SUBJECT: CALLAWAY PLANT, UNIT 1 - NOTIFICATION OF INSPECTION (NRC

INSPECTION REPORT 05000483/2019003) AND REQUEST FOR

INFORMATION

Dear Mr. Diya:

During the week of July 29, 2019, two inspectors from the Nuclear Regulatory

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

inspection at the 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. In order 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 of these documents are up-to-date and complete in order to minimize the

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

the inspection.

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

that our regulatory contact for this inspection will be Mr. Rick Tiefenauer, Licensed Operator

Continuing Training (LOCT) Senior Training Supervisor 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

F. Diya 2

contact the lead inspector Nicholas Hernandez at (832) 689-9928 or by email

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, 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.

Sincerely,

/RA/
