SUBJECT:
GRAND GULF NUCLEAR STATION - NOTIFICATION OF AGE-RELATED
DEGRADATION INSPECTION (05000416/2026014) AND REQUEST FOR
INFORMATION
Dear Brad Kapellas:
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 the
Grand Gulf Nuclear Station, beginning on August 17, 2026. The inspection team will be led by
Fabian Thomas 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 IP
71111.21N.04.
The inspection will include an onsite information gathering visit by the team leader and one
week of onsite inspection by the team. The schedule for the inspection is as follows:
Onsite Information Gathering Visit: June 29 - July 2, 2026
Offsite Preparation Week: August 10 - 15, 2026
Onsite Inspection Week: August 17 - 20, 2026
Offsite Inspection Week: August 31 - September 3, 2026
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.

For SSCs that the inspection will review, an initial list of the documents the team will review
during the conduct of the inspection are listed in enclosure 2. (Enclosure 3 lists the team
members and their contact information). 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.
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, under 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 of the NRC rules and practices, a copy of this letter and its
enclosures will be available electronically for public inspection in the NRC public document
room or from the publicly available records (PARS) component of NRCs document system
(ADAMS). ADAMS is accessible from the NRC Web site.
Your cooperation and support during this inspection will be appreciated. If you have questions
concerning this inspection, or the inspection team's information or logistical needs, please
contact Fabian Thomas, the team leader, in the Region 4 Office at 817-200-1126.
Sincerely,

Documents Requested Prior to Information Gathering Visit
The documents and information requested below should generally be made available to the
inspection team for the team's use both onsite and offsite during the information gathering visit.
Electronic format is the preferred media. If electronic media is made available via an internet
based remote document management system, then the remote document access must allow
inspectors to download, save, and print the documents in the NRC's regional office. Electronic
media on compact disc or paper records (hardcopy) are acceptable. At the end of the
inspection, the documents in the team's possession will not be retained.
This document request is based on typical documents that a generic plant might have. As such,
this document request is not meant to imply that any specific plant is required to have all the
listed documents. In addition, your plant-specific document titles may vary from the document
titles listed below. We also request that the information provided be sorted by the list below.
Documents requested by June 22, 2026:
1) A list of 50.65 (a)(1) SSCs from the past 5 years
2) A list of maintenance rule functional failures from the past 5 years
3) The two most recent evaluations of maintenance effectiveness required per Title 10 CFR
50.65(a)(3)
4) Maintenance rule scoping and performance criteria document
5) List of preventative maintenance deferrals and preventative maintenance change requests in
the last 5 years
6) Equipment reliability characterization and preventative maintenance program procedures
7) A list of Title 10 CFR Part 21 Reports that were determined to be applicable to the site from
the past 5 years
8) List of corrective action documents associated with component failures, applicable corrective
action program trend codes, or keyword search of aging, age-related, wear, accelerated
wear, corrosion, abnormal wear, accelerated degradation, and abnormal degradation
from the past 5 years. Please include a short description of the issue in the system generated
listing.
9) A list of top 100 most risk-significant structures and components according to the site-specific
probabilistic risk assessment (PRA). If possible, designate the component as active or passive

Committee (PHC) package if presented to the PHC and any applicable PHC procedure
documents.
E1- 2
11) Aging management programs and basis documents. Please also include any plant-specific
or industry operating experience reviews that have been used to update aging management
