SUBJECT: NOTIFICATION OCONEE NUCLEAR PLANT - COMPONENT DESIGN BASES INSPECTION - NRC INSPECTION REPORT 05000269,270,287/2011010

Dear Mr. Gillespie:

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 at your Oconee Nuclear Power Plant reactor facility dur

ing the period of August 15 - September 30, 2011. The inspection team will be led by Mr. Patrick Higgins, a Senior Reactor Inspector from the NRC's Region II Office. This inspection will be conducted in accordance with the bas

eline inspecti

on procedure, Procedure 71111.21, Component Design Bases Inspection, issued August 19, 2008.

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 discussion on April 26, 2011, Mr. Higgins confirmed, with 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: July 11 - July 15, 2011

• Week 1 of onsite inspection: August 29 - September 2, 2011

• Week 2 of onsite inspection: September 12 - September 16, 2011

• Week 3 of onsite inspection: September 26 - September 30, 2011

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 and

gathered or requested. Mr. R

udolph Ber

nhard, Region II Senior Reactor Analyst, may accompany Mr. Higgins during the information gathering

visit to review probabilistic ri

sk assessment data and identify risk significant components which will be examined duri

ng the inspection.

DEC 2 The enclosure lists documents that will be needed prior to the information gathering visi

t. Please contact Mr. Higgins with any questions prior to preparing materials listed in the enclosure and provide the referenced information to the Region II office by June 10, 2011, unless otherwise noted. The inspectors will try to minimize your administrative burden by specifically identifying only those documents required for the inspection preparation.

During the information gathering visit, the team leader will also discuss the following inspection support administrative details: office space; site, plant and information system access; required

resources; and information exchange protocol.

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 ins

pection in the NRC Public Document Room or from the Publicly Available Records (PARS) component of NRC's document system

(ADAMS). ADAMS is accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).

This letter does not contain new or amended information collection requirements subject to the

Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.). Existing information collection

requirements were approved by the Office of Management and Budget, control number 3150-

0011.

The NRC may not conduct or sponsor, and a person is not required to respond to, a request for

information or an information collection requirement unless the requesting document displays a

currently valid Office of Management and Budget control number.

Thank you for your cooperation in this matter. If you have any questions regarding the

information requested or the inspection, please contact Mr. Higgins at (404) 997-4615 or me at

(404) 997-4519.

Sincerely,

/RA/

Enclosure REQUEST FOR OCONEE NUCLEAR POWER PLANT COMPONENT DESIGN BASES INSPECTION

Please provide the information electronically in ".pdf" files, Excel, or other searchable format on

CD/DVD-ROM. The CD/DVD-ROM should be indexed and possibly hyperlinked to facilitate ease of use. Information in "lists" should contain enough information to be easily understood to

someone who has knowledge of pressurized water reactor technology.

1. From your most

recent probabilistic safety analysis (PSA) excluding external events and fires, please provide: a. Two risk rankings of components from your site-specific probabilistic safety analysis (PSA) - one sorted by Risk Achievement Worth (RAW), and the other

sorted by Birnbaum Importance. b. A list of the top 500 cutsets.

2. From your most

recent probabilistic safety analysis (PSA) including external events and fires, please provide: a. Two risk rankings of components from your site-specific probabilistic safety analysis (PSA) - one sorted by Risk Achievement Worth (RAW), and the other

sorted by Birnbaum Importance. b. A list of the top 500 cutsets.

3. Risk ranking of operator actions from your site specific PSA sorted by RAW. Provide copies of your human reliability worksheets for

these items. 4. Any pre-existing evaluation or list of components and calculations with low design margins (i.e., pumps closest to the design limit for flow or pressure, diesel generator close

to design required output, heat exchangers close to rated design heat removal, MOV risk-

margin rankings, etc.). 5. A list of station applicability evaluations/reviews performed and document

ed in the station corrective action program in the past two years for industry events, critical equipment

failures, and safety related equipment vul

nerabilities (as communicated by NRC generic communications, industry communications, 10 CFR Part 21 notifications, etc.). 6.
