[en] In order to solve the problems in the current social stability risk evaluation of nuclear power projects, this paper proposes the application of fuzzy analytic hierarchy process (FAHP) to calculate the index weights and the application of fuzzy comprehensive evaluation method to evaluate the risk degrees of different indexes. Then it establishes the FAHP comprehensive method by combining the respective merits of the two methods, and applies it in social stability risk assessment of nuclear power projects. Finally, a practical case is given to prove that the method has good practicability. (authors)
