摘要
KYLIN-Ⅱ软件基于改迚预估修正方法迚行临界燃耗迭代求解。本文针对压水堆纯UO_2燃料组件、含硼可燃毒物的UO_2燃耗组件和含钆可燃毒物的UO_2燃料组件,使用KYLIN-Ⅱ软件,分析了不同燃耗步长对组件无限增殖系数K_(inf)计算结果的影响。通过比较分析,对于不同类型的燃料组件,给出了适合的燃耗步长选取,使其可以获得较高的计算精度。
KYLIN-Ⅱprogram uses a projected predictor-corrector method for the critical burnup calculation.In this paper,the effect of different depletion timestep on the calculated Kinf was analyzed for PWRs with pure UO2 fuel assemble,boron UO2 fuel assemble and gad-loaded UO2 fuel assemble,using KYLIN-Ⅱprogram.By comparing with the results,the proper depletion timestep is provided for different types of fuel assembles,to have accurate solution.
