ENGINEERING REPORT NO. EA12-021 JENERCON Lc:.,- E aldo*./* REVISION I PAGE 4 OF 42 Fukushima Near-Term Task Force Recommendation 2.3 Seismic Walkdown 1.0 SCOPE AND OBJECTIVE This report documents the results of the seismic walkdown effort at the Omaha Public Power District (OPPD) Fort Calhoun Nuclear Station, for resolution of the Fukushima Near Term Task Force (NTTF) Recommendation 2.3: Seismic.

The objective of the walkdown effort is to provide response to the Title 10 of the Code of Federal Regulations, Section 50.54(f) letter (10 CFR 50.54(f)) issued by the Nuclear Regulatory Commission (NRC) on March 12, 2012 (Reference [10.1]). US nuclear power plants are "required to perform seismic walkdowns to identify and address degraded, non-conforming or unanalyzed conditions and to verify the current plant configuration with respect to the current seismic licensing basis". The Nuclear Energy Institute (NEI), through the Electric Power Research Institute (EPRI), prepared industry guidance to assist licensees in responding to this NRC request. During the walkdowns, a sample of components and areas of the plant are examined to identify potentially adverse seismic conditions, within the guidelines and parameters provided in the EPRI report 1025286 "Seismic Walkdown Guidance for Resolution of Fukushima Near-Term Task Force Recommendation 2.3: Seismic", dated June 2012 (Reference [10.2]) and endorsed by the NRC on May 31, 2012. This report will be referred to as the "EPRI Guidance"for the remainder of this document. Omaha Public Power District (OPPD)

Fort Calhoun Nuclear Station (FCNS) has committed to using this NRC endorsed guidance as the basis for the walkdowns and this report.

The sample of components selected for walkdown inspection must be suitably diverse, be located in a variety of environments, include items needed to safely shutdown the reactor, maintain containment integrity, and avoid unanticipated rapid drain-down of the spent fuel pool. The walkdowns primarily focus on equipment anchorage, seismic spatial interaction, seismically induced fire and seismically induced flood.

Ef** daiREVISION 1 PAGE 5 OF 42 Fukushima Near-Term Task Force Recommendation 2.3 Seismic Walkdown Section 6.0 describes the equipment and component selection process. The selected sample of components constitutes the Seismic Walkdown Equipment List (SWEL). In addition to seismic equipment/component walkdowns (SWD), "area walk-bys" were performed to ensure that there were no other potentially adverse seismic conditions in an approximate 35 foot radius surrounding each component on the SWEL. The seismic walkdown teams consisted of two seismic walkdown engineers (SWE). In cases where multiple SWEL items were located in the same room/area of the plant, a single area walk-by was conducted for those items.

The results of the seismic walkdowns and walk-bys are documented on the Seismic Walkdown Checklists (SWC) and Area Walk-by Checklists (AWC). Any potentially adverse seismic conditions discovered during the walkdowns and identified on the SWC's or AWC's, that could not readily be shown to meet the Current Licensing Basis (CLB), were entered into the plant's Corrective Action Program (CAP) for documentation, evaluation and resolution. Description of the walkdown process is provided in more detail in Section 7.0; results are provided in Attachments 11.2, 11.3, 11.4.

Licensing Basis Evaluations (LBEs) were performed as part of the resolution of the Condition Reports (CR) that were initiated to document potentially adverse seismic conditions. The LBE process is described in more detail in Section 8.0; results of the evaluations are summarized in Attachment 11.4.

A Peer Review team was formed to review all aspects of the effort, including the development of the SWEL, the consideration of vulnerabilities identified in the 1990's under the Individual Plant Examination of External Events (IPEEE) program, the performance of SWEs during walkdowns and area walk-bys, the Licensing Basis Evaluation process, and this Submittal Report. The Peer Review process is described in more detail in Section 9.0; results are included in Attachments 11.6 and 11.7.

SUMMARY

2.1 SAFE SHUTDOWN EARTHQUAKE The Fort Calhoun Station is a pressurized water reactor (PWR) located on the west bank of the Missouri river, .approximately 19.4 miles north of Omaha, Nebraska. The plant site is underlain by 65 to 75 feet of unconsolidated alluvial and glacial deposits, largely loose to moderately compact silty sand, and denser sands and gravels resting on sedimentary rock. The plant buildings are supported by a system of pipe piles driven to bedrock. The soil around the piles under Seismic Category I structures was compacted by vibroflotation to prevent liquefaction under Maximum Hypothetical Earthquake (Safe Shutdown Earthquake) loading.

