Executive SummaryAs a result of the Fukushima Daiichi Nuclear Power Plant accident, the U.S. NuclearRegulatory Commission (NRC) required all US nuclear power plants to perform seismicwalkdowns 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 aseries of recommendations.

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

2) that requests information to assure that these recommendations areaddressed by all U.S. nuclear power plants. This report provides guidance forconducting 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 PowerResearch Institute (EPRI) issued a report entitled Seismic Walkdown Guidance forResolution of Fukushima Near-Term Task Force Recommendation 2.3: Seismic(Reference 3 -hereafter "EPRI Seismic Walkdown Guidance") to provide instruction foruniform seismic walkdowns of all U.S. nuclear power plants. This document alsoincludes guidance for reporting the findings of the required walkdowns. At Unit 1 of the Sequoyah Nuclear Power Plant, a total of 120 general Seismic CategoryI equipment items were selected from the original Individual Plant Examination forExternal Events (IPEEE) Safe Shutdown Equipment List (SSEL) to fulfill therequirements of the NTTF-2.3 Seismic Walkdowns. The selected items were located invarious environments and included many different types of equipment from multiplesafety 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 twoseismic engineers and operations personnel, between July 13, 2012 and August 10,2012.Of the 120 equipment items in the Seismic Walkdown Equipment List (SWEL), 110were completed during the walkdown phase. Twelve potentially adverse seismicconditions were found and addressed through the TVA Corrective Action Program.There are ten remaining items of equipment that were inaccessible at 100% power dueto physical limitations or excessive safety hazards. These equipment walkdowns will beperformed during the next Sequoyah Unit 1 refueling outage, scheduled for Octoberthrough November 2013.4 NTTF Recommendation 2.3: Seismic Response ReportSequoyah Unit 12. Seismic Licensing BasisThe seismic licensing basis for the Sequoyah Nuclear Power Plant is derived fromReference 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 ofHamilton County, Tennessee, on a peninsula on the western shore of Chickamauga Lake at Tennessee River mile (TRM) 484.5. The Sequoyah site is approximately 7.5miles northeast of the nearest city limit of Chattanooga, Tennessee, 14 miles west-northwest of Cleveland, Tennessee, and approximately 31 miles south-southwest ofTVA's Watts Bar Nuclear Power Plant. The plant has been designed, built, and isoperated by TVA and contains two identical units. Each of the two units employs aPressurized Water Reactor Nuclear Steam Supply System with four coolant loops,furnished by Westinghouse Electric Corporation. Unit 1 began commercial operation inJuly 1, 1981.2.2. Ground Response SpectraThe seismic design basis for Sequoyah Nuclear Power Plant is the 0.18g horizontal peak ground acceleration represented by the modified Housner-shape spectrum forSafe Shutdown Earthquake (SSE). Operating Basis Earthquake (OBE) is one-half ofSSE ground acceleration. Vertical ground acceleration is two-thirds of the horizontal ground acceleration. Figure 1 illustrates the relationship between the 5% damped minimum design responsespectra and the actual site seismic design response spectra for the SSE used in thedesign of rock-supported structures. 5 NTTF Recommendation 2.3: Seismic Response ReportSequoyah Unit 1W'10%410eý-W --I 'kZ14 14"Nvzzrf'j-V ACr' VN'-XC1 vi*,V-kZel Im --,402000.0.060.04.'01.04fF~ 4x A \1XA)1~?VAY LN A N7!X(\ i~tWX:1 A A' ~.

Equipment and SystemsNuclear Steam Supply System (NSSS) components and equipment supplied byWestinghouse have been qualified in accordance with the applicable seismicqualification requirements. Seismic qualification requirements for Seismic Category Isystems and components are consistent with Institute of Electrical and Electronics Engineers (IEEE) Standard 344-1971. Seismic Category I mechanical equipment hasbeen 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 anddeformation behavior were maintained within the allowable limits when subjected tonormal operating conditions combined with the seismic effects resulting from theresponse to the OBE. In addition, the stresses that resulted from normal loadscombined 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.

