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.
INSPECTION SCOPES
Inspections were conducted using the appropriate portions of the inspection procedures (IPs)in effect at the beginning of the inspection unless otherwise noted. Currently approved IPs with their attached revision histories are located on the public website at http://www.nrc.gov/
reading-rm/doc-collections/insp-manual/inspection-procedure/index.html. Samples were declared complete when the IP requirements most appropriate to the inspection activity were met consistent with Inspection Manual Chapter (IMC) 2515, Light-Water Reactor Inspection Program - Operations Phase. The inspectors performed plant status activities described in IMC 2515, Appendix D, Plant Status and conducted routine reviews using IP 71152, Problem Identification and Resolution. The inspectors reviewed selected procedures and records, observed activities, and interviewed personnel to assess licensee performance and compliance with Commission rules and regulations, license conditions, site procedures, and standards.
