Comments SEWS Notes on Anchorage:

Anchorage:

Panel is 10.5' wide (long) on inside (rear side) and front side. Anchored by 4 tabs in front and 4 on back. All anchored by welded friction clips (clips are welded to panel base channels).

Clips are bolted by a 3/4" concrete expansion anchors. Clips are 3/8" thick, 2" wide and about 5" long.Seismic Walkdown Team: D. Carter & J.

LPCI/ LPCI Iniection Line Valve 8. Are overhead equipment, distribution systems, ceiling tiles and lighting, and masonry block walls not likely to collapse onto the equipment?

Light fixtures mounted with beam clamps oriented incorrectly (friction resisting dead load). Light fixture would not negatively affect valve below and is unable to sway far enough to hit East Bank CRD. Fixture is judged to be acceptable.

IR 1390318: Light fixture above 2-1501-21A valve supported by chain connected to a cantilevered channel via a beam clamp. The beam clamp appears to rely solely on the slip capacity of the beam clamp bolt to resist the dead load of the light fixture, which could be inadequate in a seismic event. Recommend replace the beam clamps connecting the light fixture chains to the unistrut supports with the appropriate spring-loaded nut and bolt assembly.

Not an immediate seismic concem. Identified during area walk-by inspection.

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 findinas.

Additional soace is provided at the end of this checklist for documentina 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?3. Is the anchorage free of corrosion that is more than mild surface oxidation?

Yes Yes Yes 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

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

Cabinet is anchored with four angle clips. Each clip has one 5/8-inch wedge anchor, Yes C-221 12Q0108.30-R-0O1, Rev. 1 Correspondence No.: RS-12-167 Sheet 2 of 3 Status: Y N U Seismic Walkdown Checklist (SWC)Equipment ID No.: D02-2252-0010 Equipment Class: (20) Instrumentation and Control Panels and Cabinets Eauioment Descriotion:

CONTROL PANEL DG Meterina and Relay Cabinet Interaction Effects 7. Are soft targets free from impact by nearby equipment or structures?

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