ARKANSAS NUCLEAR ONE - INTEGRATED INSPECTION REPORT 05000313/2020002 AND 05000368/2020002

Dear Mr. Dinelli:

On June 30, 2020, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at Arkansas Nuclear One. On July 8, 2020, the NRC inspectors discussed the results of this inspection with Mr. J. Sullivan, General Manager of Plant Operations, and other members of your staff. The results of this inspection are documented in the enclosed report.

Two findings of very low safety significance (Green) are documented in this report. Both findings involved violations of NRC requirements. We are treating these violations as non-cited violations (NCVs) consistent with Section 2.3.2 of the Enforcement Policy.

If you contest the violations or the significance of the violations documented in this inspection report, you should provide a response within 30 days of the date of this inspection report, with the basis for your denial, to the U.S. Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington, DC 20555-0001; with copies to the Regional Administrator, Region IV; the Director, Office of Enforcement; and the NRC Resident Inspector at Arkansas Nuclear One. This letter, its enclosure, and your response (if any) will be made available for public inspection and copying at http://www.nrc.gov/reading-rm/adams.html and at the NRC Public Document Room in accordance with Title 10 of the Code of Federal Regulations 2.390, Public Inspections, Exemptions, Requests for Withholding.

List of Findings and Violations

Failure to Design Alarm Chassis with Reflash Capability with Multiple Inputs Cornerstone Significance Cross-Cutting Aspect Report Section Mitigating Systems Green NCV 05000313/2020002-01 Open/Closed None 71111.15 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 III, Design Control, for the licensees failure to assure that the applicable design basis requirements, associated with the Unit 1 safety-related electrical equipment room high temperature alarm chassis, were reviewed for suitability of application of materials, parts, equipment, and processes.

Specifically, the licensee failed to ensure an alarm chassis with multiple inputs had alarm reflash capability to ensure operators would identify a degraded condition associated with the safety-related electrical equipment room emergency chiller system and take appropriate operator action during a loss of coolant accident.

Failure to Take Corrective Actions for Conditions Adverse to Quality Cornerstone Significance Cross-Cutting Aspect Report Section Mitigating Systems Green NCV 05000368/2020002-02 Open/Closed None 71152 The inspectors reviewed a self-revealed, Green finding and associated non-cited violation of Title 10 of the Code of Federal Regulations, Part 50, Appendix B, Criterion XVI, Corrective Action, associated with the licensees failure to assure that conditions adverse to quality, such as, defective material and equipment are corrected. Specifically, the licensee identified through a visual examination (VT-3) of a Unit 2 safety-related snubber and associated attachments identified multiple degraded conditions, but failed to take corrective actions to correct the defective material, a condition adverse to quality. Consequently, the failure to correct the adverse condition contributed to the failure of the snubber.

Additional Tracking Items

None.

Unit 1 began the inspection period at full power. On April 1, 2020, power was lowered to 80 percent as requested by the transmission system operator to support the 500 kV Mabelvale line maintenance outage. The unit was returned to full power on April 3, 2020.

Unit 2 began the inspection period in shutdown for Refueling Outage 2R27, which started on March 13, 2020. On April 20, 2020, Unit 2 commenced a reactor startup and the reactor was made critical. The unit was returned to full power on April 26, 2020.

On May 23, 2020, Unit 1 and Unit 2 power was lowered to 71 percent as requested by the transmission system operator to facilitate repairs on the 500 kV Mabelvale line. Unit 1 and Unit 2 were returned to full power on May 24, 2020.

On June 1, 2020, Unit 1 power was lowered to 30 percent to perform main generator voltage regulator power supply replacement and turbine governor valve stroke testing, and then the unit was returned to full power where it remained for the rest of the reporting period except for minor power reductions to support scheduled surveillances.

On June 2, 2020, Unit 2 power was lowered to 70 percent to perform circulation pump B bearing repairs. The unit was returned to full power on June 6, 2020, where it remained for the rest of the reporting period except for minor power reductions to support scheduled surveillances.

