There is a Unistrut pipe clamp on the west wall missing a bolt. The pipe clamp is spread open, offering no restraint to the supported pipe (CR 515734). There are intact pipe clamps above and below the open clamp, so the, unrestrained span of the conduit is small.

A knee-brace for conduit support near Valve 2E41-F007 near the 2T41-BOOSB HPCI cooler has only one anchor bolt (CR 515489).There is a hole in the base plate for the second bolt, but it appears that only one bolt wasever installed since there is no hole in the concrete.The knee-brace is one of a pair of supports for a small.conduit near the wall. The second knee brace is fairly large and .has all anchor bolts; so.it is judged to have sufficient capacity to support the small conduit during a seismic event. This issue is addressed in CR 515489.2. Does anchorage of equipment in the area appear to be free of significant degraded conditions?

A "Hot Pipe " sign was found lying on the grating on the 96' elevation of the Unit 2 HPCI Room (on the Unit 2 HPCI Room- Cooler Platform) next to: the 2T41-BOOSA cooler but not attachedto anything.The tag is light and not located near any sensitive equipment, so it is judged 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 of the 2T41-BOO5A cooler. The lead is very light and is attached by 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.

YI NEI UI' N/AD]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 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 demineralized water pipe discovered that appeared to 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 additional supports on either side of the missing support and is light, so it is judged 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'interactions with other equipment in the area (e.g., ceiling tiles and lighting)?

There is a temporary power 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 is judged sufficient to prevent impact between.the cable and any sensitive equipment on the other side of the beam.Therefore, there is no potentially adverse seismic interaction.

YN NE] UE] N/Al1 YM NEI U-- N/Al]If the room in which the SWEL item is located is very large (e.g., Turbine Hall), the area selected should be described.

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)?

There was a 6' metal ladder left unrestrained behind the 2H21-P018 RHR Instrument Rack (CR 522935). The ladder was placed behind the diagonal support for the rack and a steel column, such that during a seismic event, the ladder would not be able to impact anything except support steel. The impact isjudged by the SWEs to be credible but not sign ificant. Therefore, there is no potentially adverse seismic condition.

There are afew items (a plastic bag, a roll of caution tape and a small metal piece) left loose in the contaminated area around the 2E11-C002C RHR Pump. All of the items are small and light and located awayfrom sensitive equipment, so are judged to not create a potentially adverse seismic: condition.

There was a 3' long bent steel support that was sitting on the floor 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 is judged that there is no potentially adverse seismic condition.

There are two brass nozzles sitting loose on top of the Gas Cylinder Location 2P33-P066 and two brass nozzles sitting on the frame for panel 2H21-P405B, which is a~high potential to cause a plant transient (CR 515750). The nozzles are small and relatively light, so they are unlikely to cause any structural damage during a seismic event.However, due to their location on the support for a high trip hazard panel, there is a concern that the nozzles could potentially cause a plant transient.
