The NTTF was tasked with conducting a systematic and methodical review of NRC processes and regulations to determine if the agency should make additional improvements to its regulatory system. On March 12, 2012 the NRC issued a 10CFR50.54(f)

Letter [Ref. 1], which requested information from all licensees to support the NRC staffs evaluation of several of the NTTF recommendations.

To support NTTF Recommendation 2.3, Enclosure 3 to the 50.54(f) Letter requested that all licensees perform seismic walkdowns to gather and report information from the plant related to degraded, non-conforming, or unanalyzed conditions with respect to its current seismic licensing basis.The Electric Power Research Institute (EPRI), with support and direction from the Nuclear Energy Institute (NEI), published industry guidance for conducting and documenting the seismic walkdowns which represented the results of extensive interaction between the NRC, NEI, and other stakeholders.

This industry guidance document, EPRI Report 1025286 [Ref.2], hereafter referred to as "the Guidance", was formally endorsed by the NRC on May 31, 2012. In a letter to the NRC [Ref. 12], Entergy Arkansas Nuclear One (ANO) Unit 2 has committed to using this NRC-endorsed guidance as the basis for conducting and documenting seismic walkdowns for resolution of NTTF Recommendation 2.3: Seismic.The objective of this report is to document the results of the seismic walkdown effort undertaken for resolution of NTTF Recommendation 2.3: Seismic, in accordance with the Guidance, and to provide the information necessary for responding to Enclosure 3 of the 50.54(f) Letter.

SUMMARY

ANO Unit 2 is a pressurized water reactor (PWR) located in Russellville, Arkansas.

The Nuclear Steam Supply System (NSSS) was originally designed by Combustion Engineering.

ANO is a two unit site with unique reactor designs (Unit 1 NSSS being designed and built by Babcock & Wilcox and Bechtel).

ANO Unit 2 began commercial operation in August of 1978, and is currently rated at 1023 MWe power [Ref. 3]. This section summarizes the seismic licensing basis of structures, systems and components (SSCs) at ANO Unit 2 which bound the context of the NTTF 2.3 Seismic Walkdown program.2.1 SAFE SHUTDOWN EARTHQUAKE (SSE)The Safe Shutdown Earthquake (SSE) is the earthquake which produces the maximum vibratory ground motion for which those features necessary to shut down the reactor and maintain it in a safe shutdown condition without undue risk to the health and safety of the public are designed to remain functional.

The safe shutdown earthquake for the ANO Unit 2 site is described by a Housner seismic response spectra anchored at 0.200g peak horizontal ground acceleration and 0.133g peak vertical ground acceleration

[Ref. 3]. The spectra were based on a seismicity evaluation in which a judgment was made estimating the maximum intensity (Modified Mercalli Intensity VII-VIII) that would occur at the site. The SSE is a hypothetical earthquake, which exceeds in intensity any earthquake expected to be felt at the site. All amplified response spectra for Seismic Category 1 structures may be generated from artificial time histories of input motion.These time histories are qualified by producing a ground response spectrum with the time history that must, for each value of damping, acceptably envelope the defined shape of the ground response curve.2.2 DESIGN CODES, STANDARDS, AND METHODS Principle structures, systems, and components (SSCs), which may either serve to prevent accidents or to mitigate their consequences, are designed and are erected in accordance with applicable codes to withstand any deleterious natural phenomena which could be reasonably assumed to occur at the site during the lifetime of the plant. A defense in depth concept is used throughout the industry by providing redundant systems such that a single point of failure does not result in an adverse condition.

Redundancy is provided in the reactor protective and safety feature systems so that no single failure of an active component of the system would prevent action necessary to avoid an unsafe condition.

Seismic Category I SSCs are components (1) whose failure could cause uncontrolled release of radioactivity, or (2) that are essential for safe reactor shutdown and the immediate and long-term operation following a Design Basis Accident.

Engineering Report No. CALC-ANO2-CS-12-00001 Rev. 0 Page 5 of 33 Response Spectra The design basis amplified response spectra for Seismic Category I Structures at ANO Unit 2 were generated from artificial time histories or input motion [Ref. 9]. The time histories are tested for a given level of structural damping thus creating a response spectrum from the time history input. This is done by analyzing a series of single degree of freedom oscillators, each with a specific frequency, and calculating the maximum response of these oscillators using the developed time history as the input. The response spectrum generated is the curve connecting the maximum responses.

This response spectrum developed from the time histories of each value of damping, acceptably envelopes the defined shape of the ground response curve.Equipment and Components The safe-shutdown systems of early nuclear power plants were not designed to current seismic qualification standards and requirements.

In December 1980, the NRC sought assurances that equipment in these older plants could operate during and after an earthquake (Unresolved Safety Issue, USI A-46, Seismic Qualification of Equipment in Nuclear Power Plants). In January 1982, a number of utilities owning older nuclear plants affected by the NRC decision formed the Seismic Qualification Utilities Group (SQUG). The purpose of SQUG was to develop a generic utility group response in support of the resolution of this issue. ANO joined SQUG in 1984. Both SQUG and the NRC have agreed that an acceptable resolution of USI A-46 can be achieved by using seismic experience data as a means of validating installed equipment.

