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% Yes of SWEL items requiring such verification)?

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 Minor grout pad cracking near bolts judged to be acceptable because bolts are cast in place into the concrete slab.5. Is the anchorage configuration consistent with plant documentation? (Note: Yes This question only applies if the item is one of the 50% for which an anchorage configuration verification is required.)

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

IR 1396014: LIGHT FIXTURE CONNECTION DEFICIENCY During the Seismic Walkdowns it was identified that a light fixture just west of the 3A Hx in the SE LPCI Comer Room had a detached chain on one side of the fixture. However, the other chain at the same end of the fixture was securely attached and the two chains at the other end of the fixture were also securely attached.

Therefore, the fixture is judged to be acceptable.

9. Do attached lines have adequate flexibility to avoid damage?Yes Yes Yes 10. Based on the above seismic interaction evaluations, is equipment free of potentially adverse seismic interaction effects?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?
