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.Y N U N/A 1. Does anchorage of equipment in the area appear to be free of X potentially adverse seismic conditions (if visible without necessarily opening cabinets)?

Y N U N/A 2. Does anchorage of equipment in the area appear to be free of significant X degraded conditions?

Y N U N/A 3. Based on a visual inspection from the floor, do the cable/conduit X 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 4. Does it appear that the area is free of potentially adverse seismic spatial x interactions with other equipment in the area (e.g., ceiling tiles and lighting)?

Block walls SB 1-7 and SB 1-8 are adequate based on Calculations DSC-0086 and DSC-0087, respectively.

Block wall SB 1-10 is adequate based on calculation DSC-0089_

1.These calculations are part of aJollow-up seismic analysis in support ofiE80-1 I calculations.

All block walls in area are adequate.Related equipment on SWEL for this area: BAT- 1-2 DOD Paul C. Rizzo Associates, Inc.E'GINEERIS

There is a small gap between one of the nut's and base on the east support post for the tank. Gap is not considered significant.

One anchor bolt is not fully engaged by half a thread on the north post of the tank. This minor thread engagement issue is judged not significant.

Two valves with reach rods through the wall are on the supply piping to pump CH-P-1C. The gap at the wall penetration around each rod is approximately 1 ". The supply piping does not have lateral support and its potential movement in a seismic event could close the gap at reach rod wall penetration and cause binding. Judged acceptable, as the pipe goes through a ceiling penetration, which would provide some restraint, as well as the fact that the valves are manual valves with reach rods and that potential reach rod binding would be acceptable.

Does anchorage of equipment in the area appear to be free of X potentially adverse seismic conditions (if visible without necessarily opening cabinets)?

Y N U N/A 2. Does anchorage of equipment in the area appear to be free of significant X degraded conditions?

Y N U N/A 3. Based on a visual inspection from the floor, do the cable/conduit X 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 4. Does it appear that the area is free of potentially adverse seismic spatial X interactions with other equipment in the area (e.g., ceiling tiles and lighting)?

Control room ceiling main runners are supportedfrom concrete ceiling by wires at-4' spacing. Each ceiling tile (i.e., egg grating) is tied to the main runners at each of its four corners and judged not to be a potential falling hazard. Block walls SB3-1, SB3-5, SB3-8, and SB3-9 are adequate based on calculations DSC-0095_1, DSC-0097, DSC-0 103, and DSC-O103, respectively.

These calculations are part of a follow-up seismic analysis in support of IE80-11 calculations.

INV-VITBUS I panel has a gap of 1" to a wall. It is judged that this gap is adequate and there will be no impact to the wall. HVAC grill over INV-Vitbusl-3 is held with small screws, but appears to be rugged, it is not a credible fall hazard. Block wall SB I-11 and SB 1-12 are adequate under calculation DSC-0090 and DSC-0091, respectively.