The NRC concluded in Generic Letter 87-02 that the adequacy of certain (generally safe shutdown, active mechanical or electrical) equipment in specific operating nuclear plants (ANO Units 1 and 2 included) be reviewed against seismic criteria not in use when these plants were licensed.

SQUG developed and submitted a Generic Implementation Plan (GIP), Revision 0, dated June 1988, which defined utility actions necessary to close the issue on a plant specific basis. The NRC issued a Generic Safety Evaluation Report (SER) which conditionally approved the GIP and left several incomplete topics for subsequent review. Revision 2 of the GIP (GIP- 2) resolved these topics and incorporated NRC comments.

Subsequently, ANO Unit 2 committed "to the SQUG commitments in GIP-02 as supplemented by the clarifications, interpretations, and exceptions identified in SSER-2 [Supplemental Safety Evaluation Report No. 2] and as clarified by the August 21, 1992, SQUG letter responding to SSER-2 for the resolution of USI A-46 at ANO-1 and ANO-2" [Ref. 10].ANO Unit 2 completed all the NRC requirements (including resolution of all outliers) and received approval of the resolution of the USI A-46 issues in a letter dated February 7, 2000[Ref. 11]. The letter gave permission for the site to revise the licensing basis to include earthquake experience data. This was incorporated into the Units 1 & 2 FSAR.

Engineering Report No. CALC-ANO2-CS-12-00001 Rev. 0 Page 15 of 33 5.0 IPEEE VULNERABILITIES REPORTING During the IPEEE program in response to NRC Generic Letter 88-20 [Ref. 4], plant-specific seismic vulnerabilities were identified.

In this context, "vulnerabilities" refers to conditions found during the IPEEE program related to seismic anomalies, outliers, or other findings.IPEEE Reviewers (see Section 4.4) reviewed the IPEEE final report [Ref. 5] and supporting documentation to identify items that presented a seismic vulnerability according to the IPEEE program. IPEEE Reviewers then reviewed additional plant documentation to identify the eventual resolutions to those seismic vulnerabilities not resolved by the completion of the IPEEE program. I The seismic vulnerabilities identified for ANO Unit 2 during the IPEEE program are reported in Attachment A; a total of 10 seismic vulnerabilities were identified.

For each seismic vulnerability identified, Attachment A includes three pieces of information requested by Enclosure 3 of the 50.54(f) Letter: " a description of the action taken to eliminate or reduce the identified seismic vulnerability;

• whether the configuration management program (CMP) has maintained the IPEEE action (including procedural changes), such that the vulnerability continues to be addressed;" when the resolution actions were completed (per LIR L96-0055).

In Attachment A, the Change Management Program (CMP) column is marked "Yes" when a change to a controlled document was made as a result of the identified IPEEE vulnerability.

The list of IPEEE vulnerabilities provided in Attachment A was used to ensure that some equipment enhanced as a result of the IPEEE program were included in the equipment selected for the NTTF 2.3 Seismic Walkdowns (see Section 6.1.2). Documents describing these equipment enhancements and other modifications initiated by identification of IPEEE vulnerabilities were available and provided to the SWEs during the NTTF 2.3 Seismic Walkdowns.

Engineering Report No. CALC-ANO2-CS-12-00001 Rev. 0 Page 16 of 33 6.0 SEISMIC WALKDOWN EQUIPMENT LIST DEVELOPMENT This section summarizes the process used to select the SSCs that were included in the Seismic Walkdown Equipment List (SWEL) in accordance with Section 3 of the Guidance.

A team of equipment selection personnel with extensive combined knowledge of plant systems and components was selected to develop the SWEL. The SWEL is comprised of two groups of items:* SWEL 1 consists of a sample of equipment required for safe shutdown of the reactor and to maintain containment integrity (i.e., the five safety functions)" SWEL 2 consists of items related to the spent fuel pool The final SWEL is the combination of SWEL 1 and SWEL 2. The development of these two groups is described in the following sections.6.1 ITEMS SUPPORTING THE FIVE SAFETY FUNCTIONS Safe shutdown of the reactor involves four safety functions:

• Reactor reactivity control (RRC)* Reactor coolant pressure control (RCPC)" Reactorcoolant inventory control (RCIC)" Decay heat removal (DHR)Maintaining containment integrity is the fifth safety function:* Containment function (CF)The overall process for developing a sample of equipment to support these five safety functions is summarized in Figure 1-1 of the Guidance.

Figure 1-1 of the Guidance illustrates a screening method for selecting SSCs, starting with all of the SSCs for the plant'and reducing the number based on certain screening criteria referenced in Section 3 of the Guidance.

