| 摘 要： | 在应用中子扩散方程六角形节块法程序时，往往需要计算组件内的精细功率分布。本文简要叙述了一种利用节块法程序的结果信息，再构造六角形组件内精细功率分布的计算方法，根据此方法编制了计算机程序ＨＥＸＰＩＮ。与细网有限差分程序的结果相比较表明：ＨＥＸＰＩＮ在堆芯功率峰值处的最大计算误差小于１％。

| Abstract: | This Paper describes a Calculating method for the reconstruction of pin power distributions in hexagonal assemblies from the results of nodal calculations.Based on this method,a code HEXPIN has been encoded and tested for some hexagonal geometry reactor benchmark probloms.Numerical results show maximum errors in peak power <1%. |
