Numerical Model of Secondary Loop of Marine Nuclear Power Plant Based on RELAP5 Code

College of Nuclear Science and Technology, Harbin Engineering University, Harbin, 150001, China

摘要: 根据核动力装置二回路系统一种新的结构设计方案,结合RELAP5/MOD3.4程序,建立了二回路汽轮机、冷凝器、给水泵及预热器等主要部件的物理模型。对二回路主要部件进行了单一部件模型适应性验证分析,并探讨了系统分析程序的局部计算能力。结果表明,RELAP5/MOD3.4程序模型的稳态计算结果与设计值基本吻合,动态计算也能够满足二回路主要部件的计算精度要求。

Abstract: This paper presents a new secondary loop of nuclear power plant system,including the main com-ponents of turbine,condenser,feed pump,and heater,based on RELAP5/MOD3.4 code. The research of the single component model adaptive authentication analysis and the local computing ability of the code have been studied. The results show that the steady-state calculation results of the RELAP5/MOD3.4 code are basically consistent with the design value,and the dynamic calculations can also meet the calculation accuracy requirement of the main components in secondary loop.
