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)?

No 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?Yes 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.)

Not Applicable

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

IR 1397864: During the Seismic Walkdowns it was identified that one of the two latches on MCC 29-1 was not secured. The other latch is secured. The concern with unlatched door panels is that during a seismic event the door could open. If the door were to open, the doors could bang against the MCC and the impact could cause components within to change states. The other issue with open doors is that when the door is open the stiffness of the panel is reduced.Because this MCC is not a tall MCC, as long as one of the latches is functional, the seismic acceptability of the MCC is not compromised.

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.Anchora-qe

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

No 2. Is the anchorage free of bent, broken, missing or loose hardware?Not Applicable

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.)

Not Applicable Not Applicable Not Applicable

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

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

Yes Yes 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?Yes 10. Based on the above seismic interaction evaluations, is equipment free of potentially adverse seismic interaction effects?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?

Associated solenoid valve touches solid pipe insulation (typical for 2-8801A, B, and C valves). Valves fail closed upon loss of air per System Engineering.

Judged to be acceptable.

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

Viewed 6 anchors of 9 total. Remaining anchors could not be viewed due to cabling and limitations on access. Anchors viewed matched documentation, therefore it is reasonable to conclude that the anchors match plant documentation without further verification.
