Executive Summary As a result of the Fukushima Daiichi Nuclear Power Plant accident, the U.S. Nuclear Regulatory Commission (NRC) required all US nuclear power plants to perform seismic walkdowns to identify and address degraded, non-conforming or unanalyzed conditions and to verify the current plant configuration with the current seismic licensing basis.The NRC Near-Term Task Force (NTTF) issued a report (Reference

1) that made a series of recommendations.

Subsequently, the NRC issued a 50.54(f) Letter (Reference

2) that requests information to assure that these recommendations are addressed by all U.S. nuclear power plants. This report provides guidance for conducting a seismic walkdown as required in the 50.54(f) Letter, Enclosure 3, Recommendation 2.3: Seismic.In support of conducting the NTTF-2.3 Seismic Walkdowns, the Electrical Power Research Institute (EPRI) issued a report entitled Seismic Walkdown Guidance for Resolution of Fukushima Near-Term Task Force Recommendation 2.3: Seismic (Reference 3 -hereafter "EPRI Seismic Walkdown Guidance")

to provide instruction for uniform seismic walkdowns of all U.S. nuclear power plants. This document also includes guidance for reporting the findings of the required walkdowns. At Unit 1 of the Sequoyah Nuclear Power Plant, a total of 120 general Seismic Category I equipment items were selected from the original Individual Plant Examination for External Events (IPEEE) Safe Shutdown Equipment List (SSEL) to fulfill the requirements of the NTTF-2.3 Seismic Walkdowns. The selected items were located in various environments and included many different types of equipment from multiple safety systems. A total of 46 areas were included for area walk-bys. The equipment walkdowns and area walk-bys were performed by two teams, each consisting of two seismic engineers and operations personnel, between July 13, 2012 and August 10, 2012.Of the 120 equipment items in the Seismic Walkdown Equipment List (SWEL), 110 were completed during the walkdown phase. Twelve potentially adverse seismic conditions were found and addressed through the TVA Corrective Action Program.There are ten remaining items of equipment that were inaccessible at 100% power due to physical limitations or excessive safety hazards. These equipment walkdowns will be performed during the next Sequoyah Unit 1 refueling outage, scheduled for October through November 2013.4 NTTF Recommendation 2.3: Seismic Response Report Sequoyah Unit 1 2. Seismic Licensing Basis The seismic licensing basis for the Sequoyah Nuclear Power Plant is derived from Reference 4 -Sequoyah Nuclear Plant Living Final Safety Analysis Report Amendment 24.2.1. General Plant Description The Sequoyah Nuclear Power Plant site is located near the geographical center of Hamilton County, Tennessee, on a peninsula on the western shore of Chickamauga Lake at Tennessee River mile (TRM) 484.5. The Sequoyah site is approximately 7.5 miles northeast of the nearest city limit of Chattanooga, Tennessee, 14 miles west-northwest of Cleveland, Tennessee, and approximately 31 miles south-southwest of TVA's Watts Bar Nuclear Power Plant. The plant has been designed, built, and is operated by TVA and contains two identical units. Each of the two units employs a Pressurized Water Reactor Nuclear Steam Supply System with four coolant loops, furnished by Westinghouse Electric Corporation. Unit 1 began commercial operation in July 1, 1981.2.2. Ground Response Spectra The seismic design basis for Sequoyah Nuclear Power Plant is the 0.18g horizontal peak ground acceleration represented by the modified Housner-shape spectrum for Safe Shutdown Earthquake (SSE). Operating Basis Earthquake (OBE) is one-half of SSE ground acceleration. Vertical ground acceleration is two-thirds of the horizontal ground acceleration. Figure 1 illustrates the relationship between the 5% damped minimum design response spectra and the actual site seismic design response spectra for the SSE used in the design of rock-supported structures. 5 NTTF Recommendation 2.3: Seismic Response Report Sequoyah Unit 1 W'10%410eý-W --I 'kZ14 14"N vzzrf'j-V ACr' VN'-XC1 vi*,V-k Zel Im --,40 20 0 0.0.06 0.04.'01.04 f F~ 4x A \1XA)1~?VAY LN A N7!X(\ i~tWX:1 A A' ~.

Equipment and Systems Nuclear Steam Supply System (NSSS) components and equipment supplied by Westinghouse have been qualified in accordance with the applicable seismic qualification requirements. Seismic qualification requirements for Seismic Category I systems and components are consistent with Institute of Electrical and Electronics Engineers (IEEE) Standard 344-1971. Seismic Category I mechanical equipment has been qualified in accordance with the applicable seismic qualification requirements contained in Reference 4.Class I equipment and safety related piping were designed such that stress and deformation behavior were maintained within the allowable limits when subjected to normal operating conditions combined with the seismic effects resulting from the response to the OBE. In addition, the stresses that resulted from normal loads combined with the response to the SSE were limited so that no loss of function occurred, and the capability of making a safe and orderly plant shutdown was maintained. The allowable limits are defined in appropriate design standards including: o American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code, 1986 o American National Standards Institute (ANSI) Code for Pressure Piping ANSI B31.1.0, Power Piping, 1967 0 AISC Specification for the Design, Fabrication and Erection of Structural Steel for Buildings, February 12, 1969 8 NTTF Recommendation 2.3: Seismic Response Report Sequoyah Unit 1 3.