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 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 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

Failure to Design Alarm Chassis with Reflash Capability with Multiple Inputs Cornerstone Significance Cross-Cutting Aspect Report Section Mitigating Systems

Green NCV 05000313/2020002-01 Open/Closed None 71111.15 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 III, Design Control, for the licensees failure to assure that the applicable design basis requirements, associated with the Unit 1 safety-related electrical equipment room high temperature alarm chassis, were reviewed for suitability of application of materials, parts, equipment, and processes. Specifically, the licensee failed to ensure an alarm chassis with multiple inputs had alarm reflash capability to ensure operators would identify a degraded condition associated with the safety-related electrical equipment room emergency chiller system and take appropriate operator action during a loss of coolant accident.

Description:

The inspectors reviewed the current license and design basis associated with the safety-related electrical equipment room emergency chiller system, Procedure OP-1203.012-N, Annunciator K16 Corrective Action, Revision 49, and Procedure OP-1104.027, Battery and Switchgear Emergency Cooling System, Revision 51. From this review, the inspectors identified the following:

• Unit 1 Safety Analysis Report: The electrical equipment room emergency chillers are designed to maintain a maximum temperature of 120 degrees Fahrenheit (F) in the safety-related 4160 V switchgear rooms, the electrical equipment rooms, and the battery/DC rooms during a loss of coolant accident (LOCA). Long-term operator actions may be required to open doors to the south electrical room (Room 104) to maintain temperatures within limits. The long-term operator actions were established in 2007 when it was identified by the licensee that during worst-case accident/ambient conditions, even if the south emergency switchgear room chiller VCH-4B and the south electrical equipment room emergency unit cooler VUC-14D are operating as designed, action was required to maintain operability of electrical equipment in the room. Additionally, Calculation CALC-91-E-0090-10, ANO-1 North Electrical Room 149 HVAC Evaluation, Revision 4, determined that the maximum temperature of north electrical equipment room (Room 149) was 118.4 degrees F during a LOCA.

Room 149s maximum temperature occurs with the north emergency switchgear room chiller VCH-4A and north equipment room emergency unit cooler VUC-14B are operating as designed.

• Procedure OP-1203.012-N: The safety-related electrical equipment room temperature high alarm setpoint was 104 degrees F and has multiple inputs from temperature switches in safety-related electrical equipment rooms and does not have reflash capability. The purpose of this alarm is to warn control room operators of a degraded condition with the safety-related electrical equipment room emergency chiller system. Additionally, if the alarm is received during a LOCA, Procedure OP-1203.012-N instructs operators to perform actions in accordance with Procedure OP-1104.027.

• Procedure OP-1104.027: In the worst-case LOCA ambient conditions, the following actions are needed as soon as 115 hours0.00133 days <br />0.0319 hours <br />1.901455e-4 weeks <br />4.37575e-5 months <br /> after the accident, but they are taken promptly whenever a room high temperature alarm (104 degrees F) is received, even if the south emergency switchgear room chiller VCH-4B and south electrical equipment room emergency unit cooler VUC-14D are operating as designed. The operator action is to open and hold open the door for the electrical equipment room (Door 49) and the missile door for the electrical equipment room (Door 62) as soon as practicable and within 115 hours0.00133 days <br />0.0319 hours <br />1.901455e-4 weeks <br />4.37575e-5 months <br />. The inspectors did not identify any procedural requirement to monitor the temperatures of unaffected safety-related electrical equipment rooms, once a safety-related electrical equipment room high temperature alarm has been received during LOCA for Room 104 or Room 149.

From the information above, the inspectors concluded without reflash capability of the safety-related electrical equipment room temperature high alarm or additional monitoring of the unaffected safety-related electrical rooms, operators would not be able to identify a degraded condition associated with the safety-related electrical equipment room emergency chiller system and take appropriate alarm card corrective actions during a LOCA. The licensee entered this deficiency into the corrective action program as Condition Report CR-ANO-1-2020-00668.

Corrective Actions: The licensee initiated a procedure improvement form, PIF-1-20-0130, to update Procedure OP-1104.027 to implement additional monitoring when a room temperature high alarm is received and will not clear. Additionally, the licensee initiated a design change to create a reflash capability for the electrical equipment room temperature high alarm.

