Comments (Additional pages may be added as necessary)

There are several housekeeping issues with Emergency N2 Bottle Rack 1P70-AOO2B. There does not appearto be an NPL tag affixed toi the rack to aidin identifying the item (CR 516094); there is a rolled up sheet ofpaper with a metal tool of some sort (it appearsto be a wrench) in the top left tube steel horizontalmember; there is a bottle cap sitting between two of the bottles at-the base of the rack; andthere is a bottle cap sitting in the back of the rack near the diagonalsupport. 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 and4relativelylight. Duringa seismic eyent, it.is likely: that the items will move from their existing locations,but do not have thepotential to strike anything other than the bottle racksupports due to the location of the rack and its distancefrom any safety relatedSSCs. Therefore, it isjudged to have: no potentiallyadverse seismic condition.

11. Have you looked for and found~no other seismic conditions that could YE] NE UE]

adversely affect the safety functions of the equipment?

Because the duct is insulatedat the damperflange 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 insulationwould be requiredto inspect the flange connection bolts, which are not consideredto be anchoragefor the component.

In addition, The seismic support of the Air Line identified as an iPEEE vulnerability describedin DCR 93-055 has apparently not been completed because the Air pipe is not adequately supported for seismic loads. The end of the hardpipe needs to be attached to an existing Unistrut with a P2558 or equivalent2 bolt pipe clamp (See Figures4, 5 and 6 for details). CR 525292 has been written to addressthis condition.

Interaction Effects

7. Are soft targets free from impact by nearby equipment or structures? YEI NO UE1 N/All 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 initiatedto evaluate and resolve this condition.

8. Are overhead equipment, distribution systems, ceiling tiles and lighting, YZ NEI U-l N/A[I 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 arejudged to be adequate to prevent the tiles from falling during a seismic event.

The overhead equipment, distributionsystems, and lighting were installedwith rigid restraintsor rod hung with multiple tie wires to limit horizontalmovement. The tie wires are also consistent with the IPEEE outlierresolution to prevent the light fixtures from falling (DCR 90-010).

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

There were no bolts at rearvertical side connection of Panel 1-HI 1-P652 to Panel 1-HI11-P651. Five bolts were intalled in the middle verticalsupport member. Also, the bottom bolt on the rearvertical 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 otherbolts were properly installed. The details of these connections areý not specified in the availabledesign documents. Perreview of the SEWS package,,the panel weight is conservatively approximated to be 8300/bs. The maximum horizontal accelerationof the panels 0.75g. The evaluation included in the SEWS package concluded that the floor anchors have sufficient capacity to resist the maximum horizontalacceleration. Therefore, the bolts which connect the panels are required to only restrainthe cabinets so that there is no differentialmovement 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" diameterbolts. The loading of the sides of the panels are distributeddue to the attached terminal strips, electricalcomponents and wires. There are no significantconcentratedloads at the rear edge of the panels.

Therefore, consideringthe maximum capacity of the existing bolts (518" diameter), the loads associatedwith differential movement of the cabinets arejudged 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.

Other Adverse Conditions

11. Haveyou looked for and found no other seismic conditions that could YN NEI UI-adversely affect the safety functions of the equipment?

Components inside the panel were inspected visually in accordance with the directionprovided in the FAQ related to opening panels.

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 Y-I NO of the 50% of SWEL items requiring such verification)?
2. Is the anchorage free of bent, broken, missing or loose hardware? YO NE] Ur] N/AZ The equipment is an inline component, so there is no anchorage.
3. Is the anchorage free of corrosion that is more than mild surface Y0 NE] UE] N/A[Q oxidation?
4. Is the anchorage free of visible cracks in the concrete near the anchors? YZ NEI Ur- N/ArZ
5. Is the anchorage configuration consistent with plant documentation? YE] NC] Ui] N/AE (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 YO NEI UE-potentiallyadverse seismic conditions?

11. Have you looked for and found no other seismic conditions that could Y0 NO' UEI adversely affect the safety functions of the equipment?

There isafallprotection strap left on theESSAirACC (CR 519465).

The strap is wedged between the component andthe supportsteel and is not attachedto any otherfall protectionequipment. It appearsthat the strap could not be removedfrom the support andwas.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*potentiallyadverse seismic condition.

Comments (Additional pages may be added as necessary)

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