摘　　要：根据其他CANDU型核电站的运行数据和RFSP程序的时间平均模型、实际堆芯模型的计算结果，分析了秦山三期CANDU机组慢化剂重水纯度对卸料燃耗和功率分布的影响。结果表明，不同的慢化剂重水纯度对反应堆功率分布状况基本无影响，但保持较高的慢化剂重水纯度可以获得较高的堆芯卸料燃耗，进而节省燃料费用。According to the operation data of other CANDU reactors and calculation results of time average model and real core model by RFSP code, the effect of moderator D2O purity on discharge burnup, power distribution is analyzed for the CANDU reactors of TQNPC. The analysis results show that moderator D2O purity has little effect on reactor power distribution, but high D2O purity may increase core discharge burnup and save fuel costs.
