SUBJECT:

CALLAWAY PLANT - NOTIFICATION OF INSPECTION (NRC INSPECTION

REPORT 05000458/2023003) AND REQUEST FOR INFORMATION

Dear Fadi Diya:

During the week of May 22, 2023, three inspectors from the Nuclear Regulatory

Commissions (NRC) Region IV office will perform the baseline biennial requalification

inspection at Callaway Plant, Unit 1, using NRC Inspection Procedure 71111.11B, Licensed

Operator Requalification Program.

Experience has shown that this inspection is a resource intensive inspection both for the NRC

inspectors and your staff. To minimize the impact to your onsite resources and to ensure a

productive inspection, we have enclosed a request for documents needed for this inspection.

These documents have been divided into three groups:

The first group (Section A of the enclosure) identifies information to be provided prior to

the inspection to ensure that the inspectors are adequately prepared.

The second group (Section B of the enclosure) identifies the information the inspectors

will need upon arrival at the site.

The third group (Section C of this enclosure) identifies the items which are necessary to

close out the inspection and are usually sent a few weeks after the inspectors have left

the site.

It is important that all these documents are up to date and complete to minimize the number of

additional documents requested during the preparation and/or the onsite portions of the

inspection.

F. Diya

We have discussed the schedule for these inspection activities with your staff and understand

that our regulatory contact for this inspection will be Thomas Forland of your Regulatory Affairs

organization, and Ben Bruemmer of your training organization. Our inspection dates are subject

to change based on your updated schedule of examination activities. If there are any questions

about this inspection or the material requested, please contact me, Nicholas Hernandez, at (817)

200-1118 (Nicholas.Hernandez@nrc.gov).

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, control number 3150-

0018. 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.

This letter and its enclosure 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.

Sincerely,

Nicholas Hernandez, Operations Engineer
