(1)71003 Phase 4 Inspection Activities NRC conducted this Phase 4 Inspection 8 years after the licensee entered the period of extended operation for Unit 1. The inspection confirmed that the licensee continued to meet their commitments, processed any commitment changes in accordance with their commitment management procedure, and evaluated implementation of aging management activities. The period of extended operation included the additional 20 years beyond the original 40-year licensed term. Arkansas Nuclear One, Unit 1, began the period of extended operation after midnight on May 20, 2014. The team determined that the licensee had not processed any commitment changes that impacted the programs selected for detailed review.
As part of the license extension, licensees placed a description of their aging management programs in an Updated Final Safety Analysis Report (UFSAR)supplement. Arkansas Nuclear One, Unit 1 included their aging management program descriptions and commitments in Chapter 16. The licensee developed program implementing procedures or modified existing program procedures that described implementation of their aging management activities.
The team performed detailed reviews of the aging management programs listed in Table 1, Detailed Program Evaluations. The team reviewed license renewal program assessments, commitment changes, engineering evaluations, procedures, program documents, completed tests, completed maintenance activities, nondestructive examination reports, technical reports, correspondence, and drawings. The team did not identify any concerns with the aging management activities for the programs listed in Table 1:

Metal Enclosed Buses 16.2.6.5 Service Water Chemistry Control 16.2.8.
Fire Suppression Sprinkler Surveillance 16.2.19 Service Water Integrity Selective Leaching 16.1.1 Buried Piping This program applied to both Unit 1 and Unit 2 and included the buried piping for the fire water and service water systems. The buried service water piping included the return piping from the plant to the emergency cooling pond and the supply piping from the emergency cooling pond to the intake structure. The emergency cooling pond provided the ultimate heat sink supply in the event of a loss of Lake Dardanelle.
From interviews and a review of Procedure SEP-UIP-ANO, Underground Components Inspection Plan Non-Rad and Rad Piping, Revision 7, the team determined that the licensee had completed an evaluation of a buried pipe section prior to entering the period of extended operation on the Unit 1 emergency cooling water return line (1HBD-13-18). The program required the licensee to inspect for external corrosion any time maintenance activities provided an opportunity. The licensee used the guidelines in NEI 09-14, Guideline for the Management of Buried Piping Integrity, Revision 4, for implementing a risk-informed buried piping program. Procedure EN-DC-343, Underground Piping and Tanks Inspection and Monitoring Program, Revision 13, implemented the buried pipe program high level requirements, including those for license renewal. The program monitored for external corrosion and coordinated with the microbiologically influenced and flow-accelerated corrosion programs that monitor and evaluate internal corrosion.
Procedure CEP-UPT-0100, Underground Piping and Tanks Inspection and Monitoring, Revision 6, contained additional implementing guidance related Procedure EN-DC-343. The procedure
- (1) described the component identification and sampling methodology, inspection methodologies, leak detection and monitoring, preventive actions, repair strategies, and mitigation strategies;
- (2) recommended grouping components and specified at least one direct examination for each high-risk piping group; and
- (3) established guidelines for risk ranking each component based on both an impact assessment and corrosion risk assessment.
The team identified the following observations and potential performance deficiencies, which are described more fully in the Results section of this report:
unresolved item related to the aging management of the internal and external emergency cooling pond piping
observation related to the condition of the cathodic protection system 16.1.2 Electrical Components Aging Management Programs The team reviewed three areas related to aging management of electrical components: sensitive instrumentation circuits, inaccessible nonenvironmentally qualified medium voltage (medium voltage) cables, and metal-enclosed bus ducts, as described below.
Sensitive Instrumentation Circuits Review Procedure EN-FAP-LR-027, License Renewal Sensitive Instrumentation Circuits Review AMP, Revision 3, described the requirements for managing the effects of aging for high voltage, low signal level (5 - 1000 nanoamperes) instrumentation cables. The sensitive instrumentation circuits included the reactor protection system and emergency feedwater initiation circuits. The team confirmed that the licensee had evaluated their circuits prior to entering the period of extended operation.
While questioning whether the licensee had scheduled the required 10-year review, the team identified that personnel were not familiar with the requirement to perform the review. Consequently, the team questioned whether a preventive maintenance task existed to ensure completion of the task.
Since Unit 1 had been in the period of extended operation for 8 years, the team concluded that, although the licensee had not missed performing this task, personnel had a high likelihood of failing to perform this this aging management activity. The team noted that the engineers reviewed the completed calibration results for sensitive instrumentation circuits following each 18-month calibration looking for circuit anomalies. Personnel have sufficient time to complete the evaluation over the next 2 years. In response to this observation, the licensee wrote Condition Report 1-2022-00136. In addition, the team determined that the licensee had established Recurring Commitment R-19368 related to performing the 10-year review. The team determined that this may have identified an action in May 2022 to verify that the licensee had implemented actions to complete the aging management review of sensitive instrumentation circuits.
