List of Findings and Violations

Failure to Establish Fire Compensatory Measure During Maintenance Activities Cornerstone Significance Cross-Cutting Report Aspect Section Mitigating Green [P.3] - 71111.05 Systems NCV 05000482/2022001-01 Resolution Open/Closed The inspectors identified a Green finding and associated non-cited violation of Technical Specification 5.4.1.d, for the licensees failure to implement the fire protection program procedure requirements. Specifically, the licensee failed to implement appropriate fire compensatory measures during planned maintenance activities that prevented a fire and halon boundary door from self-closing and latching due to ventilation airflow.

Failure to Correct Inadequate Procedural Guidance Cornerstone Significance Cross-Cutting Report Aspect Section Mitigating Green [P.5] - 71111.12 Systems NCV 05000482/2022001-02 Operating Open/Closed Experience The inspectors reviewed a self-revealed Green finding and associated non-cited violation of Technical Specification 5.4.1.a, for the licensees failure to properly pre-plan and perform maintenance that can affect the performance of safety-related equipment. Specifically, the licensee failed to correct inadequate procedural guidance associated with filling and venting the emergency diesel generator jacket water and intercooler system following planned maintenance. This condition resulted in air binding the emergency diesel generator A jacket water keep warm pump, resulting in jacket water leakage greater than allowed to support emergency diesel generator operability.

Failure to Schedule Preventive Maintenance to Prevent Unacceptable Preconditioning Cornerstone Significance Cross-Cutting Report Aspect Section Mitigating Green None (NPP) 71111.22 Systems NCV 05000482/2022001-03 Open/Closed The inspectors identified a Green finding and associated non-cited violation of Title 10 of the Code of Federal Regulations, Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, for the licensee failure to accomplish instructions, procedures, or drawings appropriate to the circumstances that would have prevented unacceptable preconditioning of the 125 Vdc battery chargers. Specifically, the licensee failed to accomplish Procedure AI 29B-003, Guidance to Prevent Unacceptable Preconditioning Prior to Testing,

Revision 2, to not schedule preventive maintenance prior to conducting as-found 125 Vdc battery charger technical specification surveillance testing. This resulted in three examples of unacceptable preconditioning the 125 Vdc battery chargers.

Additional Tracking Items

None.

PLANT STATUS

Wolf Creek Generating Station began the inspection period at full power. On February 11, 2022, the licensee reduced power to 62 percent at the request of the transmission system operator to facilitate unplanned outage of the 345 kV Benton Line and was returned to full power on February 12, 2022. On March 24, 2022, the licensee reduced power to 62 percent at the request of transmission system operator to facilitate planned maintenance outage of the 345 kV Rose Hill line and was returned to full power on March 25, 2022. On three occasions during the quarter the licensee reduced power to 70 percent for flexible power operations (based on daily market demand) and returned to full power after each occasion.

OTHER ACTIVITIES

- TEMPORARY INSTRUCTIONS, INFREQUENT AND ABNORMAL

===60855 - Operation of an ISFSI

The inspectors performed a review of the licensees Independent Spent Fuel Storage Installation (ISFSI) activities to verify compliance with requirements of the Transnuclear (TN)

Nutec Horizontal Modular Extended Optimized Storage (NUHOMS EOS) system's Certificate of Compliance 72-1042, Amendment 1, and Final Safety Analysis Report (FSAR), Revision 3. The inspectors reviewed selected procedures, corrective action reports, and records to verify ISFSI operations were compliant with the Certificate's technical specifications, requirements in the FSAR, and NRC regulations.

Operation of an ISFSI===

(1) The inspectors evaluated the licensees dry cask storage operations, from January 17-21, 2022, during an onsite inspection. The ISFSI is located within the Part 50 reactor's protected area. The EOS Matrix ISFSI pad was designed to hold 64 dry shielded canisters (DSCs), each with 37 spent fuel assemblies. The EOS Matrix design contains two levels of HSM-MXs (horizontal storage module-matrix). Currently the licensee had constructed 11 HSM-MXs, each capable of receiving one DSC, on the southeast portion of the ISFSI pad. During the first loading campaign Wolf Creek Generating Station planned on loading five DSCs into the lower level of the EOS Matrix. Inspectors observed loading activities associated with the first DSC loaded to the ISFSI.

