    Research output: Contribution to journalArticleProfessional


    The article describes an approach to evaluate and improve the effectiveness of the maintenance strategies of technical systems in operating nuclear power plants. In the Experience Based Reliability Centred Maintenance (EBRCM) approach, the analyses of the history of occurred faults and the preventive maintenance programme are combines. In order to direct the analysis of the maintenance significant items, the components of the plant are classified based on their significance for reaching the maintenance objectives such as plant safety, plant availability and work safety in failure situations. Maintenance analysis is direct to those significant components, which exhibit a high number of failures. The other of less maintenance significance, but which exhibit high maintenance costs are also analysed to improve the cost-effectiveness of maintenance.
