Aslak Stubsgaard, CTO of Copenhagen Atomics provided an update to Nextbigfuture on their development of a Molten Salt nuclear fission reactor. They are a molten salt reactor company developing a 100MW(th) thorium molten salt reactors with an initial load plutonium from spent fuel. The reactors are designed to be roughly the size of a 40-foot shipping container and can be produced on an assembly line at low cost and scalable.
The goal is a walkaway safe reactor that is mass produced in a shipping container form factor.
They have chosen to validate a paper design through regulator pre-approval stages without building anything.
In 2019, they received two major danish grants. Copenhagen Atomics partnered with Alfa Laval who are one of the world’s leading heat exchanger producers and moved a majority of their lab facilities to Alfa Laval’s site in Copenhagen.
They are building pumped molten salt reactor loops, capable of pumping 700C fluoride/chloride salt. Copenhagen Atomics will soon open up for a public investment round.
Above, you see the molten salt loops currently under construction, in Alfa Laval’s production facility.
Let Brian Wang know if you have questions in the comments here. Aslak will be contacted and answers will be placed into follow up articles.
Walk-away Safe Shipping Container Reactor
The Copenhagen Atomics waste burner version 0.2.3 is a 50 MW(t) heavy water moderated, single fluid, fluoride salt-based, thermal spectrum, molten salt reactor. Copenhagen Atomics Waste Burner 2.0 and above versions are expected to be breeder and converter type designs, breeding more fissile material than consumed while converting fissile transuranic from existing uranium cycle waste to start a thorium-based cycle. The core, fission product extraction and separation systems, dump tank, primary heat exchanger, pumps, valves, and compressors are all contained in a leak-tight 40-foot shipping container surrounded by a shielding blanket of frozen thorium salt.
Target Application
The following applications are foreseen:
– Addon units at existing nuclear sites, coupled with a spent nuclear fuel reprocessing unit.
– Ship or barge-based power systems.
– Biofuel production and desalination plants.
– Baseload power in Asia and Africa.
The reactor design effort is focussed on a small modular thorium breeder thermal spectrum fluoride molten salt reactor, made to fit inside a 40-foot shipping container and with an initial fissile inventory made up of spent nuclear fuel transuranic.
