Inspection Procedure:
71111.21N.04, Age-Related Degradation, dated December 15,
2023 (ADAMS ML23318A426)
Inspection Dates:
Information Gathering Week: May 19, 2025
Preparation Week: September 1, 2025
Onsite Week 1: September 8, 2025
Onsite Week 2: September 22, 2025
Inspection Report: 05000325/2025010, AND 05000324/2025010
(Standalone Inspection Report)
Inspectors:
T. Su (Lead/Mechanical), G. Ottenberg (Mechanical), and P. Braxton
(Electrical)
The purpose of this letter is to notify you that three inspectors from Region II will conduct an
inspection at your site in accordance with Inspection Procedure 71111.21N.04, Age-Related
Degradation. Attachment 21N.04 is not considered a team inspection. The inspection will
evaluate the implementation of the programs regarding age related degradation, and that
structures, systems, and components (SSCs) are identified and addressed in a manner that
provides reasonable assurance of the safe operation of the Brunswick Nuclear Station, Units 1,
2, and 3. The inspectors will select samples of SSCs that are risk significant and within the
scope of the program.
On September 8, 2025, Mr. Teh-Chiun Su, a Senior Reactor Inspector from the NRCs Region
II office, will begin the inspection with an information gathering visit to the site. 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 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.
Enclosure 1 lists documents that are needed prior to the information gathering visit. Please
provide the referenced information to the Region II office or otherwise make the
documentation electronically available by one week prior to the beginning of the information
gathering visit. Additional documents may be requested during the information gathering visit.
The additional information should be provided to the Inspectors in the Region II office by May
12, 2025. During the information gathering visit, Mr. Su will also discuss the following
inspection support administrative details: (1) availability of knowledgeable plant engineering
and licensing personnel to serve as points of contact during the inspection, (2) method of
tracking inspector requests during the inspection, (3) licensee computer access, (4) working
space, (5) arrangements for site access, and (6) other applicable information.
For SSCs that have been selected for review, an initial list of the documents the inspectors
will review during the conduct of the inspection are listed in Enclosure 2. The team leader will
contact you with identified SSCs. Also, personnel should be available at the site during the
inspection who are knowledgeable regarding maintenance, surveillance, testing, inspection,
and condition monitoring programs.

Information Gathering Visit: An information gathering visit is currently scheduled the week
of May 19, 2025. During this visit, we would like to identify the component samples for this
inspection. Wed like to meet with Aging Management, Maintenance Rule, and Equipment
Reliability Program specialists to discuss the upcoming inspection and our sample selection
process. Purposes of the site visit are to: (a) discuss the scope of the planned inspection;
(b) obtain advance information to review in preparation for the inspection; (c) ensure that the
information to be reviewed is available at the beginning of the inspection; and (d) verify that
logistical issues (such as obtaining both site and computer system access and arranging the
location of the inspection team working area) will be resolved prior to inspector arrival. We
request the room to have a telephone, wireless internet access, and availability of station
procedures, corrective action program documents, and a printer.
Logistics:
Information gathering visit week: May 19, 2025
Onsite inspection weeks: September 8, and September 22, 2025
The licensee was offered the option of having an entrance meeting and the licensee
decline to have an entrance meeting. The date and time of the exit meeting will be
discussed at a later date. In addition, Id like to have a daily debrief with your inspection
support staff at a convenient time in the afternoons for both the onsite and in between
inspection weeks (Time TBD, approximately 30 minutes).
We will need a conference room as workspace for the inspectors. We will also need an area
available for conducting interviews. Please provide access to your document system and Wi-
Fi access.
During the information gathering visit, please provide info on (1) conference room location &
phone number, (2) cafeteria location/hours, and (3) engineering staff normal working hours.
Also, please let me know if there are any potential resource conflicts during our onsite weeks
(Fridays off, EOP drills, management retreats) and well do our best to accommodate.