The foundation mat for the Containment and Auxiliary buildings is an integral unit supported on piles. The Intake Structure and Turbine Building are on separate foundations, each supported on piles. The plant grade elevation is 1004 feet.

The primary sources of the plant's seismic licensing basis information are the Updated Safety Analysis Report (USAR), Appendix F (Reference [10.3]), and the Plant Level Design Basis Document (PLDBD), PLDBD-CS-51 (Reference [10.4]). The USAR describes the Design Earthquake (DE), also referred to as Operating Basis Earthquake (OBE), and the Maximum Hypothetical Earthquake (MHE), also referred to as Safe Shutdown Earthquake (SSE) and Design Basis Earthquake (DBE).

FCNS was licensed in accordance with the draft criteria set forth in the 70 General Design Criteria for Nuclear Power Plant Construction, published for comment in the Federal Register (32 FR 10213) on July 11,1967.

The Safe Shutdown Earthquake (SSE) for the site is 0.17g acting in the horizontal direction and two-thirds of 0.17g acting in the vertical direction simultaneously, in combination with the primary steady state stresses. Total stresses are limited so that

The ground response spectrum of the SSE (MHE) is shown in Figure 1. The spectrum conforms to the average spectra developed by Housner (Reference [10.11]) for frequencies higher than about 0.33 Hz. The spectra for frequencies lower than about 0.33 Hz were prepared utilizing data presented by Newmark (Reference [10.12]).

The damping factors (percent of critical) that were used in the design of SSC's range from 0.5% for vital piping systems to 7% for framed concrete structures. Damping ratio for bolted steel assemblies and for concrete structures supporting the reactor vessel or steam generator was 2%.

in combination with the primary steady-state stresses. Total stresses are maintained within the allowable working stress limits accepted as good practice and, where applicable, set forth in the appropriate design standards, such as the ASME Boiler and Pressure Vessel Code, USAS B31.1 (1967), USAS B31.1 (1955) for Reactor Coolant loop piping, and B31.7 (1968) Codes for Pressure Piping, ACI 318-63 Building Code Requirements for Reinforced Concrete, and AISC Specification for the Design and Erection of Structural Steel for Buildings. In addition, Class I SSC's have been designed such that seismic stresses resulting from the response to the Maximum Hypothetical Earthquake (ground acceleration of 0.17g horizontal and two-thirds of 0.17g vertical, acting simultaneously), in combination with the primary steady-state stresses, are limited so that the function of the SSC's is not impaired in a manner that would disrupt the safe and orderly shutdown of the plant. Seismic qualification of Class I electrical equipment conforms to IEEE 344-1975. Components of the Reactor Protective System and the Engineered Safeguards Actuation System are qualified per IEEE 344-1971 "Guide for Seismic Qualification of Class 1E Electrical Equipment for Nuclear Power Generation Stations".

The general Method of analysis for Class 1 SSC's can be described as follows:

" Determine the natural frequency of vibration of the structure or component

• Select the appropriate Amplified Floor Response Spectrum (ARS, currently called In-Structure-Response-Spectrum, or ISRS) or Ground Spectrum, depending on support elevation and/or location

,, r REVISION I PAGE 12 OF 42 Fukushima Near-Term Task Force Recommendation 2.3 Seismic Walkdown 3.0 Seismic Walk-down Program Implementation Approach OPPD has committed to conduct and document seismic walkdowns for resolution of NTTF Recommendation 2.3: Seismic, in accordance with the EPRI Guidance. OPPD contracted with ENERCON Services, Inc., for supplementary engineering and management resources.

A team of individuals, Mr. Marvin Morris and Mr. Steve Skubey, equipped with knowledge of plant systems and components, were selected to develop the Seismic Walkdown Equipment List (SWEL). Two SWELs were developed: SWEL 1 and SWEL 2.

SWEL 1 consists of a sample of equipment related to safe shutdown of the reactor and maintaining containment integrity; SWEL 2 consists of items related to the Spent Fuel Pool, as described in the EPRI Guidance.