Nonenvironmentally Qualified Inaccessible Medium Voltage Cable Program Procedure EN-DC-346, Cable Reliability Program, Revision 8, prescribed the requirements for implementing the program in response to both maintenance rule and license renewal requirements. The licensee included cables related to powering safety -related pumps and cables that support offsite power supply that would be lost in the event of a station blackout. For the cables included because of license renewal, the licensee had installed sump pumps prior to entering the period of extended operation. Engineering Evaluation CALC-ANO1-EE-13-00005, Non-Environmentally Qualified Inaccessible Medium-Voltage Cable and Manhole Review, Revision 0, provided the basis for the licensee-specific program and included the results of the initial tan-delta test results.
Overall, the team determined that the licensee had implemented an aging management program that prescribed appropriate activities for monitoring the effects of aging. The licensee installed sump pumps to keep in-scope cables dry with one exception. The program requires the licensee to maintain the cables dry to prevent degradation of the cables caused by a wet environment. The licensee established a cable program engineer to monitor and evaluate work activities. The licensee performed tan-delta and withstand testing every 6 years as committed, which exceeded the 10-year recommended frequency. However, the team describes in detail in the Results section a Green non-cited violation for the failure to maintain the 22kV cables from the startup transformer to the voltage regulator dry.
Metal-Enclosed Bus Maintenance The team determined that the licensee had processed industry operating experience related to managing the effects of aging of their metal-enclosed busses, as required.
However, because of their license basis, the licensee was not required to formally establish an aging management program for metal-enclosed busses.
Engineering Evaluation CALC-ANO1-EE-11-00001, ANO-1 Screening and Aging Management Review of Electrical Components for RIS 2007-016, Revision 0 processed the industry operating experience associated with electrical components as described in Regulatory Information Summary 2007-016, Implementation of the Requirements of 10 CFR 54.37(b) for Holders of Renewed Licenses, Revision 1.
Engineering Evaluation CALC-ANO1-EE-11-00001 performed aging management reviews of the passive, long-lived components that supported the nonsegregated metal-enclosed-buses.
The team determined that the licensees aging management review confirmed several passive long-lived components that required aging management. However, the licensee did not establish a formal aging management program for metal-enclosed busses. The licensee performed maintenance on a 10-year frequency on the nonsegregated metal-enclosed bus ducts. The team reviewed the completed maintenance activities and compared the maintenance against the requirements listed in NUREG-1801, Generic Aging Lessons Learned (GALL) Report, Revision 2. The team identified no issues with the maintenance performed.
16.2.8.4 Fire Suppression Sprinkler Surveillance The team confirmed that NRC baseline inspections reviewed fire protection activities credited for managing the effects of aging. These activities included fire barrier inspections, halon system inspections, fire water system surveillances, and fire sprinkler system surveillances. The licensee elected to change out their sprinkler heads at 50 years as specified in the National Fire Protection Association code. The team reviewed the controls established for replacing the sprinkler heads by review of several work orders.
As a result of reviewing the completed work orders before providing them to the team, the licensee identified discrepancies because the number of sprinkler heads listed on the drawing and listed in the work orders differed from the number of sprinkler heads installed. The licensee documented this deficiency in Condition Report ANO-1-2022-00025. The team verified that the licensee had installed like-for-like sprinkler heads based on temperature and type (pendant or upright). The team identified that the deficiencies resulted in a minor violation and that the licensee initiated corrective actions to reinforce expectations related to stopping work to get work packages corrected.
Selective Leaching The team evaluated the selective leaching program to confirm that the licensee had implemented the required actions to evaluate for the presence of selective leaching in their buried piping systems. The team could not evaluate implementation because the licensee had not completed any aging management review activities related to selective leaching. The licensee had developed a program as described in LR-LAR-2015-00081, Corrective Action 5 and as described in Inspection Report 05000313/2015009. The licensee had identified the systems that would be subject to selective leaching and the population of components that could be sampled. The Unit 2 systems that would be representative of Unit 1 included fire water, service water, and emergency feedwater. A self-assessment, performed to prepare for the inspection, identified that no actions had been taken to ensure that the program activities would be implemented.
