Revised pages 1-15, Added ATTACHMENTS 7 & 8.Executive Summary The 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 Walkdown Guidance 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 the Nuclear Regulatory Commission's (NRC) 10CFR50.54(f) letter regarding NTTF Recommendation 2.3: Seismic. The EPRI guidance outlined requirements for personnel qualifications, selection of walkdown components, the conduct of the walkdowns, evaluation of potentially adverse conditions against the plant seismic licensing basis, and reporting requirements.

The guidance further provided check lists to document the performance of the seismic 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 walkdown results for the previously in-accessible components.

1.0 Seismic Licensing Basis Site 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, the weathered material was excavated and fill concrete was used under foundation structures, or piles 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 peak ground 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 1 building foundations on closely joined rock and slightly weathered rock and for all building elevations 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 1 Page 2 of 15 Rev. 1 System, Structure, Component (SSC) Seismic Design: All structures, systems and components required to shut down and maintain the reactor in a safe and orderly condition or prevent the uncontrolled release of excessive amounts of radioactivity have a seismic classification of Category 1 (UFSAR 3.2.1). The McGuire design complies with Regulatory Guide 1.29 for SSC seismic design requirements.

Seismic Category I SSCs are designed to maintain their functional capability in-the event of a SSE. 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 the Operating 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 Against Natural Phenomena* Duke Class A, B, C piping per ASME Section III, 1971, except for the Nuclear Service Water piping which was designed per ANSIB31.7, Class III (Reference UFSAR Table 3-5)" Duke Class A, B, C valves per ASME Section III, 1971 (Reference UFSAR Table 3-6)* Duke Class F valves per ANSI B31.1.0 (1967), Class III (Reference UFSAR Table 3-6)* Regulatory Guide 1.29, "Seismic Design Classification," Revision 3, September 1978.* IEEE Standard 344-1971, "Recommended Practices for Seismic Qualification of Class 1E Equipment for Nuclear Power Generating Station."

Fukushima Near-Term Task Force (NTTF) Recommendation 2.3: NRC Submittal Report for Seismic Walkdowns McGuire Unit 1 Page 4 of 15 Rev. 1 3.0 Selection of Equipment for the SWEL-1 and SWEL-2 Lists The 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 through #3 are as follows: 1) Seismic Category I licensing bases, 2) Exclude structures, penetrations, and piping systems 3) Equipment must perform safety function (reactor reactivity control, reactor coolant pressure control, reactor coolant inventory control, decay heat removal, containment integrity).

The EPRI screening criteria further allows major NSSS equipment inside containment 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 walkdown components.

This list includes shared, Unit 1 and Unit 2 components; however, only the shared and Unit 1 components are considered part of the Unit 1 SWEL-1 Base-1 list. Additionally, the IPEEE list included some non-safety/non-seismic equipment, which were not considered to be part of the Unit 1 SWEL-1 Base-1 list. The prior IPEEE list effectively represents the output of EPRI guidance equipment Screening criteria's

1. 1, #2 and #3. The SWEL-1 "Base-1 List" is provided in ATTACHMENT 1.EPRI Screening criteria #4 was then used to select equipment from this "Base List." EPRI screening criteria #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 walkdown identified discrepancies The McGuire Unit I SWEL-1 equipment list (ATTACHMENT

2) comprised 99 components in -22 different systems. Safety and PRA significant systems are well represented within the SWEL-1 equipment 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 Water System (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-1 support the EPRI screen #3 safety functions, which are necessary to achieve safe reactor shutdown, andlor containment isolation.

Fukushima Near-Term Task Force (NTTF) Recommendation 2.3: NRC Submittal Report for Seismic Walkdowns McGuire Unit 1 Page 5 of 15 Rev. 1 The SWEL-1 list represented equipment from each of the EPRI guidance equipment classes, with the exception of air compressors and motor-generator sets. McGuire does not have any Seismic Cat 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 outdoor exposure, 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-1 list included some equipment which was enhanced in response to the prior IPEEE walkdown effort.The SWEL-1 component selection further considered PRA risk significance relative to the external 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 the EPRI guidance.

Seismic Category I structures, piping, and containment penetrations were specifically 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 OR 4) Equipment which could result in rapid drain down of the SFP (includes both seismic and 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 #1 and #2 above. Equipment was selected from the Base-2 List based on screening criteria #3 above, 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 #4 above, to include equipment which could result in SFP rapid drain-down, as defined by the EPRI guidance.

The SFP mechanical connections were further reviewed to ascertain whether they could present the potential 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 leakage from a mechanical piping/component interface.

The EPRI guidance provided a definition for SFP uncontrolled 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 not exclude non-seismic equipment.

