Waste Transmutation and Nuclear Energy Generation Using a Tokamak Fusion-Fission Hybrid Reactor

A tokamak fusion-fission hybrid reactor is proposed as one of candidates for disposal of the long-lived actinides and fission product wastes and supply of future energy. To assess the feasibility of transmutation of long-lived radiowastes using fusion-fission hybrid reactors, a fusion core design is presented and several possible conceptual blankets are studied, for, respectively, actinides transmutation and fission product transmutation. The results show that actinides and fission products may be effectively transmuted using the presented hybrid reactors.

聚变－裂变混合堆安全性初探

对聚变－裂变混合堆的安全性进行了初步分析和探讨．主要利用改进后的混合堆放射性程序ＦＤＫＲ对混合堆产生的核废物及放射性进行计算，并将结果与压水堆、高温气冷堆和液态金属冷却快中子增殖堆进行了比较。结果表明，混合堆与裂变动力堆相比有较好的安全性。
