Anchoraie
- 1. Is the anchorage configuration verification required(i.e., is the item one ofthe 50% of SWEL items requiring such verification)?
YO-N
- 2. Is the anchorage free of bent,, broken, missing or loose hardware?
The component is welded to a wide flange beam, so there is no anchorage.
- 3. Is the anchorage free of corrosion that is more than mild surface oxidation?
There is mild surface oxidation on the two top welds. Since oxidation is only on the surface, the welds are not degraded. Therefore, judged not to be a concern.
- 4. Is the anchorage free of visible cracks in the concrete near the anchors?
The component is welded to a wide flange beam, so there is no concrete.
- 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.)

A nut is missing for the U bolt on the grounding bar for conduit MC5153 which,frames into top of panel. Contact is being made between. the conduit and grounding bar and the conduit. This is not a seismic concern.
Conduit at northeast comer of panel at top is not fastened to the grounding bar. This is not a seismic concern.
There is a cantilevered strut support which is unused (see photograph 3). It is very close to the. conduits coming out of panel, which could impact them during a seismic event.

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 and findings. Additional space is provided, at the end of this checklist for documenting other comments.
Anchorage
- 1. Is the anchorage configuration verification required (i.e.,. is the item one of the 50% of SWEL items requiring such verification)?
Panel opened per work order SNC426989.
- 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?
- 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 50% for which an anchorage configuration verification is required.)
Anchorage is consistent With calculation SNCH-99-406, Rev. 0.
- 6. Based on the above anchorage evaluations, is the anchorage free of potentially adverse seismic conditions?
The welds exhibited poor installation at the interior corner of the panel (see photograph 3). Calculation SCNH-99-406, Rev. 0 states a 2" and 2 1/2" long weld in this location. The actualflengths were longer than the lengths called out in the calculation. The additional capacity resulting from the longer length exceeds any potential reduction caused by poor installation. It is judged to be seismically adequate.

Originally identified as an A-46 and IPEEE outlier due to a ceiling light located directly over panel (see photograph 4) that was not properly wire tied to support at the ceiling. DCR 90-042 installed a wire tie for the light support. The walkdown verified that this wire tie was installed.
