SUBJECT: NOTIFICATION OF NORTH ANNA POWER STATION - COMPONENT DESIGN BASES INSPECTION - U.S. NUCLEAR REGULATORY COMMISSION

INSPECTION REPORT 05000338/2015007 AND 05000339/2015007

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 (CDBI) at your North Anna

Power Station during the weeks of July 20 - 24, August 3 - 7, and August 17 - 21, 2015.

Geoffrey Ottenberg, a Senior Reactor Inspector from the NRC's Region II Office, will lead the inspection team. This inspection will be conducted in accordance with Inspection Procedure 71111.21, "Component Design Bases Inspection," issued November 29, 2013.

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 April 7, 2015, the staff 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 June 29 - July 3, 2015

• Onsite weeks: July 20 - 24, August 3 - 7, and August 17 - 21, 2015

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. Geoffrey Ottenberg, a Senior Reactor

Inspector, will be conducting all preparation activities associated with the inspection. In

addition, Mr. George MacDonald, a Region II Senior Reactor Analyst, will support Mr. Ottenberg

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 June 15, 2015.

D. Heacock 2

Additional documents may be requested during the information-gathering visit. The inspectors will try to minimize your administrative burden by specifically identifying only those documents

required for inspection preparation. The additional information will need to be available to the team in the Region II office prior to the inspection team's preparation week of July 13, 2015. During the information-gathering trip, Mr. Ottenberg will also discuss the following inspection

support administrative details: (1) availability of knowledgeable plant engineering and licensing personnel to serve as points of contact during the inspection, (2) method of tracking inspector

requests during the inspection, (3) licensee computer access, (4) working space,

(5) arrangements for site access, and (6) 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 Agencywide

Documents Access and Management

System (ADAMS). ADAMS

is accessible from the NRC

website 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. Ottenberg at 404-997-4658 or

contact me at 404-997-4607.

Sincerely,

/RA/

b. A list of the top 500 cutsets

2. From your most recent PSA

including external events and fires:

a. Two risk rankings of components from your site-specific PSA: one sorted by 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 human reliability worksheets for these items.