The list of equipment coming out of Screen #3 and entering Screen #4 is defined as Base List 1. The list of equipment coming out of Screen #4 is the first Seismic Walkdown Equipment List, or SWEL 1. Development of these lists is described separately in the following sections.6.1.1 Base List 1 Based on Figure 1-1 and Section 3 of the Guidance, Base List 1 should represent a set of Seismic Category (SC) I equipment or systems that support the five safety Engineering Report No. CALC-ANO2-CS-12-00001 Rev. 0 Page 17 of 33 functions.

The IPEEE program was intended to address the seismic margin of SSCs associated with each of the five safety functions.

At ANO Unit 2, the EPRI Seismic Margin Assessment (EPRI SMA) method was used to complete the seismic IPEEE program, based on EPRI Report NP-6041 titled "A Methodology for Assessment of Nuclear Power Plant Seismic Margin" [Ref. 8]. Section 3 of the ANO Unit 2 IPEEE report [Ref. 5] describes that an equipment list was developed representing the SSCs necessary for one preferred and one alternate "success path" capable of achieving and maintaining a safe shutdown condition for at least 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> following a SSE event.The equipment list of SSCs from the IPEEE report closely represents components meeting the requirements of Screens #1 through #3 of the Guidance; therefore, the IPEEE equipment list of SSCs [Ref. 5] on the success paths is used as a starting point for the NTTF 2.3 Seismic Walkdown Base List 1. Each component was then checked in the Entergy Component Electronic Database to verify its safety classification, preventative maintenance, environment, etc. Entergy's Electronic Database was searched and plant personnel were consulted to find any additional components that were added or replaced in the past 15 years (since the IPEEE report). The resulting list represents Base List 1.Base List 1 is presented as Table 1 in Attachment B. Base List 1 has 774 total items.6.1.2 SWEL 1 Based on Figure 1-1 and Section 3 of the Guidance, SWEL 1 should represent a diverse population from items on Base List 1 including representative items from a variety of systems within each of the five sample selection attributes.

Additionally, the selection of SWEL 1 items includes consideration of the importance of the contribution to risk for the SSCs. Equipment Selection Personnel (see Table 4-1) developed SWEL 1 using an iterative process. The following paragraphs describe the equipment selection process for the final SWEL 1 and how each of the five sample selection attributes are reflected while also considering risk significance.

In general, preference for inclusion on SWEL 1 was given to items that are accessible and have visible anchorage.

SWEL 1 items are shown in bold on Table 1 in Attachment B.SWEL 1 is presented as Table 2 in Attachment B. SWEL 1 has 94 total items.Variety of Types of Systems Items were selected from Base List 1 ensuring that all of the five safety functions were well represented.

Additionally, components from a variety of frontline and support systems, as defined in Appendix E of the Guidance, were selected.

The system type of each item on SWEL 1 is listed on Table 2 of Attachment B.

Engineering Report No. CALC-ANO2-CS-12-00001 Rev. 0 Page 18 of 33 Major New and Replacement Equipment With assistance from plant operations, Equipment Selection Personnel identified items on Base List 1 that are either major new or replacement equipment installed within the past 15 years, or have been modified or upgraded recently.

These items are designated as such in a column on Base List 1 in Table 1 of Attachment B. No new or replacement equipment meeting the definition of "major" in the Guidance was identified so none were included on SWEL 1.Variety of Equipment Types According to Appendix B of the Guidance, there are 22 classes of mechanical and electrical equipment.

The items on Base List 1 were classified accordingly and the total number of items from each class was determined.

Items were then selected from Base List 1 ensuring that each of the equipment classes was represented on SWEL 1 in approximately equal ratios. The equipment class of each item on SWEL 1 is listed in Table 2 of Attachment B. Note that SWEL 1 does not include components from Classes 12, 13 and 14 since they are not represented on Base List 1. Additionally, minimal Classes 3 and 9 items are represented on Base List 1 and are not reasonably or safely accessible, so they were not included on SWEL 1.Variety of Environments Items were selected from Base List 1 located in a variety of buildings, rooms, and elevations.

These item locations represented environments that were both inside and outside, as well as having high temperature and/or elevated humidity, and also items located within containment.

Items that were part of borated systems were also included.

The location and environment details of each item on SWEL 1 are listed in Table 2 of Attachment B.IPEEE Enhancements With assistance from the IPEEE Reviewers, Equipment Selection Personnel identified items on Base List 1 that were enhanced as a result of seismic vulnerabilities identified during the IPEEE program (see Section 5.0). These items are designated as such in the column designated "IPEEE" on Base List 1 in Table 1 of Attachment B. Several of these items are represented on SWEL 1 (Table 2, Attachment B).Risk Siqnificance Information from the plant Probabilistic Risk Analysis (PRA) model and the Maintenance Rule Program implementation documentation were used to determine whether items were risk significant.

The components were ranked using the RAW (Risk Achievement Worth). RAW represents the factor by which the Core Damage Frequency (CDF) would increase if the component is assumed to fail with certainty.