Personnel responsible for performing the walkdowns and AWCs successfully completed training for the NTTF Recommendation 2.3: Seismic. The Seismic Walkdown Engineers who are certified by SQUG were not required to complete the NTTF training, but were trained on the differences between the USI A-46 and NTTF 2.3: Seismic programs. The team of Seismic Walkdown Engineers (SWEs) who performed the walkdowns were Mr.

Kevin Bessell, Mr. Alex Smerch, and Mr. John Kao. The majority of the walkdowns were performed by Mr. Smerch and Mr. Kao. Mr. Bessell took over the role left vacant by Mr. Kao to complete the remaining walkdowns with Mr. Smerch. Plant personnel, namely Russ Placke, Ashwin Patel and Jim Carlson, also assisted in performing walkdowns. All SWEs have some if not extensive experience in seismic design and qualification of nuclear power plant SSC's. It was considered important to the project to ensure that any given walkdown team would be comprised with an experienced seismic engineer and one less experienced engineer. Qualifications of the seismic walkdown team members are provided in Section 4.0.

.... .. .. I -, Ew doi REVISION I PAGE 13 OF 42 Fukushima Near-Term Task Force Recommendation 2.3 Seismic Walkdown Seismic Walkdown Checklists (SWC's) and Area Walk-by Checklists (AWC's) were prepared in advance of the walkdowns. Packages were assembled into folders that included related information, such as location of equipment, anchorage drawings, in-structure response spectra information, calculations, and previously performed qualifications under earlier programs (refer to Section 5.0), if available.

Walkdowns were performed for all accessible components on the combined SWEL (SWEL 1 + SWEL 2). During the walkdowns, SWC's were completed for each component on the SWEL, and AWC's were completed for each area within an approximate 35 foot radius of the component. Walkdowns were tracked by component number and AWC's by location. Details of the SWC's and AWC's are provided in Section 7.0.

The SWCs and AWCs were given one of three status marks "Y" for Yes (walkdown is completed), "N" for No (walkdown has not been performed), or "U" for Uncertain (walkdown has been performed however more information is required and item has been deferred). When feasible, inaccessible items were replaced by alternate, accessible items, and the SWEL was revised accordingly. Such changes were reviewed by the SWEs, Equipment Selection Personnel and the Peer Review team.

Potentially adverse seismic conditions that were identified in the walkdowns were either evaluated under a Licensing Basis Evaluation or entered directly into the plant's corrective action program (CAP) for further evaluation. A summary of the potentially adverse seismic conditions is provided in Attachment 11.4.

A Peer Review was conducted for each activity, including this submittal report. The Peer review activity is described in detail in Section 9.0. Qualifications of the Peer Review team are provided in Section 4.0.

plant-specific seismic vulnerabilities were identified at many plants. In this context, "vulnerabilities" refers to conditions found during the IPEEE program related to seismic anomalies, outliers, or other findings.

IPEEE Reviewers (see Section 4.0) reviewed the IPEEE Report (Reference [10.25])

and supporting documentation to identify items determined to present a seismic vulnerability by the IPEEE program. IPEEE Reviewers then reviewed additional plant documentation to identify the eventual resolutions to those seismic vulnerabilities not resolved by the completion of the IPEEE program.

During the 1980's, the NRC initiated an Unresolved Safety Issue (USI) A-46 under Generic Letter No. 87-02 (Reference [10.6]), to review the seismic adequacy of equipment in certain operating nuclear power plants with respect to seismic criteria not in use at the time when these plants were licensed. FCNS was identified as one of the A-46 plants which must be reviewed. The vulnerabilities that were then identified under the IPEEE program were also incorporated as outliers under the USI A-46 program.

OPPD joined the Seismic Qualification Utility Group (SQUG) which published the Generic Implementation Procedure, Revision 2 (GIP-2) (Reference [10.17]) for evaluating these plants and equipment. The NRC accepted the SQUG procedure for resolving USI A-46 in Supplementary Safety Evaluation Report No.2 (SSER No.2)

(Reference [10.18]). OPPD used GIP-2 in its entirety, including the clarifications, interpretations and exceptions identified in SSER No.2, as clarified by the August 21, 1992 SQUG letter (Reference [2.19]), to evaluate the seismic adequacy of selected safe shutdown equipment in the Fort Calhoun Station (Reference [2.20]).

