Fukushima Near-Term Task Force (NTTF) Recommendation 2.3:NRC Submittal Report for Seismic Walkdowns McGuire Unit 1Page 1 of 15Rev. 1Revision Log:Rev. 0 Initial NRC submittal dated November 26, 2012Rev. 1 Supplemental NRC submittal to address "initially" inaccessible components.

Revised pages 1-15, Added ATTACHMENTS 7 & 8.Executive SummaryThe results of the McGuire Unit 1 Fukushima Dai-ichi Near-Term Task Force (NTTF)Recommendation 2.3 Seismic Walkdowns are provided here-in.

The walkdowns were performed in accordance with Electric Power Research Institute (EPRI) Report 1025286, Seismic WalkdownGuidance for Resolution of Fukushima Near-Term Task Force Recommendation 2.3: Seismic(issued June 2012). The performance of the seismic walkdowns is required in response to theNuclear Regulatory Commission's (NRC) 10CFR50.54(f) letter regarding NTTFRecommendation 2.3: Seismic.

The EPRI guidance outlined requirements for personnel qualifications, selection of walkdown components, the conduct of the walkdowns, evaluation ofpotentially adverse conditions against the plant seismic licensing basis, and reporting requirements.

The guidance further provided check lists to document the performance of theseismic walkdowns and walk-bys.

Revision 0 of the submittal report documented the walkdown results for the accessible components as of November 2012. Revision 1 of the submittal report added the walkdownresults for the previously in-accessible components.

1.0 Seismic Licensing BasisSite Characteristics:

Major Category I structures are supported on sound rock (UFSAR Sections 3.7.1.4, 3.7.1.5,3.7.1.6, 3.8.4, 3.8.5, 3.8.5.4.1).

Where zones of irregular weathering of bedrock occurred, theweathered material was excavated and fill concrete was used under foundation structures, orpiles were driven to suitable rock bearing for Category I structure (UFSAR Section 2.5.1.2).

Response Spectra:The Safe Shutdown Earthquake (SSE) for McGuire is conservatively specified to have a peakground acceleration of 0.15g horizontally and 0.10 g vertically.

The Operating Basis Earthquake (OBE) is 8/15 of the SSE at all frequencies (UFSAR 2.5.2.6, 2.5.2.11, 3.1, and MCS-1465.00 0009, section 3.3).The ground response spectra curves are enveloped for analysis and design of all Category 1building foundations on closely joined rock and slightly weathered rock and for all buildingelevations where the floor slab rests on rock or fill concrete (MCS-1465.00-00-0009, section 3.3).

Fukushima Near-Term Task Force (NTTF) Recommendation 2.3:NRC Submittal Report for Seismic Walkdowns McGuire Unit 1Page 2 of 15Rev. 1System, Structure, Component (SSC) Seismic Design:All structures, systems and components required to shut down and maintain the reactor in a safeand orderly condition or prevent the uncontrolled release of excessive amounts of radioactivity havea seismic classification of Category 1 (UFSAR 3.2.1). The McGuire design complies withRegulatory Guide 1.29 for SSC seismic design requirements.

Seismic Category I SSCs are designed to maintain their functional capability in-the event of aSSE. The seismic design of Category I SSCs is outlined in UFSAR Section 3.2 and Tables 3-1,3-2, 3-4 & 3-7. Seismic Category I SSCs are also designed to withstand the effects of theOperating Basis Earthquake without loss of capability to perform their safety functions.

Applicable seismic design codes and standards include (MCS-1465.00-00-0009, Section 3.2,UFSAR section 3.2 and Tables 3-1 through 3-7):" 10CFR50, Appendix A, General Design Criteria 2 -Design Bases for Protection AgainstNatural Phenomena

Fukushima Near-Term Task Force (NTTF) Recommendation 2.3:NRC Submittal Report for Seismic Walkdowns McGuire Unit 1Page 4 of 15Rev. 13.0 Selection of Equipment for the SWEL-1 and SWEL-2 ListsThe McGuire Unit 1 SWEL-1 and SWEL-2 equipment selection was performed in accordance with the EPRI guidance outlined in EPRI Technical Report #1025286 (Reference MCC-1612.00-00-0001, Rev. 0).The EPRI SWEL-1 Screening Criteria

1. 1 through #3 are as follows:1) Seismic Category I licensing bases,2) Exclude structures, penetrations, and piping systems3) Equipment must perform safety function (reactor reactivity

control, reactor coolantpressure

control, reactor coolant inventory

control, decay heat removal, containment integrity).

