Abstract
AbstractThe security for nuclear power plants (NPPs) is studied against nuclear material diversion to nuclear bomb. The analytic hierarchy process (AHP) method is used for the quantification. The results are the maximum comparison as the maximum pair values with weightings and the reactor number for maximum pair values. Using the life cycle of 60 years, the range of the secure operation is between 0.728695 in 9th year and 0.373538 in 15th year. This means the highest value in the range of secure power operation is about 1.95 times higher than that of the lowest value in this study. The highest and lowest values are seen as the values of Rx #1. Using this study, result quantities are found for secure operation. Once a problem is in security, nuclear safeguard assessment (NSA) is constructed using AHP method. Using this result, each country is compared and it is possible to prepare after examining the weakness in operation. It is needed to analyze a systemic international preparation and it suggests a regulation. By this study, a cooperation work with Korea and other countries is possible.KeywordsNuclear power plants (NPPs)Random numberNuclear safeguard assessment (NSA)Analytic hierarchy process (AHP)
