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?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?

Yes C-326 Dresden Generating Station Unit 3 12Q0108.30-R-002, Rev. 2 Correspondence No.: RS-12-167 Sheet 2 of 7 Status: FI- N U Seismic Walkdown Checklist (SWC)Equipment ID No.: D03-2301-0003-V20 Equipment Class: (8) Motor-Operated and Solenoid-Operated Valves EauiDment DescriDtion:

HPCI/ Turbine Steam Line Valve Interaction Effects 7. Are soft targets free from impact by nearby equipment or structures?

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

Overhead light fixture with an open S-hook. Fixture has hard-wired cord and will not impact soft targets. Judged to be acceptable.

See IR 1396017.9. 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?Yes Yes 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?
