PLANT STATUS

The plant began the inspection period at or near 58 percent rated thermal power in preparation for a planned refueling outage. On February 4, 2022, during a planned power reduction to start the refueling outage, the plant experienced a perturbation in the feedwater system which resulted in a reactor scram. Following stabilization after the scram, the plant commenced a cooldown to commence outage activities. Fermi remained shut down for the remainder of the inspection period due to the RF21 outage.

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 activities described in IMC 2515, Appendix D, Plant Status, conducted routine reviews using IP 71152, Problem Identification and Resolution, observed risk significant activities, and completed on-site portions of IPs. 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.

INSPECTION RESULTS

Failure to Establish Periodic Inspection and Maintenance of the Alternate Diesel Fire Pump Engine Fuel-Water Separator Cornerstone Significance Cross-Cutting Aspect Report Section Mitigating Systems Green NCV 05000341/2022001-01 Open/Closed

[H.4] -

Teamwork 71111.12 A self-revealed Green finding and associated NCV was identified when the licensee failed to establish periodic inspection, maintenance, and testing procedures for the alternate diesel fire pump (ADFP) in accordance with MES35, Fire Protection. Specifically, the licensee did not establish a procedure to routinely check the water level of the ADFP engine fuel water separator and drain water when needed to ensure continued functionality of the ADFP.

Description:

On February 7, 2021, an ADFP was installed via temporary modification (TM)21-0001 due to an equipment problem with the permanently installed diesel fire pump. The ADFP was in an outdoor environment with the normally water filled portions of the system (i.e., pump and associated piping) inside a temporary enclosure that was heated in the winter.

The ADFP engine and associated fuel supply were not enclosed by design and were subject to outdoor environmental conditions.

On January 7, 2022, the ADFP was removed from service for planned seasonal (cold weather) maintenance. Planned maintenance activities included replacement of the engine fuel system primary filter (i.e., fuel water separator). Upon removal of the ADFP engine fuel water separator, the filter element itself was found half-dry with a large piece of ice present at the bottom of the fuel water separator bowl. The licensee replaced the fuel water separator, primed the fuel system, and attempted to start the ADFP to inspect the fuel system for leaks.

The ADFP subsequently failed to start on January 7, 2022. Troubleshooting identified ice buildup in the fuel lines as the most likely cause. The ADFP was returned to service on January 14, 2022, which was within the allowable 14-day Technical Requirements Manual 3.12.2 required action completion time. The ADFP had started, and ran successfully during the previous weekly operability test on January 3, 2022.

Licensee procedure MES35, Fire Protection, required the fire protection program to consist of periodic inspection, maintenance, and testing of fire detection and protection systems.

TM 21-0001 included the manufacturer operation and maintenance manual (TM 21-0001.016), which included instructions for maintaining the fuel water separator. Too much water in the fuel water separator can lead to engine performance problems regardless of environmental conditions (e.g., summer or winter). However, the licensee periodic inspection, maintenance, and testing procedures did not contain provisions to routinely monitor for, or drain water if present from the ADFP engine fuel water separator as recommended by the manufacturer operation and maintenance manual.

Corrective Actions: The licensee revised procedure 28.504.02, Diesel Fire Pump Engine Weekly Operability Test, to include an inspection of the ADFP fuel water separator water level. The revised procedure specified to write a CARD if the ADFP fuel water separator water level was greater than 25 percent to allow draining of the water, and to declare the ADFP non-functional if the water level was greater than 50 percent water (regardless of environmental conditions).

Corrective Action References: CARD 22-20233

Performance Assessment:

Performance Deficiency: The licensee's failure to establish periodic inspection, maintenance, and testing procedures for the ADFP was not in accordance with procedure MES35, Fire Protection, and was a performance deficiency. Specifically, the licensee did not establish a procedure to routinely check the water level of the ADFP engine fuel water separator and drain water when needed to ensure continued functionality of the ADFP.

