REPORT DETAILS

4OA2 Problem Identification and Resolution

a. Inspection Scope

The inspectors reviewed the following corrective actions related to items identified during the license renewal commitment inspection documented in Inspection Report 05000313/2014007. The inspectors selected these items to verify that the licensee had implemented appropriate corrective actions. If the actions were not completed, the inspectors evaluated the proposed implementation dates of the planned corrective actions to ensure they were commensurate with their safety significance.

Specific actions were reviewed related to the following:

1. In Condition Report 2014-00092 the licensee documented several pipe lines within the underground piping corrosion risk model that contained unknown pipe segments caused by incorrect line designations.

2. As documented in Non-Cited Violation 05000368/2014007-01, Condition Report C-2014-00597 described deficiencies related to a failure to re-inspect cracks in the Unit 2 reactor building that exceeded acceptance criteria during previous inspections to ensure the reactor building maintained structural integrity.

3. In WT-WTHQN-2012-00675 the licensee tracked corrective actions that resulted from an operating experience evaluation of Regulatory Issue Summary 2011-005, Information on Revision 2 to The Generic Aging Lessons Learned Report for License Renewal of Nuclear Power Plants, dated July 1, 2011. The licensee determined that the fire protection aging management program needed piping inspections added. In addition, the licensee determined that they needed to develop two new aging management programs.

b. Findings and Observations

The inspectors had the following observations related to the licensees corrective actions:

1. The licensee had updated their database to include the names of the unknown segments.

2. The licensee had performed an effective extent of condition evaluation as part of the corrective actions for Non-Cited Violation 05000368/2014007-01. However, the inspectors determined that the licensee had not revised their procedure to ensure the guidance specified that identified conditions shall be governed by the current American Society of Mechanical Engineers (ASME) code addition and by any additional inspection requirements specified by the responsible engineer.

The licensee tracked this corrective action in Condition Report C-014-00597, Corrective Action 7.

3. The licensee had compared both Units 1 and 2 against Revision 2 of the Generic

Aging Lessons Learned (GALL) Report during the operating experience review of Regulator Issue Summary 2011-005. The licensee identified numerous corrective actions in WT-WTHQN-2012-00675 related to the three aging management programs. The licensee planned to implement both the Unit 1 and Unit 2 corrective actions while completing the Unit 2 license renewal activities.

• The licensee initiated LR-LAR-2015-00081, Corrective Action 3, to track implementation of an above ground tanks aging management program related to periodic tank inspections. The program included the following components: Tank T-3, borated water storage tank; Tank T-41B, quality-condensate storage tank; and Tank 2T-3, refueling water tank.

Some of the corrective actions to be implemented include:

o Compare this aging management program to the GALL Report, Revision 2, program elements. Identify inconsistencies and evaluate for changes to existing Unit 1 and Unit 2 programs and issue actions to ensure any identified changes are implemented.

o Initiate necessary tasks and document changes to provide instructions for ultrasonic testing of the tank bottom thickness.

o Initiate initial inspections within 5 years of entering the period of extended operation for Unit 1 and Unit 2.

o Establish repetitive task to inspect the tanks every 10 years after the initial inspections.

o Develop the necessary inspection requirements and budget for the periodic inspections.

• The licensee initiated LR-LAR-2015-00081, Corrective Action 4, to track development of program requirements and implementation procedures related to ultrasonic thickness testing of fire water piping. This program applied to Units 1 and 2. Specifically, the corrective action specified, Provide verification of the ultrasonic testing specifications for this program, location of those specifications (what program document),implementation schedule, reporting inspection results to date, and implementing documents (preventive maintenance tasks, model work orders).

• The licensee initiated LR-LAR-2015-00081, Corrective Action 5, to track implementation of a one-time selective leaching aging management program related to piping and component inspections of systems subject to this aging mechanism. This program applied to Units 1 and 2 and will be completed prior to entering the period of extended operation to determine if there is a related aging effect that requires management.

Some of the actions to be implemented include:

o Compare this aging management program to the GALL Report, Revision 2, program elements. Identify inconsistencies and evaluate for changes to existing Unit 1 and Unit 2 programs and issue actions to ensure any identified changes are implemented.

o Develop a one-time aging management program that assesses whether selective leaching is an aging effect requiring management.

o Utilize an XRF alloy analyzer to obtain positive material identification of installed copper and gray cast iron components.

o Define a sample population of components susceptible to selective leaching for evaluation, including fire protection, service water, and auxiliary cooling water systems.

o Determine if previously removed fire protection valve components meet the evaluation criteria.