Theallowable limits are defined in appropriate design standards including: o American Society of Mechanical Engineers (ASME) Boiler and Pressure VesselCode, 1986o American National Standards Institute (ANSI) Code for Pressure Piping ANSIB31.1.0, Power Piping, 19670 AISC Specification for the Design, Fabrication and Erection of Structural Steel forBuildings, February 12, 19698 NTTF Recommendation 2.3: Seismic Response ReportSequoyah Unit 13.

To prepare for the seismic walkdowns, Mr. Malone and Mr. Antanaitis completed theNTTF 2.3 Seismic Walkdown Training Course developed by EPRI. This course was9 NTTF Recommendation 2.3: Seismic Response ReportSequoyah Unit 1held at MPR Associates, Inc. in Alexandria, VA. It is noted in Frequently AskedQuestions on Seismic Walkdown

Guidance, Reference 8, that completion of this coursequalifies those in attendance to facilitate presentation of course material in subsequent training sessions for others. Mr. Summers, Mr. York, and Mr. Edgar completed thecourse 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 alsocompleted the EPRI course in Virginia.

In addition to the walkdown training course developed by EPRI, all seismic walkdownengineers 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 issueshistorically experienced at Sequoyah Nuclear Plant. The site-specific training alsoprovided 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 instructural

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 thedevelopment of the equipment sample, the individuals listed above reviewed the IPEEEsubmittal report and the subsequent Request for Additional Information (RAI), identified 10 NTTF Recommendation 2.3: Seismic Response ReportSequoyah Unit 1appropriate

outliers, and extracted the SSEL which became the basis for SWELdevelopment.

The results of this process were reviewed by the Peer Review Teammembers, whose applicable IPEEE-related experience is outlined in Section 3.5 below.3.5. Peer Review TeamThe personnel involved in the peer review process are:* John Dizon, Professional Engineer with over 30 years of experience in the field ofcivil and structural engineering, earthquake engineering, risk assessment andproject management.

• Steve Eder, Professional Engineer with over 30 years of experience in the field ofcivil and structural engineering, project management, seismic engineering, and riskmanagement 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 plantdesign, plant operations, plant documentation, and associated SSCs. Past experience at SQN includes seismic design criteria development, verification of Seismic CategoryI(L) piping, and assistance on seismic qualification of cable trays, conduit, and othermiscellaneous 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 seismicIPEEE, for control motion re-defined at rock outcrop.11 NTTF Recommendation 2.3: Seismic Response ReportSequoyah Unit 14. Selection of Structures, Systems and Components The selection of SSCs for the Recommendation 2.3 Seismic walkdowns followed theguidelines provided in the EPRI Seismic Walkdown Guidance.

The combined SWEL forSequoyah Unit 1, which consists of 120 items of equipment, adequately addresses allrequired 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 EPRISeismic Walkdown Guidance. A schematic of the screening process taken directly fromthe EPRI Seismic Walkdown Guidance is shown below -AbFigure 2: SWEL 1 Selection ProcessScreens #1 through #3The.development of SWEL 1 began with the SSEL that was developed as part of theIPEEE implementation at Sequoyah, found in Reference 5 -Seismic Capability 12 NTTF Recommendation 2.3: Seismic Response ReportSequoyah Unit 1Walkdown for IPEEE. This list fulfills the requirements of Screens #1 through #3 shownabove.It should be noted that an additional safety function "0 -Support Function" was addedto 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 fivesafety functions. The expanded safety function list is shown below:0. Support function1. Reactor reactivity control2. Reactor coolant pressure control3. Reactor coolant inventory control4. Decay heat removal5. Containment functionThe SSEL with assigned safety functions are presented in Appendix B as Base List 1.Screen #4From Base List 1, equipment meeting three of the five screen requirements (system,equipment type, and environment) was identified. The systems and equipment typeswere chosen based on the criteria provided in the EPRI Seismic Walkdown Guidance. The equipment environments selected for screen #4, which were not explicitly definedby 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 SeismicWalkdown 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 theEPRI 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 withplant operations to identify system enhancements resulting in new or replacedequipment.

