Point Beach Nuclear Plant Unit 2 - Request For Additional Information for Relief Request 2-RR MF6615 By letter dated August 13, 2015, (Agencywide Documents Access and Management System (ADAMS)

Accession Number ML15225A104), NextEra Energy submitted for U.S. Nuclear Regulatory Commission (NRC) staff review and approval Relief Request 2-RR-11, which requests an extension of inspection frequency of the primary Steam Generator (SG) nozzle to safe-end welds under American Society of Mechanical Engineers Boiler and Pressure Vessel Code, Code Case N-770-1 with conditions specified in 10 CFR50.55a(g)(6)(ii)(F) for duration of the extended license at Point Beach Nuclear Plant, Unit 2. To complete its review, the NRC staff requests the following additional information:

1. Provide axial and hoop weld residual stresses without modification to include operating conditions (i.e.

temperature and pressure).

2. On page 2 of your request, you state that relief is being requested to extend the hot leg inspection schedule to be in line with the cold leg schedule, which is approximately 7.5 years from the previous examination. However, the cold leg inspection requirements per Code Case N-770-1 require inspections at least every 7 years. Please clarify if you are also requesting for an extension of the cold leg inspection frequency.

3. In order to review NRC analysis results with the licensees, please provide K calculations for axial and circumferential through-weld flaw growth.

Please arrange a teleconference with the NRC staff, in case further clarification is needed. Otherwise, please provide your response on the docket within 30 days of the receipt of this email. Thanks Mahesh Chawla Project Manager Phone: 301-415-8371 Fax: 301-415-1222 mahesh.chawla@nrc.gov