This course was 9 NTTF Recommendation 2.3: Seismic Response Report Sequoyah Unit 1 held at MPR Associates, Inc. in Alexandria, VA. It is noted in Frequently Asked Questions on Seismic Walkdown Guidance, Reference 8, that completion of this course qualifies those in attendance to facilitate presentation of course material in subsequent training sessions for others. Mr. Summers, Mr. York, and Mr. Edgar completed the course in a subsequent training session held at TVA's office complex in Chattanooga, TN. This subsequent training session was conducted by Steve Eder and John Dizon, subject-matter experts (personnel qualifications outlined in Section 3.5 below) who also completed the EPRI course in Virginia.In addition to the walkdown training course developed by EPRI, all seismic walkdown engineers attended Sequoyah site-specific training before the walkdown process began.John Dizon facilitated the site-specific training by presenting explanations of licensing basis documents, IPEEE results and associated outliers, and seismically-related issues historically experienced at Sequoyah Nuclear Plant. The site-specific training also provided overviews of established seismic programs, which address the following: " Equipment anchorage and reaction load validation" Seismic category I(L) piping hazards (11/I failure, falling, and spray issues)* Distribution and suspended systems* Concrete / masonry wall and embedded plates* Structural platforms All training records can be found in Appendix A.3.3. Licensing Basis Reviewers The personnel who performed the licensing basis reviews:* Karen Carboni, Site Civil Engineer at Sequoyah with over seven years of experience in seismic equipment qualification and piping seismic analysis.* Glynna Wilson, Site Civil Engineer at Sequoyah with over four years of experience in structural analysis, including seismic equipment qualification. 3.4. IPEEE Vulnerability Incorporation Personnel I The personnel who incorporated IPEEE vulnerabilities are:* Joshua Best, Project Mechanical Engineer with 5 years engineering experience, including 4 years in the nuclear power industry." Phillip York, (credentials outlined in Section 3.1 above)To ensure that IPEEE vulnerabilities were given proper consideration in the development of the equipment sample, the individuals listed above reviewed the IPEEE submittal report and the subsequent Request for Additional Information (RAI), identified 10 NTTF Recommendation 2.3: Seismic Response Report Sequoyah Unit 1 appropriate outliers, and extracted the SSEL which became the basis for SWEL development. The results of this process were reviewed by the Peer Review Team members, whose applicable IPEEE-related experience is outlined in Section 3.5 below.3.5. Peer Review Team The personnel involved in the peer review process are:* John Dizon, Professional Engineer with over 30 years of experience in the field of civil and structural engineering, earthquake engineering, risk assessment and project management.

• Steve Eder, Professional Engineer with over 30 years of experience in the field of civil and structural engineering, project management, seismic engineering, and risk management John Dizon is the Peer Review Team Leader. Through years of experience assisting TVA at SQN (since 1986), Mr. Dizon and Mr. Eder are familiar with the SQN plant design, plant operations, plant documentation, and associated SSCs. Past experience at SQN includes seismic design criteria development, verification of Seismic Category I(L) piping, and assistance on seismic qualification of cable trays, conduit, and other miscellaneous equipment and replacement parts. Mr. Dizon and Eder have supported TVA seismic qualification projects not only at SQN, but also at BFN, BLN, and WBN.Mr. Dizon and Mr. Eder provided calculation CDQ-000-999-2012-000034 (Reference 9), which revised seismic HCLPF capacities for the governing SSCs from the seismic IPEEE, for control motion re-defined at rock outcrop.11 NTTF Recommendation 2.3: Seismic Response Report Sequoyah Unit 1 4. Selection of Structures, Systems and Components The selection of SSCs for the Recommendation 2.3 Seismic walkdowns followed the guidelines provided in the EPRI Seismic Walkdown Guidance.

The combined SWEL for Sequoyah Unit 1, which consists of 120 items of equipment, adequately addresses all required selection criteria. These criteria include a distribution of environments, systems, safety functions, and classes of equipment. The SWEL 1 and 2 selection process is outlined in the following sections.4.1. SWEL 1 Selection The SWEL 1 selection screening process was performed in accordance with the EPRI Seismic Walkdown Guidance. A schematic of the screening process taken directly from the EPRI Seismic Walkdown Guidance is shown below -Ab Figure 2: SWEL 1 Selection Process Screens #1 through #3 The.development of SWEL 1 began with the SSEL that was developed as part of the IPEEE implementation at Sequoyah, found in Reference 5 -Seismic Capability 12 NTTF Recommendation 2.3: Seismic Response Report Sequoyah Unit 1 Walkdown for IPEEE. This list fulfills the requirements of Screens #1 through #3 shown above.It should be noted that an additional safety function "0 -Support Function" was added to the five safety functions listed in the EPRI guidance document to categorize equipment that does not perform one particular safety function but does support all five safety functions. The expanded safety function list is shown below: 0. Support function 1. Reactor reactivity control 2. Reactor coolant pressure control 3. Reactor coolant inventory control 4. Decay heat removal 5. Containment function The SSEL with assigned safety functions are presented in Appendix B as Base List 1.Screen #4 From Base List 1, equipment meeting three of the five screen requirements (system, equipment type, and environment) was identified. The systems and equipment types were chosen based on the criteria provided in the EPRI Seismic Walkdown Guidance.The equipment environments selected for screen #4, which were not explicitly defined by EPRI, are listed below:* Control Building* Auxiliary Building* Reactor Building* Diesel Generator Building* Emergency Raw Cooling Water Pump Station.It should be noted that some of the equipment classes listed in the EPRI Seismic Walkdown Guidance were not represented in the original IPEEE SSEL, and therefore are not present in Base List 1. To ensure that all equipment classes identified in the EPRI Seismic Walkdown Guidance were represented in SWEL 1, the scope of selection was expanded to include SSCs which are not in the IPEEE SSEL but meet all screening criteria.For the new or replacement equipment requirement, the walkdown team consulted with plant operations to identify system enhancements resulting in new or replaced equipment.

SWEL 2 Selection The SWEL 2 selection screening process was performed in accordance with the EPRI Seismic Walkdown Guidance.