SWEL 2 Selection The SWEL 2 selection screening process was performed in accordance with the EPRISeismic Walkdown Guidance. A schematic of the screening process taken directly fromthe EPRI Seismic Walkdown Guidance is shown below:17 NTTF Recommendation 2.3: Seismic Response ReportSequoyah Unit 1Figure 3: SWEL 2 Selection ProcessScreens #1 through #2The Master Equipment List for Sequoyah Nuclear Plant was utilized to retrieve acomplete list of all Seismic Category 1 spent fuel pool systems and equipment. This listis presented in Appendix C as Base List 2.Screen #3The Spent Fuel Pool System at Sequoyah was limited to a single environment and asingle system with no new or replacement equipment since the IPEEE analysis. Therefore the only screen #3 requirement that could be met was that of varyingequipment type. Two items of differing equipment types were selected from Base List 2.Screen #4After reviewing spent fuel pool layout drawings and consulting with plant personnel, itwas determined that there are no spent fuel pool penetrations below (approximately) tenfeet above the top of the fuel assemblies. Therefore, no rapid drain-down items wereadded to SWEL 2.18 NTTF Recommendation 2.3: Seismic Response ReportSequoyah Unit 14.3. SWEL Finalization Once equipment was selected from Base Lists 1 and 2 that qualifies for seismicwalkdowns, the equipment was reviewed by the site operations representative and thePeer Review Team. This review resulted in the addition of equipment (Medium VoltageSwitchgear) that had not previously been considered to fulfill the Screen #4 for SWEL 1required equipment types.SWELs 1 and 2 can be found in Appendix D. It should be noted that a total of 121equipment items were initially selected. It was later clarified that one of the selecteditems -listed as #17 in SWEL 1 -is not a Seismic Category I Structure, System, orComponent. This item was therefore removed from the SWEL, as noted in Appendix D.19 fNTTF Recommendation 2.3: Seismic Response ReportSequoyah Unit 15. Seismic Walkdowns and Area Walk-BysGuidance for performing the walkdowns and walk-bys required for Fukushima NTTFRecommendation 2.3 can be found in the Seismic Walkdown Guidance. The walkdowns and walk-bys were conducted in accordance with this guideline andeach was given a final status. If no potentially adverse seismic conditions were notedduring a walkdown or walk-by, a YES status was given to the selected piece ofequipment or area. If a potentially adverse seismic condition was noted, a NO statuswas 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, anUNKNOWN 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 criteriaestablished in the Seismic Walkdown Guidance). Notes were taken regarding theseminor housekeeping issues based on general observations made during the course ofperforming 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 foundin Appendix E of this document. The primary types of potentially adverse seismicconditions 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 ofobservation for potentially adverse seismic conditions that were considered during thesewalk-bys include:" Anchorage of equipment

• Cable/conduit raceways and HVAC ducts" Spatial interactions between equipment

" Flooding/Spray hazards* Fire hazards20 NTTF Recommendation 2.3: Seismic Response ReportSequoyah Unit 1Housekeeping and temporary equipment There are ten (10) seismic walkdowns that resulted in an unknown status due to plantconditions when operating at 100% power. These walkdowns will be performed duringa 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 whichanchorage configuration verification is not applicable. Anchorage configuration verification for fifty-four (54) out of the one hundred two (102) applicable SWEL itemswas verified by drawings and/or calculations. For cabinets and panels that were selected for walkdown, NRC guidance was followedto determine which could and could not be opened for internal inspection. An excerptfrom 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 beconsidered 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 notbe placed on the inaccessible list for later inspection (e.g., extensive disassembly is required),

licensees should document the justification for not opening the cabineton 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 wasentered into the corrective action program. No licensing basis evaluations wereperformed 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 TVANuclear Facilities consists of five key phases:" Initiation

• Screening
• Analysis* Implementation
• Monitoring Multiple CAP entries were generated during the seismic walkdown process at SequoyahUnit 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 PERsrelated to this effort are now closed. No conditions outside the licensing basis werefound during the course of this walkdown process.23 NTTF Recommendation 2.3: Seismic Response ReportSequoyah Unit 1No. Location Potentially Adverse PER Potential Action Status StatusSeismic Condition(s)

