分析了反应堆设计中燃耗计算程序的基本功能需求,指出了相关功能在传统确定论中的实现方式并不适用于蒙卡燃耗计算程序,针对蒙卡燃耗计算程序MOI精确组合几何与复杂燃耗链的特点,为MOI程序开发了应用于燃料/可燃毒物燃耗功能的混合燃耗模式,采用更精确的体移动实现调棒临界功能,同时还开发了复杂燃耗链下的再启动功能,初步实现了蒙卡燃耗计算程序MOI在工程上的可用性。 The basic functional requirements of fuel burn calculation program in reactor design are analyzed. It is pointed out that the implementation of the related function in traditional deterministic method is not applicable to the Monte Carlo fuel burn calculation program. In view of the Monte Carlo fuel consumption calculation program MOI precise combination geometry and complexity Combining the characteristics of fuel consumption chain, a hybrid fuel consumption mode applied to fuel / flammable poison burnup function has been developed for MOI program, more precise body movement is used to realize the critical function of wand adjustment, and the restart of complex fuel consumption chain is also developed Function, preliminary realization of the Mengka fuel consumption calculation program MOI in engineering availability.