No findings were identified.

4OA5 Other Activities (71003 - Post Approval License Renewal)

Phase 3 Inspection Activities The Phase 3 Inspection activities are performed after the licensee enters the period of extended operation. The period of extended operation is 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 inspectors performed this inspection to evaluate whether the licensee completed outstanding actions required to comply with the license renewal license condition and commitments and effectively implemented outstanding actions related to select aging management programs.

The inspectors closed Commitments 17850, 17851, 17855, 17872, 17875, and 19358 during this inspection.

In addition, NUREG-1743, Safety Evaluation Report (SER) Related to the License Renewal of Arkansas Nuclear One, Unit 1, did not have an Appendix A that listed the items the NRC considered commitments. Consequently, a senior project manager in the Division of License Renewal issued a memorandum to file entitled, Commitment Lists for Renewed Operating License (ROL) Plants with No Commitment Appendix Attached to Its ROL Safety Evaluation Reports/NUREGs for Use with IP 71003, dated March 6, 2007, Attachment 1.3, Arkansas Nuclear One, Unit 1, that documented 11 commitments (ADAMS ML070640041). The inspectors verified that the licensee had captured these commitments. The inspectors closed the three remaining open commitments, Commitments 5, 7, and 8, during this inspection.

a. Inspection Scope

During this inspection, the inspectors reviewed the licensee actions related to commitments not closed during the Phase 2 license renewal inspection (Inspection Report 05000313/2014007 (ADAMS ML14087A338)). The inspectors evaluated whether the licensee had taken appropriate corrective actions.

The inspectors reviewed program documents, plant procedures, inspection results, and corrective action documents. The inspectors interviewed licensee personnel, including the program owners.

b. Observations 16.1.5 Reactor Vessel Internals Program (17851)

The reactor vessel internals aging management program managed the following aging effects: stress corrosion cracking and irradiation assisted stress corrosion cracking, reduction of fracture toughness by thermal embrittlement and irradiation embrittlement, dimensional changes created by void swelling, and loss of bolted closure integrity because of stress relaxation.

During the previous inspection, the licensee developed, but had not issued, Procedure EN-DC-133, PWR Vessel Internals Program. This procedure described the implementation of the reactor vessel internals inspections that Electric Power Research Institute (EPRI) MRP-227A, Materials Reliability Program: Pressurized Water Reactor Internals Inspection and Evaluation Guidelines, dated December 2011, described as Mandatory or Needed. The licensee planned to submit their reactor vessel internals aging management program for review just prior to entering the period of extended operation to allow for the most accurate possible submittal. The licensee tracked their submittal of the reactor vessel internals aging management program to the NRC by LR-LAR-2010-00176, Corrective Action 204.

During this inspection, the inspectors verified that the licensee had issued Procedure EN-DC-133, Revision 1 that described the fleet approach to managing the effects of aging for the reactor vessel internals. The procedure referenced the site-specific reactor vessel internals aging management program for those plants that had entered the period of extended operation. The inspectors verified that Program Document SEP-PVI-ANO1-001, ANO (PWR) Pressure Vessel Internals Program, Revision 0, appropriately described implementation of the EPRI MRP-227A inspection and monitoring requirements. The inspectors determined that the licensee had submitted their aging management program for review and approval in Letter 1CAN051403, Reactor Vessel Internals Aging Management Program Plan, dated May 20, 2014. At the time of this inspection, the licensee had not received final approval of their planned aging management program; however, the licensee had submitted the aging management program as committed.

Based on review of the actions implemented related to Commitment 17851, the inspectors determined the licensee had taken appropriate actions to develop their reactor vessel internals aging management program. The inspectors determined that the licensee had met Commitment 5 to develop a reactor vessel internals aging management program as described in a letter to file, Attachment 1.3, Arkansas Nuclear One, Unit 1 (ML070640041). This commitment is closed.

16.1.7 Wall Thinning Inspection Program (17855)

The wall thinning inspection aging management program managed the effects of aging caused by corrosion of the internal surfaces of carbon steel piping and components resulting in the loss of wall thickness.

During the previous inspection, the inspectors determined that the program document did not describe scheduling inspections, basis of line selection, basis for inspection points, and plans for re-inspection. The inspectors had recommended that the system engineer revise the program to include:

(1) details of the system lines included for inspection,

(2) basis for the selecting the examination points,

(3) plans for future inspections, including sample size, and

(4) identification of the wall thickness acceptance criteria.

