SUBJECT: LASALLE COUNTY STATION UNITS 1 AND 2- NOTIFICATION OF NRC
FIRE PROTECTION TEAM INSPECTION REQUEST FOR INFORMATION;
INSPECTION REPORT NUMBERS 05000373/2023011 AND 05000374/2023011
Dear David Rhoades:
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 LaSalle County
Station, Units 1 and 2 beginning May 22, 2023. 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 structures, systems, and components (SSCs) and/or
administrative controls credited in the approved Fire Protection Program (FPP) can perform
their licensing basis function.
The schedule for the inspection is as follows:
Preparation week (R-III office): May 15 - 19, 2023
Week 1 of onsite inspection: May 22 - 26, 2023
Week 2 of onsite inspection: June 05 - 09, 2023
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 May 01, 2023. 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 May 22, 2023. 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.
