PLANT STATUS

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

On May 11, 2020, Unit 1 reduced power to 55 percent to clean water boxes and condensers. Unit 1 returned to full power on May 17, 2020.

On June 13, 2020, Unit 2 reduced power to 99 percent due to a group rod misalignment. Unit 2 returned to full power on June 30, 2020.

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 2515, Light-Water Reactor Inspection Program -

Operations Phase. 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.

Starting on March 20, 2020, in response to the National Emergency declared by the President of the United States on the public health risks of the coronavirus (COVID-19), resident inspectors were directed to begin telework and to remotely access licensee information using available technology. During this time the resident inspectors performed periodic site visits each week and during that time conducted plant status activities as described in Inspection Manual Chapter 2515, Appendix D; observed risk significant activities; and completed onsite portions of IPs. In addition, resident and regional baseline inspections were evaluated to determine if all or portions of the objectives and requirements stated in the IP could be performed remotely. If the inspections could be performed remotely, they were conducted per the applicable IP. In some cases, portions of an IP were completed remotely and on site. The inspections documented below met the objectives and requirements for completion of the IP.

The inspectors reviewed the licensees implementation of its corrective action program related to the following issues:

(1) The inspectors evaluated a change made to the surveillance frequency of STP M-21C, Main Turbine Valve Testing, in accordance with ECG

OTHER ACTIVITIES

- TEMPORARY INSTRUCTION, INFREQUENT, AND ABNORMAL Evaluation of Diablo Canyon Power Plant Safety Condition in Light of Financial Conditions Because Pacific Gas and Electric Corporation, and its subsidiary, Pacific Gas and Electric Company (the licensee), was under bankruptcy protection/reorganization during the inspection period, NRC Region IV conducted special reviews of processes at Diablo Canyon Power Plant.

Using the flexibilities in the baseline inspection program, the inspectors evaluated several aspects of the licensees operations to determine whether the financial condition of the licensee impacted plant safety. The factors reviewed during this period included:

(1) impact on staffing,

(2) corrective maintenance backlog,

(3) changes to the planned maintenance schedule,

(4) corrective action program implementation, and

(5) any reduction in outage scope, including risk-significant modifications. Considering the licensees financial difficulties, the inspectors verified that licensee personnel continued to identify problems at an appropriate threshold and enter these problems into the corrective action program for resolution. The inspectors also verified that the licensee continued to develop and implement corrective actions commensurate with the significance of the problems identified.

The special review of processes at Diablo Canyon Power Plant included continuous reviews by the resident inspectors, as well as the specialist-led baseline inspections completed during the inspection period which are documented in this report. During this period, the inspectors did not identify any indications that the licensees financial circumstances were adversely affecting plant performance and safety.

INSPECTION RESULTS

Unresolved Item Failure to Replace Early Warning System Batteries at 71114.02 (Closed) Periodicity Required by the Alert and Notification System Design Report URI 05000275,05000323/2019004-02

Description:

During an inspection conducted October 21-24, 2019, the inspectors identified a deviation between the licensees maintenance program for outdoor emergency warning sirens and the licensees commitments as described in their FEMA approved Alert and Notification System (ANS) design report. Therefore, inspectors documented the apparent deviation between emergency warning siren maintenance practices and maintenance commitments in Unresolved Item 05000275,05000323/2019004-02 (ML20023B809). On February 20, 2020, the NRC requested a review by FEMA to establish whether the licensee was in compliance with ANS requirements (ML20042E957).

Response was provided by FEMA on April 2, 2020 (ML20121A265). FEMA indicated that the licensees 5-year battery-replacement interval was inconsistent with the approved ANS design report. The issue was acknowledged as a deviation from the design report. However, information available to them provided by the battery manufacturer supports the change in battery replacement periodicity. Based on this, the deviation does not meet the definition of a significant change as defined in 44 CFR 350.14(b). FEMA recommended that the licensee provide an addendum to the design report addressing the battery replacement interval change.

Based on FEMAs input, the inspectors concluded that the practice of changing the emergency warning system siren batteries at 5-year intervals was not in compliance with the approved ANS design report. However, since the deviation did not meet FEMAs determination criteria of constituting a significant change, it is considered a minor performance deficiency. The issue is being addressed by the licensee in the corrective action program.

Corrective Action Reference: Notification 51052363 Minor Violation 71152 Minor Violation: On March 26, 2020, the licensee made a change to surveillance frequency requirement SR 0.2 of the applicability section of the ECG. This change allowed any surveillance frequency required by the ECG to be extended up to two times its specified interval if a risk analysis is completed and plant senior management approval is obtained.

The inspectors evaluated a change made to the surveillance frequency of STP M-21C, Main Turbine Valve Testing, in accordance with the new ECG SR 0.2 requirements. The inspectors determined that while the change made to the STP M-21C frequency as well as the corresponding risk analysis were appropriate and in accordance with applicable station procedures, the method in which the ECG 0.2 generic surveillance statement itself was changed was inappropriately conducted by the licensee. Specifically, the licensee incorrectly determined that the 10 CFR 50.59 change process did not apply because the change to the generic ECG SR 0.2 applicability was a maintenance activity and therefore covered under the requirements of 10 CFR 50.65(a)(4); therefore, a screen to determine if a more detailed evaluation or NRC prior approval was required was not conducted.

Screening: The inspectors determined the performance deficiency was minor. The failure to appropriately screen the ECG 0.2 change in accordance with 10 CFR 50.59(d)(1) was determined to be a performance deficiency within the licensees ability to foresee and correct. The performance deficiency was determined to be minor in accordance with Inspection Manual Chapter 0612, Appendix B, since it did not adversely impact a cornerstone objective. Specifically, it was determined after appropriate 50.59 screening, that the change to ECG 0.2 did not require NRC prior approval.

Enforcement:

This failure to comply with 10 CFR 50.59 (d)(1) constitutes a minor violation that is not subject to enforcement action in accordance with the NRCs Enforcement Policy.

EXIT MEETINGS AND DEBRIEFS