The EPRI screening criteria further allows major NSSS equipment insidecontainment to be excluded.

The original McGuire IPEEE Seismic Walkdown list (MCC-1535.00-00-0004, Rev. 0,ATTACHMENT

24) was used as an initial "Base-1 List" of potential SWEL-1 walkdowncomponents.

This list includes shared, Unit 1 and Unit 2 components;

however, only the sharedand Unit 1 components are considered part of the Unit 1 SWEL-1 Base-1 list. Additionally, theIPEEE list included some non-safety/non-seismic equipment, which were not considered to bepart of the Unit 1 SWEL-1 Base-1 list. The prior IPEEE list effectively represents the output ofEPRI guidance equipment Screening criteria's

1. 1, #2 and #3. The SWEL-1 "Base-1 List" isprovided in ATTACHMENT 1.EPRI Screening criteria

1. 4 was then used to select equipment from this "Base List." EPRIscreening criteria

1. 4 requires a representative cross-section of the following sample selection attributes:

• include a variety of systems,* Include variety of types of equipment,

• Include a variety of equipment environments,

• Include major new/replacement equipment

• Include equipment enhancements implemented in response to prior IPEEE walkdownidentified discrepancies The McGuire Unit I SWEL-1 equipment list (ATTACHMENT

2) comprised 99 components in -22different systems.

Safety and PRA significant systems are well represented within the SWEL-1equipment selection, such as Auxiliary Feedwater (CA, SA), Emergency Service Water (RN),Essential AC Power (EDG, EPC, EPE), Vital DC Power (EPQ, EPG, EPL), Solid State Protection System (IPE), Residual Heat Removal (ND), Safety-Injection (ND, NI, NV), Closed Cooling WaterSystem (KC), control room ventilation (VC, YC), Main Steam (SM, SV), Reactor Coolant (NC),and containment spray (NS) systems.

The systems and components selected for SWEL-1support the EPRI screen #3 safety functions, which are necessary to achieve safe reactorshutdown, andlor containment isolation.

Fukushima Near-Term Task Force (NTTF) Recommendation 2.3:NRC Submittal Report for Seismic Walkdowns McGuire Unit 1Page 5 of 15Rev. 1The SWEL-1 list represented equipment from each of the EPRI guidance equipment

classes, withthe exception of air compressors and motor-generator sets. McGuire does not have any SeismicCat I equipment within these two equipment classes.

The SWEL-1 lists included equipment located in -44 different plant areas/rooms locations.

The selected equipment locations represent a broad range of equipment environmental conditions (e.g. inside containment, partial outdoorexposure, electrical/mechanical penetration rooms, pipe-chases, control room, etc.). Modified, new, and/or replacement equipment comprised

>20% of the SWEL-1 list. Similarly, the SWEL-1list included some equipment which was enhanced in response to the prior IPEEE walkdowneffort.The SWEL-1 component selection further considered PRA risk significance relative to theexternal seismic event. The SWEL-1 component list included a broad sampling of components, which were identified to have a significant contribution to CDF for the external seismic event.The McGuire Unit 1 SWEL-2 spent fuel pool equipment list was developed in accordance with theEPRI guidance.

Seismic Category I structures, piping, and containment penetrations werespecifically excluded by the EPRI guidance.

The four screening criteria specified were as follows:1) Seismic Category I licensing bases,2) Spent Fuel Pool (SFP) equipment appropriate for an equipment walkdown process,3) Sample considerations represent broad population of equipment with considered sample selection attributes such as:a. represent a variety of systems,b. major new/replacement equipment,

c. variety of equipment types,d. variety of environments OR4) Equipment which could result in rapid drain down of the SFP (includes both seismicand non-seismic components and similar factors outlined in 3) above, as practical).

