SWELl-030, 031 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 adverse seismic conditions (if visible without necessarily opening cabinets)?

Panel (PID 08219) adjacent to the door: Unistrut legs corroded and broken at the base (see attach photos). The toe plate at the floor penetration between the Unistrut legs is loose and is not protecting the opening (see attach photo).Service Water Pumps Annubars has rotted out at the base. The panel lacks of lateral restraints and is free to displace laterally.

Piping grout penetration protection was found cracked and chipped at various locations allowing water seepage (see photos).Outer section of the grout, external o the base plate, for SWP 34 is cracked and missing. This does not affect the integrity of the support of the pump.The above conditions are addressed by CR-IP3-2012-03166.

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

YO N[ UD- N/A[-]YDI NO U- N/A-See above.I If the room in which the SWEL item is located is very large (e.g., Turbine Hall), the area selected should be described.

SWELl-030, 031 3. Based on a visual inspection from the floor, do the cable/conduit YD- NE u[:] N/AD 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)?Floor grating behind the electrical panels is not fixed to the structural steel and could displace laterally.

In addition, this grating also serves as a support for conduits at the level below. Displacement of the grating would affect the support for the conduits.

This condition is addressed by CR-IP3-2012-03166.

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)?

Yes, it appears that the area is free of potentially adverse seismic spatial interactions with other equipment in the area.5. Does it appear that the area is free of potentially adverse seismic interactions that could cause flooding or spray in the area?Yes, it appears that the area is free of potentially adverse seismic interactions that could cause flooding or spray in the area.6. Does it appear that the area is free of potentially adverse seismic interactions that could cause a fire in the area?Yes, it appears that the area is free of potentially adverse seismic interactions that could cause a fire in the area.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)?

Observed a phone and a tool box resting on the web of a beam wall.The phone and the tool box are restrained by the two beam flanges.This is judged acceptable.

Observed a loose scaffold pole (on the floor) beneath a wall beam.During a seismic event the pole may act as a missile and strike nearby equipment.

This is addressed by CR-IP3-2012-03166.

SWELI-030, 031 8. Have you looked for and found no other seismic conditions that could Y-I NE U-I adversely affect the safety functions of the equipment in the area?Ceiling of the area consists of grating which, if not attached to the support steel could fall and impact the equipment.

It was determined that the grating is adequately supported and would not be displaced by a seismic event.Electric Heat Trace Cabinet 31 has abraded cables at the top of the cabinet. The back of the cabinet is mildly corroded at the back/bottom.

A box of bulbs is loose on the inside of the cabinet. An unsecured tag is on a shelf in the cabinet. A brown spot on the back of the cabinet may be the result of a buming effect due to high temperature.

Electrical needs to investigate.

The cabinet is addressed by CR-IP3-2012-03166.

Does it appear that the area is free of potentially adverse seismic YDI NE UD- N/AD-interactions that could cause flooding or spray in the area?Branch risers from the main fire water line are threaded pipe and pass in close proximity (estimate 1" +/-) to large conduit. The conduit is well supported and the fire water line would have to move axially to cause an impact. The vertical rise of the pipe is very short so it is judged that the impact will not occur. See photos.The sprinkler heads are at one location also in close proximity (estimate less than one inch) of adjacent conduit and could interact with the adjacent conduit in a seismic event. See photo.LB-18 was generated to evaluate this condition.

See attached photo. CR IP3-2012-03627 was written to address this condition.

The pipe is a non-safety related pipe.If the pipe were to collapse, it would hang at the top of the monorail.The pipe is on top of a door and there is no equipment near the door.Chemical feed line pipe insulation at CF-44-2 is in contact with the support frame and heater. This is not considered a problem since the insulation around the pipe has a substantially greater diameter than the encased pipe and the insulation would be expected to flex and relieve any force that would be exerted on the pipe.Insulation at CF-133 and Cf-44-4 is missing.If the room in which the SWEL item is located is very large (e.g., Turbine Hall), the area selected should be described.

