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.)

Drawing 20E-0-3391BK Revision D Anchor spacing is 10" at 2 locations while drawing specifies 12". NSWP-S-05 allows 2 diameter relocation which would equal 10" for 1" diameter expansion anchors therefore OK.

6.

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