7. Are soft targets free from impact by nearby equipment or structures? Yes Overheadlight may strike sight glasses.

10/3/12 - Overhead lights were deemed not a credible seismic concern due to their lightweight and to typical constructionpractices. Also, they have been previously evaluated by CCNPPand found seismically acceptable.

8. Are overhead equipment, distribution systems, ceiling tiles and lighting, and Yes masonry block walls not likely to collapse onto the equipment?
9. Do attached lines have adequate flexibility to avoid damage? Yes Tubing to the valve and instrumentationhas adequate flexibility, therefore judged not to be a seismic concern.
10. Based on the above seismic interaction evaluations, is equipment free of Yes 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?
