SUBJECT: PRAIRIE ISLAND NUCLEAR GENERATING PLANT NOTIFICATION OF NRC

FIRE PROTECTION TEAM INSPECTION REQUEST FOR INFORMATION;

INSPECTION REPORT 05000282/2022010; 05000306/2022010

Dear Mr. Domingos:

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 at your Prairie Island Nuclear

Generating Plant beginning March 28, 2022. The inspection will be conducted in accordance

with Inspection Procedure 71111.21N.05, Fire Protection Team Inspection, dated June 12,

2019.

The inspection will verify that plant structures, systems and components (SSCs) and/or

administrative controls credited in the approvedFire Protection Program can perform their

licensing basis function.

The schedule for the inspection is as follows:

Preparation week (R-III office): March 21 - 25, 2022

Week 1 of onsite inspection: March 28 - April 1, 2022

Week 2 of onsite inspection: April 11 - 15, 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 February 21, 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 March 28, 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 Ms. J. Gilliam. We understand that our regulatory

contact for this inspection is Ms. C. Seipp of your organization. If there are any questions about

the inspection or the material requested, please contact the lead inspector at 630-829-9831 or

via e-mail at Jasmine.Gilliam@nrc.gov.

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.

This letter and its enclosure 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, Part 2.390, Public Inspections,

Exemptions, Requests for Withholding.

Sincerely,