. **:**:'-*.*Tp*;*,1a*REVISION 1 PAGE 24 OF 42 0*A crttfb"V IIII Fukushima Near-Term Task Force Recommendation 2.3 Seismic Walkdown 6.0 Seismic Walk-down Equipment List Development The process used to select the items to be included in the seismic walkdown equipment list (SWEL) is described in detail in the EPRI Guidance, Section 3: Selection of SSCs. In general, the Ft. Calhoun SWEL is comprised of two groups of items, one of which is a sample of components from the USI A-46 safe shutdown equipment list (SSEL), the Ft.

Calhoun IPEEE list, insights from the Ft. Calhoun PRA, and review of plant modifications completed since the USI A-46 report was completed (termed SWEL 1) and the other is a sample of components associated with the spent fuel pool (termed SWEL 2).

The equipment list used as a starting point for development of the SWEL 1 is the base list, or BL 1. The base list used at FCNS is the Safe Shutdown Equipment List (SSEL) that was developed to address the NRC Unresolved Safety Issue (USI) A-46, "Seismic Qualification of Equipment in Operating Plants" which employed the guidance provided in Revision 2 of the Generic Implementation Procedure (GIP) and NRC Supplemental Safety Evaluation Report No. 2. The SSEL was developed in the 1990's and, to ensure that the safe shutdown paths used as a basis for the list remained valid, a review of the Design Basis Documents (DBDs) for safe shutdown systems was performed to identify changes to the systems since the SSEL was developed. Any new or changed equipment was added to BL 1.

The selection of equipment for the seismic walkdown is based on the USI A-46 Safe Shutdown Equipment List from EA 96-017(Reference [2.26]) and the IPEEE Component List from the IPEEE Report (Reference [2.25]). Screening of these lists is based on the requirements provided in the EPRI Guidance. In accordance with the EPRI Guidance, Seismic Category I structures, containment penetrations, and Seismic Category I piping systems were not included in the SSC bucket from which the SWEL 1 components were selected. This selection process is intended to comply with the request in the NRC

6.1 SAMPLE OF REQUIRED ITEMS FOR THE FIVE SAFETY FUNCTIONS The selection of equipment for the seismic walkdown was based on the five safety functions identified in the EPRI Guidance:

1. Reactor reactivity control

2. Reactor coolant pressure control

3. Reactor coolant inventory control

4. Decay heat removal

5. Containment function The SWEL 1 was developed by applying the following five sample selection attributes, defined in the EPRI Guidance, Section 3, to BL 1. The method of application is summarized below for each attribute:

• A variety of types of systems Sample items are selected to represent a broad range of frontline and support systems included on the SSEL.

• Maior new and replacementequipment A review of the system DBDs was performed to identify major new or replacement equipment installed within the last 20 years. A sample of these items is included on SWEL 1.

" A variety of types of equipment At least one item from each of the classes of equipment listed in EPRI Guidance, Appendix B: Classes of Equipment was included in SWEL 1 to

........ E C.-,a REVISION 1 PAGE 26 OF 42 Fukushima Near-Term Task Force Recommendation 2.3 Seismic Walkdown provide a sample selection of a variety of equipment types. No items are specifically listed in the Ft. Calhoun SSEL for Classes 11, 12, and 13. For these three classes no items are included on SWEL 1.

• A variety of environments Sample items were selected from different locations in the plant to include various environments (hot, cold, dry, wet) and inside and outside installations.

• Equipment enhanced due to vulnerabilitiesidentified during the IPEEE program The IPEEE program documentation was reviewed to determine equipment that had been modified or otherwise enhanced to reduce IPEEE vulnerabilities. A sample of these items is included on SWEL 1.

An additional consideration for the development of SWEL 1 is the equipment availability for inspection due to protected train restrictions during plant operation. The SWEL 1 items were selected from a single train (train A, where possible) and the walkdowns were scheduled to be accomplished within a single week to ensure accessibility. To ensure that risk significant items were included, insights from the Ft. Calhoun Probabilistic Risk Assessment (PRA) were considered.

