SUBJECT:
NOTIFICATION OF MCGUIRE NUCLEAR STATION - COMPONENT DESIGN BASES INSPECTION - NRC INSPECTION REPORT 05000369, 370/2012007
Dear Mr. Repko:
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 McGuire Nuclear Station during the weeks of March 5 - 9, March 19 - 23, and April 2 - 6, 2012. The inspection team will be led by Shakur Walker, 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 December 6, 2011, Mr. Walker confirmed with Ms. K. Crane 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 February 13 - 17, 2012
Onsite weeks: March 5 - 9, March 19 - 23, and April 2 - 6, 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. John Hanna, a Region II Senior Reactor Analyst, will support Mr. Walker 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 February 6, 2012. Contact Mr. Walker 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 February 27. Mr. Walker, 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 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. Walker at (404) 997-4639 or me at (404) 997-4530.
Sincerely,
/RA/
