Instructions for Completing Checklist This checklist may be used to document the results of the Seismic Walkdown of an item of equipment on the SWEL. 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.Anchorage 1. Is the anchorage configuration verification required (i.e., is the item one of the 50% of SWEL items requiring such verification)?

YE Nil Yes, check the anchorage.

2. Is the anchorage free of bent, broken, missing or loose hardware?Several bolts lacked full engagment (approximately one thread is not engaged).

This is judged to be acceptable.

3. Is the anchorage free of corrosion that is more than mild surface oxidation?

Some bolts exhibit slightly more than mild surface oxidation.

The condition is not advanced and bolts should be cleaned and coated to provide protection against further deterioration.

The current condition is considered acceptable.

CR-IP3-2012-03236 has been issued to remedy this condition.

4. Is the anchorage free of visible cracks in the concrete near the anchors?Minor tight surface cracks were identified on the RWST-31 foundation.

The cracks are not near the anchors and are judged to be acceptable as they seem to be normal concrete shrinkage cracks.I Enter the equipment class name from EPRI 1025286, Appendix B: Classes of Equipment.

YE] NE UEL N/AL](Note: This question only applies if the item is one of the 50% for which an anchorage configuration verification is required.)

Anchor bolt spacing is 4Y 2" vs 3" as indicated on drawing 9321-F-19543, Section K-K. The base plate size is equal to 4" x Y2" x O-9" vs.drawing at 6"x Y2"x 0'-10".6. Based on the above anchorage evaluations, is the anchorage free of Y[ NOi U-I potentially adverse seismic conditions?

The increase anchor bolt spacing will provide greater out of plane moment capacity and is conservative.

The decrease in base plate size is not critical since the assembly will act as a rigid frame and the component integrity will not be compromised since the base plates will be loaded primarily in compression and the decrease in bearing capacity is not considered significant for the minimum weight of the component.

A closer review determined that the speakers could not impact the valves. Therefore, this is not a seismic concern.Comments (Additional pages may be added as necessary)

Observed a crack crossing the east bolt of a conduit support on the north wall for conduits coming out of Relay Box TR-2 KOO. The conduit support consist of a P1000 Unistrut with two 3/8" diameter bolts supporting

=1Y2" and -4" diameter conduits (see attached photos). A sketch of the crack and the support is shown below for clarification.

This is evaluated in LB-16.P1000 Unistrut 3/8" dia. bolt Observed a Unistrut connection angle clip has play in it which allows the spring nut in the Unistrut to wiggle and not tighten the bolt. The tube track is adjacent to the heater 25 in the Control building elevation

15. This allows the unistrut to wiggle but is still operable.

Not a seismic interaction issue since it will not dislodge and small load. This is documented in CR-IP3-2012-3416.

Yes, anchorage of equipment in the area appears to be free of potentially adverse seismic conditions.

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

Yes, anchorage of equipment in the area appears to be free of significant degraded conditions.

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)?A pipe support immediately adjacent to Appendix R cabinet ERB-47-ABFP that is attached to the ceiling has a base plate with six holes but only four bolts are installed (see attached photo). CR-IP3-2012-03580 was written to evaluate this condition.

Does it appear that the area is free of potentially adverse seismic YOI NO UI- N/AOI-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 waterline 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 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.

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. CR-IP3-2012-03473 was issued to remedy this situation.

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. See attached photo.-Since weight of the closure panel is less than 40#, and peak acceleration from ground response spectra is 0.64, 14 out of 22 screws are more than adequate to hold the panel in place.All the conduit and pipes show sign of corrosion.

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/" to X" (see attached photo). Per procedure O-RES-400-GEN, the allowable gap shall not be greater than 3132". This '/8" to Y." gap may result in bending of the anchor bolts. This is addressed in CR-IP3-2012-03361.

Yes, anchorage of equipment in the area appears to be free of significant degraded conditions.

The wire trough is attached two Unistruts channels with one Unistrut bolt on each channel at the top. There is an approximately Y." 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.

This is addressed in CR-IP3-2012-03363.
