The Second NEK Periodic Safety Review Program

Within the frame of the first NPP Krsko (NEK) Periodic Safety Review (PSR), a comprehensive and documented review has been performed of the plant operational and design status. Review confirmed that the plant was as safe as originally intended and didn’t found any structures, systems, components, human activities or administrative processes that could limit the life of the plant in the foreseeable future. This review had not revealed any major safety issue. As a result, it was found that Krsko NPP could safely operate, as a minimum up to the completion of the next Periodic Safety Review. The purpose of the present paper is to discuss a developed program for the second NPP Krsko Periodic Safety Review (PSR). The program considers three major inputs which represent a referential ground for the second Krsko PSR. They are: 1. The program, experience and results from the first NPP Krsko PSR, 2. The development of national legislation and requirements relevant for the PSR, which took place in the meantime, 3. Changes in the international perception of the PSR resulting in changes in the relevant international guiding documents reflecting on PSR. The paper discuss all relevant elements of the second Periodic Safety Review that need to be agreed and confirmed by the Regulator (SNSA). It discusses the definition of objectives and scope of the review, selection of methods and assessment criteria as well as managerial and procedural / quality assurance arrangements related to PSR. Program also provides a basic guidance to the PSR team regarding methodological approaches to be used in the assessment.
