SUMMARY

The U.S. Nuclear Regulatory Commission (NRC) continued monitoring the licensees performance by conducting an integrated inspection at Diablo Canyon Power Plant, Units 1 and 2, in accordance with the Reactor Oversight Process. The Reactor Oversight Process is the NRCs program for overseeing the safe operation of commercial nuclear power reactors.

Refer to https://www.nrc.gov/reactors/operating/oversight.html for more information. NRC-identified and self-revealed findings, violations, and additional items are summarized in the table below. Licensee-identified non-cited violations are documented in the Inspection Results at the end of this report.

List of Findings and Violations No findings or violations of more than minor significance were identified during the inspection.

PLANT STATUS

Units 1 and 2 began the inspection period at full power.

On November 28, 2018, Unit 1 reduced power to 50 percent to clean water boxes and condensers and to troubleshoot high vibrations on main feedwater pump 1-1. Unit 1 returned to full power on December 5, 2018.

On December 1, 2018, Unit 2 tripped from full power due to a full load reject. Unit 2 returned to full power on December 3, 2018.

On December 18, 2018, Unit 2 reduced power to 50 percent to clean water boxes and condensers. Unit 2 returned to full power on December 20, 2018.

Units 1 and 2 operated at full power for the remainder of the inspection period.
