Eliminating device for radioactive waste and its method

Creators

Description

An LMFBR type reactor is used as a target reactor, in which radioactive wastes and fuels are disposed respectively to the inner side and the outer side of the reactor and, further, moderators are added to the inside of the radioactive wastes or disposed between the radioactive wastes and the fuel material. Then, a γ -ray accelerator is disposed at a position of γ -ray irradiation to radioactive wastes. Radioactive wastes are eliminated by (γ, n) reactions under the γ -ray irradiation. Then, neutrons generated by the reaction are irradiated to the fuel material to maintain a high neutron flux and, at the same time, heat generated in the target reactor is converted into electric power and supplied to the electron ray accelerator. Further, the neutrons are irradiated to the radioactive waste to eliminate the radioactive wastes under (n, γ) reaction. It is possible to hybridize the radioactive wastes elimination device and the reactor and increase the amount of elimination and improve the energy efficiency. (N.H.)
