INFORMATION REQUEST TO SUPPORT UPCOMING PROBLEM IDENTIFICATION AND RESOLUTION INSPECTION AT LASALLE COUNTY STATION

Dear David Rhoades:

This letter is to request information to support our scheduled Problem Identification and Resolution (PI&R) inspection beginning November 3, 2025, at LaSalle County 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 October 17, 2025. If there are any questions about the material requested or the inspection in general, please contact me at 630-829-9821 or Nirodh.Shah@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.

September 4, 2025

D. Rhoades 2

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.
