Reference 1 required licensees to inspect 10% of the welds on the subject piping each refueling outage until the actions associated with GL 89-10 on motor-operated valves (MOVs) were completed. The District performed the required augmented inspections during the recently completed Second Ten-Year Inservice Inspection (ISI) interval, Reference 2. In Reference 3 the District reported that the actions associated with GL 89-10 were completed.