A schematic of the screening process taken directly from the EPRI Seismic Walkdown Guidance is shown below: 17 NTTF Recommendation 2.3: Seismic Response Report Sequoyah Unit 1 Figure 3: SWEL 2 Selection Process Screens #1 through #2 The Master Equipment List for Sequoyah Nuclear Plant was utilized to retrieve a complete list of all Seismic Category 1 spent fuel pool systems and equipment. This list is presented in Appendix C as Base List 2.Screen #3 The Spent Fuel Pool System at Sequoyah was limited to a single environment and a single system with no new or replacement equipment since the IPEEE analysis.Therefore the only screen #3 requirement that could be met was that of varying equipment type. Two items of differing equipment types were selected from Base List 2.Screen #4 After reviewing spent fuel pool layout drawings and consulting with plant personnel, it was determined that there are no spent fuel pool penetrations below (approximately) ten feet above the top of the fuel assemblies. Therefore, no rapid drain-down items were added to SWEL 2.18 NTTF Recommendation 2.3: Seismic Response Report Sequoyah Unit 1 4.3. SWEL Finalization Once equipment was selected from Base Lists 1 and 2 that qualifies for seismic walkdowns, the equipment was reviewed by the site operations representative and the Peer Review Team. This review resulted in the addition of equipment (Medium Voltage Switchgear) that had not previously been considered to fulfill the Screen #4 for SWEL 1 required equipment types.SWELs 1 and 2 can be found in Appendix D. It should be noted that a total of 121 equipment items were initially selected. It was later clarified that one of the selected items -listed as #17 in SWEL 1 -is not a Seismic Category I Structure, System, or Component. This item was therefore removed from the SWEL, as noted in Appendix D.19 fNTTF Recommendation 2.3: Seismic Response Report Sequoyah Unit 1 5. Seismic Walkdowns and Area Walk-Bys Guidance for performing the walkdowns and walk-bys required for Fukushima NTTF Recommendation 2.3 can be found in the Seismic Walkdown Guidance.The walkdowns and walk-bys were conducted in accordance with this guideline and each was given a final status. If no potentially adverse seismic conditions were noted during a walkdown or walk-by, a YES status was given to the selected piece of equipment or area. If a potentially adverse seismic condition was noted, a NO status was given and a Corrective Action Program (CAP) entry was written. If any equipment was inaccessible, or if a portion of an item of equipment was unobservable, an UNKNOWN status was given.It should also be noted that during the course of performing the walkdowns and walk-bys, five (5) Service Requests (SRs) were generated to address general housekeeping issues which did not present potentially adverse seismic conditions (per the criteria established in the Seismic Walkdown Guidance). Notes were taken regarding these minor housekeeping issues based on general observations made during the course of performing walkdowns and walk-bys.5.1. Seismic Walkdown Procedure One hundred and ten (110) out of one hundred twenty (120) Seismic Walkdowns Checklists (SWCs) were completed at Sequoyah Unit 1. These checklists can be found in Appendix E of this document. The primary types of potentially adverse seismic conditions that were addressed during these walkdowns include:* Bent, broken, missing, or loose hardware* Corrosion (beyond mild surface oxidation)

• Visible cracks in surrounding concrete" Impact of soft targets" Collapsing equipment* Inadequate line flexibility Forty-six (46) Area Walk-by Checklists (AWCs) were completed at Sequoyah Unit 1.These checklists can be found in Appendix F of this document.

The primary areas of observation for potentially adverse seismic conditions that were considered during these walk-bys include: " Anchorage of equipment* Cable/conduit raceways and HVAC ducts" Spatial interactions between equipment" Flooding/Spray hazards* Fire hazards 20 NTTF Recommendation 2.3: Seismic Response Report Sequoyah Unit 1 Housekeeping and temporary equipment There are ten (10) seismic walkdowns that resulted in an unknown status due to plant conditions when operating at 100% power. These walkdowns will be performed during a refueling and maintenance outage that runs October through November 2013.Of the one hundred twenty (120) SWEL items, there were eight (8) pneumatic valves (equipment class 7) and ten (10) motor-operated valves (equipment class 8) for which anchorage configuration verification is not applicable. Anchorage configuration verification for fifty-four (54) out of the one hundred two (102) applicable SWEL items was verified by drawings and/or calculations. For cabinets and panels that were selected for walkdown, NRC guidance was followed to determine which could and could not be opened for internal inspection. An excerpt from the guidance document, Reference 7- FAQ Clarification on Cabinets Walkdown 9-18-12 is shown below-"Cabinets on the SWEL with undue safety or operational hazards can be considered inaccessible and opening of the cabinet can be deferred in accordance with the 50.54(f) letter. For those cabinets that are not to be opened, and will not be placed on the inaccessible list for later inspection (e.g., extensive disassembly is required), licensees should document the justification for not opening the cabinet on the walkdown check sheet." All cabinets meeting the above were documented in the individual walkdowns. 5.2.

Licensing Basis Evaluations 6.1. Licensing Basis Calculations When a potentially adverse seismic condition was identified at SQN, the condition was entered into the corrective action program. No licensing basis evaluations were performed by the walkdown team per TVA expectations to communicate any potential operability concerns as soon as they were identified. All licensing basis determinations were performed by SQN engineering on each CAP entry.The CAP Process at TVA is defined in TVA NPG Standard Program and Processes 22.300 -Corrective Action Program (Reference 11). The CAP program at all TVA Nuclear Facilities consists of five key phases: " Initiation

• Screening* Analysis* Implementation
• Monitoring Multiple CAP entries were generated during the seismic walkdown process at Sequoyah Unit 1. There were a total of twelve CAP entries that were considered potentially adverse seismic conditions and elevated to a Problem Evaluation Report (PER) status.These CAP entries are summarized in Table 5 on the following two pages. All PERs related to this effort are now closed. No conditions outside the licensing basis were found during the course of this walkdown process.23 NTTF Recommendation 2.3: Seismic Response Report Sequoyah Unit 1 No. Location Potentially Adverse PER Potential Action Status Status Seismic Condition(s)