Engineering Report No. CALC-ANO2-CS-12-00001 Rev. 0 Page 19 of 33 When it came to items with similar sample selection attributes, the items with higher risk significance were chosen.6.2 SPENT FUEL POOL ITEMS The overall process for developing a sample of SSCs associated with the spent fuel pool (SFP) is similar to that of the screening process for SWEL 1 and is illustrated in Figure 1-2 of the Guidance.

The list of items coming out of Screen #2 and entering Screen #3 is defined as Base List 2. The items coming out of Screen #4 are the items that could potentially cause the SFP to drain rapidly. The items coming out of either Screen #3 or Screen #4 are the second Seismic Walkdown Equipment List, or SWEL 2. Development of these lists is described separately in the following sections.6.2.1 Base List 2 Based on Figure 1-2 and Section 3 of the Guidance, Base List 2 should represent the Seismic Category I equipment or systems associated with the SFP. To develop Base List 2, Equipment Selection Personnel (see Table 4-1) reviewed plant design, licensing basis documentation, and plant drawings for the SFP and its associated cooling system. After a review of all associated documentation and extensive searches through the Entergy Component Electronic Database, only one item was identified, specifically dealing with Makeup Water for the SFP. Having minimal items is expected as ANO's spent fuel pool cooling is a non-safety related system as shown in the Spent Fuel Pool Upper Level Document [Ref. 13]. Having a non-safety related Spent Fuel Pooling Cooling system is typical of plants with similar age to ANO.Base List 2 is presented as Table 3 in Attachment B. Base List 2 has five total items.6.2.2 Rapid Drain-Down Rapid drain-down is defined as unintentionally lowering the water level to the top of the fuel assemblies within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> after an earthquake

[Ref. 2]. Consistent with the Guidance, the Equipment Selection Personnel (see Section 4.1) identified SSCs that could cause the SFP to drain rapidly by first reviewing the SFP documentation to identify penetrations below about 10 ft above the top of the fuel assemblies

[Ref. 2].The review found that no such SFP penetrations exist below the critical threshold of 10 ft above the top of the fuel assemblies.

Additionally, anti-siphon devices are installed on all piping coming into the SFP. Therefore, there is no potential for rapid drain-down of the SFP following a seismic event. Consequently, there are no rapid drain-down items on SWEL 2.

Engineering Report No. CALC-ANO2-CS-12-00001 Rev. 0 Page 20 of 33 6.2.3 SWEL 2 Based on Figure 1-2 and Section 3 of the Guidance, SWEL 2 should be a broad population of items on Base List 2 including representative items from some of the variations within each of sample selection attributes (using a sample process similar to SWEL 1), plus each item that could potentially cause rapid-drain down of the SFP.Considering that Base List 2 only has five items, the SWEL 2 selection represents the majority of the Base List 2.SWEL 2 is presented as Table 4 in Attachment B. SWEL 2 has four total-items.

6.3 DEFERRED

INACCESSIBLE ITEMS ON SWEL Each item on the SWEL shall be walked down as part of the NTTF 2.3 Seismic Walkdown program. In order to perform the seismic walkdowns of these items, it is necessary to have access to them and to be able to view their anchorage.

A panel located inside the 2K-4A Emergency Diesel Generator Room was not fully accessible because it is an energized electrical panel that could only be fully opened during a Diesel Outage. ANO Unit 2 did not have a Diesel Outage during the original walkdown period, so opening this panel could present a plant risk. In accordance with Enclosure 3, this item is considered "deferred" and a schedule for completion has been developed.

Completion of the walkdown of the item in the 2K-4A Emergency Diesel Room has been deferred until the next Diesel Outage in December of 2012. An updated submittal report incorporating this deferred walkdown will be provided by September 30, 2013.The deferred item is summarized in the table below. The reason for deferral is identified as ACC, indicating that the item is inaccessible.

A total of 1 item is deferred.Table 6-1: Deferred Item Equipment ID Description Location Reason DIESEL GEN NO 1 LOCAL RAB EL 369 ACC CONTROL & EXCITE PANEL ROOM 2093 Engineering Report No. CALC-ANO2-CS-12-00001 Rev. 0 Page 21 of 33 7.0 SEISMIC WALKDOWNS AND AREA WALK-BYS The NTTF 2.3 Seismic Walkdown program, conducted in accordance with the Guidance, involves two primary walkdown activities:

Seismic Walkdowns and Area Walk-Bys.

These activities were conducted at ANO Unit 2 by pairs of trained and qualified Seismic Walkdown Engineers (SWEs) (see Table 4-1). A total of nine SWEs were used to perform the walkdowns.

The teams periodically rotated personnel to cross-check consistency between the SWEs and to ensure that each engineer was able to share their personal experience and learn from the experience of their team member.The seismic walkdowns and area walk-bys were conducted over the course of 3 weeks during September and October of 2012. Each morning, a pre-job brief was conducted with all personnel involved.

