UNITED STATES NUCLEAR REGULATORY COMMISSION REGION II 245 PEACHTREE CENTER AVENUE NE, SUITE 1200 ATLANTA, GEORGIA 30303-1257 October 3, 2013

Mr. Scott Site Vice President Duke Energy Corporation Oconee Nuclear Station

7800 Rochester Highway Seneca, SC 29672-0752

SUBJECT: NOTIFICATION OF OCONEE NUCLEAR STATION, UNITS 1, 2, AND 3 COMPONENT DESIGN BASES INSPECTION - NRC INSPECTION REPORT 05000269/2014007, 05000270/2014007, 05000287/2014007

Dear Mr. Batson:

The purpose of this letter is to notify you that the U.S. Nuclear Regulatory Commission (NRC) Region II staff will conduct a component design bases inspection (CDBI) at your Oconee Nuclear Station, Units 1, 2, and 3 during the weeks of February 10 - 14, March 3 - 7, and March 17 - 21, 2014. Jason Eargle, a Senior Reactor Inspector from the NRC's Region II Office, will lead the inspection team. This inspection will be conducted in accordance with the baseline inspection procedure, Procedure 71111.21, "Component Design Bases Inspection," issued August 14, 2012.

The inspection will evaluate the capability of risk-significant / low margin components to function as designed and to support proper system operation. The inspection will also include a review of selected operator actions, operating experience, and modifications.

During a telephone conversation on October 2, 2013, Mr. Eargle confirmed with Mr. Bob Meixell and Ms. Judy Smith of your staff, arrangements for an information-gathering site visit and the three-week onsite inspection. The schedule is as follows:

  • Information-gathering visit: Week of January 13-17, 2014
  • Onsite weeks: February 10 - 14, March 3 - 7, and March 17 - 21, 2014 The purpose of the information-gathering visit is to meet with members of your staff to identify risk-significant components and operator actions. Information and documentation needed to support the inspection will also be identified. Mr. Rudy Bernhard, a Region II Senior Reactor Analyst, will support Mr. Eargle during the information-gathering visit to review probabilistic risk assessment data and identify risk-significant components, which will be examined during the inspection.

The Enclosure lists documents that will be needed prior to the information-gathering visit. Please provide the referenced information to the Region II Office by December 13, 2013. Additional documents will be requested during the information-gathering visit. The inspectors will try to minimize your administrative burden by specifically identifying only those documents required for inspection preparation. The additional information will need to be available to the team in the Region II Office prior to the inspection team's preparation week of February 3, 2014. Mr. Eargle will also discuss the following inspection support administrative details: (1) availability of knowledgeable plant engineering and licensing personnel to serve as points of contact during the inspection, (2) method of tracking inspector requests during the inspection, (3) licensee computer access, (4) working space, (5) arrangements for site access, and (6) other applicable

information.

In accordance with 10 CFR 2.390 of the NRC's "Rules of Practice," a copy of this letter and its

Enclosure will be available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records (PARS) component of NRC's Agencywide Documents Access and Management System (ADAMS). ADAMS is accessible from the NRC website at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).

Thank you for your cooperation in this matter. If you have any questions, regarding the information requested or the inspection, please contact Mr. Eargle at 404-997-4632 or contact

me at 404-997-4530.

Sincerely,RA Rebecca L. Nease, Chief Engineering Branch 1 Division of Reactor Safety
