主回路裂变产物源项计算程序CPFP的开发

分析了压水堆核电站一回路冷却剂中裂变产物的产生和迁移途径，建立了压水堆核电站主回路裂变产物源项计算模型，并开发了具有良好人-机界面的计算程序CPFP2.0。分别采用国外同类型软件和欧洲压水堆（EPR）堆型核电站的工程数据进行了测试，测试结果表明，CPFP2.0程序对于测试算例的计算结果与国外同类软件的计算结果之间的误差在工程可接受的范围内，与EPR堆型核电站的工程数据基本一致。 

Development of Calculation Code CPFP for Fission Product in Primary Loop of Pressurized Water Reactor Nuclear Power Plant

Base on the research of the generation and migration of fission product in the primary loop, the calculation model for the fission product in the primary loop is established, and the calculation code CPFP2.0 with a good man-machine interface is developed. The code CPFP2.0 is tested by the similar codes in other countries and the engineering data from EPR nuclear power plants. The test results show that tolerance scope between CPFP2.0 and the similar codes in other countries is within the acceptable range of engineering practice for tested case, and the difference between calculation result of CPFP2.0 and the engineering data of EPR nuclear power plant is negligible.
