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% No of SWEL items requiring such verification)?
- 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
- 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: Not Applicable 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 Yes potentially adverse seismic conditions?

Description:
480 VAC Interaction Effects
- 7. Are soft targets free from impact by nearby equipment or structures? Yes Observed 1-7/8" clearancefrom back of MCC (drip shield) to concrete wall.
There is concern that the MCC could close the gap in SSE event and cause equipment to malfunction. Verification needed to ensure gap is sufficient given MCC flexibility (gap oriented in weak direction) and high elevation of the Aux Building (2047.5).
Licensing Basis Evaluation: Using a conservative lower bound frequency estimate of 5 Hz, a modal shape factor of 1.6 for cantilever action, and taking the peak spectral accelerationof approx. ig at the 2047.5 ft. elevation for 3%
damping (conservative), the upper-bound displacement is 6.3 in (= 1.6*386.4 in/sA2
- Ig / (2*pi*5 Hz)A2). Therefore, a 1-7/8" gap is acceptable.
- 8. Are overhead equipment, distribution systems, ceiling tiles and lighting, and Yes masonry block walls not likely to collapse onto the equipment?
- 9. Do attached lines have adequate flexibility to avoid damage? Yes
- 10. Based on the above seismic interaction evaluations, is equipment free of Yes potentially adverse seismic interaction effects?
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?
Cabinet internals could not be accessed during at-power walkdowns.
Internals will be inspected during next bus outage.
Internals accessed 2/24/13. No hazard.

- 10. Based on the above seismic interaction evaluations, is equipment free of Yes potentially adverse seismic interaction effects?
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?
Panelbolt not installed (1 out of 4) directly beneath relay K100.
No sensitive equipment affected, and therefore no adverse seismic concern.
WCNOC notified by SWT.

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% Yes of SWEL items requiring such verification)?
- 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
- 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: Yes This question only applies if the item is one of the 50% for which an anchorage configuration verification is required.)
Drawingcalls for 4 no. 5/8" plug welds. Verified per E-020-0007.
- 6. Based on the above anchorage evaluations, is the anchorage free of Yes potentially adverse seismic conditions?
