钆可燃毒物栅元燃耗计算分析初步

Burnup Calculation and Analysis of Burnable Poison Gadolinium

本文简要计算并分析了钆可燃毒物热群参数、能谱随燃耗变化的特性。同时讨论了压水堆设计中使用新型可燃毒物三氧化二钆(Gd_2O_3)的理论问题。

This paper represents the analysis and calculation of thermal group parameters of gadolinium oxide as burnable poison, and characteristics of energy spectrum with change of burnup. At the same time the paper discusses the theoretical problems of this new type of burnable poison which is used in PWR design.
