Abstract
The invention discloses a system for transmuting nuclear wastes by utilizing an isotopic neutron source. The system comprises nuclear-waste components (1), neutron source components (2), a liquid medium (3), heat exchangers (4), a graphite reflecting layer (5), a concrete shielding layer (6) and a material exchange device (7). The system is characterized in that spontaneous neutrons of the neutron source components (2) react with the nuclear-waste components (1), heat generated in the reaction process is cooled by the liquid medium and is discharged by the heat exchangers (4); when the neutron source components (2) are completely decayed or the nuclear-waste components (1) are completely transmuted, the neutron source components (2) and the nuclear-waste components (1) are taken out of the material exchange device (7). The system disclosed by the invention has the effects that the transmuting process is completely and spontaneously carried out, human intervention can be avoided, and no new wastes are generated; and the system has the advantages of simple structure, high safety coefficient and good environment-protective performance and the like, and opens up a new path for treating the nuclear wastes.
