A comparison of radioactive waste from an experimental fast fission reactor and an experimental D-T fusion reactor

M. Koch, M.S. Kazimi1991年Fusion Engineering and DesignIF 1.7出版社

AbstractThe radioactive waste produced by an experiment D-T fusion reactor (International Thermonuclear Experimental Reactor (ITER) has been characterized. To provide a frame of reference, it has been compared to the waste produced by an experimental advanced fast fission reactor (Experimental Breeder Reactor II (EBR-II). ITER has a sixteen times higher thermal power output than EBR-II; however, each reactor represents approximately the minimum reactor size needed to establish the feasibility of its fuel cycle. Both reactors were assumed to operate on idealized self-sufficient closed fuel cycle, i.e. the actinides and the tritium generated during operation were considered as fuel and hence extracted from the remainder of the radioactive waste and recycled back to the reactor. Under this scheme, it is found that ITER will generate radioactive waste that is somewhat more hazardous in the long term than that generated by EBR-II.

実験用D-T核融合炉(国際熱核融合実験炉、ITER)によって生成される放射性廃棄物の特性評価が行われた。比較の基準を提供するため、実験用高速核分裂炉(実験増殖炉II、EBR-II)によって生成される廃棄物と比較された。ITERの熱出力はEBR-IIの16倍であるが、各炉はそれぞれの燃料サイクルの実現可能性を確立するために必要な最小規模の炉にほぼ相当する。両炉とも、理想化された自給自足型閉鎖燃料サイクル、すなわち運転中に生成されるアクチニドとトリチウムが燃料として扱われ、放射性廃棄物の残余部分から分離されて炉にリサイクルされる方式で運転されると仮定された。この方式の下では、ITERはEBR-IIよりも長期的にはやや有害性の高い放射性廃棄物を生成することが見出された。
