摘要
主要利用ACCP程序和SCALE4.3程序包对压水堆的乏燃料元件密集贮存进行计算和分析。ACCP程序主要是用于计算获得不同富集度不同燃耗的核素成分。根据计算获得的同位素成分数据应用SCALE4.3程序包中的CASA25程序对贮存这种乏燃料的水池进行临界分析。针对岭澳3&4号机组乏燃料贮存池Ⅱ区建立计算模型。计算结果与ENSA报告符合良好,表明计算方法正确以及计算程序ACCP程序和SCALE4.3程序包可以应用于乏燃料元件密集贮存临界分析。初步建立了一套适用于燃耗信任制问题的计算软件包。
Analysis for densely storage of PWR spent fuel was accomplished by the ACCP and SCALE4.3 programs.ACCP was used to acquire the composition of nuclides with different enrichment and burnup.The criticality calculation for the spent fuel storage pool has been done by the CASA25 program.CASA25 is a module of the SCALE4.3 computer code package.The calculation model of criticality was established based on the Storage Area Ⅱ of Ling Ao Unit 3 & 4.The results of calculation are consistent with those in the ENSA report.This indicates that the calculation method is right and the program of ACCP and SCALE4.3 can be applied in analyzing critical safety of densely storage.A computer code package was established for solving the problem of burnup credible system.