Potentially Adverse Seismic Conditions The potentially adverse seismic conditions summarized above are described in moredetail below.6.2.1. Potentially Adverse Seismic Condition 1While walking down ERCW Pump L-B, O-PMP-067-0440-B, it was noted that one of themotor thrust cooling water line supports had a unistrut clamp that had becomedislodged 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 theintended vertical and lateral supports were not being provided as designed. 6.2.2. Potentially Adverse Seismic Condition 2There are two PA speakers above 1- FCV-067-0176. The speaker to the right of thevalve is attached to the wall with anchor bolts but it also is positively restrained with asafety cable in case the bolts were to fail. The speaker to the left is attached by anchorbolts but does not have a secondary safety cable attached to the wall. If the speakerwas to detach from the wall during a seismic event, it is possible that the speaker couldpose a potentially adverse condition with the safety related valves/instruments locateddirectly below the speaker.6.2.3. Potentially Adverse Seismic Condition 3While 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 airtank anchorage (1 -TNK-082-0194). It was noted that several of the anchor bolts werenot fully seated on the spring/lock washers that were provided. One of the anchor boltsappeared to not have any contact with the installed washer.6.2.4. Potentially Adverse Seismic Condition 4During 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 drumwas not properly restrained. In both cases, the drum is located adjacent to aninstrument rack that supports safety related equipment. Per TVA Procedure, thegeometry 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 5While performing the area walk-by for 480V Board Room 1 B at elevation 749' in theAuxiliary

Building, it was noted that a section of the restraint angle at the interface of theblock wall and the ceiling was removed for conduit installation.

It was also noted that abolt was missing. It appears as if the missing bolt was previously installed and laterremoved, since the insert portion of a drop-in anchor is still in place.26 ENTTF Recommendation 2.3: Seismic Response ReportSequoyah Unit 16.2.6. Potentially Adverse Seismic Condition 6A temporary cooling fan was noted to be improperly restrained in the 480V Board Room1 A. This fan was secured with a chain to an appropriate structure, but the restraint wasin a location that would allow the fan to move and tip in a manner that could cause it tostrike the nearby 480V shutdown boards. Since many of the relays contained in thiscabinet are sensitive, this condition was considered to be potentially seismically adverse.6.2.7. Potentially Adverse Seismic Condition 7While walking down the Electrical Board Room Chillers and AHU's at elevation 669' inthe Control building a bolt and nut were noted as not fully engaged on a System 26 FireProtection pipe hanger. The hanger is located 12 feet above the floor elevation, on theeast side between the A and B Electrical Board Room AHUs (just above the crossconnection between the AHUs, closer to the A AHU).6.2.8. Potentially Adverse Seismic Condition 8During 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 isequipped with a safety wire to prevent the light from impacting the relay panel in casethe anchorage fails during a seismic event. It was noted that the safety wire was toolong and it would allow for the light fixture to strike the RCP relay panel. Since the relaypanel is safety related sensitive equipment, this was deemed a potentially adverseseismic condition. 6.2.9. Potentially Adverse Seismic Condition 9During the area walk-by for Diesel Generator Bay 1A, it was noted that a nut on oneside of a conduit trapeze hanger was not fully engaged. From the floor, the nutappeared to be less than 50% engaged. The trapeze hanger provides support for theconduit 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 seismiccondition for the conduit and the generator engine assembly. 6.2.10. Potentially Adverse Seismic Condition 10While performing the area walk-by for 6.9kV Shutdown Board B, it was noted that twoout of service Personnel Contamination Monitors (PCMs) posed a potential spatialinteraction with the fire protection equipment in the area. The PCMs, which are locatednear a fire hose connection, are neither restrained nor anchored. 6.2.11. Potentially Adverse Seismic Condition 11While 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 MGset switchgear.