During the onsite inspection, the inspectors evaluated and observed the following activities:

Fuel selection and spent fuel placement into the DSC Removal of the loaded DSC from the spent fuel pool to the canister processing area Welding and non-destructive testing of the lid-to-shell welds of the DSC Canister vacuum drying and pneumatic testing of the DSC Welding, non-destructive testing, and helium leak testing of the top plate and vent/drain port covers Lifting and down-ending transfer cask/DSC from the processing area to the heavy haul transport trailer Transport from the spent fuel building to the ISFSI pad using the heavy haul transport trailer Use of the matrix loading crane to insert the DSC from the transfer cask to a lower level HSM-MX storage module.

===60856 - Review of 10 CFR 72.212(b) Evaluations

The inspection was conducted to determine if Wolf Creek Generating Station met the general license requirements of 10 CFR Part 72 before conducting operations to load their ISFSI.

Review of 10 CFR 72.212(b) Evaluations===

(1) Wolf Creek Generating Station had elected to become a 10 CFR Part 72 general licensee in accordance with 10 CFR 72.210. In previous inspections throughout 2020 and 2021, the licensee had completed all required pre-operational activities required by the Certificate of Compliance and NRC had finished reviewing the majority of the site's programs and evaluations associated with 10 CFR 72.212. During the inspection period (January 1st through January 26, 2022), the inspectors continued the inspection of Wolf Creek's programs, procedures, and calculations performed by the licensee to meet the requirements of 10 CFR Part 72. Specifically, the inspectors completed the review of:

INSPECTION RESULTS

Failure to Establish Fire Compensatory Measure During Maintenance Activities Cornerstone Significance Cross-Cutting Report Aspect Section Mitigating Green [P.3] - 71111.05 Systems NCV 05000482/2022001-01 Resolution Open/Closed The inspectors identified a Green finding and associated non-cited violation of Technical Specification 5.4.1.d, for the licensees failure to implement the fire protection program procedure requirements. Specifically, the licensee failed to implement appropriate fire compensatory measures during planned maintenance activities that prevented a fire and halon boundary door from self-closing and latching due to ventilation airflow.

Description:

On January 18, 2022, the inspectors were performing walkdowns for scheduled train A Class 1E electrical equipment air conditioning system (SGK05A) maintenance activity to verify the licensee implemented their planned risk-management measures. Specifically, the licensee placed the train B Class 1E electrical equipment air conditioning system (SGK05B) in cross-training operation as required by Technical Specification 3.7.20, Class 1E Electrical Equipment Air-Conditioning (A/C) System, in order to use SGK05B to cool the safety-related ac and dc electrical equipment in both trains and was implemented in accordance with Procedure SYS GK-201, Mitigating Actions for Inoperable SGK05 Train, Rev. 3A. During this walkdown, the inspectors identified safety-related dc switchgear room 4 (Room 3404), the active door (Door 34041), was not automatically closing and latching due to the increased differential pressure caused by the infrequent ventilation lineup, and no breach permit authorization for the door, or the required fire compensatory measure were posted in the area. Door 34041 was credited as a fire door and halon system boundary as documented in Procedure WCRE-35, Boundary Matrix, Revision 8, and was required to self-close and latch to meet the halon boundary requirements. Therefore, the licensee was required to initiate a breach authorization permit and a fire compensatory measure of an hourly fire watch for a nonfunctional halon system in accordance with Procedures AP 10-103, Fire Protection Impairment Control, Revision 36, and AP 10-104, Breach Authorization, Revision 39.