Corrective Action References: Condition Report CR-ANO-1-2020-00668

Performance Assessment:

Performance Deficiency: The licensees failure to design an alarm chassis with multiple safety-related electrical room high temperature alarms with reflash capability was a performance deficiency.

Screening: The inspectors determined the performance deficiency was more than minor because it was associated with the design control 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 licensees failure to design an alarm chassis with multiple safety-related electrical room high temperature alarms with reflash capability would prevent operators from identifying a degraded condition associated with the safety-related electrical equipment room emergency chiller system and from performing appropriate alarm card corrective actions during a LOCA.

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 or qualification impacting operability or probabilistic risk assessment (PRA)functionality,

(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: None. A cross-cutting aspect was not assigned to this finding because the performance deficiency occurred in 2007 and, therefore, is not indicative of current licensee performance.

Enforcement:

Violation: As required, in part, by 10 CFR Part 50, Appendix B, Criterion III, Design Control, measures shall be established to assure that applicable regulatory requirements and the design basis, as defined in 50.2 and as specified in the licensee application, for those structures, systems, and components to which this appendix applies. Measures shall also be established for the selection and review for suitability of application of materials, parts, equipment, and processes that are essential to the safety-related functions of the structures, systems, and components.

Contrary to the above, from April 2007 to April 2020, the licensee failed to establish measures to assure that applicable regulatory requirements and the design basis, as defined in 50.2 and as specified in the licensee application that for those structures, systems, and components to which this appendix applies. Measures shall also be established for the selection and review for suitability of application of materials, parts, equipment, and processes that are essential to the safety-related functions of the structures, systems, and components for the Unit 1 safety-related electrical equipment room high temperature alarm chassis. Specifically, the licensee failed to ensure this alarm chassis with multiple inputs had alarm reflash capability to ensure operators would identify a degraded condition associated with the safety-related electrical equipment room emergency chiller system and take appropriate operator action during a LOCA.

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

Failure to Take Corrective Actions for Conditions Adverse to Quality Cornerstone Significance Cross-Cutting Aspect Report Section Mitigating Systems

Green NCV 05000368/2020002-02 Open/Closed None 71152 The inspectors reviewed a self-revealed, Green finding and associated non-cited violation of 10 CFR Part 50, Appendix B, Criterion XVI, Corrective Action, associated with the licensees failure to assure that conditions adverse to quality, such as, defective material and equipment are corrected. Specifically, the licensee identified through a visual examination (VT-3) of a Unit 2 safety-related snubber and associated attachments identified multiple degraded conditions, but failed to take corrective actions to correct the defective material, a condition adverse to quality. Consequently, the failure to correct the adverse condition contributed to the failure of the snubber.

Description:

During the 2020 Unit 2 spring refueling outage, a Lisega hydraulic snubber, 2CCA-15-H60, was found fully disconnected on the reactor building floor during the initial walkdown performed. During walkdowns to identify the source of the disconnected snubber, snubber 2CCA-13-H4 was also identified as disconnected at the pipe clamp. The snubber remained within the degraded pipe clamps, but the load pin could not be located. This condition prompted the licensee to complete a stress analysis to assure that the structural integrity of the piping system remained within design. The licensee concluded that after snubber 2CCA-13-H4 lost its load pin at the pipe clamp, the added vibration experienced in the system resulted in the failure of snubber 2CCA-15-H60. Prior to plant start-up, the inspectors reviewed the vibration analysis and did not identify any issues with continued operation of the pressurizer spray line system.