The Fort Calhoun Station Probabilistic Risk Assessment (PRA) model includes only simplified modeling of a potential seismic initiating event. The simplified seismic model is used to support plant configuration risk assessments. It is not equivalent to a seismic PRA, and does not meet Regulatory Guide 1.200 (Reference [2.27]) with respect to modeling of seismic events. The simplified seismic model is based on a hypothetical seismic event (nominally 0.1g) that is assumed to result in failure of selected equipment that is susceptible to failure at or near the assumed g-level. The model assumes that the seismic event results in unrecoverable loss of off-site power, failure of equipment in the Turbine Building (including Auxiliary Feedwater Pump FW-54), failure of the diesel-

Using the existing PRA model, a list of potential seismic event accident sequences (i.e.,

cut-sets) was generated. The list of importance measures for basic events appearing in the seismic event cut-sets were sorted based on the "Risk Achievement Worth, RAW" importance measure. The equipment with the highest importance according to this approach is listed below:

" Diesel Generators (including inlet/exhaust dampers and fuel oil transfer pumps)

• Station Batteries

• Various 4160V Breakers

• Air-Operated Auxiliary Feedwater Valves

• 480V Buses

• Auxiliary Feedwater Pumps FW-10 & FW-6 (including associated equipment) 6.2 SPENT FUEL POOL (SFP) ITEMS A base list (BL 2) was developed by reviewing the spent fuel pool (SFP) cooling and inventory related systems for all safety-related, Seismic Category I equipment and reviewing the systems whose failure could result in rapid drain-down of the SFP to within 10' above the stored fuel. Rapid drain-down is defined as lowering of the water level to the top of the spent fuel assemblies within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> after an earthquake. A sample of the Seismic Category I systems components were selected for inspection consistent with the SWEL 1 methods defined previously to create SWEL 2.

The method for selection of SWEL 2 SFP rapid drain-down items described in the EPRI Guidance is difficult to implement. When rapid drain-down items are identified, it is not clear what actions are required particularly if items are placed on SWEL 2. Rapid drain-

E- N R ONENGINEERING REPORT NO. EA12-021

,-REVISION I PAGE 28 OF 42 Fukushima Near-Term Task Force Recommendation 2.3 Seismic Walkdown down would typically involve piping failure; however, the walkdown guidance does not include piping in the scope. In addition, the rapid drain-down considerations in the EPRI Guidance, such as pool sloshing evaluations, boil-off, leak size, etc., are not sufficiently defined for implementation as part of the walkdown / SWEL development process.

SWEL 1 and SWEL 2 items were combined to form the SWEL. Generally speaking, all major components (e.g., tanks, heat exchangers, and pumps) needed for safe shutdown, following a seismic event and accompanied by a loss of offsite power (LOOP), were selected.

The SWEL was developed in the form of a spreadsheet, which allowed for manipulation/sorting of data and cross-referencing to build summary tables. The SWEL spreadsheet includes the following information:

1. Sequential item number (used to develop the SWC ID #)

2. A-46 Equipment Box (where provided)

3. Component ID

4. Equipment Class (from GIP)

5. Item Description

6. System Designator

7. Location (Room)

8. Floor Elevation

9. Equipment Location

10. Power source (if applicable)

The associated lists from the spreadsheet, BL 1, BL 2, and the combined SWEL can be found in Attachment 11.1. It shall be noted that the information (equipment description, elevation, location, etc.) provided in the base lists (BL1, BL2) is what is provided exactly

Having obtained assurance from the SWEL development team and the Peer Review team that the SWEL attributes contained in the EPRI Guidance were not compromised, a small number of components that were inaccessible were either removed from the SWEL or replaced by alternate components.

The initial set of walkdowns were conducted from August 13 th through August 2 9 th, 2012, and focused on anchorages, seismic spatial interactions, and other potentially adverse seismic conditions, such as bolts in degraded or non-conforming conditions, extensive corrosion, absence of, or, inadequate hardware, cracked concrete, corrosion of weld and/or base metal, etc. Remaining walkdowns of deferred items which are discussed in Revision 0 were concluded on March 2 9 th, 2013.

In addition to the general inspection requirements, at least 50% of SWEL items with anchorage were required to be verified that their anchorage is consistent with plant documentation. A total of 96 items were identified on the SWEL for inspection. Of the 96 items on the SWEL, 68 items had anchorage that was not considered in-line.