Specifically, Procedures AP 10-103 and AP 10-104 required the following:

Procedure AP 10-103, Step 5.6.1, stated, All personnel shall maintain operability/functionality of all required barriers. Note: Fire doors with automatic closers that do not close and latch on their own require a breach authorization permit, which is also required by Procedure SYS GK-201 for any dc electrical switchgear room or battery room doors that do not close and latch automatically and initiate a condition report (CR) and occurs approximately 15 to 20 minutes after establishing the SGK05B cross-training alignment. The inspectors reviewed the previous occurrences of the implementation of Procedure SYS GK-201 and identified two CRs where dc electrical room and battery doors did not automatically close and latch. The doors identified where random and never the same. In response, the licensee developed a corrective action to install a second closure on multiple doors affected by the condition that prevented Door 34041 from automatically closing and latching. However, at the time inspectors identified Door 34041 was not automatically closing and latching, the second closure mechanism was not installed, and the inspectors did not identify an interim corrective action (i.e., establish an hourly fire watch when implementing Procedure SYS GK-201) until the final corrective action was completed.

Procedure AP 10-104, Step 5.5.1, stated, Fire protection [personnel] shall specify the compensatory measure required when a fire barrier is breached, degraded, or determined inoperable/nonfunctional.

Procedure AP 10-103, Attachment E, Required Action C.1, required the establishment of an hourly fire watch for any other halon system nonfunctional.

The inspectors informed the licensee of the condition of Door 34041. The licensee established the required hourly fire watch per barrier permit BAP 22-0015 and initiated CR 10011703.

Corrective Actions: The licensee established the required fire compensatory measure for an inoperable halon boundary door.

Corrective Action References: CR 10011703

Performance Assessment:

Performance Deficiency: The licensees failure to establish fire compensatory measures for a halon boundary door failure to automatically close and latch during air conditioning system SGK05A maintenance activities was a performance deficiency.

Screening: The inspectors determined the performance deficiency was more than minor because it was associated with the Protection Against External Factors 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 of Door 34041 self-closing mechanism to close and latch the door degraded the fire barrier function and prevented the door from retaining a halon release and required a fire compensatory measure of stationing an hourly fire watch for the halon protected safety-related switchgear room 4 during planned train A Class 1E air conditioning system maintenance activity.

Significance: The inspectors assessed the significance of the finding using Appendix F, Fire Protection and Post - Fire Safe Shutdown SDP. The inspectors assigned the finding a fire Category 1.4.1 using Inspection Manual Chapter 0609, Appendix F, Attachment 1, Fire Protection Significance Determination Process Worksheet, dated May 2, 2018, because the finding involved fire prevention and administrative controls. The inspectors determined that the finding had very low safety significance (Green) because the finding:

(1) did not increase the likelihood of a fire, delay detection of a fire, or resulted in a more significant fire than previously analyzed such that credited safe shutdown strategy could be adversely impacted; and

(2) the degraded fire confinement element continued to provide adequate fire endurance to prevent fire propagation through the fire confinement element given the combustible loading and location of equipment important to safe shutdown in the fire area of concern.

Specifically, there was no combustible material or safety equipment that constituted a fire target in the hallway adjoining the degraded door.

Cross-Cutting Aspect: P.3 - Resolution: The organization takes effective corrective actions to address issues in a timely manner commensurate with their safety significance.

Specifically, the licensee failed to establish interim corrective actions to ensure fire compensatory measures were established for inoperable halon boundary doors during air conditioning system SKG05A maintenance activities until the final corrective action was completed.

Enforcement:

Violation: Technical Specification 5.4.1.d requires that written procedures shall be established, implemented, and maintained covering fire protection program implementation.

The licensee established Procedures AP 10-103, Revision 36, and AP 10-104, Revision 39, for impairments of the fire protection system and instructions to maintain required barriers for fire protection.

Procedure AP 10-104, Step 5.5.1, stated, Fire protection [personnel] shall specify the compensatory measure required when a fire barrier is breached, degraded, or determined inoperable/nonfunctional.