Potentially Adverse Seismic Conditions The potentially adverse seismic conditions summarized above are described in more detail below.6.2.1. Potentially Adverse Seismic Condition 1 While walking down ERCW Pump L-B, O-PMP-067-0440-B, it was noted that one of the motor thrust cooling water line supports had a unistrut clamp that had become dislodged from the unistrut channel. The line is on the supply side to the thrust bearing.The missing clamp presented a potentially adverse seismic condition, since the intended vertical and lateral supports were not being provided as designed.6.2.2. Potentially Adverse Seismic Condition 2 There are two PA speakers above 1- FCV-067-0176. The speaker to the right of the valve is attached to the wall with anchor bolts but it also is positively restrained with a safety cable in case the bolts were to fail. The speaker to the left is attached by anchor bolts but does not have a secondary safety cable attached to the wall. If the speaker was to detach from the wall during a seismic event, it is possible that the speaker could pose a potentially adverse condition with the safety related valves/instruments located directly below the speaker.6.2.3. Potentially Adverse Seismic Condition 3 While performing the area walk by for the 1 B generator bay in the Diesel Generator Building a potentially adverse seismic condition was observed regarding the starting air tank anchorage (1 -TNK-082-0194). It was noted that several of the anchor bolts were not fully seated on the spring/lock washers that were provided. One of the anchor bolts appeared to not have any contact with the installed washer.6.2.4. Potentially Adverse Seismic Condition 4 During the area walk-bys for the areas outside of the 1) Residual Heat Removal (RHR)Pump Rooms and 2) Safety Injection Pump Rooms, it was noted that a 55-gallon drum was not properly restrained. In both cases, the drum is located adjacent to an instrument rack that supports safety related equipment. Per TVA Procedure, the geometry of these drums coupled with the clearance from the temporary equipment requires that the drums have a seismic restraint. 6.2.5. Potentially Adverse Seismic Condition 5 While performing the area walk-by for 480V Board Room 1 B at elevation 749' in the Auxiliary Building, it was noted that a section of the restraint angle at the interface of the block wall and the ceiling was removed for conduit installation. It was also noted that a bolt was missing. It appears as if the missing bolt was previously installed and later removed, since the insert portion of a drop-in anchor is still in place.26 ENTTF Recommendation 2.3: Seismic Response Report Sequoyah Unit 1 6.2.6. Potentially Adverse Seismic Condition 6 A temporary cooling fan was noted to be improperly restrained in the 480V Board Room 1 A. This fan was secured with a chain to an appropriate structure, but the restraint was in a location that would allow the fan to move and tip in a manner that could cause it to strike the nearby 480V shutdown boards. Since many of the relays contained in this cabinet are sensitive, this condition was considered to be potentially seismically adverse.6.2.7. Potentially Adverse Seismic Condition 7 While walking down the Electrical Board Room Chillers and AHU's at elevation 669' in the Control building a bolt and nut were noted as not fully engaged on a System 26 Fire Protection pipe hanger. The hanger is located 12 feet above the floor elevation, on the east side between the A and B Electrical Board Room AHUs (just above the cross connection between the AHUs, closer to the A AHU).6.2.8. Potentially Adverse Seismic Condition 8 During the walkdown of the Shutdown Board B Area, it was noted that Panel 1 A, Reactor Coolant Pump #1 has lighting directly above the panel. The lighting is equipped with a safety wire to prevent the light from impacting the relay panel in case the anchorage fails during a seismic event. It was noted that the safety wire was too long and it would allow for the light fixture to strike the RCP relay panel. Since the relay panel is safety related sensitive equipment, this was deemed a potentially adverse seismic condition. 6.2.9. Potentially Adverse Seismic Condition 9 During the area walk-by for Diesel Generator Bay 1A, it was noted that a nut on one side of a conduit trapeze hanger was not fully engaged. From the floor, the nut appeared to be less than 50% engaged. The trapeze hanger provides support for the conduit running from the 1 A diesel generator pressure switches (0-PS-082-01 64 and 0-PS-082-0174) to the generator engine. This could pose a potentially adverse seismic condition for the conduit and the generator engine assembly.6.2.10. Potentially Adverse Seismic Condition 10 While performing the area walk-by for 6.9kV Shutdown Board B, it was noted that two out of service Personnel Contamination Monitors (PCMs) posed a potential spatial interaction with the fire protection equipment in the area. The PCMs, which are located near a fire hose connection, are neither restrained nor anchored.6.2.11. Potentially Adverse Seismic Condition 11 While performing the area walk-by for the CRDM Room at elevation 759' in the Auxiliary Building, it was noted that a rolling jib crane/monorail was in close proximity to the MG set switchgear. The wheels on the rolling jib crane are locked and a chain is present to provide a horizontal restraint. The chain has been secured on one end to a fixed point but the other end of the chain is not secure as it rests on a pipe support