To transition the United States from fossil fuels to green energy, [Democratic Governmental candidate Andrew Yang] wants the federal government to invest $50 billion in the development of thorium molten-salt nuclear reactors — and he desires them on the grid by 2027. “Nuclear isn’t a ideal service, but it’s a solid option for now,” Yang’s climate policy page checks out. It calls out thorium molten-salt reactors in specific as “a innovation we must invest in as a substitute for any shortfalls we have in our sustainable energy sources as we move to a future powered by sustainable energy.”
Thorium molten-salt reactors were first invented 60 years ago, but Yang appears to be the first presidential candidate to campaign on their pledge to make nuclear energy safer, cleaner, and more affordable. Like all molten-salt reactors, they shun solid rods of uranium-235 in favor of a liquid fuel made of thorium and a small quantity of uranium dissolved in a molten salt. This approach to nuclear energy decreases expansion risk, produces very little amounts of short-term harmful waste, and resists nuclear meltdowns. As in a conventional nuclear reactor, splitting the nuclei of a nuclear fuel—a procedure known as fission—produces heat, which gets utilized to turn a turbine to create electrical power. However the Cold War arms race meant the US was currently in the company of enhancing uranium for weapons, so nuclear reactors based on solid uranium took off while liquid reactors stalled. No country has built a commercial molten-salt reactor. As a result, numerous practical questions stay about the finest way to style a thorium liquid-fuel reactor. Foremost amongst them, says Lin-Wen Hu, director of research study and irradiation services at MIT’s Nuclear Reactor Laboratory, is finding materials that can consist of the corrosive molten salts. Moreover, figuring out how to extract undesirable aspects produced as thorium decays—such as protactinium-233 — from the fuel stays a significant technical difficulty.