Anchorage configuration verification was performed on 39 items, which is greater than 50% of the items with anchorage not considered in-line. There are 96 SWCs provided in Attachment 11.2. It shall be noted that the information provided on the SWCs relative to equipment identification, location, description and floor elevation was input as provided in the FCNS document management system, Asset Suite.

Area Walk-Bys were performed in conjunction with the walkdowns of each item. All areas/rooms containing equipment on the SWEL were included in the AWCs. Since

It shall be noted that the floor elevation identified on the AWCs corresponds to the elevation from which the inspections were performed.

In cases where the SWEs identified a potentially adverse seismic condition, the condition was identified on the SWC and/or AWC and a Licensing Basis Evaluation was performed.

If the identified condition is consistent with existing seismic documentation associated with that item, then no further action is required. Ifthe identified condition cannot easily be shown to be consistent with existing seismic documentation, or no seismic documentation exists, then the condition is entered into the CAP.

Of the 70 identified potentially adverse seismic conditions, 70 LBEs were performed.

Each LBE performed is documented consistently, and included in Attachment 11.5. The results of these LBEs with respect to the associated potentially adverse seismic conditions are summarized in Attachment 11.4. A total of 21 potentially adverse seismic conditions evaluated using a LBE were dispositioned and require no further action, whereas 49 required CAP entry. It shall be noted that some of the potentially adverse seismic conditions are provided on the same CAP entry. The LBEs that were dispositioned were the result of inadequate anchorage configuration documentation at the time of the inspections. The SWE team documented as-built anchorage information as sketches on the checklists for further verification against plant documents.

The following Licensing Basis Evaluations provided below are worth noting. Refer to specific LBEs provided in Attachment 11.5 for more information on the condition.

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

Seismically insignificant unusual conditions

• Potentially adverse seismic condition that does not pass a LBE

• Potentially adverse seismic condition that bypasses a LBE A total of 36 CRs were written relative to potentially adverse seismic conditions identified. The CR numbers, current status, and resolution (where applicable and available) are summarized for these potentially adverse seismic conditions in 1.4.

The peer review team confirmed that the SWE walkdown team performed the seismic walkdowns and area walk-bys as described in Section 4 of the EPRI Guidance. A minimum of 10-25% of the SWCs and AWCs were reviewed for consistency and accuracy. The majority of the peer reviews occurred at the start of the walkdowns, and the reviewers were able to provide comments at the early stages of the process. This helped to ensure consistency and confirm that walkdowns were being performed in accordance with all the requirements of the EPRI Guidance.

All potentially adverse seismic conditions were entered into the plant's CAP program for further review and disposition. The review team verified the decisions for identifying such conditions as sound, and the dispositions were conducted in accordance with the plant's current license basis (CLB).

A peer review was completed of the licensing basis evaluations provided in Attachment 11.5. Within these licensing basis evaluations, CRs were generated for maintenance issues to replace missing bolts, nuts or remove items for housekeeping issues, or to provide further, detailed resolution of the potentially adverse seismic condition. The remaining licensing basis evaluations were created to document potentially adverse seismic conditions that were immediately entered into the CAP for detailed evaluation and investigation. The peer review of these LBEs ensured that all the information provided from the walkdown team to the licensing basis evaluation team member provided enough detail for accurate and timely resolution.

The peer review team was provided with an early draft of this submittal report for peer review. The peer review team verified that the submittal report met the objectives and requirements of Enclosure 3 to the 50.54(f) Letter, and documented the NTTF 2.3

9.2 PEER REVIEW RESULTS

SUMMARY

Peer Review of the seismic walkdowns and area walk-bys were conducted by Ashwin Patel and David Haas, who have extensive experience in seismic engineering as applied to nuclear power plants. The peer review team reviewed the walkdown packages (checklists, photos, drawings etc.) and ensured that the SWCs and AWCs were completed in accordance with the EPRI Guidance. The checklists were selected at random and 25 out of 96 SWC forms (26% of total) and 20 of 33 AWC forms (61% of total) were reviewed.

2. Is the anchorage free of bent, broken, missing or loose hardware? Y[ NEil Ut-] N/Ai-I Anchorage consists of welds between the bus frame and a metal plate embedded in the concrete floor on both the front and back sides of the bus. Each cubicle has 2 plug welds on the front side and 3 plug welds on the back side with the exception of the 2 center cubicles which have no welds in the back. Upon examination it was observed that for some of the welds there was not complete penetrationor there were gaps between the weld material and the base of the bus. Portions of the base of the cabinent were not completely observable due to a fire resistantcoating obstructing view. Below is a summary of the deficient welds for each cubicle:

Cubicle 500 - 50% of contact with bus in one of the back welds.

