福島事件後,全世界對核能安全更加重視,而台灣電力公司為了阻止類似的事故發生,擬定斷然處置程序指引(Ultimate Response Guideline, URG),為了能驗證斷然處置其制定的操作流程確實能有效的讓核電廠安全停機,與保障人民財產安全,本論文用PCTRAN分別模擬一百零三年核三廠演習劇本一號機(進入嚴重事故,爐心部分融毀)與二號機(未進入嚴重事故),來執行斷然處置對其成效做安全評估。
MAAP為經過認證的核電廠事故模擬軟體,本論文以相同時序,與核研所用MAAP軟體所模擬的一百零三年核三廠演習劇本結果做比對,來驗證PCTRAN其準確性的程度。PCTRAN的特色在於模擬快速、操作容易,元件的流量可以根據使用者的興趣來做調整,因此本論文模擬了蒸氣產生器的動力釋壓閥的靈敏度分析,在對PORV的開度(流量)做調整時蒸氣產生器壓力變化的速度,與水量散失的快慢。另外也模擬了RHR(餘熱移除系統)在固定注水時間時,改變注水流量,其流量隨蒸汽產生器壓力變化的誤差分析。
After the Fukushima Nuclear Disaster took place in 2011, nuclear security have been attached importance to all over the world. Therefore the Ultimate Response Guideline(URG) was developed by Taiwan Power Company for preventing Taiwan from such analogous accident of nuclear power plant as in Japan. In order to test and verify the operating procedures of URG are able to make the nuclear power reactor shut down in emergencies and ensure security of the lives and property of the citizens, PCTRAN is used to simulate the operating procedures of URG of Maanshan Nuclear Power Plant in this paper, and the result of simulation is used to analyze the effect of URG that is according to the two maneuver-play of the plant in 2014. One of the play is for number one machine, it was in serious accident, the reactor part melted down, and the other one is for number two machine, that was not in serious accident, the power recover quickly.
In the same timing of play, this study compares the result of PCTRAN with MAAP(Modular Accident Analysis Program) that is a validated software for simulating the accident of nuclear power plant and validates extent of accuracy of PCTRAN. The features of PCTRAN are fast simulating and easy operating, and the flow rate of components in the system is adjustable by user. As a result, the study analyzes the sensitivity of Power Operating Relief Valve(PORV) of Steam Generation, and the rate of the differential pressure and water loss with the aperture of PORV. Furthernore, at a fixed injection time, it also analyzes the deviation of the differential pressure of steam generation with the aperture of water flow.
