Filed: 2020-03-03
Abstract: To prevent burial disposal of a low-level waste, a transuranium element and uranium 238 as much as possible, and thereby perform mass loss of the spent nuclear fuel.SOLUTION: A conventional resting BWR is operated again. Then, a spent nuclear fuel is manufactured into a nuclear fuel assembly as an oxide. The shortage of a nuclear fission material is compressed to thereby increase an amount of the nuclear fission material. An output density is lowered to a degree of 17 kw/l, and output operation is performed around three months (summer season and winter season). Fuel exchange is stopped in spring and autumn when electricity demand is small. The safety of a reactor is a low output density (about 17 kw/l), and the fizzle by a spontaneous neutron from Pu240 or the like of the spent nuclear fuel. While increasing the safety by making a fizzle nuclear reactor comprising a nuclear fizzle spent nuclear fuel assembly and a mechanical fizzle pressure vessel/fizzle shroud, the reprocessing is simplified as much as possible and the mass loss of the accumulated spent nuclear fuel is performed.SELECTED DRAWING: Figure 6
