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

The initiation of straight breakdown paths has been identified as the key issue of the LIB propagation channel formation scheme in the HWIFR dense atmosphere. Straight preionization trails have been suggested as means for guiding the breakdown along the designated beamlines. A multi-group Boltzmann equation solver has been constructed for estimating the capability of several preionizers to induce such trails in dense D2O vapors. A new approach capable of predicting the steady state streamer wave shape is used to estimate the minimum conditions for launching a streamer in the preionized path. The electrical resistance of the trail during the streamer propagation is evaluated with a simple one dimensional routine. Finally the transition of the streamer-induced ionized filament to a multi-kA-carrying plasma channel is simulated with a modified radiation MHD code. Other results of this study, including the determination of the preionizer intensity and the minimum applied potential required for the initiation, are presented in this paper.
