Additional soace is provided at the end of this checklist for documentinq other comments.Anchorage 1. Is anchorage configuration verification required (i.e., is the item one of the 50%of SWEL items requiring such verification)?

No 2. Is the anchorage free of bent, broken, missing or loose hardware?Yes 3. Is the anchorage free of corrosion that is more than mild surface oxidation?

Yes Minor corrosion of plug welds judged to be acceptable.

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.)

Not Applicable

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

Viewed anchorage in 10 of 11 switchgear cubicles.

Remaining anchorage in 1 th cubicle could not be viewed due to Operations concerns.

Anchorage viewed in the 10 cubicles was judged to be acceptable; therefore, it is reasonable to conclude that the anchorage in the 11 th cubicle would also be acceptable.

4160V SWGR 142X Interaction Effects 7. Are soft targets free from impact by nearby equipment or structures?

Overhead light fixture near bus duct at back side of switchgear.

Bus duct is robust; therefore, seismic interaction due to pendulum motion of light during a seismic event is not a concem.8. Are overhead equipment, distribution systems, ceiling tiles and lighting, and masonry block walls not likely to collapse onto the equipment?

Overhead light fixtures judged to be acceptable.

Adjacent masonry wall to the east of the switchgear is safety-related per drawing A- 186, Rev. AR.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 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?

10 of 11 switchgear cubicles were opened. 11 th cubicle could not be opened due to Operations concems. No adverse seismic conditions were observed in the 10 opened cubicles.Comments Seismic Walkdown Team: J. Griffith & M.

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

Stitch weld on front and rear of cabinets judged to be acceptable.

2. Is the anchorage free of bent, broken, missing or loose hardware?No Yes 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.)

Not Applicable

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

Yes C-29 12Q0108.50-R-001 Rev. 1 Correspondence No.: RS-12-163 Sheet 2 of 6 Status: l N U Seismic Walkdown Checklist (SWC)Equipment ID No.: 1AP15E Equipment Class: (2) Low Voltage Switchgear EauiDment DescriDtion:

480V SWGR 133 Interaction Effects 7. Are soft targets free from impact by nearby equipment or structures?

Switchgear and transformer are connected at the top via tack weld and bolted angle. The switchgear and transformer are also stiff in their long dimensions, therefore interaction of the two items between the top connections and base during a seismic event is judged not to be credible.8. Are overhead equipment, distribution systems, ceiling tiles and lighting, and masonry block walls not likely to collapse onto the equipment?

Overhead light fixture rigidly mounted and judged to be acceptable Masonry wall adequately restrained; is also short, L-shaped, and with a running bond. Judged to be acceptable.

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