Screening: The inspectors determined the performance deficiency was more than minor because it was associated with the Equipment Performance attribute of the Mitigating Systems cornerstone and adversely affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, the failure to establish periodic inspection, maintenance, and testing procedures for the ADFP resulted in enough water accumulation in the ADFP engine fuel water separator to render the ADFP non-functional.

Significance: The inspectors assessed the significance of the finding using Appendix F, Fire Protection and Post - Fire Safe Shutdown SDP. In accordance with Step 1.4.3, Fire Water Supply, the inspectors determined that the finding was of very low safety significance (Green). Specifically, the electric fire pump was available to provide adequate fire water capacity for protection of equipment important to safe shutdown in the most limiting location onsite for the duration that the ADFP was non-functional.

Cross-Cutting Aspect: H.4 - Teamwork: Individuals and work groups communicate and coordinate their activities within and across organizational boundaries to ensure nuclear safety is maintained. Specifically, work groups did not communicate and coordinate during the ADFP modification review to ensure it was informed about the maintenance provisions included in the ADFP manufacturer operation and maintenance manual.

Enforcement:

Violation: Technical Specification 5.4.1.d requires written procedures to be established, implemented, and maintained covering fire protection program implementation. The licensee established MES35, Fire Protection, Revisions 12 and 13, as a fire protection program implementation procedure.

Contrary to the above, from February 7, 2021, to January 13, 2022, the licensee failed to implement a written procedure covering fire protection program implementation.

Specifically, the licensee did not implement procedure MES35, step 3.3.7. This step required, in part, periodic inspection and maintenance of fire protection systems. However, the licensee did not establish periodic inspection and maintenance to check the water level of the ADFP engine fuel water separator and drain water when necessary. As a result, on January 7, 2022, the ADFP was declared non-functional due to water in the ADFP engine fuel system.

Enforcement Action: This violation is being treated as a non-cited violation, consistent with Section 2.3.2 of the Enforcement Policy.

Failure to Identify an Adverse Containment Isolation Valve Stroke Time Cornerstone Significance Cross-Cutting Aspect Report Section Barrier Integrity Green NCV 05000341/2022001-02 Open/Closed

[H.12] - Avoid Complacency 71111.15 A Green finding and an associated violation of 10 CFR 50, Appendix B, Criterion XVI, "Corrective Actions," was self-revealed when the drywell equipment drain sump outboard containment isolation valve G1100F019 failed its Inservice Testing (IST) stoke time test on January 2, 2022. Specifically, the licensee discovered the valve had a slow close stroke time.

Consequently, they increased the valve testing frequency with the intent of promptly identifying and correcting an adverse closed stroke time. However, the licensee failed to stroke time test the valve in accordance with the increased frequency in November and December 2021.

Description:

On April 2, 2021, during performance of Inservice Testing (IST) Surveillance 24.702.01, Miscellaneous Systems Valve Operability Test, the licensee discovered that the drywell equipment drain sump outboard containment isolation valve G1100F019 and drywell floor drain sump outboard containment isolation valve G1100F003 closing stroke time fell outside the IST limit of 34.0 seconds, and owner specified limit of 36.8 seconds. Specifically, the stroke times of G1100F019 and G1100F003 were 42.5 and 52.7 seconds, respectively.

Both valves were air-operated containment isolation valves (AOVs). Per Fermi Technical Requirement Manual Section 3.6, the maximum isolation times for these two automatic containment isolation valves were 60 seconds.

The licensee entered this issue into their corrective action program as CARD 21-22976. Per the 2012 Edition of the American Society of Mechanical Engineer (ASME) Operation and Maintenance (OM) Code, the licensee immediately declared the valves as inoperable, retested them, and performed an analysis to show that the valves were working correctly per subsequent stroke time measurements. The licensee determined that both valves were degraded but functional and the potential causes for the long stroke time likely were debris-related binding at the seat, or a sticking solenoid. The licensee placed both valves on an increase testing frequency (monthly) to ensure potential adverse closed stroke time trend was promptly identified and corrected.

