Power released from the fission reactions is primarily delivered as heat over a temperature drop in an heat exchanger.
Core salt flows thru this heat exchanger. A secondary salt loop takes the heat to the conversion.
The secondary loop is needed to isolate tritium leaks from getting out of the reactor room and to move pressurised vessels away from the reactor.
The MSR can easily be adapted both to the installed base of steam generators and the new, but mature Brayton turbines. Brayton conversion has the huge advantage of aircooling. The working gas is He or N2.
Grid adaption and base load
MSRs start up, shut down and follow grid demand in seconds. MSR power generation is stable and secure so MSRs can serve as baseload.
Scalability, Small Reactor
DCMSR can be dimensioned in the range 50 – 3000 MWe. For reasons of licensing and redundancy, 300MWe might be a maximum size with small consequences for cost. Individual 300MWe units can then be tandemed into larger plants.
NuH2, NuNH3 and desalination
High quality heat is useful in a range of thermochemical applications.
Hydrogen and ammonia plants could be integrated with MSRs.
MSRs could propel tankers and power trains.
Tar sand oil refinery
To convert heavy oils to commercial fuels, both H2 and energy is needed for cracking in remote places.
