摘要
COSINE软件包堆芯物理分析程序(cosCORE)是一款基于节块展开法的堆芯扩散程序。为了验证cosCORE对轻水堆模型的临界计算能力与组件功率计算能力,对三维两群压水堆问题IAEA_3D基准题与BSS-14基准题进行测试验证,并与基准值进行比对。结果显示,对于IAEA_3D基准题,cosCORE与基准值keff的相对误差为0.669‰,组件相对功率误差均小于2.178%;对于BSS-14基准题,计算值与基准值keff的相对误差为0.677‰,组件相对功率最大误差为1.7331%。
Core physical analysis program(cosCORE)of COSINE software package is a core diffusion code based on the nodal method.In order to verify the ability of critical calculation and assembly-wised power distribution calculation of cosCORE for the light water reactor model,the three-dimensional two-group pressurized water reactor problem IAEA_3D benchmark and BSS-14 benchmark were tested and verified,and compared with the benchmark value.The result shows that for the IAEA_3D benchmark,the relative error of k eff between cosCORE and the reference value is 0.669‰,and the error of relative assembly-wised power distribution is less than 2.178%;For BSS-14 benchmark,the relative error of k eff between the calculated value and the reference is 0.677‰,and the maximum error of the relative power density of the components is 1.7331%.
