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.

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/

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.

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.
