摘要 BEAVRS基准题是麻省理工学院计算反应堆物理小组2013年公布的压水堆三维全堆芯高保真计算基准题。本文使用传统两步法程序系统CASMO-4E/SIMULATE-3对其进行建模与跟踪计算。结果表明:在热态零功率(HZP)工况下,径向探测器反应率最大相对误差为-18.8%,与蒙特卡罗程序MC21程序的-16.1%相当;在燃耗深度为38.7 MW·d/tHM、堆芯功率为20.3%FP时,径向探测器反应率最大相对误差为-12.9%;在堆芯第1循环内,堆芯各燃耗点处临界硼浓度与测量值误差在40ppm以内,满足工程精度要求。 BEAVRS is a three-dimensional PWR benchmark for high-fidelity numerical code system verification released by the Computational Reactor Physics Group of MIT in 2013. Modeling and load-following calculations were accomplished and analyzed by using the traditional two-step reactor physics code system CASMO-4E/SIMULATE-3.The numerical results show that in hot zero power (HZP) condition, the maximum relative error for radi which is similar to the al M reaction rate compared with onte Carlo code MC21 (-16. d/triM and 20. 3%FP, the maximum relative error is the detector value is -18.8% 1%). For the case of 38.7MW·reduced to -12. 9%. The maximum discrepancy of simulated boron concentration versus the measured results is less than 40 ppm in the 1st cycle, which meets the engineering requirements.
