Research on Safety Evaluation of Nuclear Power Plant Based on Entropy Weight Method

Shijie ZHOU


Since the 18th National Congress of the Communist Party of China, China’s nuclear security has entered a new era of safety and efficiency. At the same time, the first white paper “China’s nuclear security” emphasizes the need to deal with various nuclear security challenges and maintain nuclear security. In this paper, an index system of nuclear power plant safety assessment is constructed, which includes three first-class indexes: internal risk assessment, external risk assessment and human risk assessment of nuclear power plant. Each index is weighted and evaluated by entropy weight method, and the safety of all nuclear power plants in operation during 2013-2018 in China is researched vertically as well as Ling’ao, Yangjiang, Ningde and Fangchenggang nuclear power plant is researched horizontally.
