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 YE NZ of the 50% of SWEL items requiring such verification)?
2. Is the anchorage free of bent, broken, missing or loose hardware? YN NEI UE- N/AEl
3. Is the anchorage free of corrosion that is more than mild surface YED NEI UE N/AE1 oxidation?
4. Is the anchorage free of visible cracks in the concrete near the anchors? YZ NE- UD N/AEl
5. Is the anchorage configuration consistent withplant documentation? YE NEI UE- N/AZ (Note: This question only applies if the item is one of the 50% for which an anchorage configuration verification is required.)

7. Are soft targets free from impact by nearby equipment or structures? YN NEil UO N/AEl
8. Are overhead equipment, distribution systems, ceiling tiles and lighting, YO NE UE] N/A[l and masonry block walls not likely to collapse onto the:equipment?

The seismic capacityof the ConcreteBlock Walls C130-47E, C130-50B, C130-51A and C130-54A surroundingthe Motor Generatorwere verified using DrawingH-40383 Rev. 2 andHatch Unit 2 UFSAR Table 3.8-20.

There is afluorescentlightfixture without a cover locatedover the component. The light is tied to the ceiling,so during a seismic event, only the bulb couldfall. The motor generatoris very ruggedand is judged to have sufficient strength as to make a possible impact between the motor generatorand the bulb will be insignificant. Therefore, it is judged to be seismically adequate.

9. Do attached lines have adequate flexibility to avoid damage? YI NEI U0 N/AEl There is a section offlex conduit between the motor generatorand a conduit support with limited slack. The motor generatoris rigidly attachedto the floor and has a low center of gravity, and the conduit support is rigidly attachedto the floor. Therefore, there will not be.

much differential movement between the two ends of the flex conduit.

The existing slack isjudge to besufficientfor the very small differential movement, so there is no potentially adverse seismic condition.

10. Based on the above seismic interaction evaluations, is equipment free YZ NEI UFE of potentially adverse seismic interaction effects?

Other Adverse Conditions

11. Have you looked for and found no other seismic conditions that could YZ NEIU1-adversely affect the safety functions of the equipment?

There are a numberof drilledholes in the casing of the motor, particularlyat anchorage locations. These holes appearto have been drilled to alter the balanceof the motor and are;clearlyunrelatedto component anchorage. Their presence does not indicate missing anchorsor screws. Therefore, there is no potentially adverse seismic condition.

This equipment was originallyidentifiedas:A-46 & IPEEE outlierdue to the following; 1. A potential bolt bending concern due to the gap the floor and base support members. 2. Potentialinteraction with overhead light fixtures.

Shims were observed to have been installed (DCR 89-261) to provide fullcontact between the bolts. Support members and concretestructure as shown in the attachedpicture.

The lights were attached (DCR 90-010) in such a way that there are two wires supporting the light structureand two brackets supporting the bulb housing as shown in the attachedfigure.

3. Is the anchorage free of corrosion that is more than mild surface Y21 NOl UOI N/AZ oxidation?

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