SUBJECT: DAVIS-BESSE NUCLEAR POWER STATION, UNIT 1 NOTIFICATION OF NRC
FIRE PROTECTION TEAM INSPECTION REQUEST FOR INFORMATION:
INSPECTION REPORT 05000346/2022011
Dear Mr. Brown:
The purpose of this letter is to notify you that the U.S. Nuclear Regulatory Commission (NRC)
Region III staff will conduct a Fire Protection Team Inspection (FPTI) at your Davis-Besse
Nuclear Power Station, beginning October 3, 2022. The inspection will be conducted in
accordance with IP 71111.21N.05, Fire Protection Team Inspection (FPTI), dated
June 12, 2019.
The inspection will verify that plant Systems, Structures, and Components (SSCs) and/or
administrative controls credited in the approved Fire Protection Program (FPP) can perform
their licensing basis functions.
The schedule for the inspection is as follows:
Preparation week (R-III office): September 26, 2022
Week 1 of onsite inspection: October 03 - 07, 2022
Week 2 of onsite inspection: October 17 - 21, 2022
Experience has shown that the baseline fire protection team 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 three groups.
The first group lists information necessary to aid the inspection team in choosing specific focus
areas for the inspection and to ensure that the inspection team is adequately prepared for the
inspection. It is requested that this information be provided to the lead inspector via mail or
electronically no later than September 05, 2022.
The second 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 first onsite inspection week October 03, 2022.

The third 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 onsite portions of
the inspection.
The lead inspector for this inspection is Mr. B. Jose. If there are any questions about the
inspection or the material requested, please contact the lead inspector at 630-829-9756 or via
Cell Phone, 847-715-8887 or via e-mail at Benny.Jose@nrc.gov. This letter, its enclosure, 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 Title 10 of the Code of Federal Regulations (10 CFR) 2.390, Public
Inspections, Exemptions, Requests for Withholding.
