November 9, 2018 Mr. James M. Welsch Vice President, Nuclear Generation and Chief Nuclear Officer Pacific Gas and Electric Company P.O. Box 56 Mail Code 104/6 Avila Beach, CA 93424

SUBJECT:

CLOSURE OF INVESTIGATION (OI 4-2017-039)

Dear Mr. Welsch:

This refers to an investigation conducted by the U.S. Nuclear Regulatory Commissions (NRCs)

Office of Investigations regarding activities at Diablo Canyon Power Plant. The Office of Investigations initiated the investigation to determine whether personnel willfully failed to report aberrant behavior to Diablo Canyon Power Plant access officials as required by the behavior observation program.

Based on the evidence developed during the investigation, the concern that personnel willfully failed to report aberrant behavior to Diablo Canyon Power Plant access officials as required by the behavior observation program was not substantiated. The NRC plans no further action related to the alleged wrongdoing and considers this investigation closed.

You should note that final NRC documents may be made available to the public under the Freedom of Information Act subject to redaction of information pursuant to the Freedom of Information Act. Requests under the Freedom of Information Act should be made in accordance with 10 CFR 9.23, Requests for Records. Information is accessible from the NRCs website at http://www.nrc.gov/reading-rm/foia/foia-request.html#how.

In accordance with 10 CFR 2.390 of the NRCs Agency Rules of Practice and Procedure, a copy of this letter will be made available electronically for public inspection in the NRC Public Document Room or from the NRC's Agencywide Documents Access and Management System (ADAMS), accessible from the NRC website at http://www.nrc.gov/reading-rm/adams.html.

Sincerely,

/RA/
