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 ofjudgments andfindings. Additional space is provided at the end of this checklist for documenting other comments.

Anchorage1. Is the anchorage configuration verification required (i.e., is the item one of the 50Yo of SWEL items requiring such verification)?

The equipment is in a line with other cabinets D2P and YRF2. The internal connectionof these panels was verified. Eqch of these panels are anchored to the concrete floor withfour l" diameter anchor bolts.

2. Is the anchorage free of bent, broken, missing or loose hardware?3. Is the anchorage free of corrosion that is more than mild surface oxidation?

N o significant c orrosion identifeid

4. Is the anchorage free of visible cracks in the concrete near the anchors?5. Is the anchorage configuration consistent with plant documentation?(Note: This question only applies if the item is one of the 50o/o for which an anchorage configuration verification is required.)

The seismic qualification of the line-up that consists of YRF2, D2P and YV2 is in SOUG calculation C-CSS-D2P.SQUG calculation C-CSS-YV2 indicates FCR 86-0272 implemented to resolte a pounding concern.

No gap observed between cabinets, confirming I.'CR 86-0272.6. Based on the above anchorage evaluations, is the anchorage free of potentially adverse seismic conditions?
