The technology

Small and modular

We believe the future for nuclear, is mass manufacturing of small reactors, with extensive quality checks. Easily installed and operated on site, and with a production output of more than one reactor per day.

40 ft container sized reactor

Normally industry scales up the size of power plants in order to reduce cost, but this also increases the financial risk significantly. Financial risk is what drives the cost of nuclear. Our molten salt reactors are small and modular, allowing them to be produced at a fraction of the cost of traditional nuclear. Any desired output is then achieved by placing multiple reactors on site.

Removing the complexity for decision makers. Companies fear the responsibility of operating a nuclear plant, decommissioning, and handling nuclear waste. We take care of all of that and just deliver reliable and green energy to the customer.

Assembly line production

containerized molten salt reactors allows for mass manufacturing and assembly line production. No onsite reactor assembly is necessary, only installation. This enables us to bring low cost manufacturing to the nuclear industry.

Burning spent nuclear fuel

by kickstarting our reactors on long-lived "waste" left in spent fuel we're able to convert it to fission products, which only needs to be stored for 300 years while rapidly scaling global energy production without the need for uranium enrichment.

Thorium and molten salt

there’s already enough mining of thorium today, that we can get all the thorium we need to power all of current civilization for the next thousand years. However, its true potential as an energy source can only be realized when used as a molten salt.

Thorium the solution

Thorium is the only element that allows for a breeder reactor in thermal spectrum. This means that the power output per kg of fissile inventory can beat any other reactor.

Thorium is a metallic element from the periodic table, number 90, with a melting point of 1750 °C and a density of 11.7 kg/L.
When mining for other materials the world already mines enough thorium to power all global energy production.
Thorium is reacted with fluorine to created thorium tetrefluoride ThF4 which is then mixed with commercially available isotopically enriched lithium 7 fluoride 7LiF to form the basis salt F7LiTh used in our reactor.
Natural occurring thorium was created in extreme and rare events, such as supernova explosions or the collision of neutrons stars and then scattered across the universe. without the energy released from the decay of thorium and uranium in the earth’s core our planet could not sustain life as it does today. thus, both the earth and molten salt reactors are powered by stardust.

Engineering focused approach to reactor development

Development is driven by extensive and iterative testing of components, which has already birthed several innovations

Selected key innovations
  • Circulates molten salt continuously in a loop in which various materials/components can be inserted
  • Flexible design allows for frequent modification to tests
  • Test loops have already aided in the development, testing and verification of several reactor components
  • Commercially available for $100,000 or for lease
  • Test data from customers is shared with Copenhagen Atomics lowering the Company’s own testing needs

Test loops are crucial in the development of molten salt reactors and allow for verification of reactor parts
