SUBJECT: ARKANSAS NUCLEAR ONE -- INFORMATION REQUEST FOR THE
CYBERSECURITY BASELINE INSPECTION, NOTIFICATION TO PERFORM INSPECTION
(05000313/2024404 AND 05000368/2024404)
Dear Doug Pehrson:
On August 19, 2024, the U.S. Nuclear Regulatory Commission (NRC) will begin a baseline
inspection in accordance with Inspection Procedure (IP) 71130.10 Cybersecurity, at your
Arkansas Nuclear One, Units 1 and 2. The inspection will be performed to evaluate and verify
your ability to meet the requirements of the NRCs Cybersecurity Rule, Title 10, Code of Federal
Regulations (CFR), Part 73, Section 54, Protection of Digital Computer and Communication
Systems and Networks.
Experience has shown that baseline inspections are extremely resource intensive, both for the
NRC inspectors and 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 IP 71130.10. This information should be
made available either in an online repository (preferred) or digital media (CD/DVD) and
delivered/available to the regional office no later than May 24, 2024. The inspection team will
review this information and, by June 21, 2024, will request the specific items that should be
provided for review.
The second group of 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 your cybersecurity program selected for review. This information will be requested for review
in the regional office prior to the inspection by July 19, 2024, as identified above.
D. Pehrson

The third group of requested documents consists of additional 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, August 19, 2024.
The fourth group of information aids the inspection team in tracking issues identified during 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 requested documents are
up to date and complete 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 Sam Graves. We understand that our regulatory contact
for this inspection is Michael Hall of your organization. If there are any questions about the
inspection or the material requested, please contact the lead inspector at 817-200-1102 or via
e-mail at samuel.graves@nrc.gov.

I.
Information Requested for In-Office Preparation
This initial request for information (i.e., Table RFI #1) concentrates on providing the inspection
team with information necessary to select appropriate components and cybersecurity program
elements to develop a site-specific inspection plan. The first RFI is used to identify the critical
digital assets or systems 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.
