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)?
Yes
- 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?
Heat exchanger mounted to gallery steel.
- 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.)
Anchorage shown on drawings S-819A, Rev. G and S-899A, Rev. F.
- 6.
Based on the above anchorage evaluations, is the anchorage free of potentially adverse seismic conditions?
Not Applicable Yes Yes Interaction Effects
- 7.
Are soft tarcqets free from impact by nearby equipment or structures?
Yes C-220

- 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 walls are safety-related per drawing. A-227, Rev. V.
- 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 Other Adverse Conditions
