Those repairs will be completed on an expedited basis as soon as the condition is identified.

All thread engagement inspections will be evaluated prior to the next refueling shutdown for the applicable unit.Corrective action for any fastener failing to meet standard acceptance criteria of full thread engagement will be completed prior to the end of the refueling outage.Shared systems will be completed, in the Unit 3 refueling outage as accessible.
