SUBJECT:

CALLAWAY PLANT - NOTIFICATION OF AN NRC FIRE PROTECTION

BASELINE INSPECTION (NRC INSPECTION REPORT 05000483/2025010)

AND REQUEST FOR INFORMATION

Dear Fadi Diya:

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

Region IV staff will conduct a fire protection baseline inspection at the Callaway Plant in August

and September 2025. The inspection team will be comprised of two reactor inspectors from the

NRC Region IV office and one reactor inspector from the NRC Headquarters office. The

inspection will be conducted in accordance with Inspection Procedure 71111, Attachment

21N.05, Fire Protection Team Inspection, the NRCs baseline fire protection inspection

procedure.

The schedule for the inspection is as follows:

Information gathering visit (Remote): August 4 - 8, 2025

On-site inspection: August 25 - 30, 2025

Remote inspection: September 8 - 12, 2025

The purpose of the information gathering visit is to obtain information and documentation

needed to support the inspection and to become familiar with the fire protection program, fire

protection features, post-fire safe shutdown capabilities and plant layout. This will be completed

remotely with assistance from the resident inspectors.

The team lead will review the initial set of documents requested in the enclosure to select the

scope of structures, systems, and components for evaluation, and identify additional documents

needed to support the inspection. The enclosure to this letter provides an initial list of the

documents the team will need for review. We request that your staff transmit copies of the

documents listed in the enclosure to the NRC Region IV office for team use in preparation for

the inspection. Please provide this information so that it is available to the inspection team by

the dates listed in the enclosure.

During the inspection planning meeting(s), the team leader will discuss the following inspection

support administrative details: (1) office space size and location; (2) specific documents

requested to be made available to the team in their office spaces; (3) arrangements for reactor

site access (including radiation protection training, security, safety, and fitness for duty

requirements); and (4) the availability of knowledgeable plant staff and licensing organization

personnel to serve as points of contact during the inspection.

We request that personnel be available at the site during the inspection who are knowledgeable

regarding those plant systems required to achieve and maintain safe and stable plant

conditions, including the electrical aspects of the nuclear safety capability assessment, reactor

plant fire protection systems and features, and the station fire protection program and its

implementation.

Fire Protection Team Inspection Document Request

The documents and information requested below should generally be made available to the

inspection team prior to the inspection. Electronic format is the preferred format, except where

specifically noted. If electronic files are made available via a secure document management

service, then the remote document access must allow inspectors to download, save, and print

the documents.

If a secure document management service is utilized, it is recommended that a separate folder

be used corresponding to each item listed below. It is recommended that multiple documents

within each folder be individually entered and also combined into a ZIP file which is uploaded

into the same folder. Documents should be identified by both document number and noun

name.

To allow review before the information gathering visit, the documents requested in items A.1

thru A.11 should be made available to the team no later than July 16, 2025.

Based on review of the documentation, the team leader will identify the scope for the inspection

prior to the end of the on-site information gathering visit or in-office review of the information

obtained.

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.

To allow review before the on-site inspection week(s), all requested documents should be made

available to the team no later than July 21, 2025.
