Development of Deterministic Code System for GFR Depletion Calculation

为了快速准确地求解气冷快堆的燃耗问题,开发了一套确定论方法程序系统。基于通用的燃耗过程计算框架,选取了输运程序WIMS和扩散程序CITATION,编写了相关的数据转换、截面管理、燃耗插值、自动控制程序,实现了WIMS和CITATION程序的耦合,并对一个气冷快堆模型燃耗过程进行了模拟。结果表明:开发的确定论方法程序系统是可行的,具备分析气冷快堆燃耗过程中重要物理特性的功能。

In order to solve the depletion problem of Gas-Cooled Fast Reactor(GFR) quickly and accurately,a deterministic code system is developed.Based on the general compution framework of depletion process,some codes for data conversion,cross section regulation,depletion interpolation and automatic control,are programmed and used to couple the transport code WIMS and diffusion code CITATION.The simulation of the depletion process of one GFR model shows that the deterministic code system is feasible,and it is capable to analyze the neutronics characteristics during the depletion process of GFR.