This pre-job brief was used to outline the components and areas that would be walked down that day; ensure consistency between the teams; reinforce expectations; identify potential personnel safety issues specific to that day; identify any changes to plant configuration including plant risk; and allow team members to ask questions and share lessons learned in the field. SWEs brought cameras and tape measures on each walkdown; and brought flashlights, mirrors, and a pole for the camera on an as-needed basis.7.1 SEISMIC WALKDOWNS Seismic walkdowns were performed in accordance with Section 4 of the Guidance for all items on the SWEL (SWEL 1 plus SWEL 2), except for those determined to be inaccessible and were deferred (see Table 6-1). In order to document the results of the walkdown, a Seismic Walkdown Checklist (SWC) with the same content as that included in Appendix C of the Guidance was created for each item. Additionally, photographs were taken of each item and included on the corresponding SWC.Preliminary walkdowns were performed to identify inaccessible items. Items that were identified to be inaccessible on this walkdown were swapped out with items that were accessible and met the same selection criteria.

Prior to performance of the walkdowns, documentation packages were developed that contained the SWC and other pertinent information including the location drawings, response spectra information, previous IPEEE and SQUG/A-46 seismic walkdown documentation, and anchorage drawings where applicable.

The SWE teams carried all of the documentation packages into the plant during the seismic walkdowns.

Walkdown inspections focused on anchorages and seismic spatial interactions, but also included inspections for other potentially adverse seismic conditions.

Anchorage, in all cases, was considered to specifically mean anchorage of the component to the structure.

This definition included anchor bolts to concrete walls or floors, structural bolts to structural steel Engineering Report No. CALC-ANO2-CS-12-00001 Rev. 0 Page 22 of 33 and welds to structural steel or embedded plates. The walkdown team visually inspected welds for surface anomalies/defects such as cracks and corrosion in the weld and base metal. Other connections, such as flange bolts on in-line components were not considered as equipment anchorage because it is outside the scope of the Guidance.

These bolts and connections were evaluated by the SWEs and any potential adverse seismic concerns were documented under "other adverse seismic conditions" rather than under "anchorage." By this methodology, components without attachments to the structure are not considered to have anchorage.

Nevertheless, the attachment of these components to other equipment was evaluated and inspected for potentially adverse seismic conditions.

Cabinets/panels on the SWEL that could be inspected without presenting safety or operational hazards were opened during the walkdown.

This allowed visual observation of internal anchorage to the structure (where present), as well as inspection for other adverse seismic conditions related to internal components (if it could be observed without more than minimally breaking the plane of the equipment opening).

Note that minimally breaking the plane did not present any additional value for observing any anchorage or other seismic conditions and given the additional personnel and plant risk, the plane was not broken.In addition to the general inspection requirements, at least 50% of the SWEL items with anchorage must have verification that the anchorage configuration was consistent with plant documentation.

Of the 98 SWEL items, 56 were considered to have anchorage (i.e., removing in-line/line-mounted components).

Of these 56 anchored components, 31 included anchorage configuration verification during walkdowns, which is greater than 50%. When anchorage configuration verification was conducted, the specific plant documentation used for comparison to the observed conditions was referenced on the SWC, and was included in the walkdown package brought into the field.The results of the Seismic Walkdowns of each item of equipment on the SWEL (SWEL 1 plus SWEL 2) are documented on separate Seismic Walkdown Checklists (SWCs), which are included in Attachment C. A total of 105 SWCs are attached; 97 have a completion status marked "Y", 1 has a completion status marked "N", and 7 are blank. SWCs that are blank represent SWCs that were not used for a SWEL number. SWCs that are marked "N" are considered incomplete because an inspection could not be fully performed at the time of the walkdowns.

The inspection could not be performed because the cabinet/panel could not be opened completely during the walkdown period. As seen in Attachment C, 105 completed SWCs represent the completed walkdowns of each SWEL item.7.2 AREA WALK-BYS Seismic area walk-bys were performed in accordance with Section 4 of the Guidance for all plant areas containing items on the SWEL (SWEL 1 plus SWEL 2). A separate Area Walk-By Engineering Report No. CALC-ANO2-CS-12-00001 Rev. 0 Page 23 of 33 Checklist (AWC) with the same content as that included in Appendix C of the Guidance was used to document the results of each area walk-by performed.

Exactly like the SWC, photographs taken of each area, and included on the corresponding AWC.Area walk-bys were conducted once for plant areas containing more than one SWEL item. In cases where the room, or area, containing a component was very large, the area encompassed by the area walk-by was limited to a radius of approximately 35 ft around the subject equipment.

