The space below each of the following questions may be used to record the results of judgments and findings.Additional space is provided at the end of this checklist for documenting other comments.1. Does anchorage of equipment in the area appear to be free of potentially Yes adverse seismic conditions (if visible without necessarily opening cabinets)?

Missing nut on tank 2-TK-256 -Later determined this was an abandoned anchor bolt and no nut is necessary.

NRC Inspector identified loose JUNCTION boxes 2-NL1-151 and 2-NPS-153

-conduit supported

-OK per SQUG 2-NLI-151.

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)?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)?
5. Does it appear that the area is free of potentially adverse seismic interactions Yes that could cause flooding or spray in the area?6. Does it appear that the area is free of potentially adverse seismic interactions Yes that could cause a fire in the area?7. Does it appear that the area is free of potentially adverse seismic interactions Yes associated with housekeeping practices, storage of portable equipment, and temporary installations (e.g., scaffolding, lead shielding)?