A review of the past maintenance history for snubber 2CCA-13-H4 revealed that in 2009, snubber 2CCA-13-H4 had been visually examined (VT-3) twice during maintenance activities per WO 51667491. The work was completed using Procedure 1306.003, Visual Inspection, VT-3 & Limited Operability Testing of Snubbers, Revision 28. During the initial VT-3 examination, the licensee documented multiple degraded conditions detailed as spherical bearing damaged, load stud worn and deformed, extension worn down in pipe clamp, excessive clearance from worn extension and bearing damage, and an unacceptable clearance on the structure clevis. The non-destructive examination (NDE) report referenced Condition Report CR-ANO-2-2009-02376 as a corrective action. The inspectors reviewed this condition report and noted that it was closed to Work Order WO 51667491, which performed the removal and installation of several snubbers in accordance with Procedure 1402.130, Snubber Removal and Installation, Revision 51. As required by the procedure, the licensee performed a second VT-3 examination on snubber 2CCA-13-H4 after its maintenance had been completed. The inspectors noted that the second NDE report documented the following degraded conditions: extension paddle has excessive wear, bearing does not have enough surface contact with paddle, pipe clamp has excessive wear from extension paddle rubbing in pipe clamp. The NDE report did not reference any additional corrective actions. The inspectors reviewed the Adverse Condition Analysis (ACA)report as documented in Condition Report CR-ANO-2-2020-0867. The inspectors concluded that no additional corrective actions (i.e., condition reports, work orders, evaluations, etc.) had been taken subsequent to the second VT-3 examination of snubber 2CCA-13-H4.

Corrective Actions: The licensee replaced snubber 2CCA-13-H4 and repaired the degraded pipe clamps.

Performance Assessment:

Performance Deficiency: The licensees failure to take corrective actions following the identification of multiple degraded conditions during a VT-3 examination of snubber 2CCA-13-H4 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 correct the condition adverse to quality resulted in the failure of snubber 2CCA-13-H4.

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 or qualification impacting operability or PRA functionality,

(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: None. A cross-cutting aspect was not assigned to this finding because the performance deficiency occurred in 2009 and, therefore, is not indicative of current licensee performance.

Enforcement:

Violation: As required, in part, by 10 CFR Part 50, Appendix B, Criterion XVI, Corrective Action, measures shall be established to assure that conditions adverse to quality, such as failures, malfunctions, deficiencies, deviations, defective material and equipment, and nonconformances are corrected.

Contrary to the above, from August 15, 2009 to March 14, 2020, the licensee failed to correct a condition adverse to quality associated with snubber 2CCA-13-H4 defective material and equipment. Specifically, the VT-3 examination identified structural degradation of the extension paddle and pipe clamp of snubber 2CCA-13-H4, but failed to correct or evaluate these conditions adverse to quality.

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

Observation: Semiannual Trend Review 71152 The inspectors reviewed the licensees corrective action program, performance indicators, system health reports, and other documentation available to help identify performance trends that might indicate the existence of a more significant safety issue. The inspectors verified that the licensee was taking corrective actions to address the identified adverse trends. The inspectors did not review any cross-cutting themes because none existed at the site.

To verify that the licensee was taking corrective actions to address identified adverse trends that might indicate the existence of a more significant safety issue, the inspectors reviewed the corrective action program documentation associated with a potential adverse trend in management of obsolete equipment from the time period of December 2019 through June 2020. Selected examples of these events included:

• CR-ANO-1-2020-0363: There are 27 overcurrent relays associated with the 4160 Vac safety-related motors that are scheduled for setting changes during the spring 2021 Unit 1 refueling outage. These overcurrent relays are obsolete and replacements are not available. The inspectors did not identify a bridging strategy or an equivalent replacement relay. Unavailability of these relay replacements could extend the outage time and result in a vulnerability of safety systems.

• CR-ANO-2-2020-2602: The emergency diesel generator B heat exchanger drain valve (2SW-1125) was leaking and the handwheel slipped when valve tightening was attempted. Work Order 542027 was issued to repair the valve, but after the valve was disassembled it was determined that parts were unavailable and cannot be purchased because of obsolescence. The valve was reinstalled in the as-found condition and was externally watertight. An equivalent replacement will need to be identified and procured to repair the drain valve leakage. Leakage through this valve could potentially cause a loss of flow to the heat exchanger and threaten the inventory of the emergency cooling pond during situations where it is the source of service water.

