WALKDOWN CHECKLIST FORM Sheet 2 of 5 Status: YE NFIl U[]Seismic Walkdown Checklist (SWC) SWELl- 083 Equipment ID No. X55 Equip. Class Transformers (04)Equipment Description Transformer to Y3/Y31 5. Is the anchorage configuration consistent with plant documentation?

Yr] NE-] U-] N/AE (Note: This question only applies if the item is one of the 50% for which an anchorage configuration verification is required.)

Note: The transformer and its anchorage are different from what is shown in drawing E15A-8, Rev. EO. This is due to the replacement of the transformer per EC 0000016677, Rev. 0.6. Based on the above anchorage evaluations, is the anchorage free of YE NEl UL-potentially adverse seismic conditions?

Interaction Effects 7. Are soft targets free from impact by nearby equipment or structures?

The Unistrut supporting conduits X1200 and A 3025 above X55 has two anchors with nuts that are not fully engaged. The engagement is greater than 75% in both cases, and this is judged to be adequate to develop the full strength of the anchor. Therefore, this is not considered a potential seismic interaction.

See attached photo.8. Are overhead equipment, distribution systems, ceiling tiles and lighting, and masonry block walls not likely to collapse onto the equipment?

Masonry wall 194.20 is seismically qualified.

YZ NEI UE] N/AE7 (Note: This question only applies if the item is one of the 50% for which an anchorage configuration verification is required.)

The anchor configuration matches drawings E15A3 E2, E15A-8 EO, E15A-7 and the SEWs package, detail 3/3. Two additional bolts were noted for the connection of the panel to the channel. The design in calculation C15.0.3059 specifies 3/16" fillet welds, which also exists at the connection, therefore, the bolts are extra and the configuration is acceptable.

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

Interaction Effects 7. Are soft targets free from impact by nearby equipment or structures?

Unistrut supporting conduit was noted to be within an inch of the top of the cabinet. This is acceptable based on minimal vertical displacement of the cabinet during a seismic event. Panel is also touching the column! wall on the right side. This is acceptable, as the cabinet does not contain essential relays and is therefore not prone to chatter.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?10. Based on the above seismic interaction evaluations, is equipment free of potentially adverse seismic interaction effects?YN NE]I UM N/AE]YE NE] U[-E N/AE--YN NEI UE- N/AE]YM NEI UE]

YZ ND] ULi N/ADl (Note: This question only applies if the item is one of the 50% for which an anchorage configuration verification is required.)

Interaction Effects 7. Are soft targets free from impact by nearby equipment or structures?

Panel D-7 is mounted above EPA I with its cover latch facing the floor, and was examined for an interaction involving the cover coming unlatched over EPA 1 during a seismic event. The cover appears to be adequately latched and the panel securely anchored, and does not present a seismic interaction concern. See attached photo.8. Are overhead equipment, distribution systems, ceiling tiles and lighting, and masonry block walls not likely to collapse onto the equipment?

Masonry wall 194.20 is seismically qualified.

See Drawing C-961 SHI, Rev. El.9. Do attached lines have adequate flexibility to avoid damage?There is a short, rigid conduit running between EPA 1 and EPA2, as well as a conduit running from EPA I that is in close proximity to EPA2.Both panels and the conduit are all anchored to the same wall, so this is not judged to be a seismic interaction hazard.

Bolt is in place, nut is 75%engaged.

There are no wires in the conduit, therefore conduit is secure and acceptable with one bolt.-Panel A-10 has only one screw holding the cover on, but is acceptable (see photo below)-CR-PNP-2013-1201 initiated for rod hanger for 1" copper demin. line detached at clamp at top of rod, above! north of 19-HO- 166. The next support is approximately 3' downstream, 7' upstream.
