This thesis uses DEA to compare the WANO's performance indicators among three nuclear power plants in Taiwan. We take the past 7 years'(1997-2003) data of 3 plants, there are 21 DMUs totally. Due to the importance of the nuclear power plant safety performance , we adopt the output estimation by assuming the input as a constant; Five outputs parameters such as unit capability factor, unplaned automatic scrams are chosen to proceed the comparison and get the relative efficiency. We also collect the WANO performance indicators data of the same type nuclear power plants as Taiwan in the United State during 1999-2003 to proceed the same comparison with the domestic three nuclear power plants , in order to understand the relative efficiency between two groups.

本文系利用数据包络分析法，针对台湾地区三座核能电厂之世界核能协会绩效指标的实绩进行实证比较，研究对象是以这三座电厂过去七年（1997--2003）来的实绩比较，每一年度为一个评估单位，共有21个DMUs，由於核能电厂安全绩效之重要性甚高，故本研究纯粹以产出项为考量的绩效评比方式，故将投入项设为常数；产出项则选取机组容量因数、非计划自动急停次数等五项参数，进行评比求出其相对效率；另外也收集了1999—2003年美国同型电厂之WANO绩效指标实绩进行比较，以了解国本国三座核能电厂相较於美国电厂之相对效率为何？
