Garry Young - An excellent summary of nuclear power around the world, focused on USA and Energy, with many useful comparisons.
O. A. Potapov - Excellent documentation of Russia's experience with BN600, a sodium cooled fast reactor. Includes design, fuel, operating and, maintenance experience and isotope production.
Donald R. Riley - He evolved the SEFOR (Southwest Experimental Fast Oxide Reactor) conceptual design. SEFOR was built and successfully proved the Doppler Coefficient that shuts down a reactor using MOX fuel without any special actions. If Chernobyl had been a fast reactor it would not have destroyed itself.