Cubicle 502 - 70% of contact with bus in one of the back welds.

Cubicle 503 - 50% of contact with bus in one of the front welds.

Cubicle 503 - Back of cubicle is covered by fire-resistantcoating, but SEWS for IB3C shows that there is no anchorageexisting underneath.

Cubicle 504 - 30% of contact with bus in one of the front welds.

Cubicle 504 - Back of cuble is covered by fire-resistantcoating, but SEWS for 1B3C shows that there is no anchorage existing underneath.

Cubicle 506 - 95% of contact with bus in front left weld.

Cubicle 506 - 50% of contact with bus in front right weld.

Cubicle 506 - Unknown amount of weld in back cubicle as it is covered by fire-resistantcoating.

Review of SEWS package for IB3C noted that the quality of welds were inspected by a weld specialistas cross referenced in the SEWS package of 1A3. Therefore the welds are judged to be acceptable.

The welds that are not visible arejudged to be adequate based on the consistency of welds observed in the remaining cubicles and as noted in the SEWS report.

3. Is the anchorage free of corrosion that is more than mild surface YX Nt] Ut] N/At]

oxidation?

There appears to be mild oxidation on some of the welds but no loss of material.

4. Is the anchorage free of visible cracks in the concrete near the Y[ Nt:] Ut] N/At]

anchors?

There were no cracks observed on the concrete surface.

6. Based on the above anchorage evaluations, is the anchorage free of YZ N[] UD]

potentially adverse seismic conditions?

Interaction Effects

7. Are soft targets free from impact by nearby equipment or structures? Y[K N[] U-I N/AD--

The only nearby equipment is a transformerwhich is connected to the bus and therefore could not move out of phase with the bus and cause damage during an earthquake.

8. Are overhead equipment, distribution systems, ceiling tiles and lighting, YZ NEI UDI N/ADl and masonry block walls not likely to collapse onto the equipment?

All overhead equipment inlcuding lighting and cable trays are well supported.

9. Do attached lines have adequate flexibility to avoid damage? Y[ NF-] UD- N/AD All attached lines either have nearby 90 degree elbows giving them flexibility or are flexible cables themselves.

10. Based on the above seismic interaction evaluations, is equipment free Y[ NiD UFD of potentially adverse seismic interaction effects?

Other Adverse Conditions

11. Have you looked for and found no other seismic conditions that could YN NEI UD adversely affect the safety functions of the equipment?

There were some sheet metal screws observed that were not screwed to anything but a single piece of sheet metal and therefore not providing any function, but these were deemed not to be a seismic concern as they have negligible mass.

6. Based on the above anchorage evaluations, is the anchorage free of YZ Niln U[I potentially adverse seismic conditions?

Refer to question #2.

Interaction Effects

7. Are soft targets free from impact by nearby equipment or structures? YZ NDi Ur N/AD:

There are overhead light fixtures in the vicinity with uncaged fluorescent bulbs. The light fixture is well overhead and does not pose a credible interaction with the equipment. The light bulb is not a signficant source since it is brittle with an extremely small mass relative to the cabinet.

The light fixtures also have open S-hooks, however the S-hooks have a wire tieing them closed, therfore providing redundancy.

8. Are overhead equipment, distribution systems, ceiling tiles and lighting, YX NDI UD N/AD and masonry block walls not likely to collapse onto the equipment?

Cable tray is supportedoverhead. The cable tray supports are well supportedand there is sufficient vertical clearancebetween the top of the cabinet and the bottom of the cable tray support. There is also piping overhead which is well supported and brace.

9. Do attached lines have adequate flexibility to avoid damage? YZ ND] UD-- N/AD-Flexible cables feed into the top of the cabinet Conduit is also connected to the top of the cabinet and contains multiple bends to promote flexibility.

10. Based on the above seismic interaction evaluations, is equipment free YN NDý UDl of potentially adverse seismic interaction effects?

