SUBJECT:
MILLSTONE POWER STATION, UNITS 2 AND 3 - NOTIFICATION OF CONDUCT OF A TRIENNIAL FIRE PROTECTION BASELINE INSPECTION
Dear Mr. Stoddard:
The purpose of this letter is to notify you that U.S. Nuclear Regulatory Commission (NRC) staff will conduct a triennial fire protection baseline inspection at Millstone Power Station, Units 2 and 3, beginning in July 2019. The inspection team will be led by Ms. Carey Bickett. 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: July 9 - 11, 2019 On-Site Inspection: Weeks of July 22, 2019 and August 5, 2019 The purpose for the information gathering visit is 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, and mitigating strategies to address Title 10 of the Code of Federal Regulations (10 CFR) 50.54(hh)(2); and obtain plant specific site access training and badging for unescorted access.
An initial list of the documents that the team will review during the conduct of the inspection are listed in Enclosures 1 and 2. The team leader will contact you with any additional specific document requests prior to the information gathering visit. Your cooperation and support during this inspection will be appreciated.
If you have questions concerning this inspection, or the inspection team's information request or logistical needs, please contact Ms. Carey Bickett, Team Leader at (610) 337-5317, or via e-mail at carey.bickett@nrc.gov.
D. Stoddard 2 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.
This letter, its enclosures, and your response (if any) will be made available for public inspection and copying at http://www.nrc.gov/reading-rm/adams.html and at the NRC Public Document Room in accordance with 10 CFR 2.390, Public Inspections, Exemptions, Requests for Withholding.
Sincerely,
/RA/

Fire Protection Program Supporting Documentation If you have any questions regarding this information request, please contact Ms. Carey Bickett at (610) 337-5317 or via e-mail at carey.bickett@nrc.gov.
Electronic format is preferred, 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. Paper records (hard copy) are acceptable. At the end of the inspection, the documents in the teams possession will not be retained.
This document request is based on typical documents that a generic plant might have. As such, this generic document request is not meant to imply that any specific 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.
Due to the differences in both the design and operation between Millstone Units 2 and 3, the information is requested to be provided separately for each unit.
