AND REQUEST FOR INFORMATION
Dear Doug Pehrson:
The purpose of this letter is to notify you that the U.S. Nuclear Regulatory Commission (NRC)
staff will conduct the IP 71111.21N.04, Age-Related Degradation baseline inspection at
Arkansas Nuclear One, Units 1 and 2, beginning on March 24, 2025. The inspection team will
be led by Wes Cullum from the NRC Region 4 Office. The team will be composed of three
personnel from the NRC Region 4 Office. The inspection will be conducted in accordance with
The inspection will include an onsite information gathering visit by the team lead and two weeks

Onsite Information Gathering Visit: January 21-23, 2025
Offsite Preparation Week: March 17-20, 2025
Onsite Inspection Weeks: March 24-27, 2025, and April 7-10, 2025
The purpose of the information gathering visit is to become familiar with the station
maintenance, surveillance, testing, inspection, and condition monitoring programs, become
familiar with plant layout, support identification of structures, systems, and components (SSCs)
that will be reviewed during the inspection, and, as necessary, obtain plant specific site access
training and badging for unescorted site access. An initial list of documents that the team will
review during the information gathering visit are listed in enclosure 1.
During the information gathering visit, the team will also discuss the following inspection support
administrative details: office space size and location; specific documents requested to be made
available to the team in their office spaces; arrangements for reactor site access (including
radiation protection training, security, safety, and fitness for duty requirements); and the
availability of knowledgeable plant staff and licensing organization personnel to serve as points
of contact during the inspection.
