本論文之目的為使用美國愛德華國家工程實驗室所發展的RELAP5-RT分析程式，建立我國第四座核能發電廠－龍門核能發電廠完整獨立的熱水流分析輸入模式。
本研究的主要工作包括，（1）將清華大學核電廠系統動態模擬分析實驗室提供的兩個RELAP5-RT熱水流輸入模式合併，成為龍門電廠全廠的RELAP5-RT熱水流輸入模式；（2）參照工程模擬器上與電廠設計相同的控制系統，建立龍門電廠的控制系統。本文著重於再循環流量控制系統、棒資訊及控制系統和反應爐保護系統的建立及驗證。其餘兩個重要的控制系統（即飼水控制系統及蒸汽旁通與壓力控制系統）參考RETRAN建立，不在本文討論範圍。
在輸入檔建立完成，經過穩態測試，確認控制系統能將模擬的電廠帶至穩態之後，模擬分析<一台爐內泵跳脫>及<三台爐內泵跳脫>兩個龍門電廠啟動測試暫態，並與奇異公司的啟動測試分析報告（STAR）和ALPS（Advanced Lungmen Plant Simulator）模擬的結果做比較。分析比較顯示本文所建立之龍門電廠控制系統的反應及趨勢均在預期範圍，且模擬結果，如功率變化、爐心流量、蒸氣流量等，與STAR和ALPS的結果均非常相似。唯飼水控制系統和壓力控制系統控制的相關參數，有比較顯著的差距，未來研究若能建立較接近電廠原始設計的控制系統，應能使此核能電廠的輸入模式更加完善。

The purpose of this thesis is using RELAP5-RT, a thermohydraulic system analysis program developed by INEL, to built an independent thermohydraulic analysis model for the simulation of power test transients of Lungmen Nuclear Power Station of Taiwan Power Company. The plant employs the Advanced Boiling Water Reactor (ABWR) designed by General Electric. The focuses of this research are the building of the control logics of the recirculation flow control system (RFCS), reactor protection system (RPS), and rod control ＆ information system (RCIS). The control logics of the other two major control systems, feedwater control system (FWCS), and steam bypass and pressure control system (SBPC) are developed in a separated thesis work and not included in this report.
The two separate RELAP5-RT thermohydraulic systems input decks, which model the reactor coolant system and balance of the plant of Lungmen Nuclear Power Plant, are combined into an integrated input deck. These input decks are parts of the Advanced Lungmen Plant Simulator (ALPS) developed by the Nuclear Power Plant Dynamic Simulation and Analysis Lab. of National Tsing Hua University. Then, the control logics of the Lungmen Nuclear Power Station’s control system are incorporated into theintergrated deck. The control logics are also adopted from ALPS.
The input deck developed is used to simulate two power test transients of the plant, “trip of one reactor internal pump” and ”three reactor internal pumps trip”. The results are compared with the results of the GE’s STAR and the ALPS’s simulation. The comparisons show that the RELAP5-RT input deck of Lungmen Nuclear Power Station built in the present study can mimic.