Other Adverse Conditions

11. Have you looked for and found no other seismic conditions that could YEK NEI UDý adversely affect the safety functions of the equipment?

Interconnectingbolts were missing which connect panels on IB4A with 69/1IB4A. It appears as if the bolts were there once. There are 3 bolts one side and 4 the other side remaining,and the stabilityand connection is judged to be adequate. CR 2013-07194 was issued to resolve the issue.

Instructions for Completing Checklist This checklist may be used to document the results of the Seismic Walkdown of an item of equipment on the SWEL. The space below each of the following questions may be used to record the results of judgments and findings. Additional space is provided at the end of this checklist for documenting other comments.

Anchorage

1. Is the anchorage configuration verification required (i.e., is the item one Y[-D NO of the 50% of SWEL items requiring such verification)?

2. Is the anchorage free of bent, broken, missing or loose hardware? YO NDI UD N/A[D The anchorageconsists of 3 rows of 2 plug welds on either side of each cubicle attaching the base of each cubicle to embedded steel in the floor.

The plug weld on cubicle 1A3-3 middle row is in poor condition and appearsto be missing weld. Review of SEWS documentation for 1A3 confirms that the welds are acceptable based on previous weld inspections.

Due to breaker obstruction,only 5 plug welds were visible for cubicles 1A3-5, 6, 7, 9, 10, 11, 12, 13, 15 and 20.

Plates were obstructing the view of 4 plug welds in cubicles 1A 1- 1A3 and 1A3-4.

Based on informationprovided in the SEWS package the conditions noted above are judged to be adequate. As provided in the SEWS package, the loading conditions are minimal with a lowest safety factor of 4 when analyzed against 5 plug welds. Although only 2 plug welds were visible on 1A 1-13 and 1A 3-4, these welds are judged to be adequate based on the extent and consistency encountered during inspection.

3. Is the anchorage free of corrosion that is more than mild surface YO ND-1 ur N/AD--

oxidation?

Minor oxidation noted in the vicintiy of the plug welds.

6. Based on the above anchorage evaluations, is the anchorage free of Y[ NE] Uil potentially adverse seismic conditions?

Interaction Effects

7. Are soft targets free from impact by nearby equipment or structures? YN NEI U[-I N/AD-There are overhead light fixtures in the vicinity with uncaged fluorescent bulbs. The light fixture is well overhead and does not pose a credible interaction with 1A3. The light bulb is not a signficant source since it is brittle with an extremely small mass relative to the cabinet.

8. Are overhead equipment, distribution systems, ceiling tiles and lighting, YZ NEI U-- N/A--

and masonry block walls not likely to collapse onto the equipment?

Cable tray is supported overhead. The cable tray supports are well supportedand there is sufficient vertical clearance between the top of the cabinet and the bottom of the cable tray support. There is also piping overhead which is well supported and brace.

9. Do attached lines have adequate flexibility to avoid damage? YN N[:] U0 N/AD-1 Flexible cables feed into the top of the cabinet Conduit is also connected to the top of the cabinet and contains multiple bends to promote flexibility.

Anchorage

1. Is the anchorage configuration verification required (i.e., is the item one Y[K NE of the 50% of SWEL items requiring such verification)?

2. Is the anchorage free of bent, broken, missing or loose hardware? YO NE! U[] N/A[]

The anchorageof the bus consists welds between the bus frame and an embedded metal plate in the concrete floor. All 21 cubicles have at minimum six -1/2" welds between the frame and the embed plate, with the exception of cubicles IA4-2 and 1A4-7 having only 4 welded points.

3. Is the anchorage free of corrosion that is more than mild surface YO NO! ur] NIAEJ oxidation?

There appearsto be mild oxidation on some of the welds but no loss of material.

4. Is the anchorage free of visible cracks in the concrete near the YZ NEI U-] N/A'-

There were no cracks observed on the concrete surface.

5. Is the anchorage configuration consistent with plant documentation? YZ NE- ur] N/Ar-(Note: This question only applies if the item is one of the 50% for which an anchorage configuration verification is required.)

Anchorage was verified againstSEWS Package for 1A4 Rev. 0.

Only 2 welds in cubicle 1A4-21 were visible but given that the SEWS Package conservatively excludes some of the welds from its anchorage analysisand still has significantmargin for the seismic analysis, this was not deemed to be a concern.
