PLANT STATUS

Unit 1 began the inspection period at rated thermal power. On October 9, 2020, the unit was downpowered to approximately 70 percent to perform a control rod pattern adjustment. The unit was returned to rated thermal power on October 10, 2020. On November 29, 2020, the unit was downpowered to approximately 72 percent to perform a control rod pattern adjustment and remove the 15 recirculation motor generator set from service for maintenance. The unit was returned to rated thermal power on November 30, 2020. On December 18, 2020, the unit was downpowered to approximately 70 percent to perform a control rod pattern adjustment and restore the 15 recirculation motor generator set to service. The unit was returned to rated thermal power on December 19, 2020 and remained at or near rated thermal power for the remainder of the inspection period.

Unit 2 began the inspection period at rated thermal power. On October 23, 2020, the unit was downpowered to approximately 75 percent to perform a control rod pattern adjustment and control rod scram timing. The unit was returned to rated thermal power on October 24, 2020 and remained at or near rated thermal 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 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; observed risk significant activities; and completed on site 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.

INSPECTION RESULTS

Observation: Review of Corrective Actions on Direct Current Motor-Operated 71152 Valve Copper-Clad Steel Brush Holders The inspectors reviewed Exelons evaluation and corrective actions following the identification of an issue with the copper-clad steel brush holders in the motors of direct current (DC)motor-operated valves (MOVs). In April 2017, a safety-related isolation MOV in the Unit 1 emergency condenser system, IV-39-08R, failed in mid-position during a surveillance test. Exelon generated issue report (IR) 03993689 to document the failure. The station conducted a causal evaluation and concluded that corrosion buildup from the DC MOV steel brush holder led to inadequate electrical contact between the brushes and commutator.

Corrosion from the brush holders can prevent the brushes from sliding freely to maintain contact with the commutator. Issue Report 03993689 stated that a new DC motor was installed in April 2015 and the brush holder had corroded in only two years of normal service life. Exelon identified a list of safety-related MOVs susceptible to the same condition.

Additionally, in October 2019, DC MOV IV-39-08R failed in its mid-position due to a different issue. Exelon generated IR 04292465 to address the issue and included corrective actions to address the deficient copper-clad steel brush holders.

As actions within IR 04282465, Exelon generated a list of 17 DC MOVs and associated work orders to inspect the brush holders using S-EPM-GEN-067, Limitorque MOV Actuator P.M.,

Revision 01100, within two years or next outage (Unit 2 refueling outage in 2022 was the latest date, due to replacement part lead time). As stated in the IR, brass brush holders and spare DC motors shall be available to replace the current steel brush holders and motors (as a contingency). In accordance with S-EPM-GEN-067, if operators identify signs of cracking, pitting, or corrosion in the brush holder area, the brush holders or motor is to be replaced with solid brass brush holders.

The inspectors reviewed Exelons corrective actions at Unit 1 and Unit 2 associated with deficient steel brush holders contained within IRs 03993689 and 04292465. The inspectors reviewed the extent of condition list of DC MOVs to ensure all potentially affected MOVs had been identified, and reviewed the status of Exelons actions, including a review of work order status. The inspectors also reviewed Exelons readiness with replacement parts, or the ability to procure them, if they are needed.

As a result of the inspectors' review, Exelon generated IR 04388354 to document improvements that can be made to scheduling work activities and to revise the Unit 1 refuel outage work schedule.

Observation: Semi-Annual Trend Review 71152 The inspectors identified a trend associated with degraded conditions which have existed for a long period of time and impact plant operations. Following the identification of the individual issues, Exelon generated IRs in their corrective actions program to address the issues and define corrective actions. However, the inspectors identified that multiple issues that require additional actions by operators have existed for an extended period of time due to delayed corrective actions.

Specifically, the inspectors identified outstanding issues on a number of systems, the most significant of which are the Unit 1 mechanical hydraulic control (MHC) system identified in IRs 02485219 and 04244521; the Unit 1 fire protection system identified in IRs 04347881 and 04385984; and the Unit 2 service water system identified in IRs 02535772 and 04277608.

The issue on the MHC system is discussed in the Inspection Results Section of Inspection Report 05000220/2019010 and 05000410/2019010. The issue on the fire protection system was reviewed during this inspection period, as documented in section 71111.15. The issue on the service water system is discussed in the Inspection Results Section of Inspection Report 05000220/2020003 and 05000410/2020003.

In each of the above referenced issues, additional actions are/were required by operators to operate the plant or respond to events. The corrective actions for these conditions have been extended for various reasons. Specifically, the Unit 1 MHC system issue (power instability region due to inadequate lead-lag testing) was initially scheduled with a due date of November 8, 2019 and is now delayed to the Spring 2021 refueling outage. The Unit 2 service water issue (valve 2SWP*MOV21B failed in mid-position) has existed since September 9, 2020 and has been extended to the Spring 2022 refueling outage. The Unit 1 local fire panel issues (e.g. fire damper failed to open, leading to trouble alarms on a local fire panel) have existed since at least May 28, 2020.

As a result of these outstanding degraded conditions, Unit 1 has an Operator Burden to address pressure oscillations due to the MHC issue, Unit 1 has had nuisance alarms affecting operators ability to interface with the local fire panels due to the fire protection system issues, and Unit 2 has revised an Abnormal Operating Procedure to include opening an additional valve due to the service water valve issue.

The examples above demonstrate a trend. The inspectors determined the trend is not an additional performance deficiency.