On May 9, 2021, during performance of the increased frequency stroke time test for valve G1100F003, the licensee identified that the close stroke time was 1,020 seconds. The licensee immediately declared the valve inoperable and determined that the AOV solenoid was sticking. The licensee replaced the solenoid and established a new periodic replacement frequency for the solenoid. Since the replacement of the solenoid in May 2021, stroke time testing of valve G1100F003 has shown no degradation in the closing stroke time.

The licensee determined valve G1100F019 needed to remain on increased testing frequency until the refueling outage scheduled to start in February 2022 based on their review of stroke times. Specifically, the close stroke time of valve G1100F019 were 30.8, 29.7, 28.8, 30.3, 28.5 and 33.6 seconds in May, June, July, August, September, and October of 2021, respectively. The licensee added a work order to replace the solenoid associated with valve G1100F019 in the 2022 refueling outage. However, the licensee did not monitor the valve condition by failing to perform the increased frequency stroke time test in November and December 2021. On January 2, 2022, the licensee performed the normal quarterly IST surveillance (i.e., procedure 24.702.01) and observed the stroke time of the valve to be 61.4seconds. The licensee immediately declared the valve to be inoperable, retested the valve, and performed an analysis to show that the valve was working correctly per subsequent stroke time measurements. Subsequently, the licensee concluded that valve G1100F019 was unable to perform its design function to close between the time the surveillance performed on October 1, 2021, and the surveillance performed on January 2, 2022.

Corrective Actions: At the time of this inspection period, the licensee planned to replace the solenoid during the 2022 refueling outage. The licensee also initiated an action to create a process change for scheduling and performing partial surveillance.

Corrective Action References: CARD 22-20008

Performance Assessment:

Performance Deficiency: The inspectors determined that the failure to promptly identify the G1100F019 stroke time exceeded IST and TRM limits was contrary to 10 CFR 50, Appendix B, Criterion XVI, Corrective Action, and was a performance deficiency.

Screening: The inspectors determined the performance deficiency was more than minor because it was associated with the SSC and Barrier Performance attribute of the Barrier Integrity cornerstone, and adversely affected the cornerstone objective to provide reasonable assurance that physical design barriers protect the public from radionuclide releases caused by accidents or events. Specifically, the valve with a degraded stroke time was not monitored and eventually the stroke time exceeded the containment isolation timing assumed in the safety analysis.

Significance: The inspectors assessed the significance of the finding using Appendix A, The Significance Determination Process (SDP) for Findings At-Power. Since this finding does not represent an actual open pathway in the physical integrity of the containment and it does not involve the function of the hydrogen igniters, this finding was of very low safety significance (Green).

Cross-Cutting Aspect: H.12 - Avoid Complacency: Individuals recognize and plan for the possibility of mistakes, latent issues, and inherent risk, even while expecting successful outcomes. Individuals implement appropriate error reduction tools. Specifically, the licensee did not verify that all the required surveillances needed for the increased test frequency were scheduled.

Enforcement:

Violation: Title 10 CFR 50, Appendix B, Criterion XVI, Corrective Action, requires, in part, that measures shall be established to assure that conditions adverse to quality, such as non-conformances, are promptly identified and corrected.

Contrary to the above, from November 1, 2021, to January 2, 2022, the licensee failed to promptly identify a condition adverse to quality. Specifically, the licensee discovered the drywell equipment drain sump outboard containment isolation valve G1100F019 had a degrading close stroke time. Consequently, they increased the valve testing frequency from quarterly to monthly, with the intent of promptly identifying and correcting an adverse closed stroke time. However, the licensee failed to stroke time test the valve in accordance with the increased frequency in November and December 2021. On January 2, 2022, a normal quarterly IST surveillance revealed the stroke time exceeded the IST and TRM stroke time limits.

Enforcement Action: This violation is being treated as a non-cited violation, consistent with Section 2.3.2 of the Enforcement Policy.
