Does anchorage of equipment in the area appear to be free of potentially Yes adverse seismic conditions (if visible without necessarily opening cabinets)?

Existing foam and sealant in bottom of control room panels prohibit observation of welds between base channel and embedded floor steel. Bolts between panel base and base channel were observed to be acceptable.

2. Does anchorage of equipment in the area appear to be free of significant Yes degraded conditions?
3. Based on a visual inspection from the floor, do the cable/conduit raceways and Yes HVAC ducting appear to be free of potentially adverse seismic conditions (e.g., condition of supports is adequate and fill conditions of cable trays appear to be inside acceptable limits)?Conduits in contact with tray supports and other conduits.

Judged to be acceptable due to flexibility of items.4. Does it appear that the area is free of potentially adverse seismic spatial Yes interactions with other equipment in the area (e.g., ceiling tiles and lighting)?

The control room ceiling diffuser configuration is shown on drawings 1E-O-3754A, Rev. A and IE-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.

Does it appear that the area is free of potentially adverse seismic interactions Yes that could cause a fire in the area?D-178 12Q0108.50-R-002 Rev. 1 Correspondence No.: RS-12-163 Sheet 2 of 8 Status: F-1 N U Area Walk-By Checklist (AWC)Location (Bldg, Elev, Room/Area):

Have you looked for and found no other seismic conditions that could Yes adversely affect the safety functions of the equipment in the area?Phone mounted on rear control boards. Receiver in cradle not expected to"leap" out during seismic event and therefore judged to be acceptable.
