Stable Salt Reactors build on the fundamental safety and simplicity breakthrough of molten salt fuel in essentially standard nuclear fuel tubes.

  • The fuel salt is held in vented tubes. Venting is safe because in our reactors the dangerous fission products form stable compounds, not gases.
  • The tubes are bundled into fuel assemblies similar to those in a conventional PWR. These are held in the support structure which forms the reactor modules. 
  • The tank is filled with a safe molten salt coolant, which is not pressurised like gas or water coolants in today’s power reactors and not violently reactive with air and water like sodium in today’s Fast Breeder reactors. A second similar coolant salt system takes heat from the primary coolant salt to steam generators kept well away from the reactor.
  • Refuelling is simple: Fuel assemblies are simply moved sideways out of the core and replaced with fresh fuel assemblies. This results in a near on-line refuelling process.
  • The entire construction is simple, with no high pressure systems, few moving parts, and no Pressure Vessel needing specialist foundries.
  • The reactor is continuously cooled by natural air flow, giving complete security against overheating in an accident situation

The Stable Salt Reactor Family



Stable Salt Reactors are modular in construction. Their rectangular cores can be extended module by module to create reactors from 150MW to 1500MW power.

Many versions of Stable Salt Reactors are possible. The first being developed now is a "waste burner". This uses fuel produced by a new, low cost and very simple process from spent conventional reactor fuel. Reduction in the radioactive life of that spent fuel from hundreds of thousands of years to just a few hundred years will effectively clean up a large part of the hazardous residue of the first nuclear era. Second generation Stable Salt Reactors will be able to breed new nuclear fuel from depleted uranium and thorium.
