Prediction Analyses of Feedwater System Transients in Lungmen Nuclear Power Plant Startup Tests with PCTRAN
Prediction analyses of Lungmen Nuclear Power Plant (NPP) startup transient tests have been successfully conducted using a fast, efficient simulation code, Personal Computer Transient Analyzer (PCTRAN). In this paper, we have analyzed two startup transients on feedwater system and its related parametric sensitivity studies. The first one is the “loss of feedwater heating accident; the other one is “feedwater pump trip accident. Different initial operating conditions, recirculation runback rates were considered. In this study, we present our prediction results on important system parameters such as temperatures, water levels, and flow rates for these two transients. Comparisons of parameters with those from another simulation code, TRAC/RELAP Advanced Computational Engine (TRACE) and Reactor Excursion Leak Analysis Program 5 (RELAP5) of Lungmen NPP show good agreements. After different sensitivity studies, we have the confidence that PCTRAN could be a tool for training the nuclear power plant operators.