The area included in the area walk-by is described on the respective AWC. Since some areas contained more than one SWEL item, there are fewer total AWCs than SWCs. A total of 51 area walk-bys was necessary to cover all plant areas containing at least one SWEL item.The results of the Area Walk-Bys in areas of the plant near the equipment on the SWEL are documented on separate Area Walk-By Checklists (AWCs), which are included in Attachment D. A total of 51 AWCs are attached, which represents all of the areas containing a SWEL item.The potentially adverse seismic conditions identified by the Seismic Walkdowns and Area Walk-Bys are described in Attachment E. For each potentially adverse condition identified, Attachment E also describes how the condition has been addressed and its current status.

Engineering Report No. CALC-ANO2-CS-12-00001 Rev. 0 Page 24 of 33 8.0 LICENSING BASIS EVALUATIONS During the course of the seismic walkdowns and area walk-bys, the objective of the SWE teams was to identify existing degraded, non-conforming, or unanalyzed plant conditions with respect to its current seismic licensing basis. The following sections summarize the process used to handle conditions that were identified, which conditions were found, and how they were treated for eventual resolution.

Potentially adverse seismic conditions identified during the Seismic Walkdowns and Area Walk-Bys are summarized in Attachment E.CONDITION IDENTIFICATION When an unusual condition was observed by a SWE team in the field, the condition was noted on the SWC or AWC form and briefly discussed between the two SWEs to agree upon whether it was a potentially adverse seismic condition.

The initial conclusions were based on conservative engineering judgment and by the training required for SWE qualification.

For conditions that were reasonably judged as insignificant to seismic response, a disposition was included on the SWC or AWC checklist and the appropriate question was marked "Y", indicating that no associated potentially adverse seismic condition was observed.

Unusual or uncertain conditions were reported to site personnel for further resolution through the Corrective Action Program (CAP) (see Section 8.2.2). A total of 4 seismically insignificant conditions were identified and entered into the CAP. These conditions were related to housekeeping (2), routine maintenance (1) and minor maintenance (1).For conditions that were judged to be potentially significant to seismic response, the condition was photographed, and the appropriate question on the SWC or AWC was marked "N", indicating that a potentially adverse seismic condition was observed.

The condition was immediately reported to site personnel for further resolution (see Section 8.2) and it was documented for reporting in Attachment E. A total of 19 potentially adverse seismic conditions were identified.

Identified conditions were related to overhead lighting (11), non-conforming anchorage (4), corrosion (2), and housekeeping (1).CONDITION RESOLUTION Conditions observed during the seismic walkdowns and area walk-bys that were determined to be potentially adverse seismic conditions are summarized in Attachment E, including how each condition has been addressed and its current status. Each potentially adverse seismic condition was addressed by being entered into the CAP directly.Unusual conditions that were not seismically significant were still entered into the CAP.Further resolution of these conditions is not tracked or reported as part of the NTTF 2.3 Engineering Report No. CALC-ANO2-CS-12-00001 Rev. 0 Page 25 of 33 Seismic Walkdown program, except by noting the CR numbers generated on the applicable SWCs and AWCs.8.1 LICENSING BASIS EVALUATIONS (LBE)Section 5 of the Guidance describes that potentially adverse seismic conditions identified as part of the NTTF 2.3 Seismic Walkdown program may be evaluated by comparing them to the current licensing basis of the plant as it relates to the seismic adequacy of the equipment in question.

If the identified condition is consistent with existing seismic documentation for that item, then no further action is required.

If the identified condition cannot distinctly be shown to be consistent with existing seismic documentation, or no seismic documentation exists, then the condition is entered into the CAP.Based on the type of conditions found, and with ANO's low threshold for identifying conditions and entering them directly into the CAP, all identified potentially adverse seismic conditions were entered directly into the CAP; thus no LBEs were performed.

8.2 CORRECTIVE

ACTION PROGRAM ENTRIES Conditions identified during the seismic walkdowns and area walk-bys that required further resolution were entered into the plant's CAP. These were reviewed further in accordance with the plant's existing processes for an eventual disposition.

Conditions entered into the CAP included two types of unusual conditions identified:

• Seismically insignificant unusual conditions

• Potentially adverse seismic condition that bypasses a LBE A total of 23 Condition Reports (CRs) were generated from the CAP as a result of the NTTF 2.3 Seismic Walkdown program. Of those generated, 4 were from seismically insignificant unusual conditions.

A total of 19 CRs were written for potentially adverse seismic conditions that were identified.

CRs initiated for potentially adverse seismic conditions were evaluated using the operability/functionality determination process in the CAP. Since identification, all identified potentially adverse seismic conditions have either been repaired or determined to not be an adverse seismic condition.

The CR numbers, current status, and resolution (where applicable and available) are summarized for these potentially adverse seismic conditions in Attachment E.8.3 PLANT CHANGES The CAP entries (CRs) generated by the NTTF 2.3 Seismic Walkdown program are being resolved in accordance with the plant CAP process, including operability evaluations, extent of condition evaluations, and root cause analysis (where applicable).

Initial evaluations Engineering Report No. CALC-ANO2-CS-12-00001 Rev. 0 Page 26 of 33 indicate that no immediate plant changes are necessary beyond minor maintenance and routine housekeeping.