The wheels on the rolling jib crane are locked and a chain is present toprovide a horizontal restraint. The chain has been secured on one end to a fixed pointbut the other end of the chain is not secure as it rests on a pipe support member.27 NTTF Recommendation 2.3: Seismic Response ReportSequoyah Unit 16.2.12. Potentially Adverse Seismic Condition 12During the area walk-by for the Unit 1 669' Penetration Room, it was noted that onestraight ladder near instrument racks 1 -L-26-A through 1 -L-26-D (four adjacent rackswhich 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 racksin a seismic event.28 NTTF Recommendation 2.3: Seismic Response ReportSequoyah Unit 17. IPEEE Vulnerabilities Resolution ReportInformation 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 theIndividual Plant Examination of External Events.7.1. IPEEE Description In Generic Letter 88-20, Supplement 4, the US NRC requested that the utilities for allactive nuclear power plants in the United States perform an evaluation of their nuclearpower generating facilities to identify any vulnerabilities associated with the occurrence of several plant-specific external events, and to access the impact of thesevulnerabilities 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 thevulnerabilities associated with the occurrence of external events.After NRC review of the Sequoyah IPEEE Report, it was found that the review levelearthquake (RLE) was characterized in a manner that was inconsistent with NUREG-1407, the governing document for IPEEE seismic events. The intent of NUREG-1407 isthat the RLE control motion for SQN (which is predominantly a rock site) should bespecified at rock outcrop as the NUREG/CR-0098 median 5% damped spectral shapefor 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 atrock outcrop, but inappropriately specified the RLE PGA of 0.30g as occurring at thefree-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 thesevulnerabilities can be found in Reference 5 -Seismic Capability Walkdown for IPEEE.A sample of this list was selected for Recommendation 2.3 walkdowns, and thisequipment was added to the SWEL for Sequoyah Unit 1. These selected items ofequipment, the issues noted, and the resolutions can be found in Table 6.29 NTTF Recommendation 2.3: Seismic Response ReportSequoyah Unit 1UNID Description Resolution DateSQN-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 missingSQN-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 HXSQN-1 -HEX-074-0027 Support frame tabs to DCN M1 1308A 10/4/1994 anchor plates for HX IIIssue Date of TVA Calculation SCG-8M-0012 Table 6: IPEEE Issues and Resolutions 7.3. NRC IPEEE ReviewSubsequent 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 wasredefined from the free-field soil surface to rock outcrop. As a result, all of the HCLPFcapacities as determined by the conservative bounding evaluations were scaled downby a factor of 0.75. Due to this scaling, the HCLPF capacity for many items dropped tobelow 0.30g (for RLE defined at rock outcrop).

However, at that time no additional effortwas expended to review in more detail and improve (increase) these HCLPF capacities, especially by eliminating some of the simplifying conservative approximations as usedin 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 PlantExamination 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 ReviewThe table on the following page shows the items that were identified as IPEEE outliersafter the NRC RAI. Subsequent to the NRC Safety Evaluation Report (SER), actionwas 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 ReportSequoyah Unit 1IIItem Equipment Description* Re-calculated HCLPF1 RHR Heat Exchangers (modified 6/18/1995) 2 Main Control Room AHUs3 Ice Condenser 4 125V Vital Battery Chargers480 V Shutdown Transformers (minor5 modification -anchorage replaced10/25/2012) 6 480 V Shutdown Boards7 6.9 kV Shutdown Boards Resolved by TVA Calculation 8 Regenerative Heat Exchangers CDQ-000-999-2012-000034 480 V Diesel Aux Boards Dated 10/18/12480 V Reactor MOV Boards480V 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 theSWEL. The space below each of the following questions may be used to record the results of judgments andfindings. 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 oneof 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 wasverified. Front panels could not be opened due to the presence ofsensitive equipment that is utilized in all modes of operation. Backpanels would require extensive disassembly to open. Cabinets are fillywelded to floor embedded plate.3. Is the anchorage free of corrosion that is more than mild surfaceoxidation? No corrosion or degraded condition was observed.

4. Is the anchorage free of visible cracks in the concrete near the anchors?5. Is the anchorage configuration consistent with plant documentation?

(Note: This question only applies if the item is one of the 50% forwhich an anchorage configuration verification is required.) Anchorage configuration is consistent with Drawings I 0N320-2,18N243, and calculation SCG-4M-00169.

