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。
The BEAVRS benchmark is a benchmark benchmark for PWR 3D full core high fidelity calculations published by the 2013 MIT Reactor Physics Group. This article uses the traditional two-step procedure system CASMO-4E / SIMULATE-3 modeling and tracking calculation. The results show that under the condition of hot zero power (HZP), the maximum relative error of radial detector response is -18.8%, which is equivalent to -16.1% of the MC21 program of Monte Carlo procedure. At the fuel burn depth of 38.7 MW · d / tHM and the core power is 20.3% FP, the maximum relative error of the radial detector response rate is -12.9%. In the first cycle of the reactor, the critical boron concentration and measured value error at each fuel burn point of the core are in the range of 40ppm or less, to meet the engineering requirements.