Final and complete resolutions of the CRs for seismically insignificant unusual conditions and potentially adverse seismic conditions can determine if future modifications to the plant are required.

While no immediate plant modifications beyond minor maintenance or routine housekeeping have been identified as a result of the seismic walkdowns and walk-bys, various cases were found where degraded conditions or housekeeping issues were immediately addressed.

Current status and resolutions (where applicable and available) for CRs related to potentially adverse seismic conditions are provided in Attachment E. As a result of the Seismic Walkdown program, no condition challenged the operability of any SSCs.

Engineering Report No. CALC-ANO2-CS-12-00001 Rev. 0 Page 27 of 33 9.0 PEER REVIEW 9.1 PEER REVIEW PROCESS The peer review for the NTTF Recommendation

2.3 Seismic

Walkdowns was performed in accordance with Section 6 of the Guidance.

The peer review included an evaluation of the following activities:

• review of the selection of the structures, systems, and components, (SSCs) that are included in the Seismic Walkdown Equipment List (SWEL);* review of a sample of the checklists prepared for the Seismic Walkdowns and area walk-bys;* review of licensing basis evaluations and decisions for entering the potentially adverse conditions in to the plant's Corrective Action Plan (CAP); and* review of the final submittal report.At least two members of the peer review team (see Table 4-2) were involved in the peer review of each activity.

The team member with the most relevant knowledge and experience took the lead for particular peer review activities.

A designated overall Peer Review Team Leader provided oversight related to the process and technical aspects of the peer review, paying special attention to the interface between peer review activities involving different members of the peer review team.9.2 PEER REVIEW RESULTS

SUMMARY

The following sections summarize the process and results of each peer review activity.9.2.1 Seismic Walkdowns Equipment List Development Peer review of the selection of SSCs for SWEL development was conducted by two peer reviewers.

The lead reviewer for this peer review activity has knowledge and experience related to nuclear power plant design, operations, documentation, and SSCs; the other reviewer has extensive knowledge of the plant and was an integral part of the equipment selection process for ANO Unit 2. The peer review of the SWEL was conducted prior to the start of the seismic walkdowns, and was performed as follows: The draft SWEL (SWEL 1 + SWEL 2) was provided to the peer reviewers, along with the corresponding base lists (Base List 1, Base List 2, and SFP rapid drain-down list) and a written explanation of the equipment selection process was given (see Section 6.0).

Engineering Report No. CALC-ANO2-CS-12-00001 Rev. 0 Page 28 of 33* Each peer reviewer independently reviewed the equipment selection process, and resulting SWEL, in terms of the equipment selection process presented in Section 3 of the Guidance." The peer reviewers discussed their findings and generated a consolidated list of comments.

General comments on the overall list, and how it represents adequate diversity, were documented on a peer review checklist based on Appendix F of the Guidance.* Comments were provided to the Equipment Selection Personnel (see Table 4-1) which discussed process clarifications and suggested revisions." The final SWEL was provided to the peer reviewers to confirm acceptable resolution of all comments.All of the peer review comments were addressed by the Equipment Selection Personnel, and the peer review team concluded that all comments were adequately addressed.

The primary result of the peer review activities was that the Equipment Selection Personnel modified the documentation of their selection methodology.

This provided further clarification of their rationale for selecting certain items, explaining how they were satisfying the sample selection criteria defined in Section 6.1.2. The peer review team concluded that these modifications would be beneficial to provide transparency and justification for the adequacy of the SWEL, and it resolved their specific questions about potential deficiencies.

During the process of conducting the walkdowns, SWE teams encountered a small number of components that were not accessible and therefore removed from the SWEL. In most cases, equivalent items that were determined to be accessible were added in their place and were walked down instead (see Section 7.0). The peer review team reviewed all changes made to the SWEL, and determined that these changes had no impact on the adequacy and integrity of the SWEL, with respect to the Section 3 of the Guidance.Upon completion of the SWEL peer review activities described, the peer review team concluded that the Equipment Selection Personnel developed a SWEL that adequately reflects the selection and screening process outlined in the Guidance.

The peer reviewers confirmed that all SSCs in the SWEL are Seismic Category I components that do not undergo regular inspections, and represent a diverse blend of different component types from critical systems and safety-related functions.

The components on the list represent adequate risk significance.

Additionally, SFP items were appropriately addressed.

Specific examples of how the SWEL adequately represents Engineering Report No. CALC-ANO2-CS-12-00001 Rev. 0 Page 29 of 33 the sample selection attributes described in Section 3 of the Guidance are provided on the peer review checklist included as Attachment G.The peer review of the SWEL is provided in Attachment G. Peer review comments are documented in Attachment H.9.2.2 Seismic Walkdowns and Area Walk-Bys Peer review of the seismic walkdowns and area walk-bys was also conducted by two peer reviewers, both of whom are qualified SWEs and have broad knowledge of seismic engineering applied to nuclear power plants. One of the peer reviewers participated in the seismic walkdown program for a different utility, and the other is engaged with the industry team which developed the Guidance.