The licensee wrote Condition Report ANO-C-2021-2622 to track the corrective actions needed to address this deficiency and implement their selective leaching program. The team determined that the licensee had 6 years remaining until the end of the first 10-year period for Unit

[H.14] -
Conservative Bias 71003 The team identified a Green noncited violation of License Condition 2.c.3 and regulatory requirements because the licensee failed to effectively implement aging management activities. Specifically, the licensee failed to keep inaccessible non-environmentally qualified medium voltage cables dry.
Description:
The team reviewed implementation of the non-environmentally qualified inaccessible medium voltage cable program. Procedure EN-DC-346, Cable Reliability Program, Revision 8, specified requirements to maintain cables dry. The licensee had installed solar powered sump pumps in the manholes to maintain in-scope safety-related cables dry based on their original license renewal application. For all other manholes the licensee used the program option to periodically drain down the manholes.
Engineering Evaluation CALC-ANO1-EE-11-00001, ANO-1 Screening and Aging Management Review of Electrical Components for RIS 2007-016, dated February 16, 2011, identified that the licensee would include 22kV cables that ran from a switchyard voltage regulator to Startup Transformer #1 (X-03) through manholes 24 and 25. The licensee included these cables because they connected the first offsite breaker from the switchyard to the normal offsite power supply components. The team determined that that the licensee had not provided solar powered sump pumps for the manholes that included this in-scope cable.
The team determined that the licensee had not appropriately established manual inspections and pumping frequencies to maintain the cables dry. From review of surveillance trends associated with manholes MH-11, MH-13, MH-24, MH-25, MH-26, and MH1VR1, the team determined that the licensee pumped down the manholes each time they performed the monthly surveillance. The team confirmed that the licensee had brown ethylene propylene and red ethylene propylene cables installed for the 22kV circuits, which were not qualified to be continuously wet or submerged. The cables of interest were located on the floor of the manholes and continued to sit in 1 inch of water even when dewatered. The team determined that the licensee had replaced their cables in the mid-nineties. The red ethylene propylene cable jackets are manufactured to be more resistant to moisture intrusion. The cables are continuously energized. The last set of testing confirmed no degradation of the cable insulation.
Procedure EN-DC-346, Section 8.6 provides the requirements to perform manhole inspections in accordance with the preventive maintenance template and to prevent cable submergence, if possible, to increase the longevity of the insulation system. Step 8.6.2.a specifies, Install sump pumps wherever practical in manholes, vaults, and duct systems which contain Medium Voltage In-scope Cable List (MVICL) or Low Voltage In-scope Cable List (LVICL) cables that have the potential for submergence. The team determined that the licensee included safety related, nonsafety-related, maintenance rule scoped, and license renewal scoped cables. Step 8.6.2.b specifies, if manual inspections and pumping are used to maintain a cable system dry, then
- (1) ensure the intervals are sufficient to keep the cables dry;
- (2) adjust the intervals as necessary, based on inspection results; and
- (3) if cable rewetting occurs, use the corrective action process for trending the occurrence and as found water levels; perform an evaluation of the submerged cable. The team confirmed that the same requirements existed since the beginning of the period of extended operation (i.e.,
Procedure EN-DC-346, Revision 6, step 5.6.2.b and Revision 7, Step 8.6.2.b).
Corrective Actions: The licensee placed the issue in their corrective action program to ensure that actions would be taken to stop water from entering the manholes or to install sump pumps.
Corrective Action References: Condition Report ANO-C-2022-00553
Performance Assessment:
Performance Deficiency: The team determined that the failure to implement the aging management requirements for the in-scope inaccessible medium voltage cables was a performance deficiency. Specifically, the licensee failed to maintain the cables dry.
Screening: The team 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 licensee could not assure that electrical cables designed to be dry or wetted would continue to function when called upon because they had been submerged.
Significance: The team assessed the significance of the finding using Inspection Manual Chapter 0609, Appendix A, The Significance Determination Process (SDP) for Findings At-Power. The team determined that the finding screened to green because the deficiency potentially affected the qualification of cables that facilitate power to the safety-related offsite power feed. The team consulted with the senior reactor analyst who confirmed that any risk associated with this deficiency would be dominated by the at-power conditions. Because the cables had been replaced with material more resistant to degradation caused by moisture, were continuously energized, and the last test performed confirmed the integrity of the cable insulation.
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 to proceed, rather than unsafe in order to stop. Specifically, personnel with the knowledge that the cables continued to be continuously wet did not question or take action to meet the aging management program requirements.
Enforcement:
Violation: Operating License No. DPR-51, License Condition 2.c.(3) states, in part, that the safety analysis report supplement submitted pursuant to 10 CFR 54.21(d), as revised on March 14, 2001, describes certain future inspection activities to be completed before the period of extended operation. The licensee shall complete these activities no later than May 20, 2014.
