INFORMATION REQUEST TO SUPPORT UPCOMING PROBLEM
IDENTIFICATION AND RESOLUTION INSPECTION AT BYRON STATION
Dear David Rhoades:
This letter is to request information to support our scheduled Problem Identification and
Resolution (PI&R) inspection beginning September 15, 2025, at Byron Station. This inspection
will be performed in accordance with the NRC baseline Inspection Procedure 71152, Problem
Identification and Resolution.
Experience has shown that these inspections are extremely resource intensive both for the
NRC inspectors and the utility staff. In order to minimize the impact that the inspection has on
the site and to ensure a productive inspection, we have enclosed a list of documents required
for the inspection.
The documents requested are copies of condition reports and lists of information necessary
to ensure the inspection team is adequately prepared for the inspection. The information
requested prior to the inspection may be provided in either CD-ROM/DVD or other online
access and should be ready for NRC review by August 25, 2025. If there are any questions
about the material requested or the inspection in general, please contact me at 630-829-9884
or Thomas.Hartman@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.
