EVALUATIONS OF CHANGES, TESTS, AND EXPERIMENTS INSPECTION

(NRC INSPECTION REPORT 05000275/2020001 AND 05000323/2020001)

AND REQUEST FOR INFORMATION

Dear Mr. Welsch:

The purpose of this letter is to notify you that U.S. Nuclear Regulatory Commission (NRC) staff

will conduct the baseline inspection of evaluations of changes, tests, and experiments at your

Diablo Canyon Power Plant, Units 1 and 2, from March 9-13, 2020. The inspection will consist

of three reactor inspectors from the NRCs Region IV office for one week. The inspection will be

conducted in accordance with NRC Inspection Procedure (IP) 71111.17T, Evaluations of

Changes, Tests, and Experiments.

Experience has shown that this inspection is resource intensive for both 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.

Please note that the documents are requested to be provided by February 18, 2020. 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 licensing

organization. If there are any questions about this inspection or the material requested, please

contact the lead inspector, Ron Kopriva, by telephone at 817-200-1104 or by e-mail at

Ron.Kopriva@nrc.gov.
