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 during the weeks of May 21 - 25, June 4 - 8, and June 18 - 22, 2012. The inspection
team will be led by Shane Sandal, 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 December 6, 2010.
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 January 4, 2012, Mr. Sandal confirmed with Mr. 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 April 30 - May 4, 2012
    *  Onsite weeks: May 21 - 25, June 4 - 8, and June 18 - 22, 2012
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. George MacDonald, a Region II Senior
Reactor Analyst, will accompany Mr. Sandal 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 provide the referenced information to the Region II office by April 23, 2012. Contact

Mr. Sandal with any questions concerning the requested information. The inspectors will try to
minimize your administrative burden by specifically identifying only those documents required
for inspection preparation.
Additional documents will be requested during the information-gathering visit. The additional
information will need to be made available to the team in the Region II office prior to the
inspection teams preparation week of May 14. Mr. Sandal, will also discuss the following
inspection support administrative details: availability of knowledgeable plant engineering and
licensing personnel to serve as points of contact during the inspection; method of tracking
inspector requests during the inspection; licensee computer access; working space;
arrangements for site access; and other applicable information.
In accordance with 10 CFR 2.390 of the NRC's "Rules of Practice," a copy of this letter and its

BASES INSPECTION - NRC INSPECTION REPORT 05000338, 339/2012007

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 during the weeks of May 21 - 25, June 4 - 8, and June 18 - 22, 2012. The inspection

team will be led by Shane Sandal, 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 December 6, 2010.

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 January 4, 2012, Mr. Sandal confirmed with Mr. Leberstien

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. George MacDonald, a Region II Senior

Reactor Analyst, will accompany Mr. Sandal 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 provide the referenced information to the Region II office by April 23, 2012. Contact

VEPCO 2

Mr. Sandal with any questions concerning the requested information. The inspectors will try to

minimize your administrative burden by specifically identifying only those documents required

for inspection preparation.

Additional documents will be requested during the information-gathering visit. The additional

information will need to be made available to the team in the Region II office prior to the

inspection teams preparation week of May 14. Mr. Sandal, will also discuss the following

inspection support administrative details: availability of knowledgeable plant engineering and

licensing personnel to serve as points of contact during the inspection; method of tracking

inspector requests during the inspection; licensee computer access; working space;

arrangements for site access; and other applicable information.

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-
