PROCESSING SYSTEM AND PROCESSING METHOD FOR SHORTENING LIFETIME OF LONG-LIFE FISSION PRODUCT BY NUCLEAR TRANSMUTATION

摘要

PROBLEM TO BE SOLVED: To provide a processing system and a processing method for shortening a lifetime of a long-life fission product by nuclear transmutation which are capable of causing nuclear transmutation by efficiently irradiating LLFP with neutrons with a simple structure.SOLUTION: A processing system for shortening a lifetime of a long-life fission product by nuclear transmutation comprises an LLFP processing apparatus 1 for irradiating LLFP with neutrons for nuclear transmutation, and a muon generation means 2 for generating muons. The LLFP processing apparatus 1 comprises: a neutron shielding container 10; a plasma confinement means 11 for confining plasma by a mirror magnetic field; a heating means 12 for heating plasma; an irradiating unit 13 for irradiating LLFP with neutrons generated by a muon catalyzed fusion reaction; a shield member 14 that shields neutrons; and a cooling means 15 that cools the shield member 14 and acts as a neutron moderator.SELECTED DRAWING: Figure 1
