SUBJECT:
DIABLO CANYON POWER PLANT - NOTIFICATION OF INSPECTION (NRC
INSPECTION REPORT 05000275/2019002, 05000323/2019002 AND
REQUEST FOR INFORMATION
Dear Mr. Welsch:
From April 8 to April 12, 2019, two inspectors from the U.S. 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. 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 team has 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 Ms. Amanda Sorenson 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 the lead inspector Nicholas Hernandez (832) 689-9928
(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.
In accordance with 10 CFR 2.390 of the NRCs "Agency Rules of Practice & Procedure," a copy
of this letter and its enclosure will be available electronically for public inspection in the NRC
Public Document Room or from the Publicly Available Records (PARS) component of NRCs
document system (ADAMS). ADAMS is accessible from the NRC web site at
http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).
