Optimizing nuclear plant outages: Data analytics tools and methods for enhancing resilience and efficiency
Nuclear power plant refueling outages are among the most complex phases in a plant’s operational cycle.1 During these outages, tens of thousands of activities, including maintenance and surveillance, are conducted simultaneously within a short timeframe. Typically lasting three to four weeks, these operations involve large crews of contractors with diverse skill sets performing tasks ranging from testing and surveillance to maintenance. Outages may extend longer if major backfitting or modernization projects are planned. Consequently, plant outages are expensive, incurring significant operational costs, such as contractor labor and equipment, as well as the loss of generation while the plant is off line. This can easily cost a plant operator more than $1 million a day. Therefore, there is a constant need to mitigate the economic impact on plants by reducing the frequency, duration, and risks associated with these outages.2,3

In collaboration with Dominion Engineering, Inc.
High cumulative radiological exposure (CRE) can hinder outage efficiency, compromise personnel safety, and affect overall plant performance. Join us for this Supplier Showcase webinar to learn about recent advancements in ultrasonic cleaning, advanced filtration, and chemical decontamination technologies designed to reduce source term effectively. We’ll explore real world applications, review performance data, and share lessons learned to equip you with practical insights to help lower CRE and maintain safe, efficient operations.
