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.)

The control room ceiling diffuser configuration is shown on drawings 1E-O-3754A, Rev. A and 1E-0-3712, Rev. AA. The ceiling diffusers (egg-crates) are not individually fastened to the tee track supporting structure.

However, as shown in LaSalle Calculation Nos. 777 and 8126-02E0, the ceiling support system is laterally restrained at the control room walls and at the control panel valences, the ceiling support system horizontal displacement is less than 3/8" during a seismic event, and the ceiling support system for the diffusers remains structurally adequate during a seismic event. Therefore, the diffusers' falling through the ceiling support system during a seismic event is judged to be not credible.Overhead light fixtures judged to be acceptable.