member.27 NTTF Recommendation 2.3: Seismic Response Report Sequoyah Unit 1 6.2.12. Potentially Adverse Seismic Condition 12 During the area walk-by for the Unit 1 669' Penetration Room, it was noted that one straight ladder near instrument racks 1 -L-26-A through 1 -L-26-D (four adjacent racks which are bolted together) had only one restraint. It appeared that there was potential for the ladder to slide off of ductwork (laterally) and impact the instruments on the racks in a seismic event.28 NTTF Recommendation 2.3: Seismic Response Report Sequoyah Unit 1 7. IPEEE Vulnerabilities Resolution Report Information for the IPEEE Vulnerabilities Resolution Report is derived from Reference 5-Seismic Capability Walkdown for IPEEE and Reference 6 -Sequoyah Nuclear Plant (SQN) -Units 1 and 2 -Response to Request for Additional Information on the Individual Plant Examination of External Events.7.1. IPEEE Description In Generic Letter 88-20, Supplement 4, the US NRC requested that the utilities for all active nuclear power plants in the United States perform an evaluation of their nuclear power generating facilities to identify any vulnerabilities associated with the occurrence of several plant-specific external events, and to access the impact of these vulnerabilities on the potential for plant core damage or radioactive material release.This program, designated the Individual Plant Examination of External Events (IPEEE), is a corollary program to the Individual Plant Examination (IPE) which focused on the vulnerabilities associated with the occurrence of external events.After NRC review of the Sequoyah IPEEE Report, it was found that the review level earthquake (RLE) was characterized in a manner that was inconsistent with NUREG-1407, the governing document for IPEEE seismic events. The intent of NUREG-1407 is that the RLE control motion for SQN (which is predominantly a rock site) should be specified at rock outcrop as the NUREG/CR-0098 median 5% damped spectral shape for rock, anchored to a PGA of 0.30g at rock outcrop. The SQN IPEEE appropriately specified the RLE spectral shape as the NUREG/CR-0098 median rock spectrum at rock outcrop, but inappropriately specified the RLE PGA of 0.30g as occurring at the free-field soil surface.7.2. IPEEE Findings and Vulnerabilities The IPEEE Report for the Sequoyah Nuclear Plant addressed multiple vulnerabilities that were identified during the original IPEEE walkdown process. A full list of these vulnerabilities can be found in Reference 5 -Seismic Capability Walkdown for IPEEE.A sample of this list was selected for Recommendation 2.3 walkdowns, and this equipment was added to the SWEL for Sequoyah Unit 1. These selected items of equipment, the issues noted, and the resolutions can be found in Table 6.29 NTTF Recommendation 2.3: Seismic Response Report Sequoyah Unit 1 UNID Description Resolution Date SQN-1 -BDC-201 -FK Inadequate Anchorage / DCN M9859A 7/20/1993 Interaction SQN-1 -BDC-201 -FM Inadequate Anchorage DCN M9859A 7/20/1993 SQN-1 -CLR-030-0201 Corroded anchor bolts: SQ930742PER 10/9/2004* 1 of 6 missing SQN-1 -CMP-313-0458 Missing anchor bolts on SQ930742PER 10/9/2004* compressor SQN-1 -HEX-074-0015 Support frame tabs to DCN M1 1308A 10/4/1994 anchor plates for HX SQN-1 -HEX-074-0027 Support frame tabs to DCN M1 1308A 10/4/1994 anchor plates for HX I I Issue Date of TVA Calculation SCG-8M-0012 Table 6: IPEEE Issues and Resolutions 7.3. NRC IPEEE Review Subsequent to these original SQN high confidence low probability of failure (HCLPF)capacity bounding evaluations and during the NRC Request for Additional Information (RAI) process related to the definition of RLE control motion, the SQN IPEEE RLE was redefined from the free-field soil surface to rock outcrop. As a result, all of the HCLPF capacities as determined by the conservative bounding evaluations were scaled down by a factor of 0.75. Due to this scaling, the HCLPF capacity for many items dropped to below 0.30g (for RLE defined at rock outcrop). However, at that time no additional effort was expended to review in more detail and improve (increase) these HCLPF capacities, especially by eliminating some of the simplifying conservative approximations as used in the original bounding evaluations. A full list of these items can be found in Reference 6 -Sequoyah Nuclear Plant (SQN) -Units 1 and 2- Response to Request for Additional Information on the Individual Plant Examination of External Events. A sample of this list was selected for Recommendation 2.3 walkdowns, and this equipment was added to the SWEL 1 for Sequoyah Unit 1.7.4. Response to IPEEE Review The table on the following page shows the items that were identified as IPEEE outliers after the NRC RAI. Subsequent to the NRC Safety Evaluation Report (SER), action was taken to address identified outliers. For outliers which could not be reconciled through more in-depth seismic analysis, physical modifications and / or replacements were performed, as outlined in the table.30 NTTF Recommendation 2.3: Seismic Response Report Sequoyah Unit 1 I I Item Equipment Description* Re-calculated HCLPF 1 RHR Heat Exchangers (modified 6/18/1995) 2 Main Control Room AHUs 3 Ice Condenser 4 125V Vital Battery Chargers 480 V Shutdown Transformers (minor 5 modification -anchorage replaced 10/25/2012) 6 480 V Shutdown Boards 7 6.9 kV Shutdown Boards Resolved by TVA Calculation 8 Regenerative Heat Exchangers CDQ-000-999-2012-000034 480 V Diesel Aux Boards Dated 10/18/12 480 V Reactor MOV Boards 480V Control & Aux Bldg.

