On November 8, 2010, Duke Energy Carolinas, LLC (Duke Energy) submitted License Amendment Request (LAR) 2010-06, to amend Renewed Facility Operating Licenses DPR-38, DPR-47, and DPR-55 for Oconee Nuclear Station (ONS), Units 1, 2, and 3. In that submittal, Duke Energy requested that the Nuclear Regulatory Commission (NRC) review and approve a Reactor Vessel (RV) Internals inspection plan based on "Materials Reliability Program:

Pressurized Water Reactor Internals Inspection and Evaluation Guidelines (MRP-227-Rev.0)"

published by the Electric Power Research Institute (EPRI) (Reference 1).

By letter dated June 28, 2013 (Ref. 2), Duke Energy committed to provide Action Item #7 as described in an NRC Safety Evaluation Report (Ref. 3) associated with the pressurized water reactor internals inspection program's material reliability. Action Item #7 required applicants/licensees to develop plant-specific analyses to be applied to demonstrate that Babcock and Wilcox (B&W) in-core monitoring instrumentation guide tube assembly spiders and control rod guide tube spacer castings, Combustion Engineering (CE) lower support columns, and Westinghouse lower support column bodies will maintain their functionality during the period of extended operation. These analyses should also consider the possible loss of fracture toughness in these components due to thermal and irradiation embrittlement. The plant-specific analysis shall be consistent with the plant's licensing basis and the need to maintain the www.duke-energy.com Attachment 3 to this letter contains proprietary information.
