The hood at the top of the damper has two bolts on the west side that are not properdy fastened.

The bolt to the north is bent while the bolt to the south is not tight and the hole is oversized (see photographs 4 and 5). Neither bolt has nuts that are fully engaged. The two bolts on the east side are properly fastened.

The hood is not a vital aspect for the operability of the fan ifthe connection were to fail during a seismic event. However, the bolts need to be properly installed.

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 ofjudgments and findings.

Additional space is provided at the end of this checklist for documenting other comments.Anchorage I.. Is the anchorage configuration verification required (i.e., is the item one of the 50% of SWEL items requiring such verification)?

2. Is the anchorage free of bent, broken, missing or loose hardware?At the louver on the roof, one of the bolts fastening the housing to the concrete pedestal has missing washers. However, this was judged not to be: a seismic concern since washers are not vital for the seismic performance of an anchor bolt. Washers are not required for installations using mild steel bolts and plates without oversized holes.Hole is not oversized based on observation.

Also for the housing of 1X41-COO9B, there are missing screws on the side as shown in the pictures.

This was judged not to be an issue since there is nothing for the screws to attach to at this location.

The holes are not a concern because the overhanging portion ofthe housing prevents the water intrusion.

See attached pictures.3. Isthe anchorage free of corrosion that is more than mild surface oxidation?

4. Is the anchorage free of visible cracks in the concrete near the anchors?5. Is the anchorage configuration consistent with plant documentation?(Note: This question only applies if the item isone of the 50% for which an anchorage configuration verification is required.)

Anchorage was compared against Dwg H-12613, Rev. 13 and SQUG package dated 7/22193. The housing at the roof is not a seismically qualified portion of the equipment.

SQUG package only included evaluation of bolts inside the intake.6. Based on the above anchorage evaluations, is the anchorage free of potentially adverse seismic conditions?

There is insulation removed from a pipe attached to the equipment which was not replaced and stored imporperly (see photograph 3).This is not a seismic concem. CR 524535 has.been written to replace the insulation:

properly.There is a steel frame supporting a large insulated duct from the air handler that exhibits corrosion that is more than mild (see photograph 4). The corroded steel does not extend beyond the immediate surface.The remaining steel does not exhibit the same: corrosive appearance.

The weight of the duct and insulation is low with respect to the steel frame's capacity byjudgement.

In its current condition, the support is judged to be seismically adequate.YN NEI UE" Comments (Additional pages may be added as necessary)

SQUG walkdown identified equipment to have steel tabs welded to the existing steel frame for the equipment, which were to be anchored to the concrete roof This was observed to be installed during the walkdown.See. Z41-FOO9B for AWC information.

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 ofjudgments 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 Y 0 Nr-]of the 50% of SWEL items requiring such verification)?

2. Is the anchorage free of bent, broken, missing or loose hardware?

YZ N[ UE] N/AE]Housing of the equipment has 4 screws missing in the back which attach the housing to the interior frame. There are 18 screws present.Therefore, this is judged not to be a seismic concem.CR523730 was initiated to replace these screws.SWEs judged this not to be a seismic concern due to the presence of multiple screws present Three bolts on the side (next to the staircase, underneath the edge) are missing. CR518594 was initiated to replace these bolts.S WEs judged this not to be a seismic concern due to the presence of more than 10 bolts (side and back).Bolts attaching the unit to the below steel members were found bent and holes were found without bolts.Per the SQUG evaluation and Drawing B-43459, Rev. D, the original anchor bolts have been replaced with four Welded steel tube members. The bolts were allowed to be removed orabandoned in place. The original anchorage was also identified as an IPEEE vulnerability.

It was verified that theý 4 steel tube.members are present and welded to below framing and the equipment.

Two loose bolts were found on the back of the equipment attaching the framing to the support. One of these bolts is near a welded portion, so it can not be tightened, this is okay due to the existing weld. This was judged not be a seismic concern due to the sheer number of existing bolts/scres present.Four long bolts underneath the cooler fan were observed.

However, they were qualified by the SQUG walkdown package dated 11/5/88.The anchors were verified to match the information in the SQUG package (See Sheet 7).1 Enter the equipment class name from Appendix B: Classes of Equipment.

There is mild surface corrosion on the channels on the back of the equipment However, this is judged not be a seismic issue since it is only mild surface corrosion.

4. Is the anchorage free of visible cracks in the concrete near the anchors?5. Is the anchorage configuration consistent with plant documentation?(Note: This question only applies if the item is one of the 50% for which an anchorage configuration verification is required.)

Anchorage was compared against the SQUG package dated 11/5188 and Drawing B-43459, Sheet 1, Rev. 0.6. Based' on the above anchorage evaluations, is the anchorage free of potentially adverse seismic conditions?

YI- NZ 2. Is the anchorage free of bent, broken, missing or loose hardware?1 of the 16 bolts on the single train anchorage is too short, does not go through the nut completely.

The equipment is wide and heavy, therefore little or no tension load is anticipated in the anchor bolts.Remaining bolts on the same side of the equipment are adequate to take any shear if needed. Therefore, the SWEs judged that the overall equipment anchorage is seismically adequate.3. Is the anchorage free of corrosion that is more than mild surface oxidation?

4. Is the anchorage free of visible cracks in the concrete near the anchors?5. Is the anchorage configuration consistent With plant.documentation?(Note: This question only applies if the item isone of the 50% for which an anchorage configuration verification is required.)

2. Is the anchorage free of bent, broken, missing or loose hardware?There are compression washers and double nuts missing at the south side of 1Z4 1-BOO8A (see photographs 3 and 4). The missing hardware is on the outer portion of the support pedestal.

The inside hardware is presenL The unit is supported vertically by the pedestal and the inside connections prevent uplift and vibration mitigation as intended.

It is judged to be seismically adequate, however, the redundancy of the second hardware set should be replaced.