Procedure AP 10-103, Attachment E, Required Action C.1, required the establishment of an hourly fire watch patrol for any other halon system nonfunctional.

Contrary to the above, on January 18, 2022, the licensee failed to implement fire protection program Procedures AP 10-104 and AP 10-103 to specify compensatory measures when a fire barrier was degraded and to establish hourly fire watch patrols with a nonfunctional halon system. Specifically, when Door 34041 self-closing mechanism failed to close and latch the door when it was opened with SGK05B in cross-train mode, the fire barrier was degraded but the licensee failed to establish the hourly fire watch patrol for the halon system being nonfunctional.

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

Failure to Correct Inadequate Procedural Guidance Cornerstone Significance Cross-Cutting Report Aspect Section Mitigating Green [P.5] - 71111.12 Systems NCV 05000482/2022001-02 Operating Open/Closed Experience The inspectors reviewed a self-revealed Green finding and associated non-cited violation of Technical Specification 5.4.1.a, for the licensees failure to properly pre-plan and perform maintenance that can affect the performance of safety-related equipment. Specifically, the licensee failed to correct inadequate procedural guidance associated with filling and venting the emergency diesel generator jacket water and intercooler system following planned maintenance. This condition resulted in air binding the emergency diesel generator A jacket water keep warm pump, resulting in jacket water leakage greater than allowed to support emergency diesel generator operability.

Description:

On January 10, 2022, following the performance of emergency diesel generator (EDG) A monthly operability run, a jacket water leak was identified from jacket water keep warm pump PKJ01A at 25 milliliters per minute (mL/min). This leak rate was in excess of the maximum allowed jacket water leak operability limit of 8.6 mL/min to support a 7-day mission time for EDG A. The licensee declared EDG A inoperable, isolated the jacket water leak from pump PKJ01A to restore operability of EDG A, replaced pump PKJ01A and returned it to service, and performed a dynamic vent of the jacket water system in addition to performing the static fill and vent in accordance with Procedure SYS KJ-130, Removal and Restoration of EDG Support Systems, Revision 13. The licensee entered this condition into corrective action program as CR10011538 and performed an equipment performance evaluation.

The inspectors reviewed the equipment performance evaluation documented in CR 10011539, previous corrective actions documented in CR 137247 due to EDG A jacket water low temperature and pressure alarms during a maintenance run, and internal and external EDG operating experience. From these reviews the inspectors noted the following:

CR 10011539: The most probable cause of the jacket water leak from PKJ01A mechanical seal was due to running the pump air bound following maintenance performed in September 2021 in accordance with Work Order 19-4564130-000. This most likely occurred when placing pump PKJ01A and jacket water heaters into service without adequately filling and venting the jacket water system in accordance with Procedure SYS KJ-130. With pump PKJ01A air bound, overheating occurred causing the shaft to slip on the inner race of the pump bearing and damaging the seal surface due to movement. This seal surface damage increased until the jacket water leak occurred on January 10, 2022, causing EDG A to be declared inoperable until the leak was isolated and repaired.

CR 137247: On October 15, 2019, the low jacket water pressure and low temperature alarm was received approximately 10 minutes into the EDG A maintenance run, which resulted in elevated EDG A operating temperatures. Additional venting of EDG A jacket water system resulted in unexpected amounts of air being vented from the system. The licensee determined that the system had likely been air bound, and that the jacket water low pressure was due to air binding of the engine driven jacket water pump. Lastly, the temperature of the jacket water indication showing a stable reading around 115 degrees Fahrenheit was because there was no/flow through the system.

This explained why no temperature alarms were received until after EDG A was secured, which resulted in movement of the air voids, and subsequent change in the temperature readings. The licensee determined the fill and vent guidance contained in Procedure SYS KJ-130 was inadequate, but the licensee only considered it an enhancement due to installing additional high point vents on the EDGs engine driven jacket water and intercooler system.