Updated Final Safety Analysis Report Section 16.1.2, Electrical Component Inspection, states, in part, that the scope of the inspection program includes cables exposed to wet environments and that inaccessible medium-voltage cables exposed to significant moisture and voltage will either be tested for the presence of aging effects or a replacement program for these cables will be developed.
Procedure EN-DC-346, Cable Reliability Program, used to implement Updated Final Safety Analysis Report, Section 16.1.2, Revisions 6, 7, and 8, Steps 5.7[2](b), 8.6.2.b, and 8.6.2.b, respectively, require, in part, that if manual inspections and pumping are used to maintain a cable system dry, then ensure the intervals are sufficient to keep the cables dry and adjust the intervals as necessary based on inspection results. If cable rewetting occurs, use the corrective action process for trending the occurrence and as found water levels and perform an evaluation of the submerged cables.
Contrary to the above, from May 20, 2014, to April 11, 2022, for manual inspections and pumping used to maintain a cable system dry, the licensee failed to ensure the pumping intervals were sufficient to keep the cables dry and to adjust the intervals as necessary based on inspection results. Specifically, the licensee failed to ensure that electrical cables identified for aging management inspection activities were maintained dry as designed and specified in Procedure EN DC 346.
Enforcement Action: This violation is being treated as a non-cited violation, consistent with Section 2.3.2 of the Enforcement Policy.
Unresolved Item (Open)
Condition of Emergency Cooling Pond Buried Piping URI 05000313/2021013-02 71003
Description:
During review of the buried emergency cooling pond service water piping, the team identified several programs that the licensee had identified as managing the effects of aging on both the exterior and interior of the piping. Procedure EN-DC-343, Buried Pipe Program, Revision 13, specified requirements to manage the effects of aging caused by exterior corrosion and specified that the program owner would coordinate with the flow-accelerated corrosion and microbiologically influenced corrosion program engineers when an opportunistic excavation occurred. Procedure CEP-UPT-0100, Underground Piping and Tanks Inspection and Monitoring, Revision 6, contained additional guidance related to implementing the buried piping program requirements. The team determined that Condition Report CR-C-2021-00987 documented that volumetric examinations to support a fitness for service evaluation required by Procedure EN-DC-343 had not been performed.
Similarly, Procedure EN-DC-184, NRC Generic Letter 89-13 Service Water Program, Revision 6, implemented requirements for managing the effects of aging on the interior surfaces of the safety-related service water piping. The licensee implemented the site-specific aspects of this program using Procedure SEP-SW-ANO-001, Arkansas Nuclear One (ANO)
NRC Generic Letter 89-13 Service Water Program, Revision 1. Procedure EN-DC-184 identified that nondestructive examination requirements are implemented by Procedure EN-DC-340, Microbiologically Influenced Corrosion (MIC)
Program. Procedure EN-DC-340 states that inadequately treated water sources, open-cycle, once through water sources, and long vertical runs are conducive to the occurrence of microbiologically influenced corrosion. Procedure SEP-MIC-ANO-001, Microbiological Influenced Corrosion (MIC) Program, utilizes risk ranking from other site programs such as buried piping and describes that it supplements the service water integrity program, including meeting license renewal commitments for the service water integrity program, and includes portions of the buried pipe program but monitors for internal pipe corrosion.
The team determined that the application of these procedures has not resulted in the ultimate objective of the procedures to manage the effects of aging of the interior and exterior of the emergency cooling pond buried service water piping to maintain structural and leakage integrity through the end of licensed operations of the facility.
Planned Closure Actions: During a follow-up inspection, NRC inspectors, with the assistance of program experts in buried piping and service water programs from the Office of Nuclear Reactor Regulation, will confirm the following items:
The licensing requirements related to the buried piping, service water, and microbiologically influenced corrosion programs
Whether the licensee has properly implemented the interface requirements among the buried piping, service water, and microbiologically influenced corrosion programs
Whether the licensee has implemented their required external and internal inspections and program requirements
Action plans for inspecting the buried emergency cooling pond supply and return lines
Plans for using carbon fiber reinforced polymer wrap, including interim actions to ensure health of the lines until installation of the repair Licensee Actions: The licensee documented operational data for the buried emergency cooling pond service water piping and documented operability determinations for the system CR-ANO-1-2021-02429, CR-ANO-2-2021-01204, and CR-ANO-C-2021-03142. Additional condition reports related to identified issues included: CR-ANO-C-2019-1633, CR-ANO-C-2021-00987, CR-ANO-C-2022-00804, CR-ANO-1-2022-00171, and CR-ANO-1-2022-00533. The team did not identify any current concerns with operability of the service water system.
