Application of risk-based approach in switching operations preparation at Novovoronezh NPP

Abstract

The article discusses one of the problematic issues of operating nuclear power plants - revenue losses caused by staff mistakes. Existing methods and approaches to reducing the number of such incidents are analyzed. Despite the efforts made, the problem remains relevant. One of the directions for reducing the number of equipment failures is the study and use of internal and external operational experience. A description is given of a system for preventing the recurrence of negative operating experience, developed at the Novovoronezh Nuclear Power Plant, which is used in preparation for switching equipment. The system is an information base, the information in which is structured by types of equipment used at the Novovoronezh Nuclear Power Plant, allowing only the information directly related to the upcoming switches to be communicated to the operational staff. Suggestions for its further improvement, taking into account the recommendations of the International Atomic Energy Agency, are considered. A forecast is given for the dynamics of reducing the number of violations after the introduction of this system into industrial operation.​