Caps from nitrogen tanks are on the floor adjacent to and unsecured.

See photo. By engineering judgement, this is not considered an critical seismic issue since seismic induced displacement will not result in the caps impacting critical components.

CR-IP3-2012-03457 was issued to remedy this situation.

Floor grating is not attached to the steel support beams. Most grating is restrained laterally by the pipe supports and the wall on the opposite side. However some panels are only restrained by the wall and could displace laterally under seismic action. Adjacent panels cannot restrain the loose panels because the toe board is not continuous but is attached to each individual panel. They could then impact the main steam lines.

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

The base plates of support columns on adjacent platforms have four holes in the base plates but only two anchors installed on diagonal holes. This condition is judged to be acceptable based on the low height of the platform and the minimum weight of the framing and fiberglass grating.2. Does anchorage of equipment in the area appear to be free of significant degraded conditions?

Several screws are missing from the face closures of the electric panels.

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

Observed a wide flange across the room (spanning east-west) supporting air intake piping with gaps between the base plate and the wall. The gaps are observed to be approximately between 1/8" to 1/4" (see attached photo). Per procedure O-RES-400-GEN, the allowable gap shall not be greater than 3/32". This 1/8" to Y4" gap may result in bending of the anchor bolts. This is addressed in CR-IP3-2012-03361.

The wire trough is attached two Unistruts channels with one Unistrut bolt on each channel at the top. There is an approximately Y4" to 1" gap between the wire trough and the Unistrut (see photos). The wire trough seems to be light in weigh; however, during a seismic event the trough may dislodge and strike nearby equipment.

The wire trough should be properly secured to prevent any adverse seismic conditions.

Does anchorage of equipment in the area appear to be free of YE ND-- ULI N/AD potentially adverse seismic conditions (if visible without necessarily opening cabinets)?

TR-4004 support base plate is missing two out of four anchor bolts.This is typical of all four base plates and based on the size of the cabinet, it is judged that this configuration is adequate for applied seismic loading.2. Does anchorage of equipment in the area appear to be free of YDI NE UD N/AD significant degraded conditions?

Electric heat tracing cabinet support base plates and anchor bolts are severely corroded.

The Unistrut support column has been welded to the stair stringer to provide additional support. CR-IP3-2012-03595 documents this condition.

LB-19 has evaluated this condition.

3. Based on a visual inspection from the floor, do the cable/conduit YE ND- UD N/AD 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)?Fluorescent tubes need to be restrained.

This is a not a seismic adverse condition since equipment in the area are noted as hard targets. CR-IP3-2012-03595 has been written to remedy this condition.

The ladders at the entrance to the Nonregenerative Heat Exchanger Room need to be secured. This is not a seismic adverse concern since the ladders are not near any sensitive equipment.

Good practice is to tie the ladders to the support frame. CR-IP3-2012-03501 has been written to investigate this condition.

The following observation relate to duct FR-DF-40: " The vise grips used to hold the seams on duct need to be replaced with a permanent corrective solution." One wall of the above duct is totally separated from the vertical comer and is flapping freely.The wall of the duct is light in weight and will not damage the nearby boric acid tank. In addition, total separation from the duct is unlikely;therefore, this is judged to have no adverse seismic condition.

CR-IP3-2012-03595 has been written to correct these conditions.

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.

A pipe hanger is close (approx Y 2") to a conduit. See photo for location.The seismically designed conduit is very rigid and will have less than 0. 1 "seismic displacement.

The nearby hanger rod is for dead weight only but the pipe is seismically restrained so the lateral displacement will also be small. The Y" clearance is judged to be acceptable.

In the South-east comer of the room there are pallets of drums and a vacuum that are all unrestrained.

The drums and vacuum are remote from any equipment and this is not judged to be an adverse seismic condition.

CR-IP3-2012-03501 has been written to address this condition.

There is a hot water heater adjacent to the concrete column near Boric Acid Tank 31 which does not have any apparent anchorage.