External Operating Experience: The inspectors identified the following operation experience from May 4, 2020, which was not identified by the licensee and evaluated for similar impacts filling and venting EDG jacket water and intercooler systems following maintenance activities. An EDG at another operating reactor station tripped on low intercooler pressure due to air entrained in the system after maintenance and post-maintenance testing was performed. The EDG system was not fully vented because guidance in the venting procedures lacked instructions to perform a robust dynamic venting following draining of the air coolant and jacket water cooling systems.

The venting procedures used were consistent with current industry standards and written vendor guidance, but not sufficient to address the specific circumstance encountered in this event. The inadequate system venting occurred due to EDG jacket water and air coolant systems containing many small, localized high points.

Also, low temperature coolant has more oxygen entrained in it and will release oxygen into the coolant system when it is heated up during full speed and full operation.

Passive venting of the system can remove most of the air. However, to be effective, a more robust venting process was necessary to dynamically vent at multiple points in the system during heat up and while running loaded to ensure all air was removed and ensure the air coolant cooler did not retain trapped air, it was important to validate the temperature control valve (provides flow through the air coolant cooler) was open when venting.

The inspectors reviewed the above information and determined the licensee failed to use external operating experience to develop corrective actions ensure adequate filling and venting guidance was contained in Procedure SYS KJ-130. Specifically, the licensee did not incorporate the use of dynamic venting when the jacket water and intercooler system was partial drained to ensure all air voids are removed from the system.

Corrective Actions: Incorporated dynamic venting guidance for when the EDG jacket water and intercooler system was partially drained for maintenance activities are contained in Procedure SYS KJ-130.

Performance Assessment:

Performance Deficiency: The licensees failure to correct inadequate procedural guidance associated with filling and venting the EDG jacket water and intercooler system following maintenance was a performance deficiency.

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 adequately fill and vent the EDG jacket water and intercooler system following EDG A jacket water keep warm pump maintenance resulting in air bending the pump and jacket water leakage greater than allowable to maintain EDG operability.

Significance: The inspectors assessed the significance of the finding using Appendix A, The Significance Determination Process (SDP) for Findings At-Power. Using Exhibit 2, Mitigating Systems Screening Questions, the finding was determined to be very low safety significance (Green) because it:

(1) was not a design deficiency,

(2) did not represent a loss of system and/or function,

(3) did not represent an actual loss of function of at least a single train for longer than its technical specification allowed outage time,

(4) did not represent a loss of probabilistic assessment (PRA) function of two separate technical specification systems for greater than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />,

(5) did not represent a loss of a PRA system and/or function for greater than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, and

(6) did not result in the loss of high safety-significant, nontechnical specification train.

Cross-Cutting Aspect: P.5 - Operating Experience: The organization systematically and effectively collects, evaluates, and implements relevant internal and external operating experience in a timely manner. Specifically, the licensee failed to collect, evaluate, and implement industry operating experience associated with filling and venting EDG jacket water/intercooler system following maintenance.

Enforcement:

Violation: Technical Specification 5.4.1.a, requires, in part, that written procedures be established, implemented, and maintained covering the applicable procedures recommended in Appendix A to Regulatory Guide 1.33, Quality Assurance Program Requirements, Revision 2, February 1978. Regulatory Guide 1.33, Appendix A, Section 9, Procedures for Performing Maintenance, requires, in part, that maintenance should be properly preplanned and performed in accordance with written procedures, documented instructions, or drawings appropriate to the circumstances. The licensee established Procedure SYS KJ-130, Revision 13, to fill and vent the EDG jacket water and intercooler system.

Contrary to the above, from February 19, 2020 to February 10, 2022, the licensee failed to maintain written procedures, documented instructions, or drawings appropriate to the circumstances to filling and venting the EDG jacket water and intercooler system.

