摘要: 为进一步深化核安全审评工作,国家核安全局从美国核管制委员会(NRC)引进了大型热工水力最佳估算程序TRACE程序。本文利用TRACE程序以及辅助建模工具SNAP程序,建立了秦山核电厂二期两环路压水堆热工水力模型,进行了大破口失水事故模拟计算,得出了合理的计算结果。Abstract: In order to improve nuclear power plant safety review work, NNSA imported reactor thermal hydraulic best estimate code TRACE from NRC. In this paper, the NPQJVC two-loop PWR thermal hydraulic model is setup and LBLOCA is simulated using TRACE code and engineering modeling assistant code SNAP. The results of simulation are reasonable.
