SUMMARY

The U.S. Nuclear Regulatory Commission (NRC) continued monitoring the licensees performance by conducting an integrated inspection at Davis-Besse Nuclear Power Station, 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.

List of Findings and Violations

No findings or violations of more than minor significance were identified.

Additional Tracking Items

None.

PLANT STATUS

The plant began the inspection period at rated thermal power. On January 16, 2020, the plant started coasting down with periodic power reductions. The licensee shut down the plant for the refueling outage on February 29, 2020. The plant remained shut down for 25 days. On March 24, 2020, the licensee started up the plant, but operators tripped the plant at very low power on March 25, 2020, due to a failed transformer fuse. The licensee restarted the plant on March 26, 2020, and the plant reached rated thermal power on March 30, 2020. The plant remained at or near full power for the rest of the inspection period.

On February 27, 2020, the licensees parent company successfully completed its Chapter 11 restructuring process and emerged from bankruptcy as Energy Harbor Nuclear Corp. The NRC Region III inspectors used flexibility in the baseline inspection program to assess the potential impact of the financial conditions on licensee performance. Through February 27, 2020, the inspectors applied additional focus to the following areas:

(1) impact on regulatory required plant staffing,

(2) corrective maintenance backlog,

(3) changes to the planned maintenance schedule,

(4) corrective action program implementation, and

(5) reduction in outage scope, including risk-significant modifications. No concerns were identified.

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/readingrm/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. From January 1 - March 19, 2020, 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.

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 IMC 2515, Appendix D; and observed risk significant activities when warranted. In addition, resident and regional baseline inspections were evaluated to determine if all or portion 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 the cases where it was determined the objectives and requirements could not be performed remotely, management elected to postpone and reschedule the inspection to a later date.

INSPECTION RESULTS

Observation: Trend of Work Planning and Work Management issues 71152 The inspectors reviewed the licensees corrective action program for potential adverse trends in work planning and work management that might be indicative of a more significant safety issue. During the review period for this inspection sample, the inspectors noted that a significant number of low-level performance issues and errors had challenged the licensee.

The inspectors determined that though some of these issues were directly attributable to human performance and/or procedural compliance, there were several that could be attributed to work planning and work management deficiencies. Specific examples associated with this trend included, but were not limited to:

• During the third quarter of 2019, the licensee commenced work to replace the control room emergency air temperature control system train 2 compressor. The plant risk due to the work was modeled as green but when maintenance personnel went out into the field, they identified the lift path for the train 2 compressor required lifting it over the train 1 equipment.

The personnel correctly identified that this situation significantly increased the nuclear safety and generation risk (to yellow) and stopped work. The inspectors noted that the work planning process could have identified this issue prior to work starting. (CR 2019-06415)

• While performing a field walkdown for motor driven feedwater pump target rock cable replacement, the licensee recognized that the conduit intended for use had other safety-related cables running through it that had not been identified during preparation of the engineering change package and work order. The licensee halted the work and developed an alternate approach. The inspectors determined that if this condition had not been recognized and work had proceeded as originally planned, the risk could have been higher than expected. Additionally, the inspectors noted this issue could have been identified during the engineering change process or the work planning process. (CR 2019-06418)

• During a post maintenance run of the emergency feedwater pump, the work order mistakenly directed operators to run the emergency feedwater pump with valves aligned for steam generator injection and not recirculation as intended. The error resulted in an unintended emergency feedwater pump injection into Steam Generator 1 (SG1) for one minute and seventeen seconds. The inspectors noted this event could have been avoided at multiple points during the work planning process and execution of the work order. The inspectors documented this issue in inspection report 2019004 (section 71152).

(CR 2019-07705)

• During a scheduled functional test of the train 2 containment normal range radiation monitor (RE4597BA), the operator performing the test was provided the procedure written for the train 1 containment normal range radiation monitor (RE4597AA). The operator followed the procedure he was given and initiated work on the wrong train component rendering both trains inoperable. The inspectors documented this issue in inspection report 2019002 (section 71152). (CR 2019-03346)

Individually, none of these examples may suggest an ongoing problem but when viewed in the aggregate, the inspectors determined they may indicate a programmatic weakness.

Specifically, for these and other work planning deficiencies the station may be missing the opportunity to identify and resolve deficiencies prior to the work being started, potentially resulting in an adverse impact to the plant. The inspectors provided these observations to the licensee and the licensee agreed that additional focus may be necessary to evaluate the trend. The NRC inspectors plan to continue monitoring the licensees actions to address work planning and work management issues.
