SUBJECT: SEABROOK STATION - REQUEST FOR INFORMATION AND NOTIFICATION

OF CONDUCT OF IP 71111.21.N.04, AGE-RELATED DEGRADATION,

REFERENCE INSPECTION REPORT 05000443/2024011

Dear Bob Coffey:

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 Seabrook

Station in April 2024. Joseph Schoppy, 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 February 5, 2024

• Onsite inspection: Weeks of April 8 and April 22, 2024

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 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 and the

availability of knowledgeable plant staff and licensing organization personnel to serve as points

of contact during the inspection.

B. Blair 2

For SCs 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. The team leader will contact you

with identified SCs by February 23, 2024. 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 Title 10 of the 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,

Enclosure 1: Documents Requested for Information Gathering Visit

The following information is requested by February 5, 2024, 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 must 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.

Contact Information:

Team Lead: Joseph Schoppy

Email: Joseph.Schoppy@nrc.gov

Telephone: (610) 337-5286

Documents Requested:

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) A list of most recent system health status for High Safety Significance (HSS) and

degraded Low Safety Significance (LSS) systems as defined in the Seabrook

maintenance rule procedures.

4) The most recent evaluation of maintenance effectiveness required per 10 CFR

50.65(a)(3).

5) The maintenance rule scoping document and performance criteria.

6) List of corrective action documents associated with component failures, 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.

7) A list of Part 21 Reports applicable to the site from the past 5 years.
