核三廠二次側系統RELAP5模型建立與驗證

本論文主要內容是以電廠相關設備測試數據資料爲基礎，運用RELAP5-3D程式建立核三廠二次側蒸汽飼水系統（BOP，Balance Of Plant），並與之前所建立的核能蒸汽供應系統（NSSS，Nuclear Steam Supply System）進行系統整合。在BOP與NSSS整合完成之後，通過以核三廠RELAP5-3D分析模式對電廠的功率測試案例，與電廠所提供的不同功率（100%，75%，50%）下的熱工水力數據進行對比，對於整個核三廠模型的正確性進行驗證。最後，對於新建立的NSSS+BOP分析模型進行暫態數據校驗，通過模擬汽機跳脫和飼水泵跳脫兩個案例，並與電廠測試值進行比較分析，用以判斷新的NSSS+BOP模型建立的正確和完備性。

The main purpose of this research is to establish a RELAP5-3D BOP (Balance of Plant) system simulation model. This research depends on the integration and analysis of data according to the various components of pressurized water power plants, Maanshan Nuclear Power Plant. The RELAP5-3D thermal-hydraulic analysis software is applied to connect each functional hydraulic component that is appropriate to accomplish the simulation model. In addition, the research also includes combination of BOP and NSSS (Nuclear Steam Supply System) to build a complete simulation of a whole nuclear power plant. After combination, one power test (Thermal power is linearly changed from 100% of rated power to 75% and end at 50%) is applied on the whole model. The purpose is to verify the simulation at different power. Finally, two transients (Turbine trip and Loss of feedwater) are simulated on the model. Simulation results are compared with the plant test data at the end of this paper, which indicates that the model could simulate the Maanshan Nuclear Power Plant to a certain degree.
