SUBJECT: PALO VERDE NUCLEAR GENERATING STATION - NOTIFICATION OF AGE-

RELATED DEGRADATION INSPECTION (05000528/2024012,

05000529/2024012, AND 05000530/2024012) AND REQUEST FOR

INFORMATION

Dear Adam Heflin:

The purpose of this letter is to notify you that the U.S. Nuclear Regulatory Commission (NRC)

staff will conduct the age-related degradation baseline inspection at Palo Verde Nuclear

Generating Station, beginning on January 29, 2024. The inspection team will be led by Dustin

Reinert 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 NRC inspection

procedure (IP) 71111.21N.04.

The inspection will include an onsite information gathering visit by the team lead and two weeks

of onsite inspection by the team. The schedule for the inspection is as follows:

Onsite Information Gathering Visit: December 12-14, 2023

Offsite Preparation Week: January 22-26, 2024

Onsite Inspection Weeks: January 30-February 2, 2024, and February 13-16, 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 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.

A. Heflin 2

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 Dustin Reinert, the team leader, in the Region 4 Office at 817-200-1534.

Sincerely,

Signed by Gaddy, Vincent

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 December 1, 2023:

1) The maintenance rule scoping and performance criteria

2) A list of maintenance rule functional failures from the past 5 years

3) A list of 50.65 (a)(1) SSCs from the past 5 years

4) The two most recent evaluations of maintenance effectiveness required per 10 CFR 50.65(a)(3)

5) The most recent system health status for each plant system and the associated Plant Health

Committee (PHC) package if presented to the PHC and any applicable PHC procedure

documents.

6) 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.

7) 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

in the risk ranking.

8) A list of 10 CFR Part 21 Reports that were determined to be applicable to the site from the

past 5 years

9) List of preventative maintenance deferrals and preventative maintenance change requests in

or industry operating experience reviews that have been used to update aging management

activities.

Enclosure 1

11) List of RISC-1, RISC-2, and RISC-3 SSCs

12) Safety significant functions identified during the RISC categorization process and alternative

treatment requirements

13) Any self-assessments or quality assurance assessments of the aging management