6. Based on the above anchorage evaluations, is the anchorage free ofpotentially adverse seismic conditions?

1. Does anchorage of equipment in the area appear to be free ofpotentially adverse seismic conditions (if visible without necessarily opening cabinets)?

Instrument racks 1-L-26A -D are adjacent and bolted together. Eachis designed to use four anchor bolts as stand-alone frames. Only two tothree anchor bolts are used for racks A-C, since the frames are boltedtogether. This arrangement is not considered to be seismically adverse,since each joint anchor point has at least one anchor bolt (and theframes are bolted together at the top and bottom).2.

• Risk Management NTTF 2.3/SQN-01 November 2, 2012PEER REVIEW REPORTSequoyah Nuclear Plant Unit INear-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 wasperformed 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 inElectric Power Research Institute (EPRI) Report 1025286 (listed as Reference 3 in the SeismicResponse Report).A highly interactive process was utilized by the peer review team. This involved ongoing opendialog consultation with project participants throughout

training, equipment selection, equipment walkdowns, area walkbys, review of potentially adverse seismic conditions and corrective actionprogram documentation, and final report preparation.

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

control, reactor coolant pressure control,reactor coolant inventory

control, decay heat removal, and containment function.

The SWEL 1includes, 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 successpath based SSEL associated with SQN1 was used as a starting point for SWEL 1. No seismicPRA has been performed for SQN1 so no information regarding dominant contributors toFACILITY RISK CONSULTANTS, INC.G3 NTTF 2.3/SQN-01 November 2, 2012Page 3 of 8seismic risk was available. SWEL 1 was compared to the Core Damage Frequency (CDF) andLarge 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 fuelassemblies. There was considerable interaction between the peer review team, the walkdown team, and theequipment 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 thisinteraction. Examples of peer review comments that were adequately addressed and resolvedduring the SWEL development process include the following: " During the development of the preliminary SWEL, there was confusion regarding theequipment class definition, in particular, instrument racks (18), temperature sensors (19),distribution panels (14) and medium voltage switchgears (03). These were clarified andcorrected in the final SWEL. As such, the 120VAC vital instrument power boards are inthe distribution panel equipment class, and the 6.9kV shutdown boards are added to themedium 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 theSWEL 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 reviewwere added to the SWEL for confirmation of seismic IPEEE upgrades. This is toaddress reporting of the evaluations related to seismic vulnerabilities identified duringthat program.* It is noted that the final SWEL adequately includes equipment in each major buildingstructure and encompasses mild to more severe environments. SEISMIC EQUIPMENT WALKDOWNS AND AREA WALKBYSThe peer review team spent considerable time interfacing with the walkdown team membersduring the SQN1 seismic equipment walkdowns and area walkbys. This included responding toquestions regarding the scope and content of the reviews. This also included in-plantobservations of the teams during the reviews as well as independent in-plant reviews ofindividual equipment components. Walkdown observations and results were reviewed anddiscussed on a weekly basis with the walkdown team members. Particular emphasis was givento any items preliminarily identified as potential adverse seismic conditions (see discussion inthe next section). In the end, the peer review addressed over 50% of the completed walkdowndocumentation forms.It is noted that the in-plant activity and over 50% documentation review is above and beyond thepeer review requirements as defined in EPRI Report 1025286. As a result of this effort, we arehighly 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 duringthe course of the peer review process for the SQN1 equipment seismic walkdowns and areawalkbys include the following: FACILITY RISK CONSULTANTS, INC.G4 NTTF 2.3/SQN-01 November 2, 2012Page 4 of 8* The walkdown teams diligently verified presence of safety cables or wires onmiscellaneous overhead features (such as lights and speakers) and spring locks onflorescent 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 floorsin the vicinity of equipment and even in structural walls. Each instance was discussed atlength 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, andthat hairline cracks were insignificant. " The walkdown teams diligently noted all instances of rust on equipment anchors or in theanchorage load path. Each instance was reviewed and discussed. For example, it wasdetermined that the surface rust on the anchors for Spent Fuel Pit Pump 1 B did notaffect seismic capacity so was not significant. As another example, minor white coloreddeposits on the anchors for the Diesel Generator 1A-A Battery Rack were determined tonot affect its seismic capacity and accepted as-is." At ERCW Pump L-B, the walkdown teams observed that a Unistrut pipe clamp wasslipped out of position and one spring nut was no longer secured. After discussions withteam 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 thequestionable pipe clamp were neglected. The configuration was accepted as-is on thisbasis.* The walkdown teams diligently noted instances of not full thread engagement at boltedconnections. Considerable time was spent with the team to assess the capacity ofbolted connection with less than full thread engagement. As an example, the rearanchor bolts on ERCW Screen Wash Pump B-B were noted to have about 75% threadengagement. This was accepted as-is on the basis that 75% thread engagement wouldenable design capacity to be achieved in the anchor, with considerable margin.* The walkdown teams diligently noted instances of bent rod hangers on overheadsystems. Based on further discussion, in all cases it was determined that the verticalload carrying capability of the rod hanger was not compromised, and that the rod waslikely 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-AExhaust Fan 2, a conduit hanger in the Auxiliary Feedwater Pump B area, and a fireprotection pipe hanger in the Shutdown Board B Area." At the DG 1A-A Battery Rack, the walkdown teams noted an emergency eye washstation was not anchored to the wall. The eye wash could potentially roll and topple overduring a seismic event and spill or spray water in the room. This was determined to notrepresent a significant hazard to the batteries, and the shift manager was notified of thesituation and eye wash was tied off.* The skids for each of the diesel generators were inspected in detail by the walkdownteams, and they had preliminary concerns that the base frames for the engine and thegenerator were not linked together by steel members as shown on the original designdrawings. 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 rigidFACILITY RISK CONSULTANTS, INC.G5 NTTF 2.3/SQN-01 November 2, 2012Page 5 of 8massive concrete base, so that it was not possible for the engine and the generator toexperience any differential seismic movement.

