SUBJECT:
NORTH ANNA POWER STATION - COMPONENT DESIGN BASES
INSPECTION - NRC INSPECTION REPORT 05000338/2009007 AND
Dear Mr. Heacock
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 North Anna Power
Station Units 1 and 2 during the weeks of November 2-6, November 16-20, and December 7-11,
2009. The inspection team will be led by Mr. S. Rose, a Senior Operations 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 July 28, 2009, Mr. Rose confirmed with Mr. J. Leberstien 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 October 19-23, 2009.
Onsite weeks: November 2-6, November 16-20, and December 7-11, 2009.
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. W. Rogers, a Region II Senior Reactor
Analyst, may accompany Mr. Rose during the information gathering visit to review probabilistic
risk assessment data and identify risk significant components which will be examined during the
inspection.
Please provide the information requested in the enclosure to the Region II office by October 13,
2009. The enclosure lists documents that will be needed prior to the information gathering visit.
The inspectors will try to minimize your administrative burden by specifically identifying only
those documents required for the inspection preparation. Contact Mr. Rose with any questions
related to the information request. During the information gathering visit, the team leader will
also discuss the following inspection support administrative details: office space; supplemental
documents requested to be made available to the team in the Region II office prior to the
2
inspection preparation week of October 26-30, 2009; arrangements for site access; and the
availability of knowledgeable plant engineering and licensing personnel to serve as points of
contact during the inspection.
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).
Thank you for your cooperation in this matter. If you have any questions regarding the
information requested or the inspection, please contact Mr. Rose at (404) 562-4609 or me at
(404) 562-4519.
Sincerely,
/RA/

INFORMATION REQUEST FOR NORTH ANNA POWER STATION UNITS 1 AND 2
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 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.
