核电厂运行产生的乏燃料在经过一定时间的贮存之后,需要转运到后处理厂进行后处理。乏燃料转运之前需要对转运过程进行安全分析和环境影响评价,而这些都需要对乏燃料的放射性源项进行计算和分析。大亚湾核电厂乏燃料源项计算任务主要包括计算乏燃料的核素成分、235U残余浓度、衰变热、放射性活度、中子源强、γ源强等参数。本年度计算量包括2个机组的共计104个乏燃料组件,本
Spent fuel generated from the operation of a nuclear power plant needs to be transported to a reprocessing plant for reprocessing after a certain period of storage. Transport of spent fuel requires a safety analysis and environmental impact assessment of the transshipment process, all of which require the calculation and analysis of radioactive sources of spent fuel. Daya Bay Nuclear Power Plant spent fuel source computing tasks include the calculation of spent fuel nuclide composition, 235U residual concentration, decay heat, radioactive activity, neutron source strength, γ source and other parameters. This year’s calculation includes a total of 104 units of 2 spent fuel assemblies, Ben
