Not Applicable

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

Existing foam and sea/ant in bottom of panel prohibit observation of welds between base channel and embedded floor steel. Bolts between panel base and base channel were observed to be acceptable.

Yes Because the control panel anchorage is shown on safety-related drawings IE-C-382 12Q0108.50-R-002 Rev. 1 Correspondence No.: RS-12-163 Sheet 2 of 3 Status: F N U Seismic Walkdown Checklist (SWC)Equipment ID No.: 2H13-P601 Equipment Class: (20) Instrumentation and Control Panels and Cabinets Equipment

ASSY -PANEL, EMERG CORE COOL SYST 2-3465, Rev. Y and IE-1-3466, Rev. F, and the control room maintains a constant climate not subject to excessive moisture, there is no reason to suspect that any of the anchorage welds are missing, damaged, or corroded.Therefore, the anchorage welds can be considered adequate.Interaction Effects 7. Are soft targets free from impact by nearby equipment or structures?

Yes 8. Are overhead equipment, distribution systems, ceiling tiles and lighting, and masonry block walls not likely to collapse onto the equipment?

The control room ceiling diffuser configuration is shown on drawings IE-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.

9. Do attached lines have adequate flexibility to avoid damage?Yes Yes Yes 10. Based on the above seismic interaction evaluations, is equipment free of potentially adverse seismic interaction effects?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?
