REGULATORY AUDIT PLAN BY THE OFFICE OF NUCLEAR REACTOR REGULATION TURKEY POINT NUCLEAR GENERATING UNIT NO. 3 DOCKET NO. 50-250

1.0 BACKGROUND

By application dated March 2, 2015 (Agencywide Documents Access and Management System (ADAMS) Package Accession No. ML15077A213), Florida Power & Light Company (the licensee) submitted Relief Request No. 1, Revision 1, for the Fifth lnservice Inspection Interval.

The licensee needs the proposed alternative authorized by the NRC before its refueling outage in October 2015. The NRC staff needs to review proprietary calculations performed by the licensee's cor:itractor, Westinghouse Electric Company, LLC. The staff determined that the most efficient manner to review the calculations was to review them at the contractor's office in Rockville, Maryland.

NRR's Office Instruction LIC-111 (ADAMS Accession No. ML082900195) states that a regulatory audit is a planned, licensed or regulation-related activity that includes the examination of primarily non-docketed information with the intent to gain understanding, to verify information, or to identify information that will require docketing to support the basis of the licensing or regulatory decision.

2.0 REGULATORY AUDIT BASIS The staff will perform this audit to support its evaluation of whether the licensee's proposed alternative can be authorized per 10 CFR 50.55a.

3.0 REGULATORY AUDIT SCOPE OR METHODOLOGY The staff will review calculations used to support the conclusions in the licensee's application.

4.0 INFORMATION AND OTHER MATERIAL NECESSARY FOR THE AUDIT The staff intends to review the following information during the audit:

• Reference 16 to WCAP-17973-NP, Westinghouse Calculation Note, CN-MRCDA-14-27, Revision 0, "Turkey Point Units 3 and 4 Pressurizer Heater Sleeve Stress Analysis,"

January 29, 2015.

• Reference 17 to WCAP-17973-NP, Westinghouse Calculation Note, CN-PAFM-15-1, Revision 0, "Turkey* Point Units 3 and 4 Pressurizer Heater Sleeve Penetration Half-Nozzle Repair Flaw Evaluation, February 11, 2015.

• Four spreadsheets from CN-PAFM-15-1 (p. 25, 26, and 29 of CN-PAFM-15-1 references the spreadsheets):

• For the stress analysis in CN-MRCDA-14-27, the output is in the form of computer runs with multiple output files. The staff will review Computer Runs 50 and 51, which each have numerous output files. The listing is on pages 44-48 for Computer Run 50 and on pages 48-49 for Computer Run 51.

The staff will also review other documents or spreadsheets that Westinghouse identifies as being important.

5.0 TEAM ASSIGNMENTS The audit team consists of Ms. Audrey Klett, the NRC's Project Manager for Turkey Point 3 and 4; Mr. Jeffrey Poehler, Senior Materials Engineer; and Mr. David Dijamco, Materials Engineer.

6.0 LOGISTICS The audit will occur at the Westinghouse Electric Company, LLC, offices in Rockville, Maryland on August 11, 2015. The staff plans to hold a brief entrance meeting at 10:00 am and a brief exit meeting by close of business the same day.

7.0 SPECIAL REQUESTS The staff requests the licensee and its contractor to have the information listed in Section 4 readily available and accessible for the staff's review. The staff also requests that cognizant licensee and contractor staff be available to answer any questions from the staff and to track staff questions during the audit. Licensee staff can be available by telephone. The staff also requests the licensee and its contractor to provide a reasonable working space for the audit period at the audit site and the audit documents in paper as well as electronically available in a text searchable format.
