SUBJECT:

PEACH BOTTOM ATOMIC POWER STATION, UNITS 2 AND 3 -

NOTIFICATION OF CONDUCT OF A FIRE PROTECTION TEAM INSPECTION

Dear David Rhoades:

The purpose of this letter is to notify you that U.S. Nuclear Regulatory Commission (NRC) staff will conduct a fire protection team inspection at your Peach Bottom Atomic Power Station, Units 2 and 3. The inspection will be conducted in accordance with Inspection Procedure 71111 1N.05, Fire Protection Team Inspection (FPTI), dated January 1, 2020. The inspection team will be led by Leonard Cline, a Senior Reactor Inspector from the NRC Region I Office.

The inspection will verify that plant structures, systems, and components, and/or administrative controls credited in the approved fire protection program can perform their licensing basis function.

The schedule for the inspection is as follows:

Information Gathering Visit: May 28 - 30, 2024 Onsite Inspection:

Weeks of July 21, 2024 and August 4, 2024 The purpose of the information gathering visit is to obtain information and documentation needed to support the inspection and to become familiar with the stations fire protection program, fire protection features, post-fire safe shutdown capabilities, and plant layout. During the information gathering visit, the team leader will select the specific samples to be reviewed during the onsite inspection weeks.

The enclosure lists the types of documents that will be needed prior to the information gathering visit. Please provide the referenced information to the Region I office by May 20, 2024.

Following sample selection, additional documents will be requested specific to those samples.

Your cooperation and support during this inspection will be appreciated.

Electronic format is preferred. If electronic media is made available via an internet-based document management system, then document access must allow inspectors to download, save, and print the documents in the NRC's Regional office. Additionally, word-searchable documents are preferred, if available. Paper records (hard copy) are acceptable. At the end of the inspection, the documents in the teams possession will not be retained.

This document request is based on typical documents that a generic plant might have. As such, this generic document request is not meant to imply that any specific plant is required to have all of the listed documents. It is recognized that some documents listed below may not be available for your plant. In addition, the document titles listed below are based on typical industry document names; your plant specific document titles may vary.
