SUBJECT: JOSEPH M. FARLEY NUCLEAR PLANT, UNIT 2 -REVIEW OF THE STEAM GENERATOR TUBE INSERVICE INSPECTION REPORT FOR THE FALL 2014 REFUELING OUTAGE (TAC NO. MF6207)

Dear Mr. Pierce:

By letter dated May 11, 2015 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML15131A333), Southern Nuclear Operating Company, Inc. (the licensee), submitted information summarizing the results of the 2014 steam generator tube inspections performed at Joseph M. Farley Nuclear Plant, Unit 2. These inspections were performed during refueling outage 23. The licensee provided additional information concerning the inspections in a letter dated August 28, 2015 (ADAMS Accession No. ML 15240A372). The NRC staff has completed its review of these reports and concludes that the licensee provided the information required by their Technical Specifications and that no additional up is required at this time. The NRC staff's review is enclosed. If you have any questions, please me at 301-415-1009 or via e-mail at Shawn.Williams@nrc.gov. Docket No. 50-364

Sincerely,Shawn Williams, Project Manager Plant Licensing Branch, 11-1 Division of Operating Reactor Licensing Office of Nuclear Reactor Regulation REVIEW OF THE 2014 STEAM GENERATOR TUBE INSPECTIONS JOSEPH M. FARLEY NUCLEAR PLANT. UNIT 2 DOCKET No. 50-364 TAC NO. MF6207 By letter dated May 11, 2015 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML 15131A333), Southern Nuclear Operating Company, Inc. (the licensee), submitted information summarizing the results of the 2014 steam generator (SG) tube inspections performed at Joseph M. Farley Nuclear Plant (Farley), Unit 2. These inspections were performed during refueling outage 23. The licensee provided additional information concerning the inspections in a letter dated August 28, 2015 (ADAMS Accession No. ML 15240A372). Farley, Unit 2, has three Westinghouse Model 54F replacement steam generators, each containing 3,592 thermally treated Alloy 690 tubes. These SGs were installed in 2001. The tubes have a nominal outside diameter of 0.875 inches, a nominal wall thickness of 0.050 inches, and are supported by stainless steel tube support plates and stainless steel anti-vibration bars. The licensee provided the scope, extent, methods, and results of the Farley, Unit 2, SG tube inspections in the documents referenced above. In addition, the licensee described corrective actions (i.e. tube plugging) taken in response to the inspection findings. Based on a review of the information provided by the licensee, the NRC staff concludes that the licensee provided the information required by the Technical Specifications. In addition, the NRC staff concludes that there are no technical issues that warrant follow-up action at this time since the inspections appear to be consistent with the objective of detecting potential tube degradation and the inspection results appear to be consistent with industry operating experience at similarly designed and operated units.
