BEAVRS是基于20世纪60年代美国商用反应堆建立的基准题模型,具有精细的堆芯配置参数和详细的运行测量数据,是新型的反应堆分析工具验证基准题。本研究利用自主堆用蒙卡程序(RMC)对BEAVRS进行建模,计算反应堆在不同硼浓度和控制棒步数条件下的临界有效增殖系数、控制棒价值、温度系数、仪表管里的235U裂变率等一系列重要参数。结果与实测数据及同类软件结果在可接受范围,验证了RMC进行反应堆临界分析的精确性和可靠性。
BEAVRS is a new benchmarking tool for reactor analysis tools based on a benchmark model built on commercial reactors of the United States in the 1960s with fine core configuration parameters and detailed operational measurements. In this study, the BEAVRS was modeled by a monolithic autocorrelation program (RMC), and the critical effective multiplication factor, control rod value, temperature coefficient and 235U fission in the tube were calculated under different boron concentrations and control rod steps Rate and a series of important parameters. Results and measured data and similar software results are within the acceptable range, verifying the accuracy and reliability of RMC for critical reactor analysis.
