The staff will also establish a license condition for the applicant to:

• Perform boroscope and ultrasonic thickness (UT) measurements every outage until drainage is established

• Submit a report to the staff summarizing the results from the boroscope examinations and the UT measurements

• Perform UT measurements of the drywell shell, after the drainage is established from all four quadrants, during the next three refueling outages to establish a corrosion rate to demonstrate that the drywell structural integrity will be maintained through the period of extended operation The applicant understands that they will be submitting a statement on the docket and the staff will be establishing a license condition.