Specifically, the licensee failed to correct inadequate procedural guidance associated with filling and venting the EDG jacket water and intercooler system in accordance with Procedure SYS KJ-130. This condition resulted in air binding the EDG A jacket water keep warm pump and damaging the pump seal that resulted in jacket water leakage greater than allowed to support EDG operability.

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

Failure to Schedule Preventive Maintenance to Prevent Unacceptable Preconditioning Cornerstone Significance Cross-Cutting Report Aspect Section Mitigating Green None (NPP) 71111.22 Systems NCV 05000482/2022001-03 Open/Closed The inspectors identified a Green finding and associated non-cited violation of Title 10 of the Code of Federal Regulations, Part 50 (10 CFR Part 50), Appendix B, Criterion V, Instructions, Procedures, and Drawings, for the licensee failure to accomplish instructions, procedures, or drawings appropriate to the circumstances that would have prevented unacceptable preconditioning of the 125 Vdc battery chargers. Specifically, the licensee failed to accomplish Procedure AI 29B-003, Guidance to Prevent Unacceptable Preconditioning Prior to Testing, Revision 2, to not schedule preventive maintenance prior to conducting as-found 125 Vdc battery charger technical specification surveillance testing.

This resulted in three examples of unacceptable preconditioning the 125 Vdc battery chargers.

Description:

The inspectors reviewed previously performed 18-month 125 Vdc battery charger operational surveillance tests that were performed in accordance with (IAW)

Procedure STS MT-020, 125 Volt DC Battery Charger Operational Test, Revision 26B, to verify the requirements of Surveillance Requirement 3.8.4.6 were met. Specifically, the 125 Vdc battery chargers supplied greater than or equal to 300 amps at greater than or equal to 128.4 V for greater than or equal to 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />. During this review, the inspectors identified the licensee was performing 125 Vdc battery charger preventive maintenance (PM) IAW Procedure MPE E051Q-01, Semi-Annual Cleaning and Testing of Internal Components in Battery Chargers, Revision 20, prior to performing the 125 Vdc battery charger as-found technical specifications surveillance testing. Additionally, the inspector identified three work orders that disturbed the as-found condition of the 125 Vdc battery chargers prior to performing Procedure STS MT-020 and determined it was unacceptable preconditioning IAW NRC Inspection Manual Part 9900 Technical Guidance, Maintenance - Preconditioning of Structures, Systems, and Components (SSC) before Determining Operability, and licensee Procedure AI 29B-003, Revision 2. Specifically, the inspectors identified the following during their inspection activities:

Inspection Manual Part 9900 Technical Guidance defines unacceptable preconditioning as; The alteration, variation, manipulation, or adjustment of the physical condition of the SSC [structures, systems, and components] before or during technical specification surveillance testing that will alter one or more of the SSCs operational parameters which results in acceptable test results. Such changes could mask the actual as-found condition of the SSC and possibly result in an inability to verify the operability of the SSC. In addition, unacceptable preconditioning could make it difficult to determine whether the SSC would perform its intended function during an event in which the SSC might be needed. The specific example of unacceptable preconditioning for electrical equipment was Inspectors noted that electrical loads were removed from a number of 480 V circuit breakers before surveillance testing was performed. In addition, surveillance procedures instructed technicians to inspect, clean, and lubricate several breakers before performing as-found testing. This example is similar to what occurred in Work Orders 18-441067-000, 18-444596-000, and 19-452686-000.

Work Order 18-441067-000: The licensee replaced current and sensing card for train A 125 Vdc distribution system battery charger prior to performing as-found surveillance testing.

Work Order 18-444596-000: The licensee replaced electrocyte capacitors for train A 125 Vdc distribution system battery charger NK021 prior to performing as-found surveillance testing.

Work Order 19-452686-000: The licensee replaced electrocyte capacitors for train B 125 Vdc distribution system battery charger prior to performing as-found surveillance testing.

In each case, the equipment replaced within the 125 Vdc battery chargers impacted the ability to verify as-found operability of the battery chargers. Each component was replaced due to visible damage on the component, such as scorch marks and dents.

