SUBJECT: NOTIFICATION OF VOGTLE ELECTRIC GENERATING PLANT -

COMPONENT DESIGN BASES INSPECTION - NRC INSPECTION

REPORT 05000424/2010007 AND 05000425/2010007

Dear Mr. Tynan:

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 Vogtle Nuclear Plant during

the period of June 14-July 16, 2010. The inspection team will be led by Mr. Robert Berryman, 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 telephone conversation on March 3, 2010, Mr. Berryman confirmed, with Mr. Doug

McKinney 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 April 26-30, 2010.

• Onsite weeks: Weeks of June 14-18, June 28-July 2, and July 12-16, 2010.

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. George

MacDonald, a Region II Senior Reactor Analyst, may accompany Mr. Berryman 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

contact Mr. Berryman with any questions prior to preparing materials listed in the enclosure and

provide the referenced information to the Region II office by April 15, 2010. The inspectors will

try to minimize your administrative burden by specifically identifying only those documents

required for the inspection preparation.

SNC 2

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. Berryman at (404) 562-4817 or me

at (404) 562-4519.

Sincerely,

/RA/

INFORMATION REQUEST FOR VOGTLE ELECTRIC GENERATING PLANT

COMPONENT DESIGN BASES INSPECTION

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

CDROM. The CDROM 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 documented in the station
