Recently completed over a dozen Surveillance Test Interval Extension evaluations for a U.S. plant, and supported the License Amendment Requestion to allow the use of this application. Provided 13 Surveillance Test Interval Extension evaluations for a U.S. plant, including the Integrated Decision-making Panel review package, and provided Surveillance Test Interval Extension packages to 8 plants to support their move to “single train” refueling outages. Performed analyses to justify the high reliability of RTS/ESFAS systems to extend surveillance test intervals for components of the RTS and ESFAS to 184 days (Report WCAP-15376, “Risk-Informed Assessment of the RTS and ESFAS Surveillance Test Intervals and Reactor Trip Breaker Test and Completion Times”).