Procedure AI 29B-003 has the following statements:

o Step 6.3.1 states in part, that Initiative to integrate maintenance and surveillance testing may inadvertently introduce unrecognized equipment preconditioning. The practice of scheduling a routine surveillance test to follow a maintenance activity so that test can satisfy the periodic surveillance requirement as well as serve as the post-maintenance test could result in unacceptable preconditioning.

Example: Following maintenance, the baseline performance or condition data must be recorded if a post-maintenance test is used as the operability test of record. The baseline data are necessary to compare to future test data to determine equipment conditions that develop over time. However, in some circumstance recording post-maintenance baseline data in lieu of recording the as-found data could prevent detection of equipment performance problems.

o Step 6.4.1, states in part, that Except where there is a need to protect personnel or prevent equipment damage, preventive maintenance should not be routinely performed before surveillance testing.

From the above information, the inspectors determined there was not a need to perform PMs prior to as-found technical specification surveillance testing to protect personnel or prevent equipment damage, therefore scheduling PMs IAW Procedure MPE E051Q-01 prior to performing as-found technical specification surveillance testing IAW Procedure STS MT-020 was unacceptable preconditioning of the 125 Vdc battery chargers. The inspectors informed the licensee of their concern of unacceptable preconditioning of 125 Vdc battery chargers and they initiated CR 10011968.

Corrective Actions: The licensee performed as-found technical specification testing of train A 125 Vdc distribution system battery charger NK023 prior to perform PMs IAW Procedure MPE E051Q-01.

Corrective Action References: CR 10011968

Performance Assessment:

Performance Deficiency: The licensees failure to schedule PMs to prevent unacceptable preconditioning of 125 Vdc battery chargers prior to technical specification surveillance testing was a performance deficiency.

Screening: The inspectors determined the performance deficiency was more than minor because it was associated with the Human 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 licensee scheduled PMs prior to performing as-found 125 Vdc battery charger technical specification required surveillance testing, which resulted in three examples of unacceptable preconditioning and the inability to verify operability of the 125 Vdc battery chargers.

Significance: The inspectors assessed the significance of the finding using Appendix A, The Significance Determination Process (SDP) for Findings At-Power. The finding was determined to be of very low safety significance (Green) because it

(1) was not a design deficiency,

(2) did not represent a loss of system and/or function,

(3) did not represent an actual loss of function of at least a single train for longer than its technical specification allowed outage time,

(4) did not represent a loss of the probability risk analysis function of two separate technical specification systems for greater than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />,

(5) did not represent a loss of probability risk analysis system and/or function for greater than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, and

(6) did not result in the loss of a high safety-significant, nontechnical specification train.

Cross-Cutting Aspect: Not Present Performance. No cross-cutting aspect was assigned to this finding because the inspectors determined the finding did not reflect present licensee performance.

Enforcement:

Violation: Title 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, requires in part, that activities affecting quality shall be prescribed by documented instructions, procedures, or drawings of a type appropriate to the circumstances and shall be accomplished in accordance with these instructions, procedures, or drawings. The licensee established Procedure AI 29B-003 as the implementing procedure to prevent unacceptable preconditioning due to performing PM prior surveillance testing in accordance with Step 6.4.1, which states in part, that Except where there is a need to protect personnel or prevent equipment damage, PM should not be routinely performed before surveillance testing..

Contrary to the above, prior to February 7, 2022, the licensee failed to ensure that an activity affecting quality was accomplished in accordance with documented instructions, procedures, or drawings. Specifically, the licensed failed to accomplish Procedure AI 29B-003, Step 6.4.1 when scheduling 125 Vdc battery charge PM prior to performing as-found technical specification surveillance testing. During three previous maintenance activities, components within the 125 Vdc system were replaced prior to taking as-found amperage and voltage surveillance readings to ensure that the system was operable prior to conducting maintenance, with no need to protect personnel or prevent equipment damage.

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