Comments (Additional pages may be added as necessary)

There are several housekeeping issues with Emergency N2 Bottle Rack 1P70-AOO2B. There does not appear to be an NPL tag affixed toi the rack to aid in identifying the item (CR 516094); there is a rolled up sheet ofpaper with a metal tool of some sort (it appears to be a wrench) in the top left tube steel horizontal member; there is a bottle cap sitting between two of the bottles at-the base of the rack; and there is a bottle cap sitting in the back of the rack near the diagonal support. In addition, there is a section of chain at the back of the rack at the same location as the bottle cap. All of these items are small and4relatively light. During a seismic eyent, it. is likely: that the items will move from their existing locations, but do not have the potential to strike anything other than the bottle rack supports due to the location of the rack and its distance from any safety related SSCs. Therefore, it isjudged to have: 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)?

This component is a inline air operated HVAC Damper that is insulated.

These components are manufacturer supplied components which come designed for seismic conditions described by the plant seismic response.

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?

Inline air operated HVAC damper not anchored in concrete.

5. Is the anchorage configuration consistent with plant documentation?

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

Because the duct is insulated at the damper flange connection the flange connection bolts could not be checked for broken, missing or loose hardware. All visible surfaces were inspected and no potential adverse conditions were found. Disassembly of the insulation would be required to inspect the flange connection bolts, which are not considered to be anchorage for the component.

In addition, The seismic support of the Air Line identified as an iPEEE vulnerability described in DCR 93-055 has apparently not been completed because the Air pipe is not adequately supported for seismic loads. The end of the hard pipe needs to be attached to an existing Unistrut with a P2558 or equivalent 2 bolt pipe clamp (See Figures 4, 5 and 6 for details). CR 525292 has been written to address this condition.

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

There is a flexible conduit section between the top of the pump and a rigid conduit section above the pump that is fairly tight. It is judged that the flex conduit can deflect 1" without putting significant stress on the conduit. SWE'sjudge that the pump will move less than. 0.5" during a seismic event.due to the elevation. and rigidity of the equipment Calculation SCNH-91-069 Rev. Ofor the adjacent RH7R pump of the same type gives a maximum pwnp deflection of less than 0.2" at thetop of the pump, Therefore, it isjudged that the line has adequate flexibility for the pump seismic deflections.

7. Are soft targets free from impact by nearby equipment or structures?

Long florescent light bulbs inside the panel have no covers or restraints., The florescent light bulbs may become loose during a seismic event and impact wires and components inside the cabinet.

According to the SEWS package, this panel contains essential relays that could be potentially impacted. CR # 520462 was initiated to evaluate and resolve this condition.

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

A ladder was used and permission obtained to remove the ceiling panels near 1-H11-P652. The frames for the ceiling tiles are judged to be adequate to prevent the tiles from falling during a seismic event.

The overhead equipment, distribution systems, and lighting were installed with rigid restraints or rod hung with multiple tie wires to limit horizontal movement. The tie wires are also consistent with the IPEEE outlier resolution to prevent the light fixtures from falling (DCR 90-010).

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

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

There were no bolts at rear vertical side connection of Panel 1-HI 1-P652 to Panel 1-HI 11-P651. Five bolts were intalled in the middle vertical support member. Also, the bottom bolt on the rear vertical side connection of Panel 1-Hl I-P652 to Panel 1-HI 1-P600 does not have full thread engagement. Only approximately 2 threads are engaged in the nut' (See Picture #3). All other bolts were properly installed. The details of these connections areý not specified in the available design documents. Per review of the SEWS package,, the panel weight is conservatively approximated to be 8300/bs. The maximum horizontal acceleration of the panels 0.75g. The evaluation included in the SEWS package concluded that the floor anchors have sufficient capacity to resist the maximum horizontal acceleration. Therefore, the bolts which connect the panels are required to only restrain the cabinets so that there is no differential movement and consequent banging of the panels.

Both. sides of Panel 1-HI I-P652 are also attached to the adjacent panels at the lower front sides with two 518" diameter bolts. The loading of the sides of the panels are distributed due to the attached terminal strips, electrical components and wires. There are no significant concentrated loads at the rear edge of the panels.

Therefore, considering the maximum capacity of the existing bolts (518" diameter), the loads associated with differential movement of the cabinets are judged to be adequately restrained. The rear vertical connection of Panel 1-H1 I-P652 to Panel 1-HI 1-P652 does not need to be enhanced and the bolt with less than optimal thread engagement does not need to be replaced.

There is one empty hole at the top of the battery charger for an additional grounding line that is not being utilized, so no bolt is missing from the hole. Therefore, this is not a potentially adverse seismic condition, and no other potentially adverse seismic conditions were identified.

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 providedat 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?

The equipment is an inline component, so there is no anchorage.

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

6. Based on the above anchorage evaluations, is the: anchorage free of potentiallyadverse seismic conditions?

There isa fall protection strap left on theESSAirACC (CR 519465).

The strap is wedged between the component and the support steel and is not attached to any other fall protection equipment. It appears that the strap could not be removed from the support and was. abandoned The strap is very light and is not near any sensitive parts of the component, so it isjudged that the strap does not have the ability to create a*potentially adverse seismic condition.

Comments (Additional pages may be added as necessary)

There does not appear to be an MPL tag affixed to the ESS AirACC 1P52-AO01 to aid in identifying the item (CR 519468).,
