Modular molten-salt reactors.
- Thermal spectrum
- Graphite moderated
- Molten fluoride salt
- Low-enriched U235 fuel. Could use Thorium.
They call their reactor design IMSR. Not clear what the ‘I’ stands for, the MSR is clearly Molten Salt Reactor.
The reactor is designed to be modular and replaceable after its 7-year life.
