摘要

本論文敘述如何建立使用進步型沸水式反應器的台電核四廠TRACE熱水流安全分析模式，以及使用此模式所做的初步穩態分析研究。模式建立採用電廠設計資料為本，並參考核四廠雷傳（RETRAN）安全分析模式資料為輔，電廠熱水流系統部分以一維組件建立，整個熱水流系統包括反應器壓力槽、槽內組件、蒸氣管路，安全釋壓閥，飼水等皆加以模擬。模式中亦包括兩個控制系統，分別是飼水三元控制系統、蒸汽旁通與壓力控制系統。模式建立後進行穩態分析研究，目前所得到的模式穩態計算熱水流參數與電廠設計參數尚有相當之差異，亦即此穩態分析未臻理想，模式仍有繼續研究與改善之空間。TRACE為一發展中而未完全成熟之熱水流安全分析程式，在本研究中發現，前後不同的TRACE版本對於穩態分析之計算有不同之結果。

This thesis describes how the safety analysis TRACE model of Lungmen ABWR was built and the present results of applying this model for steady state analysis. Development of Lungmen TRACE model is mainly based on the plant design data. The existing RETRAN safety analysis model of Lungmen is taken for an important reference for the model development. The thermal hydraulic system of the plant is composed with one dimentional components, including reactor pressure vessel and parts inside the vessel, steam lines, safety relief valves, feedwater etc. Two important plant control systems, namely feedwater control system and steam bypass & pressure control system are also included in the model. A study on steady state analysis is performed after the model was built, present result shows that the calculated thermal hydraulic parameters are quite different from the plant design values, meaning there is still room for improvement and further studies of the model before it can be utilized for safety analysis. TRACE is a still under developing thermal hydraulic analysis code, it is not fully developed yet. It is found in our study toward steady state calculation that different versions of TRACE can produce significantly different results.
