1: Does anchorage of equipment in the area appear to be free of YZ NIh UI- N/AE]

potentially adverse seismic conditions (if visible without necessarily opening cabinets)?

A knee-bracefor conduit supportnear Valve 2E41-F007 near the 2T41-BOOSB HPCIcooler has only one anchor bolt (CR 515489).

There is a hole in the base platefor the second bolt, but it appearsthat only one bolt wasever installedsince there is no hole in the concrete.

The knee-brace is one of apair of supportsfor a small.conduitnear the wall. The second knee brace is fairly large and.has all anchorbolts; so.

it is judged to have sufficient capacity to support the small conduit during a seismic event. This issue is addressedin CR 515489.

A "Hot Pipe" sign was found lying on the gratingon the 96' elevation of the Unit 2 HPCIRoom (on the Unit 2 HPCIRoom-CoolerPlatform) next to: the 2T41-BOOSA cooler but not attachedto anything.

The tag is light and not located near any sensitive equipment, so it isjudged that there is no potentially adverse seismic condition due to this loose tag (CR 519707).

The H01 test connection lead was found lying on top ofthe 2T41-BOO5A cooler. The lead is very light and is attachedby the connection cable to the body of the cooler. There is no delicate equipment in the vicinity of the lead, and the cooler is very rugged, so any impact will not be significant. Therefore, it is judged to not be apotentially adverse seismic condition. This item does not need to be moved Evaluated by: John McFarland. Date: 09/11/2012 Jeff Horton 09/1112012 Page 30 of 186

Location: Bldg. REACTOR Floor El. 87 Room, Area 1 NE Diagonal 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 resuIts 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 YI NEI UI' N/AD]

potentially adverse seismic conditions (if visible without necessarily opening cabinets)?

2. Does anchorage of equipment in.the area appear to be free of significant YfI NEI Ui] N/A[F]

degraded conditions?

3. Based on a visual inspection from the floor,, do the cable/conduit YN NE] UE] N/Al1 raceways and HVAC ducting appear to be free of potentially adverse seismic conditions (e.g., condition of supports is adequateand fill conditions of cable trays, appear to be inside acceptable limits)?

There was a 1 "diameter demineralizedwaterpipe discovered that appearedto be missing a U-bolt (CR 523085). There is an angle with.

two holes drilled in it immediately adjacent to the pipe above the 2H21-POOl instrument rack that looks like it was intended as a pipe support.

The pipe has additionalsupports on either side of the missing support and is light, so it isjudged that the existing supports have adequate capacity to support the pipe. Therefore, there is no potentially adverse seismic condition. However, the missing support needs to be reinstalled.

4. Does it appear that the area is free of potentially adverse seismic spatial YM NEI U-- N/Al]

'interactions with other equipment in the area (e.g., ceiling tiles and lighting)?

There is a temporarypower cord strung along the building steel to the 2E11-COO2A RHR Pump. The bulk of the power cord is tied into a loop near a steel beam, which isjudged sufficient to prevent impact between.

the cable andany sensitive equipment on the other side of the beam.

Therefore, there is no potentially adverse seismic interaction.

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.

6. Does it appear that the area is free of potentially adverse seismic Y0 N[:] UE N/AD interactions that could cause a fire in the area?
7. Does it appear that the area is.free of potentially adverse seismic YZ NEI UEZ N/AZ interactions associated with housekeeping practices, storage of portable equipment, and temporary installations (e.g., scaffolding, lead shielding)?

There was a 6' metal ladder left unrestrainedbehind the 2H21-P018 RHR Instrument Rack (CR 522935). The ladder wasplaced behind the diagonalsupportfor the rack anda steel column, such that during a seismic event, the ladder would not be able to impact anything except supportsteel. The impact isjudged by the SWEs to be credible but not significant. Therefore, there is no potentiallyadverse seismic condition.

There are afew items (aplastic bag, a roll of caution tape and a small metalpiece) left loose in the contaminatedareaaroundthe 2E11-C002C RHR Pump. All of the items are small andlight and located awayfrom sensitive equipment, so arejudged to not create a potentially adverse seismic:condition.

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

Comments (Additional pages may be added as necessary)

There was a 3' long bent steel support that was sittingon thefloor next to the 2H21-PO01 instrument rack (CR 523087). The support is small and light, and is not located near any sensitive equipment, so it isjudged that there is no potentially adverse seismic condition. It was not readily apparentwhere the support belonged or whether itneeded to be reinstalled Evaluated by: John McFarland ý* Date: 09/24/2012 Jeff Horton 09/24/2012 Page 44 of 186

There is a U bolt support for a fire protection pipe (see photographs2 and 3) which is not securely fastened to the angle support. A nut is missing and anotheris not tightened. The pipe is supported Vertically butthe angle support and the U bolt in place to prevent the pipe from moving off the support laterally. Vertical seismic accelerationsare not greatenough for the bolt to be lifted out of place. It is judged to be seismically adequate. CR 523486 has been written to replace the missing/unsecurednuts.

There are two brass nozzles sitting loose on top of the Gas Cylinder Location 2P33-P066 andtwo brassnozzles sittingon the framefor panel 2H21-P405B, which is a~highpotentialto cause aplant transient (CR 515750). The nozzles are small andrelatively light, so they are unlikely to cause any structuraldamage duringa seismic event.

However, due to theirlocation on the supportfor a high trip hazard panel, there is a concern that the nozzles could potentially cause a plant transient.
