摘　　要：在中国聚变工程实验堆(CFETR)水冷陶瓷增殖(WCCB)包层的设计条件下,对水冷包层应用SIMP钢,使用蒙特卡罗中子输运程序MCNP与欧洲研制的材料活化计算程序FISPACT耦合计算,分析了SIMP钢结构材料的放射性比活度、衰变热、接触剂量率和辐照损伤等。通过与EUROFER-97、F82H等多种低活化钢的对比发现,SIMP钢在多个活化结果上达到国际上认可的低活化铁素体/马氏体钢(RAFM)的低活化特性。因此,SIMP钢可作为未来聚变堆包层的候选结构材料。The activation properties of SIMP steel have been simulated under the conditions of the water cooled ceramic breeder (WCCB) blanket for China Fusion Engineering Test Reactor (CFETR) by coupling of the MCNP (Monte Carlo N-Particle Transport Code) and FISPACT activation code. The simulation results of specific activity, decay heat, contact dose rate and radiation damage of SIMP steel have been fully compared with other RAFM steel such as EUROFER-97, F82H and so on. The comparisons show that the SIMP has good activation performance corresponding to low activation performance of RAFM. It is conclusion that the SIMP can be chosen as one candidate structural material used for future fusion reactor blanket.