The SWEL-2 equipment "Base-2 List" (ATTACHMENT

3) was established based on screens #1and #2 above. Equipment was selected from the Base-2 List based on screening criteria

1. 3above, and primarily included major equipment such as the spent fuel cooling system pumps,pump motor air handling units, and heat-exchangers.

The SWEL-2 list was further supplemented based on screening criteria

1. 4 above, to includeequipment which could result in SFP rapid drain-down, as defined by the EPRI guidance.

TheSFP mechanical connections were further reviewed to ascertain whether they could present thepotential for rapid drain-down of the SFP in-the-event of postulated seismic event. Rapid drain-down is considered to be an uncontrolled and unlimited drain-down due to a postulated leakagefrom a mechanical piping/component interface.

The EPRI guidance provided a definition for SFPuncontrolled drain-down, which was seismic induced leakage which could drain SFP to within 10'of the top of the fuel within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />. Unlike the prior screening

criteria, screen #4 does notexclude non-seismic equipment.

Fukushima Near-Term Task Force (NTTF) Recommendation 2.3:NRC Submittal Report for Seismic Walkdowns McGuire Unit 1Page 6 of 15Rev. 1The McGuire Unit 1 & 2 SFP relies on passive design features to limit the amount of inventory which could be inadvertently drained.

In general, the mechanical piping interfaces below the SFPnormal water level are either equipped with siphon breakers, and/or the pipe elevation does notextend more than 2-4' below normal SFP water level. The McGuire SFP is normally aligned tothe fuel transfer canal to support the Safe Shutdown Facility Standby Make-up Pump (SBMUP).The SBMUP is periodically aligned to the spent fuel pool for testing and was considered to be apotential rapid drain-down

pathway, thus some of the associated components in the flow-path were included in the SWEL-2 Rapid Drain Down list (ATTACHMENT 3). The SWEL-2 RapidDrain Down List also included some components which could pose a rapid drain down risk duringrefueling operations (e.g. reactor cavity seal, refueling canal drains, etc.). The final SWEL-2 listwas selected based on a sampling of appropriate equipment types from the Base-2 and RapidDrain Down Lists. The SWEL-2 list is provided in ATTACHMENT 4 and was comprised of 8components.

4.0 Seismic Walkdowns and Area Walk-BysDuke Energy contracted the Shaw Group / ARES Corporation team to perform the NTTF 2.3seismic walkdowns at McGuire Nuclear Station.

The McGuire Unit 1 walkdown summary report,the component Seismic Walkdown Checklists (SWC), and the Area Walk-By Checklists (AWC)are provided in ATTACHMENT

5. Duke Energy personnel subsequently completed thewalkdown checklists for the initially inaccessible components, and these are provided inATTACHMENT 7.The Seismic Walkdowns and Area Walk-bys were conducted in accordance with the EPRIguidance outlined in EPRI Technical Report #1025286 (Reference MCC-1612.00-00-0001, Rev.0). The EPRI guidance Seismic Walkdown Check-lists (SWC)s were completed for each item onthe SWEL. The EPRI guidance Area Walk-by Check-lists (AWC)s were also completed forareas/rooms associated with SWEL equipment.

The component seismic walkdown inspections were primarily focused on the identification ofpotentially degraded component anchorage conditions, and potentially adverse seismicinteractions with surrounding SSCs. For the non-line mounted components, the visualinspections assessed whether the anchorage was degraded (e.g. bent, loose, broken, missing,corroded, localized concrete cracks).

Additionally for at least 50% of the non-line mountedcomponents, the as-built field anchorage was verified to be consistent with designdocumentation.

The Area Walk-by inspections were performed for SWEL equipment areas. The area walk-bysassessed whether other surrounding equipment in the area/room (up to -35' radius aroundSWEL component or the room containing the SWEL component) had potentially degradedanchorage, or whether the potential for adverse seismic interactions were present.

Fukushima Near-Term Task Force (NTTF) Recommendation 2.3:NRC Submittal Report for Seismic Walkdowns McGuire Unit 1Page 7 of 15Rev. 1If the Seismic Walkdown Engineers (SWEs) determined a potentially adverse seismic condition

existed, then the issue was entered into the corrective action program (CAP) to allow furtherengineering evaluation.

