PLANT STATUS
Unit 1 began the inspection period at full power where it remained for the rest of the reporting period except for minor reductions in power to support scheduled surveillances.
Unit 2 began the inspection period in shutdown for Forced Outage 2F19-01, as a result of a fault in reactor coolant pump motor B, which started on May 26, 2019. On July 28, 2019, Unit 2 commenced a reactor startup and the reactor was made critical. The unit was returned to full power on July 30, 2019, where it remained for the rest of the reporting period except for minor reductions in power to support scheduled surveillances and for degraded condenser vacuum conditions.
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 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.

OTHER ACTIVITIES
- TEMPORARY INSTRUCTIONS, INFREQUENT AND ABNORMAL
60855 - Operation of an ISFSI Operation of an ISFSI
- (1) The ANO independent spent fuel storage installation (ISFSI) consisted of four ISFSI pads containing two different cask designs. ANO had loaded 24 canisters of the Energy Solutions ventilated storage cask (VSC) VSC-24 design (Certificate of Compliance (CoC) No. 1007) from 1996 to 2003. Since that time, ANO had been loading HI-STORM 100S Version C overpacks containing either a multi-purpose canister (MPC)-24 or MPC-32 design. At the time of the routine inspection, the HI-STORM-100 ISFSI pads contained a total of 67 overpacks and the licensee was in the process of loading canister 68. ANO was currently loading canisters to the Holtec CoC No. 1014, Amendment 13, and Final Safety Analysis Report (FSAR),

INSPECTION RESULTS
Failure to Install Correct Component and Perform Post Maintenance Testing Cornerstone Significance Cross-Cutting Report Aspect Section Initiating Events Green [H.14] - 71111.19 NCV 05000368/2019003-01 Conservative Open/Closed Bias The inspectors reviewed a self-revealed, Green finding and associated non-cited violation of Arkansas Nuclear One, Unit 2, Technical Specification 6.4.1.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 install the correct diodes for control element assembly hold bus 2C70 and to perform post-maintenance testing to demonstrate component functionality.
Description:
In November 2018, during Refueling Outage 2R26, Work Order 52770071 was issued for replacement/refurbishment of the Unit 2 control element assembly (CEA) hold bus 2C70. The hold bus is designed to provide DC voltage to hold a CEA subgroup in a fixed reactor core location when the normal CEA power supply is unavailable. During the performance of the hold bus work, two diodes of the wrong type were installed. The postmaintenance testing (PMT) in Work Order 52770071, step 4.2, Section 6 (Attachment 1)required verification that the hold bus would hold a CEA subgroup. The PMT was not performed, but a note was added to the work order to indicate that it would be done during a potential forced outage and that the maintenance work order was updated to have a scheduled task prior to reactor startup. However, the testing was not done before the Unit 2 reactor startup following Refueling Outage 2R26. The presence of the two incorrect diodes ensured that transfer of CEA subgroups 1 through 10 to hold bus 2C70 would have resulted in a dropped CEA during power operations. This would have required immediate operator action to reduce power by 28 percent or greater in accordance with technical specifications and Procedure OP-2203.003, CEA Malfunction, Revision 25, and the potential recovery of the dropped CEA or the performance of a reactor shutdown to meet technical specification requirements.
On January 7, 2019, the licensee documented in Condition Report CR-ANO-2-2019-00041 that preventive maintenance on hold bus 2C70 was not fully completed. The condition report referenced two work orders that had not been completed, including Work Order 52770071.
This condition report was closed on January 14, 2019, with no additional corrective actions taken for hold bus 2C70.
On July 27, 2019, during Unit 2s Forced Outage 2FP19-01, the licensee performed a voltage adjustment to lower hold bus 2C70 voltage due to concerns with CEA drop times. The PMT for this maintenance was to place a CEA subgroup onto hold bus 2C70 as a functional test.
When the CEA subgroup was transferred to hold bus 2C70, two CEAs inserted into the reactor core. The licensees troubleshooting of the event determined two incorrect diodes were installed during Refueling Outage 2R26. The licensee entered this issue into the corrective action program as Condition Report CR-ANO-2-2019-02163 and performed a human performance analysis.
The licensees human performance analysis identified two causal factors:
- Inadequate work instruction: Work Standard T23467 had vague open-ended repair instructions without materials identified for the repairs
- Inadequate verification and validation practices: Craft performing the work did not verify that the parts being installed were the correct ones for that component/application The human performance evaluation focused on why the incorrect diodes were installed, but did not determine why the licensee failed to perform the required post-maintenance test prior to reactor startup from Refueling Outage 2R26 and why no additional actions were taken when it was identified in Condition Report CR-ANO-2-2019-00041. The licensee entered this issue into the corrective action program as Condition Report CR-ANO-2-2019-02607 and performed an adverse condition analysis.
