SUBJECT: MCGUIRE NUCLEAR STATION - INFORMATION REQUEST FOR THE
CYBERSECURITY BASELINE INSPECTION, NOTIFICATION TO PERFORM
INSPECTION 05000369/2024403; 05000370/2024403
Dear Edward Pigott:
On June 24, 2024, the U.S. Nuclear Regulatory Commission (NRC) will begin a baseline
inspection in accordance with Inspection Procedure (IP) 71130.10 Cybersecurity, Revision 0 at
your McGuire Nuclear Station. The inspection will be performed to evaluate and verify your
ability to provide assurance that your digital computer and communication systems and
networks associated with safety, security, or emergency preparedness (SSEP) functions are
adequately protected against cyber-attacks in accordance with Title 10 of the Code of Federal
Regulations (10 CFR) 73.54 and the U.S. Nuclear Regulatory Commission (NRC) approved
cyber security plan (CSP). The onsite portion of the inspection will take place during the week of
June 24, 2024.
Experience has shown that baseline inspections are extremely resource intensive, both for the
NRC inspectors and the licensee staff. 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 cybersecurity IP. This information should
be made available electronically no later than May 10, 2024. The inspection team will review
this information and, by May 17, 2024, will request the specific items that should be provided for
review. This 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 cybersecurity inspection. We
request that the information provided from the second RFI be made available to the regional
office prior to the inspection by June 14, 2024.
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, June 24, 2024.April 10, 2024
E. Pigott 2
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 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 Philipp Braaten. We understand that our regulatory
contact for this inspection is Jeff Thomas of your organization. If there are any questions about
the inspection or the material requested, please contact the lead inspector at (404) 997-4651 or
via e-mail at Philipp.braaten@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 Web site at
http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).

I. 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 cybersecurity 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 May
10, 2024, 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 May 17, 2024, 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 cybersecurity inspection. We request that
the additional information provided from the second RFI be made available to the regional
office prior to the inspection by June 14, 2024. All requests for information shall follow the
guidance document U.S. NRC - Guidance Document for Development of the Request for
Information (RFI) and Notification Letter for Full Implementation of the Cyber Security
Inspection, referenced above.
The required Table RFI #1 information shall be provided electronically to the lead inspector by
May 10, 2024. The preferred file format for all lists is a searchable Excel spreadsheet file. The
information 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.
