H 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 o

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

YN NEI

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

There is one anchor missing from the support. Review of SEWS package 2R42-SOOB shows that this anchor is noted to be missing and is not accounted for in the evaluation, 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.)

9. Do attached lines have adequate flexibility to avoid damage?

The line between the battery rack and the adjacentjunction box support has relatively little slack The battery and box supports are fairly rigid and the seismic, acceleration at that elevation will be relatively low, so the differentiatmovement between the-components will be small. The slack in the conduit is judged sufficient to prevent any damage. to the cables, so there is no potentially adverse seismic condition.

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 two anchor bolt holes without anchor bolts. However, review of SEWS packages 2R42-S026 and S029 show that the anchors were replaced with welds, so there are no missing anchors. The existing welds have been verified against the SEWS packages-and found to be in compliance. Therefore, there is no potentially adverse seismic condition.

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 is one of the 50% for which an anchorage configuration verification is required.)

There are four holes bi the front of the battery charger without screws. The holes a?-e for an internal attachment or grounding configuration that is not being utilized, so there are no scre ws missing.

Therefore, there is no potentially adverse seismic condition.

Components inside the battery charger were inspected visually in accordance with the direction provided in the FAQ related to opening panels per Work Order SNC436314. No potentially adverse seismic conditions were identified.

6. Based, on the above anchorage evaluations, is the anchorage free of potentially adverse seismic conditions?

The Unistrut member supporting the battery charger is bent out from the wall at the far end,of the member. The gap between the wall and the member is less than 1/4", so the gap is not significant. In addition, the bolt attaching the charger to the unistrut channel at that location appeared to be over tightened to the, point that the unistrut is sprung and the lower edge of spring nut no longer makes proper: contact with the inner edge of the unistrut channel (See Figure 3). This condition reduces the connection's strength compared to a properly installed spring, nut connection. The current battery charger is: supported by 3 additional unistrut bolts and a vertical conduit which also provides additional support to the battery charger in the vertical direction.

However CR 520297 has been generatedto correct this condition.

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 YN NI]

of the 50% of SWEL items requiring such verification)?

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

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 is one of the 50%. for which an anchorage configuration verification is required.)

Compared against the SEWS package dated 2/17194. Anchor bolts were confirmed (location, size and quantity).

8. Are overhead equipment, distribution systems, ceiling tiles and lighting, and masonry block walls not likely to collapse. onto:the equipment?

Lighting fixtures might swing and hit the diesel generator but no credible damage is anticipated by SWEs since the light fixture is relatively light and the generator is rugged. Overhead fluorescent light bulbs above the, control panel 2R43-POO3A may potentially hit the panel if they detach from the fixture during a seismic event. However, the impact to the panel was judged not significant since the bulbs are lightweight and the panel is relatively rugged. See attached pictures. The light fixture itself was judged to be adequately restrained

FAIRBANKS MORSE 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 of the 50% of SWEL items requiring such verification)?

YN NEI

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

An anchor bolt on the northwest end of diesel generator had a single nut secured on bolt while others were observed to have two. The second nut is for vibration mitigation. The SEWS package for 2R43-SO01A, dated 02117/1994, evaluates the anchorage for an identical generator and the anchorage assessment does not take credit for the anchor in a similar location. Therefore, it is judged to be seismically adequate based on comparison.

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 is one of the 50% for which an anchorage configuration, verification is required.)

Anchorage configuration is consistent with. SEWS package for 2R43-SO01A, dated 02117/1994, which: contains an attached calculation for 2R43-S001C.

6. Based on the above anchorage evaluations, is the anchorage free of potentially adverse seismic conditions?