(optional but recommended) Instructions for Completing Checklist This checklist may be used to document the results of the Seismic Walkdown of an item of equipment on the SWEL. The space below each of the following questions may be used to record the results of judgments and findings. Additional space is provided at the end of this checklist for documenting other comments.Note: Y = Yes, N = No, U = Unknown, N/A = Not Applicable Anchorage 1. Is the anchorage configuration verification required (i.e., is the item one of the 50% of SWEL items requiring such verification)?

2. Is the anchorage free of bent, broken, missing or loose hardware?Front kick-plates were removed and anchorage to structure was verified.

Front panels could not be opened due to the presence of sensitive equipment that is utilized in all modes of operation. Back panels would require extensive disassembly to open. Cabinets are filly welded to floor embedded plate.3. Is the anchorage free of corrosion that is more than mild surface oxidation? No corrosion or degraded condition was observed.4.

1. Does anchorage of equipment in the area appear to be free of potentially adverse seismic conditions (if visible without necessarily opening cabinets)?" Anchors on JBI Tank A & B were noted to have bolts that were not tightened down on washers." One anchor on 1B2 Tank A has a slight gap on the front side of the bolt, but it appears to be seated properly on the back (tank)side of the bolt (and is therefore not considered to be an adverse condition).

2. Does anchorage, of equipment in the area appear to be free of significant degraded conditions?

For one duct HVA C support on the back wall behind Engine 1, there is a gap between the baseplate and the wall, as well as concrete spalling which may reduce effective pull-out cone (2 locations). Although this slightly degraded condition is credible, it is insignificant.

Does anchorage of equipment in the area appear to be free of potentially adverse seismic conditions (if visible without necessarily opening cabinets)? Anchors for I-CND-313-0453 have double nut attachments. Four of the anchor bolts have less than 50% engagement for the top nut.

• Risk Management NTTF 2.3/SQN-01 November 2, 2012 PEER REVIEW REPORT Sequoyah Nuclear Plant Unit I Near-Term Task Force 2.3 Seismic Walkdowns A peer review of the Tennessee Valley Authority (TVA) Sequoyah Nuclear Plant -Unit 1 (SQN1)seismic walkdowns for Near-Term Task Force (NTTF) Recommendation 2.3: Seismic was performed in accordance with the U.S. Nuclear Regulatory Commission (NRC) 50.54 (f) letter (listed as Reference 2 in the SQN1 Seismic Response Report) and the guidance provided in Electric Power Research Institute (EPRI) Report 1025286 (listed as Reference 3 in the Seismic Response Report).A highly interactive process was utilized by the peer review team. This involved ongoing open dialog consultation with project participants throughout training, equipment selection, equipment walkdowns, area walkbys, review of potentially adverse seismic conditions and corrective action program documentation, and final report preparation.

In summary, the peer review team is in full concurrence with the final results as documented in the SQN1 Seismic Response Report, and we conclude that all of the project requirements have been met and adequately documented. The following sections summarize the details of the peer review process for the major elements of the project.TRAINING The walkdown teams are described in Section 3 of the SQN1 Seismic Response Report. All of the walkdown team members successfully completed the EPRI developed training on NTTF Recommendation 2.3 -Seismic Walkdown Guidance. All of the individual team members meet the qualification requirements as defined in EPRI Report 1025286. In addition to this EPRI training, per our recommendations, all walkdown team members received additional training.The purpose of the additional training was two-fold. First, additional technical training was provided on equipment anchorage and seismic interaction evaluations, as an enhancement to the anchorage and interaction issues overview provided in the EPRI training course. Second, background information was provided on the site-specific seismic programs implemented by VA at SQN. This provided team members with historical background on the scope and findings of prior seismic reviews, as well as to deepen their understanding of the seismic licensing basis for SQN.Examples of the additional plant-specific training material provided for the team members include the following: " Description of SQN seismic design basis 0.18g Housner-shaped ground motion response spectrum* Scope of the Nuclear Performance Plan (NPP, NUREG 1232, Volume 2) commitments at SQN.

The SWEL 1 includes, as appropriate, various types of systems, classes of equipment, and equipment environments. The SWEL 1 includes new and replacement equipment. The SQN IPEEE review was performed using the EPRI margins methodology and that success path based SSEL associated with SQN1 was used as a starting point for SWEL 1. No seismic PRA has been performed for SQN1 so no information regarding dominant contributors to FACILITY RISK CONSULTANTS, INC.G3 NTTF 2.3/SQN-01 November 2, 2012 Page 3 of 8 seismic risk was available. SWEL 1 was compared to the Core Damage Frequency (CDF) and Large Early Release Frequency (LERF) Rankings, and any shared equipment was noted.The SWEL 2 represents selected equipment related to the spent fuel pool system, including those that could cause rapid drain-down of the pool and accidental exposures of the fuel assemblies. There was considerable interaction between the peer review team, the walkdown team, and the equipment selection team during the course of the evaluation. The final SWEL, as documented in Section 4 and in Appendix D of the SQN1 Seismic Response Report, is a culmination of this interaction. Examples of peer review comments that were adequately addressed and resolved during the SWEL development process include the following: " During the development of the preliminary SWEL, there was confusion regarding the equipment class definition, in particular, instrument racks (18), temperature sensors (19), distribution panels (14) and medium voltage switchgears (03). These were clarified and corrected in the final SWEL. As such, the 120VAC vital instrument power boards are in the distribution panel equipment class, and the 6.9kV shutdown boards are added to the medium voltage switchgear equipment class.* In order to include representative equipment items for all of the 21 classes of equipment listed in Table B-1 of the EPRI Report 1025286, items of equipment were added to the SWEL that were not part of the IPEEE review. It was noted that this was unnecessary yet conservative, so the items remained on the SWEL.* Selected SQN1 equipment items identified as outliers in SQN seismic IPEEE review were added to the SWEL for confirmation of seismic IPEEE upgrades. This is to address reporting of the evaluations related to seismic vulnerabilities identified during that program.* It is noted that the final SWEL adequately includes equipment in each major building structure and encompasses mild to more severe environments. SEISMIC EQUIPMENT WALKDOWNS AND AREA WALKBYS The peer review team spent considerable time interfacing with the walkdown team members during the SQN1 seismic equipment walkdowns and area walkbys. This included responding to questions regarding the scope and content of the reviews. This also included in-plant observations of the teams during the reviews as well as independent in-plant reviews of individual equipment components. Walkdown observations and results were reviewed and discussed on a weekly basis with the walkdown team members. Particular emphasis was given to any items preliminarily identified as potential adverse seismic conditions (see discussion in the next section). In the end, the peer review addressed over 50% of the completed walkdown documentation forms.It is noted that the in-plant activity and over 50% documentation review is above and beyond the peer review requirements as defined in EPRI Report 1025286. As a result of this effort, we are highly confident that the teams conducted the reviews in a thorough and competent manner, and that the reviews are fully in compliance with the intent of the NRC 50.54 (f) letter.Examples of walkdown team observations and seismic issues discussed and resolved during the course of the peer review process for the SQN1 equipment seismic walkdowns and area walkbys include the following: FACILITY RISK CONSULTANTS, INC.G4 NTTF 2.3/SQN-01 November 2, 2012 Page 4 of 8* The walkdown teams diligently verified presence of safety cables or wires on miscellaneous overhead features (such as lights and speakers) and spring locks on florescent light tubes for all electrical equipment panels. Any exceptions were carefully reviewed and discussed.

