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

Tritium instrumentation is required for the protection of personnel in any facility handling significant quantities of tritium. In such facilities, in a chronic or accidental tritium release situation, tritium may be present in the air as tritiated hydrogen gas (HT, DT, T2) or tritiated water vapour (HTO, T2O, DTO). For health protection purposes, the airborne tritium concentration of each species should be determined separately since the two species represent very different radiological hazards. This paper describes a tritium monitor that is capable of measuring the airborne concentration of tritium species in the range from 0.037 MBq/m3 (1 µCi/m3) to 7.4×104 MBq/m3 (2.0×106 µCi/m3) with a resolution of 0.074 MBq/m3 (2 µCi/m3) in the lowest range. The measurement principle is based on the separation of tritium species by a permeable membrane and the measurement of sample air activities by conventional ion chamber based tritium monitors.
