高温气冷堆核材料衡算及其评价

Research and Evaluate on Nuclear Material Balance Method of High Temperature Gas Cooled Reactor

针对高温气冷堆(HTR)燃料元件和换料方式不同于传统压水堆的特性,HTR采用燃料元件计数与核素含量计算相结合的衡算方式,详细介绍了核素含量的计算方法,并对该算法进行系统测试和MUF不平衡差验证,证明了该衡算算法的正确性和可行性,实现了对HTR核材料平衡的监督与控制。

According to the characteristics of HTR fuel element and refueling mode,the paper uses the combination of fuel element counting and nuclide content calculation as the principle of balance.The calculation method of nuclide content is described in detail.Through system test and MUF verification, the correctness and feasibility of the balance method are proved.It is able to monitor and control the balance of HTR nuclear materials.