• The walkdown teams diligently noted all cracks including minor hairline cracks in floors in the vicinity of equipment and even in structural walls. Each instance was discussed at length and resolved, and no items were found to be significant.

For the masonry walls, all of cases were verified to be Seismic Category I reinforced block wall structures, and that hairline cracks were insignificant." The walkdown teams diligently noted all instances of rust on equipment anchors or in the anchorage load path. Each instance was reviewed and discussed. For example, it was determined that the surface rust on the anchors for Spent Fuel Pit Pump 1 B did not affect seismic capacity so was not significant. As another example, minor white colored deposits on the anchors for the Diesel Generator 1A-A Battery Rack were determined to not affect its seismic capacity and accepted as-is." At ERCW Pump L-B, the walkdown teams observed that a Unistrut pipe clamp was slipped out of position and one spring nut was no longer secured. After discussions with team members, they collected the as-built field data and performed a conservative evaluation to verify that the resulting pipe span configuration was adequate even if the questionable pipe clamp were neglected. The configuration was accepted as-is on this basis.* The walkdown teams diligently noted instances of not full thread engagement at bolted connections. Considerable time was spent with the team to assess the capacity of bolted connection with less than full thread engagement. As an example, the rear anchor bolts on ERCW Screen Wash Pump B-B were noted to have about 75% thread engagement. This was accepted as-is on the basis that 75% thread engagement would enable design capacity to be achieved in the anchor, with considerable margin.* The walkdown teams diligently noted instances of bent rod hangers on overhead systems. Based on further discussion, in all cases it was determined that the vertical load carrying capability of the rod hanger was not compromised, and that the rod was likely bent during original construction to provide adequate clearance to adjacent items.Examples include a duct hanger in the vicinity of Diesel Generator (DG) Room IA-A Exhaust Fan 2, a conduit hanger in the Auxiliary Feedwater Pump B area, and a fire protection pipe hanger in the Shutdown Board B Area." At the DG 1A-A Battery Rack, the walkdown teams noted an emergency eye wash station was not anchored to the wall. The eye wash could potentially roll and topple over during a seismic event and spill or spray water in the room. This was determined to not represent a significant hazard to the batteries, and the shift manager was notified of the situation and eye wash was tied off.* The skids for each of the diesel generators were inspected in detail by the walkdown teams, and they had preliminary concerns that the base frames for the engine and the generator were not linked together by steel members as shown on the original design drawings. After considerable discussion and reviewing the load paths, it was concluded that the base frames are very rigid, and that these are each anchored to the same rigid FACILITY RISK CONSULTANTS, INC.G5 NTTF 2.3/SQN-01 November 2, 2012 Page 5 of 8 massive concrete base, so that it was not possible for the engine and the generator to experience any differential seismic movement.* On two instrument racks in the Auxiliary Building, the walkdown team noted that 1 of 4 anchor bolts was missing. However, they also noted that in both cases that the racks were bolted top and bottom to adjacent instrument racks which had all anchors present, so the current configuration would readily meet seismic licensing basis requirements. No further action was required." On electrical panel line-up inspections, the walkdown teams checked for bolting between adjacent panels. In one case, for the DG 1A-A Control Panel, they observed that 1 of 8 bolts was missing in the cabinet-to-cabinet connection. It was agreed that the one missing bolt was insignificant.

• During the area walkbys, the teams noted cases where conduit exiting MCCs were in proximity to overhead rigidly supported cable trays. Examples areas include the DG 1A and 1B Board Rooms. Simple conservative equations were used to estimate deflection, and in all cases it was confirmed that the clearance was adequate for the component design basis earthquake deflections." During the area walkby in 480V Shutdown Board Room 1A2, the walkdown team noted gaps between the ears on a Unistrut clamp and the channel member it was connected to on a fire protection pipe. They were directed to TVA General Specification G-43, which shows this as a typical configuration due to the nature of the clamp type. No further review was required.In the end, the peer review team is in concurrence with the Seismic Walkdown Checklists (SWCs) and Area Walkby Checklists (AWCs) as presented in Appendices E and F, respectively, of the SQN1 Seismic Response Report.POTENTIAL ADVERSE SEISMIC CONDITIONS The peer review team spent considerable time with the walkdown teams addressing preliminary potential adverse seismic conditions identified during walkdowns.

It is noted that there were very many questions early in the walkdown review process on the conservative side of issues, and these kinds of questions diminished towards the end of the project as the judgment of the teams significantly improved. Most of these early concerns were in regards to potential seismic interaction effects. In most cases, these issues were resolved by review of prior evaluations or the TVA procedures and guidance already in place at the plant.All potential adverse seismic conditions were reviewed in detail, including working with the teams to address seismic licensing basis and operability issues, if necessary, for the confirmed potential adverse seismic conditions that resulted in the initiation of Problem Evaluation Reports (PERs) as part of the Corrective Action Program (CAP). In the end, the peer review team is in full concurrence with all of the potential adverse seismic conditions summarized in Section 6.2 of the SQN1 Seismic Response Report.Comments regarding the individual potential adverse seismic conditions for SQN1 include the following:

• Potentially Adverse Seismic Condition 1 addresses a dislodged Unistrut clamp on a motor thrust cooling water line support for ERCW Pump L-B. The walkdown team considered that the missing clamp represented an unanalyzed condition due to lack of FACILITY RISK CONSULTANTS, INC.G6 NTTF 2.3/SQN-01 November 2, 2012 Page 6 of 8 full vertical and lateral support. The resulting configuration with the clamp neglected was shown to be adequate.

