SUBJECT: DIABLO CANYON POWER PLANT - NOTIFICATION OF INSPECTION (NRC

INSPECTION REPORT 05000275/2021002, 05000323/2021002) AND

REQUEST FOR INFORMATION

Dear Mr. Welsch:

During the week of May 17, 2021, three inspectors from the Nuclear Regulatory

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

inspection at Diablo Canyon Power Plant, 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.

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

that our regulatory contact for this inspection will be Ms. Amanda Sorensen of your regulatory

services 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, Bryan Bergeon at (815) 847-8388

(bryan.bergeon@nrc.gov).

J. Welsch 2

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,
