基于中子物理计算程序包SRAC与计算流体力学软件CFX,开发了稳态情况下固态燃料熔盐堆的核热耦合程序SCBAT,解决了一般稳态3D物理-3D热工耦合程序因网格类型不同难以耦合的问题,程序具有普适性。SCBAT通过SRAC和CFX之间的数据交换实现稳态核热耦合,可将SRAC计算的功率场加载到CFX的求解文件中,将CFX计算的温度场加载到SRAC的输入卡中,此外具备带控制棒临界搜索的燃耗计算功能。分模块验证了SCBAT的有效性,并用SCBAT对10 MW固态燃料熔盐堆进行了稳态核热耦合计算,验证了核热耦合方法的有效性。
Based on neutron physics calculation package SRAC and computational fluid dynamics software CFX, a nuclear thermal coupling program SCBAT for solid fuel molten salt heap under steady-state conditions was developed, which solves the problem that the general steady-state 3D physics- Different difficult to couple the problem, the program has universal. SCBAT achieves steady-state thermal-thermal coupling through data exchange between SRAC and CFX, loads SRAC calculated power fields into CFX solution files, loads CFX calculated temperature fields into SRAC input cards, Bar Critical Search fuel burn calculation function. The validity of SCBAT was verified by sub-module. The steady state thermal-nuclear coupling of 10 MW solid fuel molten salt reactor was calculated by SCBAT, which verified the effectiveness of the thermal-nuclear coupling method.
