Chinshan nuclear power plant (NPP) is the first plant in Taiwan and is a BWR/4 plant. People have more concern for the NPPs safety in Taiwan after Fukushima NPP disaster happened. Hence, we established the analysis methodology and performed the safety analysis of Chinshan NPP SFP (spent fuel pool) by using TRACE, MELCOR, CFD, and FRAPTRAN codes. There were two steps in this study. The first step was the establishment of Chinshan NPP SFP models by using TRACE, MELCOR, and CFD. Then, under the SFP cooling system failure condition (Fukushima-like accident), the transient analysis was performed. Additionally, the sensitive study of the time point for water spray was also performed. The next step was the analysis of the fuel rod performance by using FRAPTRAN and TRACE analysis results. Finally, the animation model of Chinshan NPP SFP was presented by using the SNAP animation function with MELCOR's results.
