SHEARON HARRIS UNIT 1 SG inspection report (TAC No. ME6358)

John, We have reviewed the 180-day Steam Generator (SG) inspection report from Shearon Harris Nuclear Power Plant, Unit 1, dated May 5, 2011 (Agencywide Documents Access and Management System (ADAMS)

Accession No. ML11130A111). We did not identify any significant issues but would like the following three points clarified. When you are ready to respond with your clarification we will accept either an electronic response or we can have a phone call. We will document your response in our review report.

1. For each refueling outage and SG tube inspection outage since installation of the replacement SGs, provide the cumulative effective full power months that the SGs have operated.

2. During the 2006 SG inspections, a restriction was identified approximately 22 inches from the cold-leg tube end in SG B. Discuss what inspections, if any, were performed on this tube in the fall 2010 refueling outage. In addition, discuss the results of these inspections.

3. Provide any observations on whether any new dents/dings were identified during the fall 2010 inspections and whether the dents identified during the 2006 inspections (at the 8th and 9th tube support plates in SG C) have changed. If either new dents were identified or the previous dents have changed in size, provide details regarding the cause of the new/changing indications.

We will expect a response within 30 days of the date of this email. If you choose to clarify by phone contact me so we can identify a mutually convenient time.