• On two instrument racks in the Auxiliary

Building, the walkdown team noted that 1 of 4anchor bolts was missing.

However, they also noted that in both cases that the rackswere 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 betweenadjacent panels. In one case, for the DG 1A-A Control Panel, they observed that 1 of 8bolts was missing in the cabinet-to-cabinet connection. It was agreed that the onemissing bolt was insignificant.

• During the area walkbys, the teams noted cases where conduit exiting MCCs were inproximity to overhead rigidly supported cable trays. Examples areas include the DG 1Aand 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 notedgaps between the ears on a Unistrut clamp and the channel member it was connected toon a fire protection pipe. They were directed to TVA General Specification G-43, whichshows this as a typical configuration due to the nature of the clamp type. No furtherreview 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 werevery 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 theteams significantly improved. Most of these early concerns were in regards to potential seismicinteraction effects. In most cases, these issues were resolved by review of prior evaluations orthe TVA procedures and guidance already in place at the plant.All potential adverse seismic conditions were reviewed in detail, including working with theteams 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 infull concurrence with all of the potential adverse seismic conditions summarized in Section 6.2of the SQN1 Seismic Response Report.Comments regarding the individual potential adverse seismic conditions for SQN1 include thefollowing:

• Potentially Adverse Seismic Condition 1 addresses a dislodged Unistrut clamp on amotor thrust cooling water line support for ERCW Pump L-B. The walkdown teamconsidered that the missing clamp represented an unanalyzed condition due to lack ofFACILITY RISK CONSULTANTS, INC.G6 NTTF 2.3/SQN-01 November 2, 2012Page 6 of 8full vertical and lateral support.

The resulting configuration with the clamp neglected wasshown 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 cableon a PA speaker above 1-FCV-067-0176. The speaker is light weight, and is attachedby anchor bolts to the concrete wall, which would preclude it from falling during a designbasis earthquake.

However, per SQN typical design details, PA speakers should besafety-wired.

