摘　　要：将基于三维蒙特卡罗方法的"严格两步法"(R2S)首次应用到压水堆设计分析中,初步验证了活化程序FISPACT-2007在压水堆中的应用可行性。建立了一小型压水堆三维模型,采用R2S方法对其运行40年停堆后的残余放射性活度与剂量率分布进行了计算分析。结果表明,R2S方法可用于压水堆核电厂部件活化分析与退役策略的制定。Based on 3D Monte Carlo method,the rigorous 2-step(R2S) method has been used for the design analysis of a pressurized-water reactor(PWR) for the first time.The work preliminary validated the FISPACT-2007 application feasibility in a PWR.3D model of a minitype PWR was built.Residual radioactivity and shutdown dose rates were performed after the PWR operating 40 years using the R2S method.The results indicated that the R2S method can be used in the parts activation analysis and decommissioning strategy establishment of the PWR nuclear power plant.
