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)?
Anchorage is only partially visible, therefore not chosen for 50%verification.
- 2. Is the anchorage free of bent, broken, missing or loose hardware?Visible anchors at the front section of the panel are acceptable.
Anchors at the rear of the cabinet are not visible. It was noted that panels A 6-5, A 6-9 and A 6-11 had spalling concrete around the anchors at the front. Panel A6-11 also had an anchor abandoned in place and appeared missing at first glance. This was detailed in the SEWs package dated 3/13/98 and further clarified in FRN 96-01-136A, -136B, and -136C. The anchors with spalling concrete have been replaced with longer, 6" embedment anchors, which have full capacity.
The abandoned anchor was noted to be a replacement anchor for previous outlier concerns, and was damage during installation.
The result was to cut off the anchor and abandon it in place. Based on the SEWs analysis and FRN's, the anchorage of the panel is acceptable.
A nut securing a wire chase to the side of the panel in cabinet A6-6 is loose and not fully engaged to the washer. It is located inside the cabinet on the top left side. Although not a seismic hazard CR-PNP-2012-04547 was written to correct the issue.3. Is the anchorage free of corrosion that is more than mild surface oxidation?
On visible anchorage, no oxidation was noted.4. Is the anchorage free of visible cracks in the concrete near the anchors?YI-- N[R YN NEI ULI N/AF]Y[ NDI Ur- N/A[-Y[ NEI U[- N/A[l Concrete surrounding visible anchors was free of cracking.'Enter the equipment class name from Appendix B: Classes of Equipment.

Y[I NE] U[I N/AZ (Note: This question only applies if the item is one of the 50% for which an anchorage configuration verification is required.)
Although only anchors in the front of the panel were visible, their location was verified by sketches in the SEWs package as well as FRN's 96-01-136A through -136C.6. Based on the above anchorage evaluations, is the anchorage free of Y; NE] U[E]potentially adverse seismic conditions?
Interaction Effects 7. Are soft targets free from impact by nearby equipment or structures?
Previously noted outliers from A-46 such as conduit tray touching the cabinet were noted to be resolved by adding clips to attach the two items, making it seismically acceptable.
A sheet metal plate located on the top of the inside of panel A6-6 is secured by two bolts, both on one side of the plate. There are holes for the remaining 4 bolt holes, which appear to be missing. This is not a seismic hazard as it is not likely to fall and is not touching any critical relays in its current position, but engineering judgment suggests that the bolts should be properly added for adequate anchorage.
CR-PNP-2012-04550 was written to address this item.8. Are overhead equipment, distribution systems, ceiling tiles and lighting, and masonry block walls not likely to collapse onto the equipment?
- 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?Cabinet A6-11 has a broken tag on the front exterior of the cabinet that reads "Diesel Generator Voltage Balance".
This is not a seismic hazard. Operations was notified and a request was created in eSOMS.A plastic equipment tag label, tagged 163, in A6-3 is hanging by a single bolt. Originally it appeared to be secured by two, but now it only has one. This is not a seismic hazard.CR-PNP-201-04551was written to address both these items.YO NE] urE] N/AE]YZ NE:] UE] N/A[]YZ NE] Ur-] N/AE]YZ NE] UE EN-DC-168 REV 0 Engineering Report No. PNPS-CS-12-00001, Rev. 1 Attachment C Page C334 of C413 ATTACHMENT

- 11. Have you looked for and found no other seismic conditions that could YZ NW] U-adversely affect the safety functions of the equipment?
Cabinet A6-5 is missing a bolt on the exterior upper portion of the panel. Cabinet A6-11 is also missing two bolts on the exterior upper portion of the panel. Previous operations guidance specified that these bolts were only used during shipment of the panels en route to the plant, therefore not a seismic hazard.The back of cabinet A6 is missing one bolt and one bolt is not fully engaged and appears to be hanging out of the top portion of the panel.Due to redundant anchorage of panels, this is not a seismic hazard.CR-PNP-2012-04549 was written to address these items.Comments (Additional pages may be added as necessary)

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)?
Cabinet is anchored to the floor, but anchorage is not visible due to inability to open lower half of panel until an outage, therefore, this was not chosen for the 50% verification.

YEI NE] UE] N/AN (Note: This question only applies if the item is one of the 50% for which an anchorage configuration verification is required.)
Refer to question #1.6. Based on the above anchorage evaluations, is the anchorage free of YE NEI U-IJ potentially adverse seismic conditions?
Interaction Effects 7. Are soft targets free from impact by nearby equipment or structures?
There is a cart, wires and tools near the cabinet, but is adequately marked as work in progress, with the cart wheel choked, therefore acceptable.
- 8. Are overhead equipment, distribution systems, ceiling tiles and lighting, and masonry block walls not likely to collapse onto the equipment?
The masonry block wall behind the panel, #210.0 (C967Sh I), is safety related, therefore seismically qualified and acceptable.
- 9. Do attached lines have adequate flexibility to avoid damage?A 2" rigid conduit spans horizontally between panels D-4 and D-16 in the upper switchgear room. Panel D-4 is wall mounted while panel D- 16 is floor mounted. The concern is for differential seismic motion between panels potentially causing damage to cables inside the cabinets.Because the cabinets are within two feet of each other they would see the same vertical seismic acceleration and displacement.
Horizontal displacement of the floor mounted panel could be higher than the wall mounted cabinet, however both panels are very stiff and well anchored.Any differential seismic displacement would be relieved by the inherent flexibility of screwed conduit connections at each panel. There may be some local deformation of the walls of the panels where the conduits enter but not enough to cause any damage to the cables inside. These panels do not contain any essential relays. Therefore during a seismic event, the panels will be able to perform their intended functions.

A small box of lightbulbs used by operations or maintenance was found behind the panel, sitting on the Unistrut.
Due to the size of the box and lightweight, this is not a seismic or safety concern.Interaction Effects 7. Are soft targets free from impact by nearby equipment or structures?
Junction box J2289 is mounted to the underside of cable tray in the overhead.
The cover of the box is missing five of eight fasteners.
Due to the light weight of the cover, it is not hanging down from the box, nor does it pose a seismic hazard.CR-PNP-2012-04665 was written to replace the bolts.8. Are overhead equipment, distribution systems, ceiling tiles and lighting, and masonry block walls not likely to collapse onto the equipment?

Spot checked dimensions, bolts size and anchorage configuration against C103, El.6. Based on the above anchorage evaluations, is the anchorage free of Y[ ND UFD potentially adverse seismic conditions?
Interaction Effects 7. Are soft targets free from impact by nearby equipment or structures?
Scaffold built over SWELl-101 equipment.
Scaffold 11-279 (see attached photo) is a long term safety related, seismic scaffold evaluated and approved in accordance with EN-MA-133.
- 8. Are overhead equipment, distribution systems, ceiling tiles and lighting, and masonry block walls not likely to collapse onto the equipment?
Light on west side on a long chain. This item is not likely to collapse due to its light mass and relatively large period of oscillation.
- 9. Do attached lines have adequate flexibility to avoid damage?Fire piping does not have 3" clearance with scaffold (see attached photo). Scaffold log 11-279 notes this condition and deems the pipe riser acceptable based on the small seismic displacements anticipated for the scaffold.10.
