Area Walk-By Checklist (AWC) AWC-001

Location: Bldg. RAB Floor El. -35 Room, Area1 Safeguards B Room

SWEL Components: SWEL1-012, 036

Instructions for Completing Checklist This checklist may be used to document the results of the Area Walk-By near one or more SWEL items. 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 adverse seismic conditions (if visible without necessarily opening cabinets)?

• Anchor bolt on SISR-883 missing (1 of 4). See LB-01 in Attachment F.

Y N U N/A

2. Does anchorage of equipment in the area appear to be free of significant degraded conditions?

• All anchorage is free of significantly degraded conditions.

Y N U N/A

3. Based on a visual inspection from the floor, do the cable/conduit raceways and 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)?

Y N U N/A

1 If the room in which the SWEL item is located is very large (e.g., Turbine Hall), the area selected should be described. This selected area should be based on judgment, e.g., on the order of about 35 feet from the SWEL item.

4. Does it appear that the area is free of potentially adverse seismic spatial interactions with other equipment in the area (e.g., ceiling tiles and lighting)?

Y N U N/A

5. Does it appear that the area is free of potentially adverse seismic interactions that could cause flooding or spray in the area?

Y N U N/A

6. Does it appear that the area is free of potentially adverse seismic interactions that could cause a fire in the area?

Y N U N/A

7. Does it appear that the area is free of potentially adverse seismic interactions associated with housekeeping practices, storage of portable equipment, and temporary installations (e.g., scaffolding, lead shielding)?

Y N U N/A

• Lighting is in walkways, posing no seismic concern. • A temporary housing has been installed in the Switchgear B

Room. It has the potential to impact panels near it. The walls are bolted together, but there are no anchors bolting the enclosure to the floor. There is only a 7” clearance from LCP-62 and one side of the enclosure.

o This was resolved using CR-12-5172 and EC40448. See photos. Enclosure was braced at the top and bottom to structural steel members to ensure rigidity of the enclosure.

o The trash cans were also determined to be made of material that could not damage the surrounding cabinets.
