| 摘 要： | 介绍了２００ＭＷ核供热堆（ＮＨＲ－２００）采用含钆可燃毒物燃料棒作为中子吸收体的设计考虑,并根据ＮＨＲ－２００燃料组件的设计参数,采用压水堆核电厂燃料元件稳态分析程序ＦＲＡＰＣＯＮ－２,并考虑到含钆芯块物性变化,对原有ＭＡＴＰＲＯ数据库中相应物性作了修改,按不同含钆量对可燃毒物棒进行稳态工况的性能分析比较。分析结果表明,ＮＨＲ－２００含钆可燃毒物棒能很好地满足堆芯设计的要求,并且有较大的安全裕度。

| Abstract: | The consideration of using gadolinia as burnable absorber in the 200MW nuclear heating reactor (NHR 200) are introduced. According to the designing parameters of NHR 200, the performance of differnet gadolinia/content fuel rods in steady condition is studied with the analysis program named FRAPCON 2, which is used in the pressurized water reactor (PWR) nuclear pwoer plants for the stable analysis on the fuel elements. Thinking of the difference of the materiality between fuel rod and gadolinia fuel rod, the necessary modification on the data base named MATPRO is conducted. It is demonstrated that NHR 200 gadolinia fuel rods can successfully fulfill the requirement of design criteria and possess high margin in safety. |
