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.Anchoragae

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

Yes Yes 2. Is the anchorage free of bent, broken, missing or loose hardware?3. Is the anchorage free of corrosion that is more than mild surface oxidation?

Yes 4. Is the anchorage free of visible cracks in the concrete near the anchors?Yes 5. Is the anchorage configuration consistent with plant documentation? (Note: This question only applies if the item is one of the 50% for which an anchorage configuration verification is required.)

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

PANEL Interaction Effects 7. Are soft targets free from impact by nearby equipment or structures?

Yes Ductwork stiffeners trimmed back to provide adequate clearance to panel;judged to be acceptable.

8. Are overhead equipment, distribution systems, ceiling tiles and lighting, and masonry block walls not likely to collapse onto the equipment?

Yes 9. Do attached lines have adequate flexibility to avoid damage?10. Based on the above seismic interaction evaluations, is equipment free of potentially adverse seismic interaction effects?Yes Yes Other Adverse Conditions

11. Have you looked for and found no adverse seismic conditions that could Yes adversely affect the safety functions of the equipment?

All panel doors were opened. No adverse conditions were observed.Door on adjacent cabinet 902-4 7 is slightly askew at bottom. However, door is adequately latched and judged to be acceptable.

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

Viewed 4 anchors (front clips) of 14 total. Remaining anchors could not be viewed due to cabling and limitations on access. Anchors viewed matched documentation, therefore it is reasonable to conclude that the anchors match plant documentation without further verification.

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

2. Does anchorage of equipment in the area appear to be free of significant Yes degraded conditions?
3. Based on a visual inspection from the floor, do the cable/conduit raceways and Yes HVAC ducting appear to be free of potentially adverse seismic conditions (e.g., condition of supports is adequate and fill conditions of cable trays appear to be inside acceptable limits)?4. Does it appear that the area is free of potentially adverse seismic spatial Yes interactions with other equipment in the area (e.g., ceiling tiles and lighting)?

Overhead light fixtures judged to be acceptable.

Swinging fixtures would only strike robust targets.Masonry wall near Switchgear 29 is well-restrained and judged to be acceptable.

5. Does it appear that the area is free of potentially adverse seismic interactions Yes that could cause flooding or spray in the area?Threaded fire piping well-supported and judged to be acceptable.
6. Does it appear that the area is free of potentially adverse seismic interactions Yes that could cause a fire in the area?7. Does it appear that the area is free of potentially adverse seismic interactions Yes associated with housekeeping practices, storage of portable equipment, and temporary installations (e.g., scaffolding, lead shielding)?
