Area Walk-By Checklist (AWC) AWC-001_

Location: Bldg. RAB Floor El. -35 Room, Area' Safe-guards B Room SWEL Components: SWEA-012Fo. 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 YE- NO UEl N/A[D 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.
2. Does anchorage of equipment in the area appear to be free of YZ NE-] u[-] N/A--

significant degraded conditions?

0 All anchorage is free of significantly degraded conditions.

3. Based on a visual inspection from the floor, do the cable/conduit YN NE]I UE N/AE]

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)?

I 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.

2. Does anchorage of equipment in the area appear to be free of Y[I ND U- N/AD significant degraded conditions?
  • Slight surface corrosion on two base plates for pipe supports on LS-CC-701 1 BS; WR 288395 initiated to address corrosion
3. Based on a visual inspection from the floor, do the cable/conduit Y[K N' UD N/AD 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)?

I 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.
