长寿期压水堆采用单一可燃毒物组件的设计不是最优选择。为满足长寿期压水堆中可燃毒物对反应性控制的综合需求,本文针对具有较好中子学性能的新型可燃毒物231Pa2O3展开更多 长寿期压水堆采用单一可燃毒物组件的设计不是最优选择。为满足长寿期压水堆中可燃毒物对反应性控制的综合需求,本文针对具有较好中子学性能的新型可燃毒物231Pa2O3、PACS-J、PACS-L、167Er2O3和157Gd2O3进行组合研究。结果表明,采用“快燃耗”与“慢燃耗”可燃毒物进行组合的组件可以达到更优的结果。其中对于“低富集度”下的燃料组件,可以选用231Pa2O3与PACS-J、PACS-L与167Er2O3的组合方案;对于“高富集度”下的燃料组...
