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 torecord 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 Y0 NE of the 50% of SWEL items requiring such verification)?
2. Is the anchorage free of bent, broken, missing or loose hardware? YI NO U- N/AEl
3. Is the anchorage free of corrosion that is more than-mild surface, YN NEI UOZ N/AEl oxidation?

There is mild surface oxidation on the welds. Since oxidation is only on the surface, the welds are not degraded. Therefore,judged not to be a concern.

4. Is the anchorage, free of visible cracks in the concrete near the anchors? YN NEI UO N/AI-
5. Is the anchorage configuration consistent with plant documentation? Y19 NEI UI N/AU (Note: This question only applies if the item is one of the 50% for which an anchorage configuration verification is required.)

SEWS Package JR]I-S004 (dated 10/20/88) andCalculation SCNH-98-070 Rev. 0

6. Based on the above anchorage evaluations, is the anchorage free of YN NO UU potentially adverse seismic conditions?

This. component has been inspectedto the extent practical. All visible anchors, hardwareand surfaces were inspected. The anchoragefor this item is visible without openingthe component. To inspect the componentfurther would require disassembly. Since the anchorageis visible, the inspection meets the requirements of the guidance document.

Anchorage

1. Is the anchorage configuration verification required (i.e., is the item one YN NEI of the 50% of SWEL items requiring such verification)?

This component has been inspected to the extent practical. All visible anchors,hardware andsurfaces were inspected. The anchoragefor this item is visible without openingthe component. To inspect the componentfurther would require disassembly. Since the anchorageis visible, the inspection meets the requirements of the guidance document,

2. Is the anchorage free of bent, broken, missing or loose hardware? YN NEI U[" N/Al]

There is a loose nut on the back left anchor boltfor the transformer.

This condition is addressedandfound to be acceptable in the referencedSEWSpackage, so there is no potentially adverse seismic condition.

Comments (Additional pages may beadded as necessary)

There is a coil of rope left behind transformer JRI-S041 (CR 524319). The rope is relatively light and is not close to anything except the angle supportsfor the transformer,but not the transformer itself,so there is no potentiallyadverse seismic condition. The rope shouldbe moved to the equipment storage areaset up on the other side of the room.

The thread engagement on the southwest bolt of the pump support shows approximatelyone threadexposed above the nut ratherthan the minimum, of two threads. The SWE's have judged that there is sufficient threadengagement between the bolt and the nut for seismic restraint,so there is no potentiallyadverse seismic condition.

3. Is the anchorage free of corrosion that is more than mild surface YN NEI UEl N/AU-oxidation?
4. Is the anchorage free of visible cracks in the concrete near the anchors? YN NEI U[J N/AEl

There are several threadedholes in the pump frame that do not have anchorbolts. Based on a.review of the frame and Drawing,H-1 5367 Rev. H1, it is determinedthat the holes arefor lifting lugs, and that.no anchorsare missing. Therefore, there is no potentiallyadverse seismic condition.

Comments (Additional pages may be added as necessary)

There is an oil absorbenttowel left loose on thefloor inside the knee wall near the ladderaccess to the pump. The towel is very small and light, and is located in the concrete trench aroundthe pump area,so there is no potentialfor the towel to have any impact on nearby equipment. Therefore, the SWEs havejudged that there is no potentially adverse seismic condition, See Component 1C41-CO01Afor Area Walk-by Checklist.
