Maintenance optimization is based on criticality classification. Fortum's proprietary ReMaint® Nuclear Criticality Classification methodology (patent pending) classifies nuclear power plant systems, structures, and components (SSCs) according to their impact on plant performance and enables selection of the most profitable maintenance strategy for each SSC. It optimizes the "big picture" of nuclear power plant maintenance by re-allocating maintenance resources from non-critical SSCs to those having the biggest impact on plant performance.
ReMaint® Nuclear Criticality Classification is delivered as a service where we together with NPP organization classify plant equipment with our classification methodology. Criticality criteria applied in classification is derived from NPP organization’s needs and priorities.
- NPP unavailability during operation decreases by identifying equipment whose failures cause production losses and by creating & implementing maintenance programs to prevent the failures (especially "Single Point of Vulnerability" equipment get optimized mitigation plans).
- Removing preventive maintenance tasks from “run-to-failure” class equipment can shorten outages