The walkdown team conservatively noted this as a potential adverse seismic condition and entered it into the CAP.Potentially Adverse Seismic Condition 2 addresses the lack of a secondary safety cable on a PA speaker above 1-FCV-067-0176. The speaker is light weight, and is attached by anchor bolts to the concrete wall, which would preclude it from falling during a design basis earthquake. However, per SQN typical design details, PA speakers should be safety-wired. The walkdown team conservatively noted this as a potential adverse seismic condition and entered it into the CAP.* Potentially Adverse Seismic Condition 3 addresses base anchor bolts on the diesel generator starting air receiver tank 1-TNK-082-0194 that are not fully seated on their spring/lock washers. It appears that the installation torque did not fully flatten the spring/lock washers. The resulting configuration has full capacity for both tension and shear loading so meets seismic licensing basis requirements, by inspection. The walkdown team conservatively noted this as a potential adverse seismic condition and entered it into the CAP.* Potentially Adverse Seismic Condition 4 addresses unrestrained 55-gallon drums in the vicinity of safety-related instrument rack in the areas outside of the Residual Heat Removal Pump and Safety Injection Pump rooms. In both cases, toppling or sliding of the drums would not compromise the safety function of instrument racks. The unrestrained drums however do not comply with applicable TVA procedures for restraint of temporary items. The walkdown team noted these cases as a potential adverse seismic condition. A CAP entry was submitted to address this issue, and the temporary equipment (drums) were removed from the areas.* Potentially Adverse Seismic Condition 5 addresses a missing bolt and a removed section of angle restraint at the top of a block wall in the 480V Board Room 1 B.Approximate bounding evaluations indicated sufficient margin in the current configuration. The walkdown team conservatively noted this as a potential adverse seismic condition and entered it into the CAP. Subsequently, the design calculation for the current configuration was retrieved, which demonstrates compliance with the design criteria.* Potentially Adverse Seismic Condition 6 addresses a temporary cooling fan in the 480V Board Room 1A that was restrained with a chain; however the chain was not fully effective due to its position on the fan. The current position of the fan did not result in a potential direct hit to the nearby cabinets. The walkdown team noted this as a potential adverse seismic condition. A CAP entry was submitted to address this issue, and the temporary equipment was removed." Potentially Adverse Seismic Condition 7 addresses a nut and bolt not fully engaged on a fire protection pipe hanger in the vicinity of the Electrical Board Room Chillers. The walkdown team was concerned that the nut could loosen and become free during a seismic event. This is not considered to be a credible failure mode, and further evaluations indicated that the pipe hanger was able to perform its intended function.The walkdown team conservatively noted this as a potential adverse seismic condition and entered it into the CAP.FACILITY RISK CONSULTANTS, INC.G7 NTTF 2.3/SQN-01 November 2, 2012 Page 7 of 8" Potentially Adverse Seismic Condition 8 addresses a safety wire on a light fixture near the Reactor Coolant Pump Panel 1A in the Shutdown Board B Area that was observed to be too long to preclude the lighting from striking the panel if it should fall. The light fixture was not directly above the panel, and it was properly anchored to the overhead lighting conduit system. The walkdown team conservatively noted this as a potential adverse seismic condition and entered it into the CAP.* Potentially Adverse Seismic Condition 9 addresses a nut on rod hanger connection for a conduit trapeze hanger in Diesel Generator Bay IA. The estimated 50% thread engagement is sufficient for imposed loading; however the walkdown team was concerned that it could loosen and become disengaged during a seismic event. This is not considered to be a credible failure mode. The walkdown team conservatively noted this as a potential adverse seismic condition and entered it into the CAP." Potentially Adverse Seismic Condition 10 addresses two unrestrained out of service Personnel Contamination Monitors near a fire hose connection in the vicinity of the 6.9kV Shutdown Board B. The walkdown team was concerned that if these were to topple or slide, they could render the fire protection hose as inoperable or block access to the hose station. It is noted that the fire protection system is not safety related. The walkdown team conservatively noted this as a potential adverse seismic condition and entered it into the CAP.* Potentially Adverse Seismic Condition 11 addresses a rolling jib crane/monorail was in close proximity to the MG set switchgear in the CRDM Room. The wheels on the rolling jib crane are locked and a chain is present to provide a horizontal restraint, however one end of the chain was not properly secured. The free end was resting on a pipe support, but did not represent a direct threat to nearby safety-related equipment. The walkdown team conservatively noted this as a potential adverse seismic condition and entered it into the CAP." Potentially Adverse Seismic Condition 12 addresses a partially restrained straight ladder in the vicinity of instrument racks 1-L-26-AID in Auxiliary Building Penetration Room, El.669'. The ladder was restrained only on one side and the walkdown team was concerned that the ladder may potentially slide off of ductwork and impact instruments on the rack. The configuration and geometry of the ladder, duct, and rack preclude credible contact of the ladder and the instruments. The walkdown team conservatively noted this as a potential adverse seismic condition. A CAP entry was submitted to address this issue, and the temporary ladder was removed.SUBMITTAL REPORT The peer review team has reviewed the SQN1 submittal report in detail and we are in full concurrence with the documented observations and findings. The report is in compliance with the guidance in EPRI Report 1025286, and meets the requirements and objectives of the NRC 50.54 (f) letter.In our opinion, the potential adverse seismic conditions identified by the program are in general only minor issues, and this is a reflection of the adequate seismic design criteria as well as sufficiently rigorous seismic-related construction and maintenance procedures that TVA has in place at SQN1. The walkdown demonstrates that the current plant configuration is in FACILITY RISK CONSULTANTS, INC.G8 NTTF 2.3/SQN-01 November 2, 2012 Page 8 of 8 compliance with the current seismic licensing basis. Furthermore, the walkdown demonstrates that that TVA has maintained or improved the seismic IPEEE HCLPF capacity of the plant.Sincerely, John 0. Dizon, P.E.Lead Peer Reviewer Stephen J.
