SUBJECT:
DONALD C. COOK NUCLEAR PLANT - INFORMATION REQUEST FOR THE CYBER-SECURITY BASELINE INSPECTION, NOTIFICATION TO PERFORM INSPECTION
Dear Kelly Ferneau:
On December 1st, 2025, the U.S. Nuclear Regulatory Commission (NRC) will begin a baseline inspection in accordance with Inspection Procedure (IP) 71130.10 Cyber-Security, Revision 0 at your Donald C. Cook Nuclear Plant. The inspection will be performed to evaluate and verify that the Donald C. Cook Nuclear Power Stations digital computer and communication systems and networks associated with safety, security, or emergency preparedness (SSEP) functions are adequately protected against cyberattacks in accordance with Title 10 of the Code of Federal Regulations (10 CFR), Part 73, Section 54, Protection of Digital Computer and Communication Systems and Networks, and the U.S. Nuclear Regulatory Commission (NRC) approved cybersecurity plan (CSP). The onsite portion of the inspection will take place December 01 - 05, 2025.
Experience has shown that baseline 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 parties, we have enclosed a request for documents needed for the inspection. These documents have been divided into four groups.
The first group specifies information necessary to assist the inspection team in choosing the focus areas (i.e., sample set) to be inspected by the cyber-security IP. This information should be made available electronically no later than September 26, 2025. The inspection team will review this information and, by October 17, 2025, will request the specific items that should be provided for review.
The second group of additional requested documents will assist the inspection team in the evaluation of the critical systems and critical digital assets (CSs/CDAs), defensive architecture, and the areas of the licensees CSP selected for the cyber-security inspection. This information will be requested for review in the regional office prior to the inspection by November 14, 2025, as identified above.
August 20, 2025
K. Ferneau 2
The third group of requested documents consists of those items that the inspection team will review, or need access to, during the inspection. Please have this information available by the first day of the onsite inspection, December 01, 2025.
The fourth group of information is 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 Alan Dahbur. We understand that our regulatory contact for this inspection is Matthew Hohlek 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 email at Alan.dahbur@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.
In accordance with 10 CFR 2.390, Public Inspections, Exemptions, Requests for Withholding, of the NRC's Rules of Practice, a copy of this letter and its enclosure will be available electronically for public inspection in the NRCs Public Document Room or from the Publicly Available Records (PARS) component of the NRC's Agencywide Documents Access and Management System (ADAMS). ADAMS is accessible from the NRC website at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).
Sincerely, Alan Dahbur, Senior Reactor Inspector Engineering Branch 2 Division of Operating Reactor Safety Docket Nos. 05000315 and 05000316 License Nos. DPR-58 and DPR-74

Information Requested for In-Office Preparation The initial request for information (i.e., first RFI) concentrates on providing the inspection team with the general information necessary to select appropriate components and CSP elements to develop a site-specific inspection plan. The first RFI is used to identify the list of critical systems and critical digital assets (CSs/CDAs) plus operational and management (O&M) security control portions of the CSP to be chosen as the sample set required to be inspected by the cyber-security IP. The first RFIs requested information is specified below in Table RFI #1. The Table RFI #1 information is requested to be provided to the regional office by September 26, 2025, or sooner, to facilitate the selection of the specific items that will be reviewed during the onsite inspection weeks.
The inspection team will examine the returned documentation from the first RFI and identify/select specific systems and equipment (e.g., CSs/CDAs) to provide a more focused follow-up request to develop the second RFI. The inspection team will submit the specific systems and equipment list to your staff by October 17, 2025, which will identify the specific systems and equipment that will be utilized to evaluate the CSs/CDAs, defensive architecture, and the areas of the licensees CSP selected for the cyber-security inspection. We request that the additional information provided from the second RFI be made available to the regional office prior to the inspection by November 14, 2025.
The required Table RFI 1 information shall be provided electronically to the lead inspector by September 26, 2025. If a compact disk (CD) is provided, please provide four copies (one for each inspector/contactor). The preferred file format for all lists is a searchable Excel spreadsheet file. These files should be indexed and hyper-linked to facilitate ease of use. If you have any questions regarding this information, please call the inspection team leader as soon as possible.