The CAP engineering evaluation determined whether the potentially adverse seismic condition was degraded, unanalyzed, or non-conforming to the design andlicensing bases107 Seismic Walkdown Checklists (SWC) were completed for the components listed on theSWEL. This total was comprised of 99 SWEL-1 components, and 8 SWEL-2 components.

Theoriginally accessible component walkdowns were performed by Shaw Group / ARES personnel.

Duke Energy personnel completed the remaining walkdowns for the "inaccessible" components which required a unit outage to complete (Refer to section 4.0). For the non-line mounted SWELequipment, an anchorage as-built verification was completed for 57% of the equipment withanchorage.

Additionally, a total of 53 (48 by Shaw/ARES personnel, and balance by Dukepersonnel)

Area Walk-by Checklists (AWC) were completed for the SWEL-1 scope, and 2 AWCwere completed for the SWEL-2 scope.The seismic walkdowns and walk-bys identified 32 "Potentially Adverse Seismic Conditions" which are outlined in TABLE 4-1. Refer to the respective TABLE NOTE(s) for the "CAPResolution" designation.

The potentially adverse seismic conditions were entered into theCorrective Action Program (CAP). Engineering evaluation was performed as warranted for thepotentially adverse seismic condition, and in all cases the engineering evaluation concluded thatthe condition was in conformance with the current licensing bases. In some cases work requestsor CAP ACTIONS were initiated as required to resolve minor issues (e.g. loose fastener, addgrout, etc.), and/or to enhance field equipment clearances.

Fukushima Near-Term Task Force (NTTF) Recommendation 2.3:NRC Submittal Report for Seismic Walkdowns McGuire Unit 1Page 11 of 15Rev. 1Additionally, there were 11 SWCs which documented that portions of internal electrical cabinetanchorage was concealed in-part or entirely, and the SWCs were designated to be "unknown."

The SWC for 1ETB (4 kV Essential Switchgear) was initially specified to be "unknown" due topersonnel safety concerns, thus this component internal anchorage inspection was deferred(refer to the inaccessible component section below). The remaining 10 SWCs which weredesignated "unknown" are as follows:* 6 SWCs were associated with 125 VDC vital battery distribution centers (EVDA, EVDB)and 600 VAC Essential MCCs (1 EMXA, I EMXA-1, 1 EMXB, 1 EMXB-1) in which portions ofanchors were not accessible because they were covered by structural members or theembedded "C"-channel.

Some physical equipment demolition would be required to visuallyaccess all the anchorage.

• 3 SWCs (EMXE 600 VAC MCC, 1A EDG Battery, 1A CA pump control panel) only a portionof the internal anchorage was visible, due to concealment by wires, wire-ways, or otherstructure.

A significant portion of the cabinet anchorage was visibly inspected (16 of 18bolts for EMXE, 10 of 12 fasteners for 1A EDG battery, 8 of 12 anchors for the 1A CAPump Control Panel). The anchors which could not be visually inspected are judged to bein acceptable condition based on the satisfactory condition of the visually inspected anchorage.

0 The SWC for the Turbine Driven Auxiliary Feedwater Pump (TDCAP) control panel theinternal anchorage was concealed by a sheet metal shroud. Therefore, it was not includedin the 50% anchorage check. This component inspection was limited to the visual ofinternal cabinet components to ensure they were secure, exterior perimeter inspection ofthe cabinet concrete, and for local seismic interaction concerns.

This equipment was retained on the SWEL to satisfy various sample selection attributes;

however, some physical equipment demolition would be required to visually access all theanchorage.

This equipment is located in a dry, mild environment and not exposed to anyphysical degradation mechanisms.

The SWCs and associated inspections are deemed tosatisfactorily meet the intent of the published EPRI walkdown guidance.

Based on the aggregate results of the seismic walkdowns, there were no significant anchorage deficiencies, nor licensing bases issues identified.

Based on the foregoing discussion, no further equipment walkdowns areplanned for these components.

Fukushima Near-Term Task Force (NTTF) Recommendation 2.3:NRC Submittal Report for Seismic Walkdowns McGuire Unit 1Page 12 of 15Rev. 1INACCESSIBLE COMPONENTS:

The Unit 1 components initially deemed to be inaccessible, which required a unit shutdown inorder to complete the walk-downs are listed in TABLE 4-2. These outstanding SWC andassociated AWC were completed during the McGuire Unit 1 spring 2013 refueling outage. ASWC for 1ETB was initially partially completed in the fall of 2012, and 1ETB was re-inspected toverify internal anchorage condition and configuration.

