SUBJECT: SOUTH TEXAS PROJECT, UNITS 1 AND 2 - NOTIFICATION OF AN

NRC FIRE PROTECTION BASELINE INSPECTION (NRC INSPECTION

REPORT 05000498/2020011 AND 05000499/2020011) AND REQUEST FOR

INFORMATION

Dear Mr. Powell:

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 your South Texas

Project, Units 1 and 2 in January and February 2020. 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 7 and 8, 2020
  • Onsite inspection: January 27 - 31, 2020, and February 10 - 14, 2020

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 team lead will participate in the information gathering visit to select the fire areas 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 area

selection will require a walkdown of candidate 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 lead 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

G. Powell 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 onsite inspection weeks you ensure that copies of analyses,

evaluations, or documentation regarding the implementation and maintenance of the stations

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). Also, 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 stations fire protection

program and its implementation.

This letter does not contain new or amended information collections that are subject to the

Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.). The Office of Management and

Budget (OMB) approved these information collections (approval number 3150-0011). The NRC

may not conduct nor 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 OMB control number.

This letter, its enclosure, and your response (if any) will be made available for public inspection

and copying at http://www.nrc.gov/reading-rm/adams.html and at the NRC Public Document

Room in accordance with 10 CFR 2.390, Public Inspections, Exemptions, Requests for

Withholding.

Your cooperation and support during this inspection will be appreciated. If you have questions

concerning this inspection or the inspection teams information or logistical needs, please

contact John Mateychick, the team lead inspector, in the Region IV office at (817) 200-1560 or

John.Mateychick@nrc.gov.

Sincerely,

/RA/

Triennial Fire Protection 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 in the NRCs regional office.

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

be used corresponding to each item listed below. Multiple documents within each folder be

individually entered and also combined into a ZIP file which is uploading in 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.

To allow review before the onsite information gathering visit, the documents requested in

items A.1 thru A.8 should be made available to the team in the regional office no later than

December 27, 2019.

Based on a review of the above eight items, team lead should identify a preliminary list of fire

areas being considered for inspection prior to the onsite information gathering visit. During the

information gathering visit, or shortly thereafter, the fire areas selected for inspection will be

determined.

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 onsite inspection weeks, the documents listed in the attachment

should be made available to the team in the regional office no later than January 10, 2020.
