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 findinqs. 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)?

SQUG 1-SIS

2.

Is the anchorage free of bent, broken, missing or loose hardware?

Yes 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?

Panel welded to embedded plate through thick shim plates

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.)

SQUG SEW package for 1-SIS was incomplete and did not contain the detailed information or sketches of the anchorage configuration. AR 2012-13310, Panel 1-SIS anchorage documentation could not be located was generated as a result

6.

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

Not Applicable No No Interaction Effects C-346
