Abstract (en)
[origin: WO9316477A1] A light water nuclear reactor, which derives most of its energy from thorium, utilizes a seed-blanket core arrangement and a nonparasitic and mechanically simple control system. Neither the initial fuel loading nor the fuel discharged from the reactor is useable for nuclear weapons purposes. The initial fissile fuel is enriched uranium, U-235/U-238 (20:80), which is known to be nonproliferative. The discharged fissile fuel consists of (1) uranium with about ten percent U-235 content, (2) less than one percent of the amount of plutonium produced in conventional light water reactors, (3) U-233 denatured by being uniformly mixed with more than twice as much U-238 and (4) the remaining thorium. About seventy-five to eighty percent of the reactor energy is derived by fissioning in place the U-233 formed in the thorium, thus avoiding the very expensive process of extracting and fabricating the highly gamma-active U-233 into fuel elements.
