- NOTIFICATION OF INSPECTION (NRC INSPECTION REPORT

0 50002 75/2019002, 05000323/2019002

AND REQUEST FOR INFORMATION

Dear Mr. Welsch: From April 8 to April 12 , 2019 , two inspectors

from the U.S. Nuclear Regulatory Commission's

(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 inspector s 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 (Sectio

n A of the enclosure) identifies

information to be provided prior to the

inspection to ensure that the inspector s are adequately prepared. The second group (Section

B of the enclosure) identifies the information the inspector

s 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

M s. 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

J. Welsch 2 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 NRC's "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 NRC's document system

(ADAMS). ADAMS is accessible from the NRC web site at http://www.nrc.gov/reading

Electronic Reading Room).
