Area IAB-la Floor El.

574 Bldg.

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 ofjudgments 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)?

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

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)?

Piping in the qreawas identffied to be rigidly supported.

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)?

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

TB Chillers 1P46-B00lA and IP46-B00lB are very large double stack chillers anchoredwith onlyfour 3/4" snchor bolts on a -l6" wide x -6" high pedestal. These chillers are not category I and anchorage may not be adequatefor seismic loading. Judged acceptable because the chillers have a limitedwater supply andwould not impact orflood any CAT-I components if they shouldfail.

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

Anchorage forTB chillers identified with significant coruosion. This is judged to be acceptable, as described in comments for Question I.

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)?

Corrosion on anchors identified in instrument racks base. Judged not to be a concern for operability or seismic issues.

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)?

HVAC ducts in the areawere identified to be rigidly supported.

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)?

Small nut securingfloor gratingfound not fully tightened. Judged not to be signfficant as 8 other fully tightened nuts are present at that interface. Related equipment on SWEL for this area: l82lN0067C 1821N0073C Sheet 100 of139 N/A N/A N/A X X X X

l. Does anchorage of equipment in the arca appeat to be free of potentially adverse seismic conditions (if visible without necessarily opening cabinets)?

In the concrete padfor Pump 0P54C0002, surface spallingwas observed. Additionally, 2 of the 4 -5/8" anchor bolts have an edge distance of -4 inches. These conditions are iudged OK, as the pump is rigidly supported at the base of the nozzle, which will provide additional restraint.

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

Corrosion observed in the base platefor 2H5l-P7538 judged OK becausefalling would not impoct any nearby components. Coruosion observed in ESIIl Chlorination Skid judged OK since it is top restrained and a very light skid.

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)?

Rigidly supported raceways identffied in the area, spanning -10 ft. Attached top entry conduit for H5 I -P}l0A observed to have friction-type clamps with no restraining clamps. Friction clamps judged OK due to very small imposed loads.

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)?

Fluorescent lightfixture is rigidly supported. Lights appear to be twist-in type but are out of the zone of inJluence and judged not likely to cause spatial interaction. Overhead bridge crane not a credible interaction source. Space heater judged OK due to lateral restraints andflexible lines. Related equipment on SWEL for this area: OHs lPl3l0 0P49D0001A 0P49F0502A 1P45C00018 1P45F01308 1P45F0660 1R24S0032 X X X X

No concerns identified regardingfire sources.

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.9., scaffolding, lead shielding)?

Very tall temporary scaffolding noted in area. Temporary unrestrained storage container observed adjacent to H5 I -P}l0A. Items judged OK due to temporary nature.

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

Potential Fire Sources in the Area: Flammable Storage Cabinets by IB-218 and IB-2l l. No concerns identified regardingfire sources.

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)?

Scaffold structure identified as being used as o support systemfor a Chiller Unit. Falling of the scaffold on the nearby MOV judged not a concern since it will not induce a significant damage to the valve or nearby pipe lines. However, a condition report (CR 2012-12373) was issued to address an unauthorized modffication to the plant for a chiller unit.

8. Have you looked for and found no other seismic conditions that could adversely affect the safety functions of the equipment in the area?

Chatter of the low ruggedness relays is acceptable because the functions of the relay contacts are not required durino the period of stronq motion and chatter will also not affect availability.