During this inspection, the inspectors reviewed Program Document SEP-WTI-ANO-001, Wall Thinning Inspection (WTI) Program, Revision 1, and talked with the program manager. The inspectors determined the licensee had included the following in the program document:

• System line descriptions

• Criteria for selecting the examination points

• Future inspections, including sample size

• Acceptance criteria The inspectors determined that the inspections conducted during the last outage for containment piping routed through containment penetrations P-51 and P-59 met the program acceptance criteria.

Based on review of the actions implemented related to Commitment 17855, the inspectors determined the licensee had taken appropriate actions to develop their wall thinning inspection aging management program. The inspectors determined that the licensee had met Commitment 7 to develop a wall thinning inspection aging management program as described in a letter to file, Attachment 1.3, Arkansas Nuclear One, Unit 1 (ML070640041). This commitment is closed.

16.2.3.6 Subsection IWL Inspection Program (17872)

The Subsection IWL inspection aging management program managed the effects of aging caused by loss of material for tendon anchorages, cracking of concrete, and change in material properties of concrete. This program evaluated the quality and structural performance of the reactor building post-tensioning system and concrete components.

During the last inspection, the inspectors concluded, generally, the licensee implemented actions to effectively manage the effects of aging during the period of extended operation with one exception. The licensee issued LR-LAR-2010-00176, Corrective Action 316, to develop a tool to compile inspections, results, and findings that would provide a more effective retrieval of history related to structural components, as part of the structures monitoring program. Since the corrective actions identified in LR-LAR-2010-00176, Corrective Action 316, applied to the Subsection IWL inspection program as well as the structures monitoring program, the inspectors concluded that the licensee had not met this commitment.

During this inspection, the inspectors determined that the licensee had established a database to document deficiencies identified during structural inspections. The database identified the location of the deficiencies by building and room or building, floor and sector. The inspectors observed the structural engineer demonstrate the use of the database and asked plans to enter prior inspections into the database. The licensee had not activated the system and indicated the structural inspections beginning this year would provide the baseline data. Although the licensee had no plans to populate the database with historical inspections, the licensee agreed to populate the database with those deficiencies that required monitoring. The inspectors verified that the licensee continued to track development and population of the database using LR-LAR-2010-00176, Corrective Action 345. Corrective Action 345 of LR-LAR-2010-00176, specified, Identify any previous structural items from the 2010 Maintenance Rule Inspection (Unit 1, 2 and Common) that were noted as required to be tracked for trending purposes.

Based on review of the actions implemented related to Commitment 17872, the inspectors determined the licensee had taken appropriate actions to develop their Subsection IWL inspection aging management program. This commitment is closed.

16.2.3.7 Augmented Inspections Program (19358)

The augmented inspections aging management program managed the effects of aging caused by cracking and loss of material in systems and components that did not require examination in accordance with ASME Section XI. During the previous inspection, the inspectors determined that the licensee established the same controls and performed similar nondestructive examinations as they performed for ASME Section XI components for this commitment with one exception.

During the previous inspection, the inspectors determined the licensee had not performed a one-time inspection of a reactor coolant pump cover because of the potential for high radiation exposure. The licensee had replaced three of the four reactor coolant pump covers and planned to replace the final reactor coolant pump cover in 2019. The licensee revised their commitment to evaluate the effects of aging by taking credit for a reactor coolant pump cover inspection performed at the Davis Besse Nuclear Power Station, Unit 1. The pump vendor supplied identical reactor coolant pumps to Davis Besse and Arkansas Nuclear One, Unit 1. Both facilities had similar operating conditions (temperatures, pressures, etc.) except for chemistry controls. Davis Besse Nuclear Power Station, Unit 1, had demonstrated their chlorides remained well below the threshold that contributed to stress corrosion cracking. Arkansas Nuclear One, Unit 1, had not monitored for the presence of chlorides and fluorides. Consequently, the licensee reviewed historical records related to adding makeup water to the closed cooling water system. The licensee determined that, if they concentrated all accumulated chlorides in the pump cover for the life of the plant, the concentration would have remained below the stress corrosion cracking threshold of 50 ppm (parts per million). In addition to determining the chloride concentration for the life of the plant, the licensee initiated a flaw tolerance evaluation to determine the susceptibility of the pump cover to a flaw propagating. The licensee initiated Commitment 19358 to track completing the flaw tolerance evaluation.

During this inspection, the inspectors verified the licensee had updated their commitment and had completed the flaw tolerance evaluation, which the inspectors reviewed. The flaw tolerance evaluation demonstrated that the weakest link was a circumferential crack and that the maximum ASME code acceptable crack, if it were present, would take 88 years to propagate from the interior welds through the reactor coolant pump cover.