The AWC was previously completed for1 ETB and was not re-performed.

Table 4-1 was updated based on the results of these recentwalk-downs.

The potentially adverse seismic conditions were entered into the Corrective Action Program (CAP). Engineering evaluation was performed as warranted for the potentially adverse seismic condition, and in allcases the engineering evaluation concluded that the condition was in conformance with thecurrent licensing bases. In some cases work requests or CAP ACTIONS were initiated to resolveminor issues (e.g. loose fastener, add grout, etc.), update design documents, and/or to enhancefield equipment clearances.

The potential adverse conditions and their individual Problem Investigation process (PIP) trackingnumbers are listed in the Unit 1 NTTF 2.3 Seismic Walkdown Reports (ATTACHMENTs 5 and 7).6.0 IPEEE Vulnerabilities The McGuire IPEEE NRC submittal of 6/1/94 (Reference

8) concluded that there were novulnerabilities from external events. Thus, there were no identified plant changes which wouldsignificantly reduce the risk from external events.

Fukushima Near-Term Task Force (NTTF) Recommendation 2.3:NRC Submittal Report for Seismic Walkdowns McGuire Unit 1Page 13 of 15Rev. 1Table 3-3 of the 1PEEE NRC Submittal identified several enhancements to resolve minor fieldwalkdown issues (References 6, 8, ATTACHMENT 3).

Fukushima Near-Term Task Force (NTTF) Recommendation 2.3:NRC Submittal Report for Seismic Walkdowns McGuire Unit 1Page 14 of 15Rev. 17.0 Peer Review:Duke Energy contracted with the Shaw Group (Shaw) / ARES Corporation (ARES) Team toperform the NTTF 2.3 peer review for the McGuire Nuclear Station (MNS). The Peer ReviewReport for the initially accessible components is contained in ATTACHMENT

6. A supplemental Peer Review Report (ATTACHMENT

8) was performed for the initially inaccessible components, which were completed during McGuire Unit 1 spring 2013 refueling outage.The Peer Review Team consisted of three individuals (refer to Table 2-2), all of whom haveseismic engineering experience as it applies to nuclear power plants. These individuals participated in the peer review of each of the activities.

The Shaw/ARES methodology conforms to the guidance in Section 6 of EPRI 1025286.

Thepeer review covered the following:

• The selection of the SSCs included on the Seismic Walkdown Equipment List (SWEL).* A sample of the checklists prepared for the seismic walkdowns and area walk-bys.

• The licensing basis evaluations.

• The decisions for entering the potentially adverse conditions in the Corrective ActionProgram (CAP) process.* The submittal report.The peer review process for the SWEL development and the seismic walkdowns consisted of thefollowing:

• Reviewing the activity guidance in EPRI 1025286, the NEI Q&A bulletins, the NEI first-mover reports, and NRC Temporary Instruction 2515/188.

• Conducting an in-process review at the plant site, including interviews with the personnel performing the activity and reviewing in-process documentation.

• Performing an in-plant surveillance (for the walkdown activity) of a seismic walkdown andan area walk-by.* Providing in-process observations and comments to the personnel performing the activities.

• Conducting a final review of a sample of the completed documentation.

The peer review process for the licensing basis evaluations and the decisions for enteringpotentially adverse conditions into the CAP consisted of reviewing the overall review process anda sample of the licensing basis reviews.

The peer review process for the submittal reportconsisted of reviewing the draft submittal prepared by McGuire Design Engineering for licensing review. The peer review of the licensing basis evaluations resulted in some open issues;however, those issues were addressed by updating the licensing basis evaluations documented in the CAP.The conclusion of the peer review is that the MNS NTTF 2.3 seismic walkdown effort has beenconducted in accordance with the guidance in EPRI 1025286.

Comments made during the in-process review of the SWEL development and the walkdowns have been addressed satisfactorily.

In-process comments on the final walkdown

reports, the licensing basis reviews,and the submittal have also been resolved.
