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?

Minor shrinkage cracks in wall and ceiling judged to be acceptable.

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.)

Yes Yes

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

Yes C-468

Description:

COOLER, CUBICLE - 2A CS PMP RM COOLER Interaction Effects

7.

Are soft targets free from impact by nearby equipment or structures?

Tube in contact with cooler brace. Tube is flexible, brace is rigid; judged to be acceptable.

8.

Are overhead equipment, distribution systems, ceiling tiles and lighting, and masonry block walls not likely to collapse onto the equipment?

9.

Do attached lines have adequate flexibility to avoid damage?

Cooler is restrained to wall; thus, there are no concerns regarding the relative flexibility of the cooler and attached piping.

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?

Comments SEWS Anchorage Notes:

Cooler supported by four 5/8" rods. Each rod is anchored by four 1/2" concrete expansion anchors.
