Location (Bldg, Elev, Room/Area): Area : AUX, -15, CAL-AB-101 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 Yes adverse seismic conditions (if visible without necessarily opening cabinets)?

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

Observed that LPSI 21 is missing an anchorbolt. This condition has been evaluated by calculation CA02066.

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)?

Cable trays are supported on walls and trapeze hangers,judged not to have any seismic concerns.

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?

The overhead threaded fire piping is judged to be well supported and not a concern for spray or flooding.

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)?

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

Observed panels mounted to masonry block wall. Masonry block walls, identified as T, S, N, AA and BB on drawing A-260, are safety-relatedand thus seismically ratedper IE Bulletin 80-11.

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)?

There are open ladder type cable trays, supportedon eitherunistrut frames or a combination of unistrut and rod hangerframes or cantileverbracket off unistrutframes. Typically the cable tray is clipped to every 2nd or 3rd cantileversupport bracket.

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)?

Verify whether cabinets 2D02 and 2D14 are bolted together. Conduit from 2D12 is a 1/8"to 2Y10-80 & 2D02 75-2208. 1/2"gap to 2YOIA and 1/4"gap to 2Y1 1 to Block wall.

Evaluated using 8 Hz frequency for cabinets 2% Damping Ratio, 1.5 PF Response Spectrum ABO27D2N.dat A=0.25g D= 2 * (1.5*0.25*386) / (8x2x3.14)A2 = 0. 11" < 1/4" OK

MCC 2N130 (PRESS HTRS) is 1/2" from a block wall.

Evaluated using 8 Hz frequency for cabinets 2% Damping Ratio, 1.5 PF Response Spectrum ABO27D2N.dat A=0.25g D= (1.5*0.25*386) / (8x2x3.14)A2 = 0.06" < 1/2" OK 480V Disconnect SW cabinet (2NB 104, 116 and 121) is in contact with fire piping. The Fire piping is 3-1/2" outside diameterand spans at 11' between supports and cabinet is approx. centered. The cabinet dimensions are 20" x 60" x 90" high.

Evaluation:

Assume each cabinet weight is equivalent to an MCC.

Per GIP Rev. 2A, Table C. 1-1, 800 lbs/cabinet, Total Weight = 1600 lbs Cabinetfrequency is estimated at 8 Hz, Response Spectrum AB027D2N.dat, Sa.cabinet = 0.25 g A-37

Max. Moment = 1149 Lbs*ft, Max. Stress = 8.00 ksi Considerthe use of black pipe which is typical A-53. A-53 pipe has an allowable stress of 16 ksi at ambient, therefore the fire pipe will not be affect by the cabinet.Not a seismic concern There is a tool hanging on RCP 22A P01 (Trip sensitive Equipment) may be banging on cabinet during a seismic event, this is a potentialproblem.

The equipment that is stored in the storagearea will roll into each other, but not into cabinet RCP 22AP01, therefore not a concern. However it is recommended that better tie offs to provided.

Masonry block walls, identified as D, E, F, G, H, Q, S, Y, Z and AA on drawing A-259, are safety-relatedand thus seismically rated per IE Bulletin 80-11.

Observed trash and recycling bins, but bins are light weight therefore they are not a seismic concern.

A conference room with chairsis bound by a cabinet that does not actuate equipment, therefore it is not a seismic concern.

Location (Bldg, Elev, Room/Area): Area : AUX, 45, CAL-AB-408 There is a cart with wheels locked, good seismic practice.

There are portablefilters that are not restrained,however the filters are far enough from equipment, therefore not a seismic concern.

There is scaffold part stagingbehind valve 2MS-3938-CV. The staging consist of racks those seismic adequacy is questionable. The racks may move and strike a drain line and MSS valves enclosure, therefore a potentialseismic concern. CR-2012-009724