The inspectors identified no concerns with the flaw tolerance evaluation.

Based on review of the actions implemented related to Commitment 19358 related to evaluating the likelihood of a reactor coolant pump casing flaw leaking rather than performing an augmented inspection, the inspectors determined that the licensee demonstrated that they had met their commitment. The inspectors determined that the licensee had met Commitment 8 related to conducting an inspection of their reactor coolant pump casing and an evaluation of the reactor coolant pump cover, as part of their augmented inspection aging management program. This commitment was described in a letter to file, Attachment 1.3, Arkansas Nuclear One, Unit 1 (ML070640041). This commitment is closed.

16.2.13 Maintenance Rule Structural Program (17875)

The Maintenance Rule structural aging management program managed the effects of aging caused by cracking, loss of material, and change in material properties of structures and components. This program included the structures and components identified as being within the scope of license renewal.

During the previous inspection the inspectors identified several issues that prevented closing this commitment. The inspectors questioned:

(1) how the licensee planned to monitor whether changes had occurred between inspections;

(2) means to retrieve the history of structural components (wall, floor, ceiling, support, etc.) or structures as a whole for other than the 5-year planned inspections;

(3) the ability to readily retrieve all available history and trends and to monitor issues identified by other means; and

(4) how the licensee monitored for changes in groundwater to determine whether the water chemistry had changed. The licensee issued LR-LAR-2010-00176, Corrective Action 316, to develop a tool to compile inspections, results, and findings that would provide a more effective retrieval of history related to structural components.

During this inspection, the inspectors determined that the licensee:

• Initiated a procedure change that will require the responsible engineer to make an acceptability evaluation according to the code of record.

• Changed their procedures to explicitly require personnel to search for any corrective action documents related to structural deficiencies prior to performing their inspections.

• Developed a database to capture, track, and trend issues identified during field walkdowns and by other means.

• Established requirements and acceptance criteria to sample ground water for pH, chlorides, and sulfates. The licensee defined a non-aggressive environment as one having pH greater than (>) 5.5, chlorides less than (<) 500 ppm, and sulfates less than (<) 1500 ppm. The licensee prescribed a 5-year monitoring frequency.

Based on review of the actions implemented related to Commitment 17875, the inspectors determined the licensee had taken appropriate actions to develop their Maintenance Rule structural aging management program. This commitment is closed.

16.3.1 Reactor Vessel Neutron Embrittlement (17850)

For the extension of plant service-life from 40 years to 60 years, the licensee identified neutron embrittlement of the beltline region, including pressurized thermal shock and Charpy upper-shelf energy reduction as requiring a time-limited aging analysis.

During the previous inspection, the inspectors determined that the licensee was performing an evaluation to demonstrate that the reactor vessel operating period could be extended from 31.2 to 54 effective full power years, which would allow operation through the end of the period of extended operation. Technical Specification 3.4.3 provided the analysis of the pressure and temperature limitations for reactor operations up to 31 effective full power years. Based on operating history of the plant, the licensee determined that they would achieve 31 effective full power years in 2015. The licensee stated they planned to submit a technical specification amendment request in June 2014 that justified extending the pressure temperature operating limits to 54 effective full power years.

During this inspection, the inspectors determined that the licensee submitted their technical specifications amendment request in Letter 1CAN081403, License Amendment Request - Update the Reactor Coolant Pressure and Temperature and the Low Temperature Overpressure Protection System Limits, dated August 27, 2014.

After submitting this technical specification amendment request, a licensee contractor found some inconsistencies in the original test data related to the orientation of test coupons. Consequently, the licensee withdrew and resubmitted the technical specification amendment request in Letter 1CAN111401, License Amendment Request - Update the Reactor Coolant Pressure and Temperature and the Low Temperature Overpressure Protection System Limits, dated November 21, 2014. The inspectors reviewed the effective full power year calculations and identified no concerns.

Since this technical specification amendment was submitted for approval, the inspectors determined this commitment can be closed since the review and outcome was controlled by another regulatory process.

Based on review of the actions implemented related to Commitment 17850, the inspectors determined the licensee had taken appropriate actions to update their reactor vessel neutron embrittlement time-limited aging analysis. This commitment is closed.

4OA6 Meetings, Including Exit

The inspectors presented the inspection results to Ms. S. Pyle, Manager, Regulatory Assurance, and other members of the licensee staff during an exit meeting conducted on March 19, 2015. The licensee acknowledged the NRC inspection observations. The inspectors retained no proprietary information and verified that no proprietary information was documented in this report.