The walkdown team conservatively noted this as a potential adverseseismic condition and entered it into the CAP.* Potentially Adverse Seismic Condition 3 addresses base anchor bolts on the dieselgenerator starting air receiver tank 1-TNK-082-0194 that are not fully seated on theirspring/lock washers. It appears that the installation torque did not fully flatten thespring/lock washers. The resulting configuration has full capacity for both tension andshear loading so meets seismic licensing basis requirements, by inspection. Thewalkdown team conservatively noted this as a potential adverse seismic condition andentered it into the CAP.* Potentially Adverse Seismic Condition 4 addresses unrestrained 55-gallon drums in thevicinity of safety-related instrument rack in the areas outside of the Residual HeatRemoval Pump and Safety Injection Pump rooms. In both cases, toppling or sliding ofthe drums would not compromise the safety function of instrument racks. Theunrestrained drums however do not comply with applicable TVA procedures for restraint of temporary items. The walkdown team noted these cases as a potential adverseseismic 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 removedsection 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 currentconfiguration. The walkdown team conservatively noted this as a potential adverseseismic condition and entered it into the CAP. Subsequently, the design calculation forthe current configuration was retrieved, which demonstrates compliance with the designcriteria.

• Potentially Adverse Seismic Condition 6 addresses a temporary cooling fan in the 480VBoard Room 1A that was restrained with a chain; however the chain was not fullyeffective due to its position on the fan. The current position of the fan did not result in apotential 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 thetemporary equipment was removed." Potentially Adverse Seismic Condition 7 addresses a nut and bolt not fully engaged on afire protection pipe hanger in the vicinity of the Electrical Board Room Chillers. Thewalkdown team was concerned that the nut could loosen and become free during aseismic event. This is not considered to be a credible failure mode, and furtherevaluations 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, 2012Page 7 of 8" Potentially Adverse Seismic Condition 8 addresses a safety wire on a light fixture nearthe Reactor Coolant Pump Panel 1A in the Shutdown Board B Area that was observedto be too long to preclude the lighting from striking the panel if it should fall. The lightfixture was not directly above the panel, and it was properly anchored to the overheadlighting 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 aconduit trapeze hanger in Diesel Generator Bay IA. The estimated 50% threadengagement is sufficient for imposed loading; however the walkdown team wasconcerned that it could loosen and become disengaged during a seismic event. This isnot considered to be a credible failure mode. The walkdown team conservatively notedthis as a potential adverse seismic condition and entered it into the CAP." Potentially Adverse Seismic Condition 10 addresses two unrestrained out of servicePersonnel Contamination Monitors near a fire hose connection in the vicinity of the6.9kV Shutdown Board B. The walkdown team was concerned that if these were totopple or slide, they could render the fire protection hose as inoperable or block accessto the hose station. It is noted that the fire protection system is not safety related. Thewalkdown team conservatively noted this as a potential adverse seismic condition andentered it into the CAP.* Potentially Adverse Seismic Condition 11 addresses a rolling jib crane/monorail was inclose proximity to the MG set switchgear in the CRDM Room. The wheels on the rollingjib crane are locked and a chain is present to provide a horizontal restraint, however oneend 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 walkdownteam conservatively noted this as a potential adverse seismic condition and entered itinto the CAP." Potentially Adverse Seismic Condition 12 addresses a partially restrained straight ladderin 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 wasconcerned 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 precludecredible contact of the ladder and the instruments. The walkdown team conservatively noted this as a potential adverse seismic condition. A CAP entry was submitted toaddress this issue, and the temporary ladder was removed.SUBMITTAL REPORTThe peer review team has reviewed the SQN1 submittal report in detail and we are in fullconcurrence with the documented observations and findings. The report is in compliance withthe guidance in EPRI Report 1025286, and meets the requirements and objectives of the NRC50.54 (f) letter.In our opinion, the potential adverse seismic conditions identified by the program are in generalonly minor issues, and this is a reflection of the adequate seismic design criteria as well assufficiently rigorous seismic-related construction and maintenance procedures that TVA has inplace at SQN1. The walkdown demonstrates that the current plant configuration is inFACILITY RISK CONSULTANTS, INC.G8 NTTF 2.3/SQN-01 November 2, 2012Page 8 of 8compliance 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 ReviewerStephen J.
