Seismic block walls, overhead lights have closed S-hooks and bulb guards.Subsequent to initial walkdown, NRC identified open S-hooks in this room. IR 1395981 was written. Unlikely that lights would fall on equipment since the S-hooks are not completely open and not all S-hooks for a light are open.9. Do attached lines have adequate flexibility to avoid damage?10.

Drawing M-1214 Sheet 3 Revision Z 4 of 12 anchor bolts have hairline cracks in the 1'thick foundation pad that do not extend into the base slab. A review of the design drawings was performed.
The tank locations are shown on Drawing M- 1216 Sheet 1 Revision W The anchor bolt locations and details are shown on Drawing M-1214 Sheet 3 Revision Z. The anchor bolts are embedded 1 '-3 Y2" in the base slab. The approximate total length of the anchor bolts is 3-9". The pad is shown on section G-G shows a #6 reinforcing bar outside of the anchor bolt that will provide confinement to the anchor.C-1 71 12QO108.10-R-001 Rev. 0 Correspondence No.: RS-12-159 Sheet 2 of 8 Status: M N U Seismic Walkdown Checklist (SWC)Equipment ID No.: 1DO01TB Equipment Class: (21) Tanks and Heat Exchangers Equipment

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% No of SWEL items requiring such verification)?
- 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?
