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

The 7' tall Rack 5 is anchored at the top and bottom per drawing 9321-F-7003. There are conduits/tubing fixed on the concrete wall and going into the rack. During a seismic event the rack will move with the concrete wall preventing it from beating against the wall. Conduits entering Rack 5 are attached to the concrete wall which the rack is attached to so conduits and rack will move together during a seismic event.8. Are overhead equipment, distribution systems, ceiling tiles and lighting, and masonry block walls not likely to collapse onto the equipment?

The fluorescent light tubes need wires securing them to the fixture to prevent them from falling on the rack in a seismic event. Several fluorescent lights are out and need to be replaced.

CR IP2-2012-06483 has been issued to track resolution.

5. Is the anchorage configuration consistent with plant documentation?

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

Not applicable since component is in-line.6. Based on the above anchorage evaluations, is the anchorage free of Y[I NEI UW1 potentially adverse seismic conditions?

Yes, based on the above anchorage evaluations, the anchorage is free of potentially adverse seismic conditions.

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

Yes, soft targets are free from impact by nearby equipment or structures.

YN NWJ u-- N/A-'8. Are overhead equipment, distribution systems, ceiling tiles and lighting, YN NWI UW- N/AD-and masonry block walls not likely to collapse onto the equipment?

The masonry brick wall was seismic qualified by Computech Report no.R547.01. Therefore, overhead equipment, distribution systems, ceiling tiles and lighting, and masonry block walls are not likely to collapse onto the equipment.

9. Do attached lines have adequate flexibility to avoid damage? Y[ NWI U[-W N/AD-Yes, attached lines have adequate flexibility to avoid damage.10.

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

YN Ni1 Yes the anchorage configuration verification is required.2. Is the anchorage free of bent, broken, missing or loose hardware?Yes the anchorage is free of bent, broken, missing or loose hardware.3. Is the anchorage free of corrosion that is more than mild surface oxidation?

Minimal surface corrosion on anchors & tank side. Judged acceptable.

4. Is the anchorage free of visible cracks in the concrete near the anchors?YN NEI ULI] N/AD Y[ NEI U-I N/AD-Y[ NEI uD- N/AD-Coating is chipped on concrete pedestal and nearby floor. No noticable cracks of significance where observed.

Acceptable.

Y; NDi U[-I N/AZ1 (Note: This question only applies if the item is one of the 50% for which an anchorage configuration verification is required.)

Anchorage matches SQUG (SEWS).6. Based on the above anchorage evaluations, is the anchorage free of YN NEI Ur-1 potentially adverse seismic conditions?

Yes based on the above anchorage evaluations, the anchorage is free of potentially adverse seismic conditions.

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

Conduits and unistruts near by tank are close to touching tank. 1/8" to 1/2" gap on some of the nearby conduits.

All occurences are judged acceptable given robustness of conduits and the tank.8. Are overhead equipment, distribution systems, ceiling tiles and lighting, and masonry block walls not likely to collapse onto the equipment?

Yes overhead equipment, distribution systems, ceiling tiles and lighting, and masonry block walls are not likely to collapse onto the equipment.

9. Do attached lines have adequate flexibility to avoid damage?Yes 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?Yes based on the above seismic interaction evaluations, the equipment is free of potentially adverse seismic interaction effects.Y[ NEI UI- N/AD YN NEI U[- N/A--YZ NEI UD- N/ADl YZ NEI Uil EN-DC-168 REV 0 Engineering Report No. IP-RPT-12-00037, Rev. 0, Page C-397 of 434 ATTACHMENT 9.6 SEISMIC WALKDOWN CHECKLIST FORM Sheet 3 of 5 1P2 Status: Y[ NEI U[--Seismic Walkdown Checklist (SWC) SWELl-100 Equipment ID No. O022EDSAT Equip.

11. Have you looked for and found no other seismic conditions that could Y[ N[l ULi adversely affect the safety functions of the equipment?

Fire piping above uses threaded fittings that could leak and spray due to a seismic event. At time of walk down it was not known if the system was a dry or wet system.: If they leak water the tank would remain operable.Comments (Additional pages may be added as necessary)
