SUBJECT: WOLF CREEK GENERATING STATION - NOTIFICATION OF AN NRC

FIRE PROTECTION BASELINE INSPECTION (NRC INSPECTION REPORT

05000482/2024012) AND REQUEST FOR INFORMATION

Dear Cleve Reasoner:

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

Region IV staff will conduct a triennial fire protection baseline inspection at the Wolf Creek

Generating Station in February 2024. The inspection team will be comprised of three reactor

inspectors from the NRC Region IV 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: January 17 - 18, 2024

• Onsite inspection: February 12 - 16, 2024, and February 26 - March 1, 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 fire protection program, fire

protection features, post-fire safe shutdown capabilities and plant layout.

The lead inspector will participate in the information gathering visit to select the scope of

structures, systems, and components for evaluation, identify additional documents needed to

support the inspection, obtain unescorted access, and meet with the key personnel who will

support the inspection. The fire inspection sample selection will require a walkdown of fire areas

in company with key personnel from your staff. The enclosure to this letter provides an initial list

of the documents the team will need for their 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 send this information so that it will arrive in the NRC Region IV office

by the dates listed in the enclosure.

During the information gathering visit, the team leader will also 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

C. Reasoner 2

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 during the on-site inspection weeks you ensure that copies of analyses,

evaluations, or documentation regarding the implementation and maintenance of the station fire

protection program, including the success path necessary to achieve and maintain the nuclear

safety performance criteria, be readily accessible to the team for their review. Of specific

interest for the fire protection portion of the inspection are those documents which establish that

your fire protection program satisfies NRC regulatory requirements and conforms to applicable

NRC and industry fire protection guidance (i.e., fire protection compliance assessment

documents). Personnel should 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.

PAPERWORK REDUCTION ACT STATEMENT

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 combined into a ZIP file which is uploaded into the

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

Electronic media on compact disc or paper records (hard copy) are also acceptable.

Where C-size paper drawings are requested, please prepare two copies. Retain one copy on

site for the Teams use during the inspection weeks. Send one copy to the team leader at the

NRC Region IV office.

To allow review before the on-site information gathering visit, the documents requested in items

A.1 thru A.26 should be made available to the team no later than January 8, 2024.

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

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.
