UNITED STATES NUCLEAR REGULATORY COMMISSION REGION I 2100 RENAISSANCE BOULEVARD, SUITE 100 KING OF PRUSSIA, PENNSYLVANIA 19406-2713 October 3, 2013 Mr. Michael J. Pacilio Senior Vice President, Exelon Generation Company, LLC President and Chief Nuclear Officer (CNO), Exelon Nuclear 4300 Winfield Road Warrenville, IL 60555
SUBJECT:
THREE MILE ISLAND STATION, UNIT 1 - NOTIFICATION OF CONDUCT OF A TRIENNIAL FIRE PROTECTION BASELINE INSPECTION
Dear Mr. Pacilio:
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 Three Mile Island Station, Unit 1, in January, 2014. The inspection team will be led by Keith Young from the NRC Region I Office. The team will be composed of personnel from the NRC Region I Office. The inspection will be conducted in accordance with Inspection Procedure 71111.05T, the NRC's baseline fire protection inspection procedure.
The schedule for the inspection is as follows:
Information Gathering Visit - Week of January 12, 2014 On-site Inspection - Weeks of January 26, 2014 and February 9, 2014 The purposes of the information gathering visit are to obtain information and documentation needed to support the inspection, to become familiar with the station fire protection programs, 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.
Initial lists of the documents the team will review during the conduct of the inspection are included in Enclosures 1 and 2. The team leader will contact you with any additional specific document requests prior to the information gathering visit.
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; and the availability of knowledgeable plant staff and licensing organization personnel to serve as points of contact during the inspection.
M. Pacilio 2 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 who are 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.
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 Keith Young, the team leader, in the Region I Office at 610-337-5293.
Sincerely,
/RA/

Enclosure 1 Fire Protection Program Supporting Documentation The documents and information requested below should generally be made available to the inspection team during the on-site information gathering visit for the team's use both on-site and off-site during the inspection. Electronic format is the preferred media, except where specifically noted. 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 of course always 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) (request A.3)
Fire Probabilistic Risk Assessment (PRA) Summary Document (request A.4)
Based on a review of the above four documents, the team leader should 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.
This document request is based on typical documents that plants have. As such, this generic document request is not meant to imply that your plant is required to have all of the listed documents. It is recognized that some documents listed below may not be available for your plant. In addition, the document titles listed below are based on typical industry document names; your plant specific document titles may vary. If there are any questions or concerns, contact the NRC inspection team leader.
