During a normal refueling outage in a pressurized water reactor, nondestructive inspection of steam generator tubes is used extensively to maximize plant safety and to maximize its generating production capacity during the next fuel cycle. The problem is to identify and implement the most cost-effective in-service inspection (ISI) policy at as low as reasonably achievable radiation exposure. This paper presents a new methodology to develop plant-specific sampling strategies and acceptance criteria for ISI of steam generator tubes using a risk assessment approach. Based on plant-specific data augmented by industry data, the methodology is currently being applied to Salem units 1 and 2 steam generator tube inspections during refueling outages IRF10 and 2RF6.
