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. | |||

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.

Need bulbs removed from overhead light fixture.IR 1389874: Damaged lighting and support above instrument rack 2202-19A, one fluorescent light bulb in the fixture is broken with only a piece left in the socket and the other bulb appears to be loose enough to fall. This fagl could potentially affect the vibration sensitive equipment below. Station removed loose and.-broken bulbs. In addition, the support members for the lighting fixture appear to be bent at the channel fitting connection.
Although bent, the supports were judged to not pose a seismic interaction concern.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?I 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?

Viewed 5 of 6 anchors. View of north side middle anchor obstructed by junction box attached to panel. Anchors viewed matched documentation.
Thus it is reasonable to conclude that the anchors match plant documentation without further verification.
