motorcycle Diaries” is a visually and emotionally captivating coming-of-age film and a thought-provoking view into the politics of inequality in South America. Ideal for a quarantine, it is a film of magnificent views — of breathtaking landscapes and the vibrant and diverse mestizo cultures of South America.

Quantico

What it’s about: The drama thriller TV series “Quantico” exposes the lives of young FBI recruits training at the Quantico base in Virginia when one of them becomes a prime suspect in a terrorist attack on Grand Central Terminal. The story shifts between the present day (the quest to find the suspect) and the past (the training at the academy, during which recruits’ complex personal stories and tangled relationships are revealed). Some viewers are captivated by the fast-paced, intricate, and suspenseful plot; critics claim that the story line is out of touch with reality. No matter which camp you might fall into, the show’s character-driven narrative will put on full display the strikingly diverse set of motives driving young people to work in law enforcement, to conduct sensitive national security investigations, and to become public servants. It may even kick up enough adrenaline for you to pursue a career as a FBI agent.

The Interview

What it’s about: This movie actually produced a diplomatic crisis. At the time of its completion, back in 2014, North Korea carried out massive cyberattacks against SONY, which distributed the film, and threatened any movie theaters that might show it. The movie mocked the young North Korean strongman Kim Jong Un about three years into his rule, and also pilloried the North Korean state, including for the horrible treatment of its own people. As mediocre as it may have been artistically, it clearly struck a nerve in Pyongyang. And I sort of liked it, I have to admit, for the comedic value and for how it (not completely inaccurately) portrayed North Korean life. I may be alone in the Brookings Foreign Policy program in recommending this movie, however!

Charlie Wilson’s War

What it’s about: The 2007 movie about America’s secret war against the Soviet Union in Afghanistan gets the most important part of the war right: the central and crucial role of Pakistan, and especially its dictator, Zia ul Huq. It was really Zia’s war. The CIA provided aid to Zia, he decided who got it, and he favored the most extreme Islamists. Much of the rest of the movie is either fiction (Israel did not help the war effort) or exaggerated (Congressman Wilson was far less important than President Jimmy Carter and Ronald Reagan in determining American strategy). It’s a great movie which gets the most important history right and played an important role after 9/11 in helping Americans understand Afghanistan, now its longest war.

The World at War

What it’s about: “The World at War,” produced by Jeremy Issacs, remains the definitive documentary of World War II. Filmed in the early 1970s, the program features interviews with key political and military leaders from the war (on both the Axis and Allied sides) as well as ordinary people. I have viewed the series numerous times over the past 30 years, and have always learned some new and interesting fact each time I have watched it.

Capernaum

What it’s about: Focusing on 12-year-old Zain who’s suing his parents for giving him life, “Capernaum” uses flashbacks to provide an intimate glimpse into life for Lebanon’s most vulnerable. Though the film focuses on the difficulties children face, especially those born in poverty, and the rights society owes them, the film also highlights the refugee and migrant struggle in Lebanon. Lebanon hosts the most refugees per capita in the world, a result of the Syrian civil war, and has struggled economically, socially, and politically under the strains of this influx. “Capernaum” also sheds light on other social issues such as human trafficking, child marriage, misogyny, and official indifference, depicting how entangled they all are. The film is at times difficult to watch but its occasional dark humor and Zain’s streetwise antics help blunt the emotional toll it takes on the viewer. I’d highly recommend you give this film your time and undivided attention.

The Expanse

What it’s about: “The Expanse” is a science fiction drama that is set hundreds of years into the future when humanity has colonized space and where political tensions are high between Earth (ruled by the United Nations), the Martian Congressional Republic on Mars, and the Outer Planets Alliance (the OPA). In the midst of this galactic feud over power and resources, the viewer is taken aboard the Rocinante, whose crew — brought together by circumstance — pulls at the thread of an unprecedented and dark discovery. “The Expanse” is both a detective thriller and political spectacle that explores the themes of diplomacy, governance, technology, exploration, the human condition, and even involves a brewing pandemic. Sure to satisfy any connoisseur of foreign affairs, it is a complex drama that expertly entertains while making you ponder the world as you know it and the distant future of foreign policy.

Atomic Blonde

What it’s about: If you’ve read Constanze Stelzenmüller’s excellent essay, “German lessons,” you’ll know how pivotal the fall of the Berlin Wall was for how Germany views its place in the world. Well, “Atomic Blonde” is a different kind of Berlin Wall story. Based on a comic book, the movie follows MI-6 operative Lorraine Broughton (played by Charlize Theron) as she navigates a divided Berlin in search of a mole in the intelligence community before the wall falls. Featuring head-bopping iconic 80s tunes and kick-ass fight scenes, this spy thriller will have you ready to fight the KGB too.

Occupied

What it’s about: “Occupied” is a Norwegian show, with three seasons currently available. Set in the near future, Middle East turmoil and U.S. withdrawal from NATO triggers an energy crisis. The Green Party takes power, led by an idealistic prime minister who cuts off fossil fuel production in the hopes of developing thorium-based nuclear power as an alternative. A desperate European Union acquiesces to a Russian-led invasion and soft occupation of Norway. As viewers are sitting at home during the coronavirus pandemic, “Occupied” provides interesting food for thought about future scenarios that could confront the trans-Atlantic relationship.

The Best Years of Our Lives

What it’s about: I collaborated on this pick with my friend Murray Biggs, a semi-retired associate professor of English and theater at Yale who has lectured on “The Cinema of War” there and at West Point. Released in 1946, “The Best Years of Our Lives” remains an American classic. Winner of numerous Oscars and other awards, with black-and-white cinematography by the innovative Gregg Toland, and running at nearly three hours, the film depicts in painful detail the social difficulties of returning veterans seeking to resume a normal place in mainstream American life. Not quite a documentary, the movie nevertheless brings home the everyday experience of those trying to adjust to civilian routine after years of acutely disruptive military service abroad. It includes a brief scene in which someone asserts that the United States made a mistake in going to war. He is promptly knocked out.

The Loved One

What it’s about: On the principle of confronting one’s worst fears head-on in grim times, I emphatically recommend the undeservedly obscure “The Loved One,” an absolutely-nothing-is-sacred 1965 black-and-white satire of the American funeral industry based on books by Evelyn Waugh and Jessica Mitford, with a screenplay by Terry Southern and Christopher Isherwood. If that’s not enough to make you drop everything, consider the stars: Robert Morse, Jonathan Winters, John Gielgud, Robert Morley, Roddy McDowall, James Coburn, Rod Steiger, Milton Berle, Tab Hunter, and — wait for it — Liberace as a funeral director at the “Whispering Glades” cemetery and mortuary. But Anjanette Comer playing an embalmer named “Aimée Thanatogenos” alone is worth the price of admission. What are you waiting for?
