Abstract

Life extension is investigated as a safeguard assessment for the stability on operation of the nuclear power plants (NPPs). The Cobb-Douglas function, one of production function, is modified for the nuclear safeguard in NPPs, which was developed for the life quality for the social and natural objects. Nuclear safeguard estimator function (NSEF) is developed for the application in NPPs. The cases of NPPs are compared each other in the aspect of the secure performance. The results are obtained by the standard productivity comparisons with the designed power operations. The range of secure life extension is between 1.008 and 5.353 in 2,000 MWe and the range is between 0.302 and 0.994 in 600 MWe. So, the successfulness of the power operation increases about 5 times higher than the interested power in this study, which means the safeguard assessment has performed in the life extension of the NPPs. The technology assessment (TA) is suggested for the safe operation which is an advanced method comparing conventional probabilistic safety assessment (PSA).
