INSPECTION REQUEST FOR INFORMATION; INSPECTION
REPORT 05000282/2019012; 05000306/2019012
Dear Mr. Sharp:
On June 24, 2019, the U.S. Nuclear Regulatory Commission (NRC) will begin a Triennial Fire
Protection Baseline Inspection at your Prairie Island Nuclear Generating Plant, Unit 1 and 2.
This inspection will be performed in accordance with Inspection Procedure (IP) 71111.05XT,
the NRCs baseline National Fire Protection Association 805 Fire Protection IP.
The IP 71111.05XT requires the Fire Protection Inspection to review your actions to mitigate
postulated events that could potentially cause loss of large areas of power reactor facilities
due to explosions or fires. This requirement was implemented by the issuance of the Interim
Compensatory Measures Order EA-02-026, Section B.5.b and the subsequent requirements of
Title 10 of the Code of Federal Regulations, Part 50.54(hh)(2), which are collectively referred to
as B.5.b requirements. During this inspection, the B.5.b requirements review will be performed
during the first onsite week of the inspection starting on June 26, 2019.
The schedule for the onsite inspection activity is as follows:
- Information Gathering Visit: June 24-25, 2019;
- B.5.b Requirements: June 26-28, 2019; and
- Fire Protection Inspection: July 8-12, 2019, and July 22-26, 2019.
The purpose of the information gathering visit is: (1) to obtain information and documentation
needed to support the inspection; (2) to become familiar with the Prairie Island Fire Protection
Program, fire protection features, post-fire safe shutdown capabilities, and plant layout; and
(3) to arrange administrative details, such as office space, availability of knowledgeable office
personnel, and to ensure unescorted site access privileges.
S. Sharp -2-
Experience has shown that the baseline fire protection 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 four groups.
- The first group lists information necessary to aid the inspection team in choosing specific
focus areas for the inspection. It is requested that this information be provided to the
lead inspector via mail or electronically no later than June 7, 2019.
- The second group also lists information and areas for discussion necessary to aid the
inspection team in choosing specific fire protection focus areas for the inspection and
to ensure that the inspection team is adequately prepared for the inspection. It is
requested this information be available during the information gathering visit
(June 24, 2019).
- The third 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 second onsite inspection week (July 8, 2019).
- The fourth 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. Alan Dahbur. We understand that our regulatory
contact for this inspection is Ms. Pam Johnson of your organization. If there are any questions
about the inspection or the material requested, please contact the lead inspector at
630-829-9810 or via e-mail at Alan.Dahbur@nrc.gov.
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 10 CFR 2.390, Public Inspections, Exemptions, Requests for Withholding.

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.
