介绍了FMCAHR程序的燃耗计算模型及流程,并使用燃耗基准题和DRAGON程序对燃耗计算结果进行验证。验证结果表明,FMCAHR燃耗计算功能的准确性较高,适用于溶液堆的燃耗计算分析。

Fuel Management Code for Aqueous Homogeneous Reactors（FMCAHR） is developed based on the Monte Carlo transport method,to analyze the physics characteristics of aqueous homogeneous reactors.FMCAHR has the ability of doing resonance treatment,searching for critical rod heights,thermal hydraulic parameters calculation,radiolytic-gas bubbles＇ calculation and burn-up calculation.This paper introduces the theory model and scheme of its burn-up function,and then compares its calculation results with benchmarks and with DRAGON＇s burn-up results,which confirms its burn-up computing precision and its applicability in the burn-up calculation and analysis for aqueous solution reactors.
