高阶预估-校正燃耗方法在压水堆组件计算中的应用
Application of High-order Predict-correct Burnup Method in PWR Assembly Calculation
摘要
Abstract
The coupling calculation of transport and depletion usually adopts traditional predict-correct (PC)burnup method in PWR fuel assembly.However,the method results in the calculation error because of its assumption.In order to improve the accu-racy of burnup calculation,the modified PC burnup method was studied and high-order PC burnup method which corrected the microscopic reactivity was improved.Corre-sponding code was developed to verify and analyze these burnup methods with some benchmarks.The results indicate that new methods improve the calculation accuracy under the premise of insuring calculation efficiency.关键词
