| 摘 要： | 利用界面流法计算两维六角形轻水堆燃料组件中子通量密度分布。子区内中子源在空间上采用二次分布近似，还考虑了六角形组件周边水隙对组件内中子通量密度的影响。根据提出的模型，编制了TPHEX－E程序，并对一些轻水堆六角形组件问题作了计算，计算结果与蒙特卡罗方法计算结果进行了比较，符合良好。本程序可用于六角形轻水堆燃料组件计算。

| Abstract: | This paper describes the model of calculating the flux distribution in two dimensional hexagonal geometry light water reactor fuel assembly by interface current method.The source within the meshes is assumed to be quadratic dependent on x and y coordinates.And the wa ter gap sur-rounding assembly is also considered.Based on proposal model,the code TPHEX-E is encoded and some hexagonal light water reactor assembly problems have been tested.The calculated results are compared with those of Monto Carlo method.They are all in good agreement.The code TPHEX-E can be used to the hexagonal geometry assembly calculation of LWR. |