The peer reviews were performed at ANO Unit 2 concurrent with the conduct of walkdowns, at approximately 50% completion.

One peer reviewer was physically present at ANO to observe the walkdown process first-hand.

The peer review was performed as follows:* The peer review team reviewed the walkdown packages (including checklists, photos, referenced drawings, etc.) for SWEL items already completed to ensure that the checklists had been completed in accordance with the Guidance.

A total of 12 SWC and 5 AWC forms were reviewed, each representing approximately 10% of their respective totals. The peer review for ANO Unit 2 was conducted at the same time as the ANO Unit I peer review. Considering the Unit 1 peer review was successful, fewer items were reviewed, while still meeting the requirements provided in the Guidance.

In the context of the Guidance, the peer review team considered the number of walkdown packages reviewed to be appropriate.

The packages reviewed represent a variety of equipment types in various plant areas. Specific SWC forms reviewed are SWEL1-008, SWELl-010, SWELI-028, SWEL1-029, SWEL1-030, SWELl-031, SWELl -044, SWEL1-049, SWELl -056, SWEL1-057, SWELI-064, and SWEL1-080.

Specific AWC forms reviewed are AWC-013, AWC-028, AWC-029, AWC-030, and AWC-031.* While reviewing the walkdown packages, the peer reviewers conducted informal interviews with the SWEs, and asked clarifying questions to verify that they were conducting walkdowns and area walk-bys in accordance with the Guidance.* The peer reviewer on-site held a meeting with all SWEs to provide feedback regarding the walkdown and walk-by packages reviewed, the informal Engineering Report No. CALC-ANO2-CS-12-00001 Rev. 0 Page 30 of 33 interviews that were conducted, and to discuss potential modifications to the documentation packages in the context of the Guidance.* The peer reviewer on-site participated in the pre-job brief as well as accompanied each SWE team into the field and observed them performing a walkdown of a SWEL component and its associated area walk-by. During these observations, the peer reviewer asked clarifying questions to verify that the walkdown and walk-by process being used was in accordance with the Guidance.

The items walked down under the observation of a peer reviewer are SWELI-014, SWELl-029 and SWELl-030.

The associated area walk-bys performed under the observation of a peer reviewer are AWC-002, AWC-008 and AWC-030.* The peer reviewer on-site held a meeting with the SWE teams to provide feedback over the walkdown and walk-by observations, and to discuss how lessons learned from review of the walkdown packages had been incorporated into the walkdown process.As a result of the peer review activities, the SWE teams modified their documentation process for filling out checklists.

For example, SWE teams began to include additional clarifying details related to checklist questions marked "N/A" and for conditions that were observed but judged to be insignificant.

The peer review team felt that these modifications would be beneficial for future reviews of checklists that are incorporated into the final report. These modifications were recommended following review of the walkdown and area walk-by packages, so the observation of walkdowns and area walk-bys allowed the SWEs to demonstrate that they understood the recommendations and have been incorporating them into the walkdown and area walk-by process. Previously completed checklists were revised by the SWEs to reflect lessons learned from the peer review process.Based on completion of the walkdown and walk-by peer review activities described, the peer review team concluded that the SWE teams are familiar with and followed the process for conducting seismic walkdowns and area walk-bys in accordance with the Guidance.

The SWE teams adequately demonstrated their ability to identify potentially adverse seismic conditions such as adverse anchorage, adverse spatial interaction, and other adverse conditions related to anchorage, and perform anchorage configuration verifications, where applicable.

The SWEs also demonstrated the ability to identify seismically-induced flooding interactions and seismically-induced fire interactions such as the examples described in Section 4 of the Guidance.

The SWEs demonstrated appropriate use of self-checks, peer checks, and pre-job briefs. They Engineering Report No. CALC-ANO2-CS-12-00001 Rev. 0 Page 31 of 33 discussed their observations with a questioning attitude, and documented the results of the seismic walkdowns and area walk-bys on appropriate checklists.

Peer review comments are documented in Attachment H.9.2.3 Licensing Basis Evaluations No Licensing Basis Evaluations were performed for ANO Unit 2. Therefore, a peer review was not necessary for Licensing Basis Evaluations.

9.2.4 Submittal

Report The peer review team was provided with a draft of this submittal report for peer review.The peer review team verified that the submittal report met the objectives and requirements of Enclosure 3 to the 50.54(f) Letter, and documented the NTTF 2.3 Seismic Walkdown program performed in accordance with the Guidance.

The peer review team provided the results of review activities to the SWE team for consideration.

The SWE team satisfactorily resolved all peer review comments into the final version of the submittal report. The signature of the Peer Review Team Leader provides documentation that all elements of the peer review were completed in accordance with Section 6 of the Guidance.
