No single person can design a specificities reactor type. You need detailed knowledge over reactor physics, mechanical structors, longterm behavior of materials in contact with molten salts etc. I have added an article by admiral Rickover under whose supervision the US navy nuclear reactors were build . I think several hundreds of them.

I do not understand the emphasis on thorium reactors. The status n the sixties was that for thorium U-233 reactors to breed you need thermal neutron energies that are not available in molten salts reactors. Molten salt reactors need U-235 that can not be enriched to 95 % due to agreements on non-nuclear proliferation. the U-238 associated with the U-235 will produce plutonium with all the issues involved with isotopes with a long decay period.

Thank you

Mushtaq for your reface. Indeed a very good overview

Many thanks for the various replies. Admiral Rickover’s essay seemed to me to reflect some confusion. He seems somewhat scornful of “academic” studies "The academic-reactor designer is a dilettante" But theoretical studies are needed to provide basis for design. You cannot make a reactor on the basis of trial and error. He defines the characteristics for an “academic” reactor as being:

• It is simple.
• It is small.
• It is Cheap.
• It is light.
• It can be built very quickly.
• It is very flexible in purpose ("omnibus reactor").(
• Little development is required. It will use mostly “off-the-shelf” components.

Exactly what a thorium MSR could achieve.
