Area Walk-By Checklist (AWC)

Location: Bldg. REACTOR Floor El. 87 Room, Area' TORUS (BAY 1)

Instructions for Completing Checklist This checklist may be used to document the results of the Area Walk-By near one or more SWEL items. 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.

1. Does anchorage of equipment in the area appear to be free of Y0 N[-] UC] N/AE]

potentially adverse seismic conditions (if visible without necessarily opening cabinets)?

2. Does anchorage of equipment in the area appear to be free of significant YER NEI UE] N/Ar1 degraded conditions?

3. Based on a visual inspection from the floor, do the cable/conduit YEI] N UIE] N/AE]

raceways and HVAC ductingappear 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)?

There is a supportfor a conduit feeding cable to lights in Bay 1 which is not attachedto the conduit (see photograph 1). The southern end of the conduit is not screwed into the condulet which continues to the light (see photograph2). The weight of the conduit is small and will not cut the cable under its self weight and vertical seismic accelerationsare low at this elevation. However, the conduit supportshould be secured to support the conduit and the condult is to be properly attached to ensure long term functionality of the lights. CR 525296 has been written to resolve this issue.

A conduit which starts from the junction box servicing I T48-NOO9A goes to the west wall and continues south. There is one support (CS-25-80) in Bay 1 and another(CS-25-79) on the north end of Bay 16 (just beyond Bay 1) that are not supported by the struts on the wall (see photographs3 and 4). The conduit is resting on the supportintended to only supportthe light (see photograph 5). The weight of the conduit is small and will not adversely affect the support for the light. However, the conduit will move laterally during a seismic event as it is unsupportedfor approximately25 feet. The conduit isjudged to provide adequateprotection to the cable,during impact with the wall.

CR 525303 has been written to support the conduit on the struts as intended.

4. Does it appear that the area is free of potentially adverse seismic spatial YZ NEI UE] N/AE1 interactions with other equipment in the area (e.g., ceiling tiles and lighting)?

1 If the room in whichithe 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 are three Unistrutsupports for a conduit attachedto the IE1I1-F068B RHR Heat Exchanger Discharge Valve that are ihstalledwith an anchorbolt at the top of the support and no other anchors. The supportedconduit is light and the supports are only designed to resist vertical loads. The existing anchorbolt is capable of resisting the tension and bending loads on the supports from gravityloads. The vertical seismic loads'at this,elevation will not exceed 1.0, so upwards verticalloads willnot experienced by the supports. It appearsthat the supports are installedas designed and that the design is adequate.

Therefore, there is no potentially adverse seismic condition.

There is:no sensitive equipment in the vicinity of the pail, and the pipe extends into the pail, providing sliding resistance.

Area Walk-By Checklist (AWC)

Location: Bldg& REACTOR Floor El. 95 Room, Area' SE Diagonal Instructions for Completing Checklist This checklist may be used to document the results of the Area Walk-By near one or more SWEL items. 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 documentingother comments.

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

A wall channel column appearsto be missing one anchor.

There are no conduits attached to the channel, and it is well, supported There are numerous additionalanchors and the channel is tied into thefloor andprovides support to a platform as well. Therefore, it isjudged to be seismically adequate.

2. Does anchorage of equipment in the area appear to be free of significant YZ NO! UEI N/AE degraded conditions?

3. Based on a visual inspection from-the floor, do the cable/conduit YZ NEI U[I N/AE]

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 NEI U1E- N/AE-interactions with other equipment in the area (e.g., ceiling tiles and lighting)?

'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.

A testing rig was discovered tied off to a conduit along the south wall near Instrument 1E21-NOO3A. The rig was chained to a nearby conduit and has a stable base. There are several small valves near the testing rig, but out of the fall zone of the rig. Therefore, it is judged to be seismically adequate.

8. Have you looked for and found no other seismic conditions that could YZ NEI UE-adversely affect the safety functions of the equipment in the area?

Base platesfor Unistrutconduit support along north wall of Room C-114 have holes drilledfor three anchors,but only two are utilized. The Unistrut member and supported conduits are small, so the two anchors in the ceiling and the two anchors in thefloorarejudged to be sufficientfor~seismic restraint(see Figures4, 5 and 6).

A small step ladder was discovered in Room C-114 between Battery Chargers1R42-SO26 and 1R42-S027 (see Figure1)., The unrestrained ladder was leaning againstone of the battery chargersand has the potential to impact both pieces of equipment during a seismic event. A hand cartwas discovered in Room C-114 behind Switchgear 1R22-S016. The cart was restrainedto a vertical conduit with a flimsy piece of rope, but the wheels were not chocked (see Figures2 and 3). During a seismic event, the cart has the potential to roll and rotatearoundthe restraintpoint,allowing the cart cornerto impact the switchgear. In addition, severalpieces of heavy equipment are stored on top of the cart and could be dislodged during,a seismic event, potentially impacting the switchgear (see CR 513335)S

In the Unit 2 ControlBuildingabove Battery Charger1R42-S052, there is a nylon rope tied to a pair of conduits that appearsto have been abandoned(See CR 524313). The rope is tied off above the conduits to a support that is not visiblefrom thefloor. The conduits are both attachedto the wall immediately adjacentto the tie-off location,so the rope is not being usedfor support. The rope is small and light, and is not free to swing, so there is no potentially adverse seismic condition.
