UNITED STATES NUCLEAR REGULATORY COMMISSION REGION II SAM NUNN ATLANTA FEDERAL CENTER 61 FORSYTH STREET, SW, SUITE 23T85 ATLANTA, GEORGIA 30303-8931 July 30, 2009
Mr. David A. Heacock President and Chief Nuclear Officer Virginia Electric and Power Company Innsbrook Technical Center 5000 Dominion Boulevard Glen Allen, VA 23060-6711
SUBJECT: NORTH ANNA POWER STATION - COMPONENT DESIGN BASES INSPECTION - NRC INSPECTION REPORT 05000338/2009007 AND 05000339/2009007 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, M 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 M 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 M 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 VEPCO 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 M at (404) 562-4609 or me at (404) 562-4519.
Sincerely,/RA/
Binoy B. Desai, Chief Engineering Branch 1 Division of Reactor Safety Docket Nos. 50-338, 50-339 License Nos. NPF-4, NPF-7
