The seismic capacity of the Concrete Block Walls C130-47E, C-139-54A, C130-51B, and C130-52A surrounding the component has been verified via drawing H-40383, Rev. 2 and Hatch Unit 2, UFSAR Table 318-20.There is afluorescent light fixture without a cover located over the component.

The light is tied to the ceiling; so during a seismic event, only the bulb could fall. The motor generator is very rugged and is judged to have sufficient strength as to make a possible impact between the motor generator and the bulb will be insignificant.

Therefore, it is judged to be seismically adequate by the SWE's.9. Do attached lines have adequate flexibility to avoid damage?Motion of the vibration isolators during a-seismic eent is considered small.

There are a number of drilled holes in the casing of the motor, particularly at anchorage locations.

These holes appear to have been drilled to alter the balance of the motor and are clearly unrelated to component anchorage.

Their presence does not indicate missing anchors or screws. Therefore, there is no potentially adverse seismic condition.

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)?

.2. Is the anchorage free of bent,. broken, missing or loose hardware?There, are several locations where the original anchor bolts have been replaced with a different anchor bolt type, including one location where a second hole was drilled in the frame. This replacement is addressed in the SEWS package, andso is acceptable.

The empty hole is for an abandoned anchor bolt, and the -existing anchors are consistent with the plant documentation, so there is no potentially adverse seismic condition.

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

There is some acid residue on the bolts from the batteries, but the paint has prevented any significant corrosion of the bolts. Since the corrosion is only on the surface, there is no potentially adverse seismic condition.

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.)
