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).

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.
