1979年美國發生三哩島(Three Mile Island)事故;1986年烏克蘭發生車諾比(Chernobyl)事故;2011年日本福島(Fukushima)第一核電廠事故,核子事故的發生使得民眾對於核能電廠之安全性日漸關心。核能相關研究單位也對於核能電廠進行更深入的研究,因而開發出許多核能安全分析軟體。 本論文使用Fauske Associates, Inc. (FAI)所開發之嚴重事故分析程式(Modular Accident Analysis Program, MAAP)對於龍門電廠進行嚴重事故個案與輻射劑量之分析,MAAP最新版本為MAAP5。本論文分析之個案為電廠全黑事故(Station Blackout, SBO),並且對於外釋之輻射劑量進行分析。 個案研究分為兩部分,第五章為終期安全性分析報告(Final Safety Analysis Report, FSAR)之SBRC-PF-R-N個案進行分析;第六章為嚴重事故之電廠全黑事故加入緊急操作程序書之操作邏輯對電廠進行救援動作,並且延遲消防水之注入,對於消防水注水之時間進行靈敏度分析,研究延後注水對於反應爐之影響,並對於不同個案作輻射劑量之分析,探討嚴重事故與輻射劑量外釋的關連性。
After the Three Mile Island accident in the United States in1979, the Chernobyl disaster in Ukraine in 1986, and Fukushima nuclear accidents in Japan in 2011, people worried about and paid attention to the safety of the nuclear power plants. Institutes of nuclear research do more thorough researches in nuclear power plants, and develop many nuclear safety analysis softwares. This study used MAAP software which was developed by FAI to analyze Advanced Boiling Water Reactor (ABWR) at Lungmen Nuclear Power Plant. The cases being analyzed were station blackout (SBO) cases with the effects on radiation doses. There are two parts in the case studies: Chapter 5 is the study on the SBRC-PF-R-N documented in Final Safety Analysis Report (FSAR), and Chpter 6 is the study on severe accident station blackout case with Emergency Operation Procedures (EOPs). In addition, the effects of AC-Independent Water Addition (ACIWA) injections on the releases of radiation dose were also performed.