Corrective Actions: The licensee replaced the incorrect diodes and performed the required post maintenance testing prior to reactor startup from Forced Outage 2FP19-01. Additionally, the licensee revised the work standard for the hold bus refurbishment to include instructions and materials for the refurbishment.
Corrective Action References: Condition Reports CR-ANO-2-2019-00041, CR-ANO-2-2019-02163, CR-ANO-2-2019-02150, and CR-ANO-2-2019-02607
Performance Assessment:
Performance Deficiency: The licensees failure to properly pre-plan maintenance activities to ensure the correct components were installed and to perform the required post-maintenance testing was a performance deficiency.
Screening: The inspectors determined the performance deficiency was more than minor because if left uncorrected, it would have adversely impacted the equipment performance attribute of the Initiating Events Cornerstone and would have affected the associated cornerstone objective to limit the likelihood of events that upset plant stability and challenge critical safety functions during shutdown as well as power operations. Specifically, if a control element assembly subgroup was transferred to hold bus 2C70 during power operations, it would have resulted in one control element assembly dropping into the reactor core.
Significance: The inspectors assessed the significance of the finding using Appendix A, The Significance Determination Process (SDP) for Findings At-Power. The inspectors determined that the finding had very low safety significance (Green) because the finding did not cause a reactor trip and the loss of mitigation equipment relied upon to transition the plant from the onset of the trip to a stable shutdown condition.
Cross-Cutting Aspect: H.14 - Conservative Bias: Individuals use decision-making-practices that emphasize prudent choices over those that are simply allowable. A proposed action is determined to be safe in order to proceed, rather than unsafe in order to stop. Specifically, the licensee failed to consider the risk-significance of the proposed action to defer postmaintenance testing following hold bus 2C70 diode replacement to ensure equipment functionality. Additionally, the licensee failed to consider the risk-significance of the proposed action to close Condition Report CR-ANO-2-2019-00041 with no additional actions to verify hold bus 2C70 functionality.
Enforcement:
Violation: Unit 2 Technical Specification 6.4.1.a requires, in part, that written procedures be established, implemented, and maintained covering the applicable procedures in Appendix A to Regulatory Guide 1.33. Appendix A, Section 9.a, states, in part, that maintenance that can affect the performance of safety-related equipment should be properly preplanned and performed in accordance with written procedures, documented instructions, or drawings appropriate to the circumstances. Work Order 52770071, step 4.1, provides instructions to refurbish the hold bus 270 power supply, and step 4.2, Section 6 (Attachment 1), provides instructions to perform the post maintenance testing of the hold bus 2C70 power supply.
Contrary to the above, on November 2018, the licensee failed to properly preplan and implement maintenance that can affect the performance of safety-related equipment.
Specifically, the licensee failed to have adequate work instructions in Work Order 52770071, step 4.1, to install the correct diodes for hold bus 2C70 and implement step 4.2 to perform Section 6 (Attachment 1), post maintenance testing. This condition resulted in the installation of the incorrect diodes and the failure to perform post maintenance testing for hold bus 2C70.
Enforcement Action: This violation is being treated as a non-cited violation, consistent with Section 2.3.2 of the Enforcement Policy.
Failure to Promptly Identify and Correct a Condition Adverse to Quality Cornerstone Significance Cross-Cutting Report Aspect Section Initiating Events Green [P.2] - 71152 NCV 05000368/2019003-02 Evaluation Open/Closed The inspectors reviewed a self-revealed, Green finding and associated non-cited violation of 10 CFR Part 50, Appendix B, Criterion XVI, Corrective Action, for the licensees failure to promptly identify and correct conditions adverse to quality, such as failures, malfunctions, deficiencies, deviations, defective material and equipment, and nonconformances.
Specifically, the licensee failed to promptly identify and correct damage to Unit 2s reactor coolant pump C controlled bleed off piping in 2011, 2015, and 2017, when insulation was removed making the piping available for inspection.
Description:
In May 2019, during full power operations, Unit 2 operators observed an unexplained rise in the containment sump level which was not commensurate with the existing plant conditions. This prompted the operators to commence a reactor coolant system leak investigation. Prior to completion of the online leak investigation, Unit 2 experienced a reactor trip and entered Forced Outage 2FP19-01, as a result of a fault in reactor coolant pump motor B. During Forced Outage 2FP19-01, the licensee discovered that reactor coolant pump C controlled bleed off (CBO) piping was leaking due to a through wall crack in a socket weld. The licensee entered this issue into the corrective action program as Condition Report CR-ANO-2-2019-01365 and performed an adverse condition analysis.
