Cs的活度和燃耗值存在很好的单调对应关系,因此在高温气冷堆(HTR-PM)核电站示范工程中将利用探测器测量燃料球中137 Cs的活度,进而根据燃耗计算曲线确定其燃耗值。通过实验以及基于Geant4的蒙特卡罗全模拟,利用效率传递方法准确得到了系统刻度的修正因子。同时发展了快速自动的谱寻峰和峰面积分析程序用于双源实验和MCNP模拟的γ谱分析,结果表明,尽管有干扰峰的影响,该系统预计对137 Cs的活度测量相对不确定度依然可以控制在3.0%以内。在以上工作基础上成功研制并测试了一套全尺寸的燃耗测量系统原型。","authors":[{"authorName":"闫威华","id":"72ee3864-eb39-4594-8e5b-052ff1fa6a48","originalAuthorName":"闫威华"},{"authorName":"张立国","id":"77dbd26f-9951-48b1-b793-3e1a7aa6a5fd","originalAuthorName":"张立国"},{"authorName":"张钊","id":"19f9ce2d-1764-4f6a-897b-beb9883e707f","originalAuthorName":"张钊"},{"authorName":"肖志刚","id":"aac60816-dacf-4672-ab94-467aa0dd9574","originalAuthorName":"肖志刚"}],"doi":"10.11804/NuclPhysRev.31.03.366","fpage":"366","id":"72ba4aa6-c2c8-44b6-9293-9dcf608a7dc9","issue":"3","journal":{"abbrevTitle":"YZHWLPL","coverImgSrc":"journal/img/cover/YZHWLPL.jpg","id":"78","issnPpub":"1007-4627","publisherId":"YZHWLPL","title":"原子核物理评论
