Study of advanced evaluation system based on a fuzzy AHP method for nuclear reactors

Based on current status and developing trend of nuclear power technology, an advanced evaluation system is developed to assess nuclear reactors based on the study of a set of pre-established evaluation indices, including the selection and classification of the indices, and the determination of their weighting factors in applying AHP method. In this system the fuzzy method is used to build a fuzzy evaluation model with respect to the relativity and fuzziness of NPPs' specifications. This evaluation system is computer network based, with high flexibility for modification, and it is easy to use and to display evaluation results. Some preliminary evaluation results are provided and discussed. (authors)