The licensees adverse condition analysis determined the direct cause associated with the through wall leak on the CBO piping was a crack initiated from external damage from a thin cutting tool. The CBO piping was also subjected to vibration loads, which resulted in the propagation of a through wall crack due to cyclic fatigue. The causal factor was poor maintenance work practices that led to significant CBO piping damage which likely took place during 2008 when the removal/replacement of fibrous insulation on various lines was authorized due to damaged insulation. During the insulation removal/replacement, which occurred multiple times since 2008, the licensee did not document any observed damage to the CBO piping.
The licensee documented damage to reactor coolant pump C CBO piping insulation three times since 2011 (Condition Reports CR-ANO-2-2011-00567, CR-ANO-2-2015-03185, and CR-ANO-2-2017-01735), which provided them the opportunity to identify and correct the damage. In each instance, the licensee only addressed the replacement of the insulation, and no instructions were incorporated into the work orders which replaced the insulation to also inspect the underlying CBO piping. The licensee stated that damage to the CBO piping most likely occurred during 2008 when the removal/replacement of fibrous insulation on various lines was authorized due to damaged insulation; however, damage to the CBO piping could also have occurred when the insulation was replaced in 2011 and 2015, and during the permanent removal of the insulation in 2017. The licensees focus was the vibration-induced insulation damage, and the licensee did not thoroughly evaluate the issue to determine if the CBO piping was also damaged. Specifically, the licensee did not use its internal and external operating experience to thoroughly review the vibration-induced insulation damage to identify the CBO piping damage in 2011, 2015, or 2017.
The inspectors noted that NRC Information Notice (IN) 2007-21, Pipe Wear Due to Interaction of Flow Induced Vibration and Reflective Metal Insulation, provided operating experience to licensees that significant wear marks were observed on the outside wall of chemical and volume control system stainless steel piping due to interaction between the piping base metal and the installed reflective metal insulation. The NRC IN stated that the most probable cause of the abrasive wear was flow induced vibration combined with end cap to piping interaction. The NRC IN recommended that licensees review the information for applicability to their facilities and consider actions, as appropriate, to identify and address similar problems, up to and including the periodic removal of insulation to allow visual inspection for piping degradation. Additionally, the licensee had its own internal operating experience associated with damage identified on piping that interfaces with the reactor coolant system. In 1989, 1994, and 2009, the licensee identified cuts on piping (Condition Reports CR-ANO-1-1989-00110, CR-ANO-2-1994-00183, and CR-ANO-2-2009-02680) and, in 2014, gouges were noted during ASME inspections of charging piping to the reactor coolant pump B discharge cold leg (Condition Report CR-ANO-2-2014-01157).
Corrective Actions: The licensee replaced reactor coolant pump A, B, C, and D CBO lines and performed an extent of condition that identified one additional location that required replacement.
Corrective Action Reference: Condition Report CR-ANO-2-2019-01365
Performance Assessment:
Performance Deficiency: The licensees failure to promptly identify and correct a condition adverse to quality when removing reactor coolant pump CBO insulation 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 Initiating Events Cornerstone and adversely affected the cornerstone objective to limit the likelihood of events that upset plant stability and challenge critical safety functions during shutdown as well as power operations. Specifically, the failure to promptly identify and correct the damage on the reactor coolant pump CBO piping resulted in a failed socket weld and a reactor coolant leak, which degraded the safety-related ASME Class II boundary.
Significance: The inspectors assessed the significance of the finding using Appendix A, The Significance Determination Process (SDP) for Findings At-Power. The inspectors determined the finding had very low safety significance (Green) because the finding after a reasonable assessment of degradation
- (1) did not result in exceeding the reactor coolant system leak rate for a small loss-of-coolant accident; and
- (2) likely did not affect other systems used to mitigate a loss-of-coolant accident resulting in a total loss of their function.
Cross-Cutting Aspect: P.2 - Evaluation: The organization thoroughly evaluates issues to ensure that resolutions address causes and extent of conditions commensurate with their safety significance. Specifically, the licensee failed to thoroughly evaluate CBO piping for damage, using internal and external operating experience, when insulation was removed due to vibration induced damage in 2011, 2015, and 2017.
Enforcement:
Violation: Title 10 of the Code of Federal Regulations Part 50, Appendix B, Criterion XVI, Corrective Action, requires that measures shall be established to assure that conditions adverse to quality, such as failures, malfunctions, deficiencies, deviations, defective material and equipment, and nonconformances are promptly identified and corrected.
Contrary to the above, between February 2011 and September 2017, the licensee failed to promptly identify and correct a condition adverse to quality. Specifically, the licensee failed to promptly identify and correct damage to reactor coolant pump C control bleed off line piping which eventually led to a failure of the line and subsequent reactor coolant leak requiring a forced shutdown to make repairs in May 2019.
Enforcement Action: This violation is being treated as a non-cited violation, consistent with Section 2.3.2 of the Enforcement Policy.
