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 during 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 baseline inspection 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. Rudolph Bernhard,

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

visit to review probabilistic risk assessment data and identify risk significant components which

will be examined during the inspection.

DEC 2

The enclosure lists documents that will be needed prior to the information gathering visit. 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 inspection 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/

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