Fukushima Near-Term Task Force (NTTF) Recommendation 2.3: NRC Submittal Report for Seismic Walkdowns McGuire Unit 1 Page 6 of 15 Rev. 1 The 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 SFP normal water level are either equipped with siphon breakers, and/or the pipe elevation does not extend more than 2-4' below normal SFP water level. The McGuire SFP is normally aligned to the 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 a potential 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 Rapid Drain Down List also included some components which could pose a rapid drain down risk during refueling operations (e.g. reactor cavity seal, refueling canal drains, etc.). The final SWEL-2 list was selected based on a sampling of appropriate equipment types from the Base-2 and Rapid Drain Down Lists. The SWEL-2 list is provided in ATTACHMENT 4 and was comprised of 8 components.

4.0 Seismic Walkdowns and Area Walk-Bys Duke Energy contracted the Shaw Group / ARES Corporation team to perform the NTTF 2.3 seismic 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 the walkdown checklists for the initially inaccessible components, and these are provided in ATTACHMENT 7.The Seismic Walkdowns and Area Walk-bys were conducted in accordance with the EPRI guidance 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 on the SWEL. The EPRI guidance Area Walk-by Check-lists (AWC)s were also completed for areas/rooms associated with SWEL equipment.

The component seismic walkdown inspections were primarily focused on the identification of potentially degraded component anchorage conditions, and potentially adverse seismic interactions with surrounding SSCs. For the non-line mounted components, the visual inspections 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 mounted components, the as-built field anchorage was verified to be consistent with design documentation.

The Area Walk-by inspections were performed for SWEL equipment areas. The area walk-bys assessed whether other surrounding equipment in the area/room (up to -35' radius around SWEL component or the room containing the SWEL component) had potentially degraded anchorage, 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 1 Page 7 of 15 Rev. 1 If 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 further engineering evaluation.

The CAP engineering evaluation determined whether the potentially adverse seismic condition was degraded, unanalyzed, or non-conforming to the design and licensing bases 107 Seismic Walkdown Checklists (SWC) were completed for the components listed on the SWEL. This total was comprised of 99 SWEL-1 components, and 8 SWEL-2 components.

The originally 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 SWEL equipment, an anchorage as-built verification was completed for 57% of the equipment with anchorage.

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

Area Walk-by Checklists (AWC) were completed for the SWEL-1 scope, and 2 AWC were 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 "CAP Resolution" designation.

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 all cases the engineering evaluation concluded that the condition was in conformance with the current licensing bases. In some cases work requests or CAP ACTIONS were initiated as required to resolve minor issues (e.g. loose fastener, add grout, 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 1 Page 11 of 15 Rev. 1 Additionally, there were 11 SWCs which documented that portions of internal electrical cabinet anchorage 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 to personnel safety concerns, thus this component internal anchorage inspection was deferred (refer to the inaccessible component section below). The remaining 10 SWCs which were designated "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 of anchors were not accessible because they were covered by structural members or the embedded "C"-channel.

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

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

A significant portion of the cabinet anchorage was visibly inspected (16 of 18 bolts for EMXE, 10 of 12 fasteners for 1A EDG battery, 8 of 12 anchors for the 1A CA Pump Control Panel). The anchors which could not be visually inspected are judged to be in 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 the internal anchorage was concealed by a sheet metal shroud. Therefore, it was not included in the 50% anchorage check. This component inspection was limited to the visual of internal cabinet components to ensure they were secure, exterior perimeter inspection of the 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 the anchorage.

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

The SWCs and associated inspections are deemed to satisfactorily 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 are planned for these components.

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

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

The AWC was previously completed for 1 ETB and was not re-performed.

Table 4-1 was updated based on the results of these recent walk-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 all cases the engineering evaluation concluded that the condition was in conformance with the current licensing bases. In some cases work requests or CAP ACTIONS were initiated to resolve minor issues (e.g. loose fastener, add grout, etc.), update design documents, and/or to enhance field equipment clearances.

The potential adverse conditions and their individual Problem Investigation process (PIP) tracking numbers 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 no vulnerabilities from external events. Thus, there were no identified plant changes which would significantly reduce the risk from external events.

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

Fukushima Near-Term Task Force (NTTF) Recommendation 2.3: NRC Submittal Report for Seismic Walkdowns McGuire Unit 1 Page 14 of 15 Rev. 1 7.0 Peer Review: Duke Energy contracted with the Shaw Group (Shaw) / ARES Corporation (ARES) Team to perform the NTTF 2.3 peer review for the McGuire Nuclear Station (MNS). The Peer Review Report 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 have seismic 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. The peer 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 Action Program (CAP) process.* The submittal report.The peer review process for the SWEL development and the seismic walkdowns consisted of the following:

• 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 and an 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 entering potentially adverse conditions into the CAP consisted of reviewing the overall review process and a sample of the licensing basis reviews. The peer review process for the submittal report consisted 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 been conducted 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.
