I agree with you. 233U produced from Thorium can run with high neutron yield on the thermal or fast neutron spectrum and can perform very good on a fast breeder reactor.
The main reason for using Plutonium and Uranium is the spent fuel legacy from light and heavy water reactors. The second...
A tungsten hyper speed coating can also be researched.
The hyper speed W atoms literally fuse into the reactor metal alloy and may provide a flexible corrosion layer.
I do not remember which company does this coating process.
I try to access Astronuc reference with no success.
I find two references related to this topic:

Thank you Astronuc for your answer. Even when the 7Li is more expensive I see a lot of advantages over sodium.
For me the greatest advantage is that if a leak occurs on a nuclear-gas brayton turbine configuration, the compressed air can be bypassed from the heat exchanger to the...
