SUBJECT: NORTH ANNA NUCLEAR PLANT (UNIT 1 AND 2) - NOTIFICATION OF A TRIENNIAL FIRE PROTECTION BASELINE INSPECTION (NRC INSPECTION REPORT NOS. 05000338/2018011 AND 05000339/2018011)

Dear Mr. Heacock:

The purpose of this letter is to notify you that the U.S. Nuclear Regulatory Commission (NRC) staff will conduct a triennial fire protection baseline inspection at North Anna Nuclear Plant, Units 1 and 2. The inspection team will be led by Rodney Fanner, a Senior Reactor Inspector from the NRC Region II Office. The team will be composed of personnel from the NRC Region II Office. The inspection will be conducted in accordance with IP 71111.05T, the NRC's baseline fire protection inspection procedure, dated January 31, 2013.

On January 30, 2018, during a telephone conversation between Mr. D. Taylor, Licensing, and Mr. R. Fanner of our respective staffs confirmed arrangements for an onsite information-

gathering visit and two-weeks of onsite inspection. The schedule for the inspection is as follows:

• Information Gathering Visit: April 2 - 4, 2018 * Week 1 of onsite inspection: May 7- 11, 2018 * Week 2 of onsite inspection: May 21- 25, 2018 The purposes of the information gathering visit are to obtain information and documentation needed to support the inspection, to become familiar with the North Anna Nuclear Plant fire protection program, fire protection features, post-fire safe shutdown capabilities, plant layout, mitigating strategies to address Title 10 of the Code of Federal Regulations (10 CFR) 50.54(hh)

(2); and, as necessary, obtain plant specific site access training and badging for unescorted site access.

An initial list of the documents the team will review during the conduct of the inspection is listed in Enclosures 1 and 2. The team leader will contact you with any additional specific document requests prior to the information gathering visit.

D. Stoddard 2 During the information gathering visit, the team will also discuss the following inspection support administrative details: office space size and location; specific documents requested to be made available to the team in their office spaces; arrangements for reactor site access (including radiation protection training, security, safety and fitness for duty requirements); and the availability of knowledgeable plant staff and licensing organization personnel to serve as points of contact during the inspection.

We request that during the on-site inspection weeks you ensure that copies of analyses, evaluations or documentation regarding the implementation and maintenance of the station fire protection program, including post-fire safe shutdown capability, be readily accessible to the team for their review. Of specific interest for the fire protection portion of the inspection are those documents which establish that your fire protection program satisfies NRC regulatory requirements and conforms to applicable NRC and industry fire protection guidance (i.e., fire protection compliance assessment documents). For the 10 CFR 50.54(hh) (2) portion of the inspection, those documents implementing your mitigating strategies and demonstrating the management of your commitments for the strategies are of specific interest. Also, personnel should be available at the site during the inspection that is knowledgeable regarding those plant systems required to achieve and maintain safe shutdown conditions from inside and outside the control room, including the electrical aspects of the relevant post-fire safe shutdown analyses, reactor plant fire protection systems and features, and the station fire protection program and its implementation. This letter does not contain new or amended information collection requirements subject to the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.). Existing information collection requirements were approved by the Office of Management and Budget, under control number 3150 0011. The NRC may not conduct or sponsor, and a person is not required to respond to, a request for information or an information collection requirement unless the requesting document displays a currently valid Office of Management and Budget control number.

In accordance with 10 CFR 2.390 of the NRC Rules and Practices, a copy of this letter and its enclosures will be available electronically for public inspection in the NRC Public Document Room or from the Publically Available Records (PARS) component of NRCs document system (ADAMS). ADAMS is accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.hmtl (the Public Electronic Reading Room).

D. Stoddard 3 Your cooperation and support during this inspection will be appreciated. If you have questions concerning this inspection, or the inspection team's information or logistical needs, please contact Rodney Fanner, the team leader, in the Region II Office at 404-997-4638 or me at 404-997-4521.

Sincerely,/RA/ Scott M. Shaeffer, Chief Engineering Branch 2 Division of Reactor Safety Docket Nos.: 50-338; 50-339 License No.: DPR-32 and DPR-37

Electronic format is the preferred media, except where specifically noted, if readily available (The preferred file format is searchable ".pdf" files). If electronic media is made available via an internet based remote document management system, then the remote document access must allow inspectors to download, save, and print the documents in the NRC's regional office. Electronic media on compact disc or paper records (hard copy) are acceptable. At the end of the inspection, the documents in the team's possession will not be retained.

Approximately three weeks before the on-site information gathering visit, the following documents should be made available to the team leader for review in the regional office: * Post-fire Safe Shutdown or Alternative Shutdown Analysis (request A.1) * Fire Hazards Analysis (request A.2) * Individual Plant Examination for External Events (Fire Chapter ONLY) (request A.3) Based on review of the above three documents, the team leader will identify a preliminary list of fire areas being considered for inspection prior to the on-site information gathering visit. During the information gathering visit, or shortly thereafter, the fire areas selected for inspection will be determined.
