| Summary: | 碩士 === 中原大學 === 企業管理研究所 === 96 === The first nuclear power plant in Taiwan has been operating for 30 years since 1978. Some facilities and components are worn out and requires constant maintenance. A nuclear power plant has its own life span, but it will be shut down, dismantled and decommissioned, when the time comes. According to the life span of 40 years operating time, Chinshan Nuclear Power Plant is scheduled to be shut down in 2018. Maanshan and Kuosheng Nuclear Power Plants are scheduled to be shut down separately in 2020 and 2023.Taiwan has limited land resource and limited experiences in decommissioning. Therefore, to carry out decommissioning of nuclear power plant successively and effectively as planed is our top priority. In order to achieve our plan, it is important for us to set up a realistic evaluate structure to filtering through different decommissioning approaches for making best choices possible.
The main purpose of this research is to construct an suitable level structural evaluation system for choosing best decommissioning approach for domestic nuclear power plants. The research is proceeded through interviewing experts to find out optimum ways of decommissioning as well as the key structure and criterion on this matter.
The structure face in this research provides an 360 degrees managerial views for best results of reducing risks and making the best possible choice in nuclear power plant decommission in Taiwan.
The level structural evaluation system this research constructs includes four evaluation faces-- "Safety", "Technology", "Environment" and "Cost"; and three substitutive plans-- "Immediate dismantling", "Defered dismantling" and "Entombment". The evaluation team in this research is formed by sum of 53 experts from Institute of Nuclear Energy Research and Taipower company. Their evaluation results from the interviews conducted by this research were ran by fuzzy for further evaluation to find out the most suitable decommissioning approaches for us.
The important results of this study are as follows :
1. The evaluation team think the most important evaluation face among the four is "Safety", followed by "Environment", "Technology", and "Cost". This shows the safety concern when decommissioning a nuclear power plant is essential.
2. Overall, the best decommissioning strategy would be "Immediate dismantling", followed by "Defered dismantling", then "Entombment". The reasons for "Immediate dismantling" to be the best choice are politically correct and the quickest environmental recovery for further use.
