The Research on Burnup Characteristic of Doping Burnable Posion in PWR

Science and Technology on Reactor System Design Technology Laboratory, Nuclear Power Institute of China, Chengdu, 610041, China

摘要: 在压水反应堆(PWR)堆芯核设计中,通常采用可燃毒物来补偿反应性和展平功率分布。对于长寿期堆芯设计,可燃毒物的消耗和燃料燃耗的匹配研究更为重要。利用基于蒙特卡罗方法开发的堆芯燃耗计算程序(MOI)对天然元素、人工核素、可溶硼等多种弥散型可燃毒物进行燃耗特性分析。结果表明锕系可燃核素231Pa、240Pu等弥散型可燃毒物可用于长寿期PWR的设计。

Abstract: In PWR core design, burnable poisons are usually used for reactive compensation and power flatten. The choice of burnable poisons and how to match burnup would be the key-points for a long-life core design. We study the burnup character of doping burnable poisons（such as natural element, manual nuclide and soluble boron） in the PWR by the core burnup code MOI based on Monte Carlo method. The results show that Hf、Er and Eu doping burnable poison would be applicable for the nuclear design research on the long-life PWR core.
