摘　　要：基于国际经典的压水堆全堆芯Hoogenboom基准模型,对超级蒙特卡罗核计算仿真软件系统SuperMC(Super Monte Carlo Simulation Program for Nuclear and Radiation Process)进行了校验。对有效增殖因数keff、功率等反应堆关键参数进行了计算与正确性校验,对并行效率进行了分析。结果显示,SuperMC的计算结果与MCNP(Monte Carlo N Particle Transport Code)吻合较好,在使用640核计算时并行效率高达98.7%,初步验证了SuperMC在全堆芯计算中的准确性及高效性。Background： A full core Hoogenboom benchmark reactor model was proposed by Hoogenboom and Martin to monitor the increase in performance of Monte Carlo calculations of a full-size power reactor core over the coming years, Purpose： The correctness and computing performance of SuperMC （Super Monte Carlo Simulation Program for Nuclear and Radiation Process） was tested. Methods： The keff and power distribution were calculated and compared with MCNP （Monte Carlo N Particle Transport Code）, and parallel efficiency was analyzed. Results： The SuperMC calculation results agreed well with those of MCNP, with the parallel efficiency reaching up to 98.7% by using 640 processors. Conclusion： Testing results validated the accuracy and efficiency of SuperMC in full reactor core calculation.
