SUBJECT:
LIMERICK GENERATING STATION, UNITS 1 AND 2 - REQUEST FOR
INFORMATION AND NOTIFICATION OF CONDUCT OF IP 71111.21.N.04,
AGE-RELATED DEGRADATION, REFERENCE INSPECTION REPORT
05000352/2023010 AND 05000353/2023010
Dear David Rhoades:
The purpose of this letter is to notify you that the U.S. Nuclear Regulatory Commission (NRC)
staff will conduct IP 71111.21N.04, Age-Related Degradation baseline inspection at the
Limerick Generating Station in November 2023. Jeff Kulp, a Senior Reactor Inspector from the
NRCs Region I Office, will lead the inspection team. The team will be composed of personnel
from the NRC Region I Office. The inspection will be conducted in accordance with IP
71111.21N.04 (ADAMS Accession No. ML22210A107). The inspection will evaluate the
implementation of the programs and activities to determine on a sampling basis that age-related
degradation of structures and components (SCs) is identified and addressed.
The schedule for the inspection is as follows:
Information gathering visit: Week of October 10, 2023
Onsite inspection: Weeks of November 13 through November 27, 2023
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 SCs 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 the attached Enclosure.

During the information gathering visit, the team leader 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 and
the availability of knowledgeable plant staff and licensing organization personnel to serve as
points of contact during the inspection.
For SCs that the inspection will review, an initial list of the documents the team will review
during the conduct of the inspection are also listed in the Enclosure. The team leader will
contact you with identified SCs by October 27, 2023. 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 Code of Federal Regulations (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 component
of NRCs document system (ADAMS). ADAMS is accessible from the NRC website
(http://www.nrc.gov/reading-rm/adams.html).
This baseline inspection and the supporting inspection procedure and documentation template
are new to the Reactor Oversight Process this year. As such, please communicate with the
team lead readily if there are questions as to document scope or suggestions to better
accomplish this process.
Sincerely,
Mel Gray, Chief
Engineering Branch 1

Enclosure: Documents Requested for Information Gathering Visit
Enclosure
The following information is requested by October 10, 2023, which is the first day of the
information gathering trip. 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 should allow inspectors to download, save, and print the documents in the
NRC's regional office. Electronic media on compact disc or paper records (hard copy) 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 of the
listed documents. In addition, your plant specific document titles may vary from the document
titles listed below.
