UNITED STATES NUCLEAR REGULATORY COMMISSION REGION III 2443 WARRENVILLE ROAD, SUITE 210 LISLE, IL 60532-4352

September 24, 2010

Mr. Timothy J. O'Connor Site Vice President Monticello Nuclear Generating Plant Northern States Power Company, Minnesota 2807 West County Road 75 Monticello, MN 55362-9637

SUBJECT:

MONTICELLO NUCLEAR GENERATING PLANT - NOTIFICATION TO PERFORM A TRIENNIAL FIRE PROTECTION BASELINE INSPECTION; INSPECTION REPORT 05000263/2011-006(DRS)

Dear Mr. O'Connor:

On February 7, 2011, the U.S. Nuclear Regulatory Commission (NRC) will begin a triennial fire protection baseline inspection at your Monticello Nuclear Generating Plant. This inspection will

be performed in accordance with Inspection Procedure (IP) 71111.05T, the NRC's baseline fire protection inspection procedure. The schedule for the on-site inspection activity is as follows: MSO Inspection: February 7 - 11, 2011; Information Gathering Visit: June 13 - 14, 2011; B.5.b Requirements: June 15 - 17, 2011; and Fire Protection Inspection: June 15 - 17, 2011; June 27 thru July 1, 2011; and July 11 - 15, 2011. The one-week inspection scheduled in February will be part of the triennial fire protection inspection and all hours will be charged to the inspection report. This week long inspection is scheduled as a result of the Monticello decision to withdraw their intention to comply with 10 CFR 50.48(c), National Fire Protection Association Standard (NFPA) 805. The purpose of this inspection is to review a representative sampling of single and multiple spurious issues throughout the plant to evaluate: (1) if the plant successfully addressed single and multiple spurious issues in a way that meets regulations. This includes proper classification of equipment required for safe shutdown and equipment important for safe shutdown; (2) the adequacy of the plant evaluation of multiple spurious actuation in accordance with Regulatory Guide 1.189 and NEI 00-01, Revision 2 for alternative or dedicated shutdown areas; and (3) the adequacy of any compensatory actions taken for identified non-compliances.

J. O'Connor The purpose of the information gathering visit in June 2011 is: (1) to obtain information and documentation needed to support the inspection; (2) to become familiar with the Monticello Nuclear Generating Plant fire protection programs, fire protection features, post-fire safe shutdown capabilities, and plant layout; and (3) to arrange administrative details, such as office space, availability of knowledgeable office personnel and to ensure unescorted site access privileges. Based on the latest revision to IP 71111.05T, dated December 24, 2009, changes were made to the IP, which now requires the fire protection inspection to review your actions to mitigate postulated events that could potentially cause loss of large areas of power reactor facilities due to explosions or fires. This requirement was implemented by the issuance of the Interim Compensatory Measures Order EA-02-026, Section B.5.b and the subsequent requirements of 10 CFR 50.54(hh)(2), which are collectively referred to as B.5.b requirements. During this inspection, the B.5.b requirements review will be performed during the first on-site week of the inspection starting on June 15, 2011. Experience has shown that the baseline fire protection inspections are extremely resource intensive both for the NRC inspectors and the licensee staff. In order to minimize the inspection impact on the site and to ensure a productive inspection for both organizations, we have enclosed a request for documents needed for the inspection. These documents have been divided into five groups. The first group lists information necessary to aid the inspectors in evaluating the Monticello plant progress in addr essing single and multiple spurious issues to ensure their compliance with regulations. It is requested that this information be provided to the inspector via mail or electronically no later than January 7, 2011. The second group lists information necessary to aid the inspection team in choosing specific focus areas for the inspection and become familiar with the licensing basis. It is requested that this information be provided to the lead inspector via mail or electronically no later than May 4, 2011. The third group also lists information and areas for discussion necessary to aid the inspection team in choosing specific fire protection focus areas for the inspection and to ensure that the inspection team is adequately prepared for the inspection. It is requested this information be available during the information gathering visit (June 13 - 14, 2011). The fourth group of requested documents consists of those items that the team will review, or need access to, during the inspection. Please have this information available by the first day of the second on-site inspection week (June 27, 2011). The fifth group lists the information necessary to aid the inspection team in tracking issues identified as a result of the inspection. It is requested that this information be provided to the lead inspector as the information is generated during the inspection. It is important that all of these documents are up to date and complete in order to minimize the number of additional documents requested during the preparation and/or the on-site portions of the inspection. The lead inspector for this inspection is Mr. Benny Jose. The one-week inspection visit scheduled in February 2011 will be conducted by a Region III inspector, Mr. Alan Dahbur. He can be contacted at (630) 829-9810 or via e-mail at alan.dahbur@nrc.gov. We understand that our regulatory contact for this inspection is Mr. D. Neve of your organization. If there are any questions about the inspection or the material requested, please contact the lead inspector at

(630) 829-9756 or via e-mail at benny.jose@nrc.gov.

J. O'Connor 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, 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's "Rules of Practice," a copy of this letter, its enclosure, and your response (if any), will be available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records System (PARS) component of NRC's Agencywide Documents Access and Management System (ADAMS), accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).
