Two cases were observed where conduit spans appearedto be longer than standardpractice (seepictures 1 and 2). However, those spans were judged to meet the intent of section 8.0 of the SQUG GIP which allows spans of 20 feet for conduits of this size. Thus, the conduits are seismically adequate.

Conduits 3" and largerare seismically acceptable when the vertical spacing is less than 20 feet (section 8.2.2, SQUG GIP).

Distributionpanels 2R25-SO06 and2R25-SO31 have a screw missing in the front panel. CR #515500 was written to add a screw to panel 2R25-S006 and CR # 515506 was written to add a screw to panel 2R25-S031.

Timer panel 2H2 1-P305 had 5 missing slip connectors to keep the door of the cabinet closed. DOEJ-HX-35281-COO1 "EvaluateCapacity of 4 Screws to Hold Door in Place"addressedthis condition and it has been determined tobe adequate in a seismic event. CR #516713 has been written to resolve this.issue.

Comments (Additional pages may be added as necessary),

Several cable trays exhibited warping on the bottom portion of the tray where the cables are supported. It was judged to be seisimicallyadequate since the warping does not impact the overall structuralintegrity or siesmic response of the cable tray. See picture 2.

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.

I. Does anchorage of equipment in the area appear to be free of YZ NQ UE' N/AF potentially adverse seismic .conditions (if visible without necessarily opening cabinets)?

A steel base plate for a column conduit supportnear airlock2R106 has two anchors with nuts not fully tightened (see photograph 1). There is approximatelya 1/8" gap between the bottom of the nuts and the top of the plate. Deflections will increase slightly due to this, though the support is judged to be seismically adequate as the anchors are embedded in the concrete and will resist the tension forces experienced during an event as intended. CR 519997 has been written to resolve this issue.

There is a cantileveredframe supporting a circularduct on the west wall missing an anchorbolt (see photograph 2). The adjacent support has all three anchors though the top and bottom anchors are missing washers. The two anchorspresentallow for the tension/compression action to occur in the event of movement during a seismic event. The duct weight isn't significantoverthe span observed to be supported and the support is judged to be seismically adequate. CR 5.19729 has been written to install the missing anchor and washers.

There is a missing anchoron the south support for 2H21-P008 along the west wall (see photograph3). It is judged to be seismically adequate as the two anchorsprovide enough strength to resist overturning of the equipment during a seismic event. CR 519996 has been written to reinstall the missing anchor.

2. Does anchorage of equipment in the area appear to be free of significant YO NEI U0 N/AO degraded conditions?
3. Based on. a visual inspection from the floor, do the cable/conduit Y2I NEI UU N/AU1 raceways and HVAC ducting appear to be free of potentially adverse seismic conditions (e.g., condition of supports is adequate and fill conditions of cable traysý appear to be inside acceptable limits)?
4. Does it appear that the area is free of potentially adverse seismic spatial Y9 NEI UU N/AU-interactions with other equipment in the area (e.g., ceiling tiles and lighting)?'

1 If the room in which the SWEL item is located is very large:(e~g., Turbine Hall), the area selected should be described.

This selected area should be based on judgment, e.g., on the order of about 35 feet from the SWEL item.

7. Does it appear that the area is free of potentially adverse seismic YZ NEO UE] N/AE]

interactions associated with housekeeping practices, storage of portable equipment, and temporary installations (e.g., scaffolding, lead shielding)?

There is a pair of loose pliers underneath2H21-P008 along the west wall (seephotograph,3). This is not a seismic concern. CR 519996 has been written to remove the pliers.

8. Have you looked for and found no other seismic conditions that could YZ NE] UE]

adversely affect the safety functions of the equipment in the area?

There is a missing bolt on the east side of the large enclosure that houses both 2H21-P173 and 2C82-P001 (see photograph4). There are enough bolts present to provide enough strength to keep the enclosure together during a seismic event. It is judged to be seismically adequate.

Additional space is provided at the end of this checklist for-documenting other comments..

1. Does anchorage of equipment in the area appear to be free of YN NEI U- N/AU potentially adverse seismic conditions (if visible without necessarily opening cabinets)?
2. Does anchorage of equipment in the area appear to be free of significant Y10 NO U- N/AU degraded conditions?
3. Based on a visual inspection from the floor, do the cable/conduit YE NEI UU N/AU raceways and HVAC ducting appear to be free of potentially adverse seismic conditions (e.g., condition of supports is adequate and fill conditions of cable trays appear to be inside acceptable limits)?
4. Does it appear that the area is free of potentially adverse seismic spatial. YI NEI U- N/AU interactions with other equipment, in the area (e.g., ceiling tiles and lighting)?

The lights in the vicinity have hooks which are not fully closed.

However, they have lock plugs which:will prevent the fall of these lights, Therefore, they arejudged as seismically adequate. However, a CR has been initiated to provide ties to restrainthe lights better (CR513069).

IIf the room in which the SWEL item is located is very large (e.g., Turbine Hall), the area selected should be described.

This selected, area should be based on judgment, e.g., on the order of about 35 feet from the SWEL item.

There is evidence of a'water leak behindseveral of the baseplates on the wall at R14. There is some mild corrosionof the bolts and base plates due to the leak, but the rust stains on the walls indicate that the corrosion ismild. Since oxidation is only on the surface, the anchors are not degraded.Therefore, the anchors arejudged not be a seismic concern.

3. Based on a visual inspection from the floor, do the cable/conduit Y0 NE UE3 N/AEI raceways and HVAC ducting appear to be free of potentially adverse seismic conditions (e.g., condition. of supports is adequate and fill conditions of cable trays appear to be inside acceptable limits)?

4., Does it appear that the area is free of potentially adverse seismic spatial YZ NE] UEl N/AE]

interactions with other equipment in the area (e~g., ceiling tiles and lighting)?

The suspended light above safety-relatedAOV 2G41-F054 on the 203' elevation of the Unit 2 Reactor Building is hung with an open hook and is not safety-wired to the supportingsteel. Duringa seismic event, it is possible that the light will become dislodgedfrom the hook. The light is powered with a twist lock connection, which will restrainthe light in the event ofafall. Therefore, it isjudged to not be a potentially adverse seismic condition.

There is afour bolt base plate vertical supportfor a small bore air supply pipe runningto 2E51-F003 that is missing one anchor bolt on the 87' elevation in Bay 10 of the Torus Room. This support is approximately2 feet off thefloor and it supports the end,of the rigid pipe. The remainingportionof this system is flex hose to 2EB51-F003 (See Figure 2). There is a similarsupport a short distance away-that is

'intact.The pipe is well supportedon the wall by its attachment to2P52-A 001. The supportdoes not carrya large load andat this elevation would not see a significantseismic acceleration.Therefore, the SWE's have determinedthat the, base-plate configuration is seismically acceptable. This bolt does not need to be installed.
