SUBJECT:
ARKANSAS NUCLEAR ONE, UNIT 1 - NOTIFICATION OF INSPECTION (NRC
INSPECTION REPORT 05000313/2025003 AND 05000368/2025003) AND
REQUEST FOR INFORMATION
Dear Doug Pehrson:
During the week of July 7, 2025, two inspectors from the U.S. Nuclear Regulatory
Commissions (NRC) Region IV office will perform the baseline biennial requalification
inspection at Arkansas Nuclear One, Unit 1, using NRC Inspection Procedure 71111.11B,
Licensed Operator Requalification Program.
Experience has shown that this inspection is a resource-intensive inspection both for the NRC
inspectors and your staff. In order to minimize the impact to your onsite resources and to
ensure a productive inspection, we have enclosed a request for documents needed for this
inspection. These documents have been divided into three groups:
The first group (Section A of the enclosure) identifies information to be provided prior to
the inspection to ensure that the inspectors are adequately prepared.
The second group (Section B of the enclosure) identifies the information the inspectors
will need upon arrival at the site.
The third group (Section C of this enclosure) identifies the items which are necessary to
close out the inspection and are usually sent a few weeks after the team has left the site.
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.
We have discussed the schedule for these inspection activities with your staff and understand
that our regulatory contact for this inspection will be Joey Fields of your training organization.
Our inspection dates are subject to change based on your updated schedule of examination
activities. If there are any questions about this inspection or the material requested, please
contact me at (817) 200-1117 (thomas.farina@nrc.gov).