• CR-ANO-2-2020-1060: During performance of Procedure OP-2305.003, Emergency Safety Feature Response Time Test, Revision 41, it was determined that relay 2C40-K210B in the containment isolation actuation system (CIAS) had failed.

Work Order 541387 was written to replace the failed relay, but an exact replacement was not available, and an equivalency review was needed before the relay could be replaced. Although a replacement relay was identified and used, the licensee determined that neither the original relay nor the replacement relay were still being manufactured and that spare parts were in very limited supply. The failed relay was kept and designated to be rebuilt or refurbished so it could be reused. A similar issue was identified with another model of CIAS relay in Condition Report CR-ANO-2-2020-1235. Failure of a CIAS relay could result in an uncontrolled radiological release from containment.

• CR-ANO-2-2020-1786, 1944, 1968, 1970, 2142, and 2143: During performance of Work Order 52864561 to calibrate the steam dump and bypass control system, a valve did not stroke as expected. Subsequent actions ultimately resulted in multiple control system cards needing to be replaced. However, replacement cards were not available and emergent repair of failed cards was necessary. This event delayed the return of Unit 2 to power following Refueling Outage 2R27. Condition Report CR-ANO-2-01944 stated, This event highlighted the obsolescence vulnerability of the SDBC system. Planned replacement of this system is scheduled for the fall 2024 Refueling Outage 2R30, but an adequate bridging strategy was not identified by the inspectors. Failure of the steam dump and bypass control system could cause a significant transient to the reactor and could negatively impact the ability of the plant to be cooled through the steam generators after a plant trip.

• CR-ANO-2-2020-2200: Alarms received in the control room for the alternate AC diesel generator flame detectors prompted troubleshooting that revealed that both the engine flame detectors had failed. These items are obsolete, and no replacements are on site for the repairs. An upgrade of the fire detection system is planned for the 2024-2028 timeframe, but it is not acceptable to have the alarms locked in until that work is done. A work request was generated to resolve this issue. Failure of these flame detectors reduces the ability of the alternate AC diesel generator fire protection system to detect and respond to system fires.

The licensees immediate corrective actions for the recent potential adverse trend in equipment obsolescence included:

• Discussions have occurred among the site engineering staff relative to the sites program for managing obsolescence issues.

• The ANO equipment reliability team has initiated tasks to identify critical spares, document the risk significance of limited spares, and prioritize efforts to address the identified vulnerabilities.

• ANO site engineering has identified equipment obsolescence as an area that needs increased attention. An effort has been initiated to determine the safety significance of obsolescent equipment and to develop a bridging or replacement strategy. The sites goal is to have the affected Tier 1 equipment identified and prioritized by the end of July 2020.

The inspectors noted the following:

1. The licensees immediate actions have not been in effect long enough to know

whether they will reduce the number of obsolete equipment issues that are happening at the site.

2. Planning for replacement of obsolete components has resulted in the determination of

equivalence when it actually did not exist. This has caused the inability to complete work orders and the necessity to defer that work until suitable parts can be identified and obtained.

3. Continued aging of the plants will result in additional items becoming obsolete and

may challenge the sites ability to prevent future operability and functionality concerns.

4. The sites method of dealing with obsolescence issues has been more reactive than

proactive, but that is being changed with a new initiative in the engineering department. Obsolescent components exist in both safety and nonsafety systems with a potential increasing site risk to initiating events and unplanned unavailability of systems needed to mitigate design basis events. Many potential benefits can be realized from a proactive response to addressing obsolescence issues, such as it will potentially reduce site risk due to obsolescent equipment.

5. The site has identified multiple instances of their equipment database not being

updated after obsolete components were replaced with new, equivalent components (Condition Report CR-ANO-2-2019-03085). This weakness has a negative effect on work planning and parts inventory. A rollup Engineering Change (EC-84307) was performed to ensure that current equipment information is captured in the sites Asset Suite database. In the EC, 13 condition reports written in 2019 were identified with issues involving accuracy of the sites equipment database, drawings, or Asset Suite database. It is unclear if an attempt was made to identify similar issues prior to 2019, so database errors may still exist.
