SUBJECT: DRESDEN NUCLEAR POWER STATION, UNITS 2 AND 3 - NOTIFICATION

OF NRC FIRE PROTECTION TEAM INSPECTION REQUEST FOR

INFORMATION: INSPECTION REPORT 05000237/2021011;

05000249/2021011

Dear Mr. 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 Dresden Nuclear

Power Station, Units 2 and 3 beginning July 12, 2021. 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): July 5, 2021

• Week 1 of onsite inspection: July 12 - 16, 2021

• Week 2 of onsite inspection: July 26 - 30, 2021

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 24, 2021.

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 July 12, 2021.

D. Rhoades -2-

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

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 10 CFR 2.390, Public Inspections,

Exemptions, Requests for Withholding.

Sincerely,
