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 potentially adverse seismic conditions (if visible without necessarily opening cabinets)?
2. Does anchorage of equipment in the area appear to be free of significant degraded conditions?
3. Based on a visual inspection from the floor, do the cable/conduit 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 support for a conduit feeding cable to lights in Bay 1 which is not attached to the conduit (see photograph 1). The southern end of the conduit is not screwed into the condulet which continues to the light (see photograph 2). The weight of the conduit is small and will not cut the cable under its self weight and vertical seismic accelerations are low at this elevation. However, the conduit support should 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 photographs 3 and 4). The conduit is resting on the support intended to only support the 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 unsupported for approximately 25 feet. The conduit is judged to provide adequate protection 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 interactions with other equipment in the area (e.g., ceiling tiles and lighting)?

There are three Unistrut supports for a conduit attached to the IE1I1-F068B RHR Heat Exchanger Discharge Valve that are ihstalledwith an anchor bolt at the top of the support and no other anchors. The supported conduit is light and the supports are only designed to resist vertical loads. The existing anchor bolt is capable of resisting the tension and bending loads on the supports from gravity loads. The vertical seismic loads' at this, elevation will not exceed 1.0, so upwards vertical loads willnot experienced by the supports. It appears that the supports are installed as designed and that the design is adequate.

Therefore, there is no potentially adverse seismic condition.

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

A wall channel column appears to be missing one anchor.

There are no conduits attached to the channel, and it is well, supported There are numerous additional anchors and the channel is tied into the floor 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 degraded conditions?
3. Based on a visual inspection from-the floor, do the cable/conduit 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.

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

Base plates for Unistrut conduit support along north wall of Room C-114 have holes drilled for 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 the floorare judged to be sufficient for~seismic restraint (see Figures 4, 5 and 6).

2. Does anchorage of equipment in the area appear to be free of significant degraded conditions?

A small step ladder was discovered in Room C-114 between Battery Chargers 1R42-SO26 and 1R42-S027 (see Figure 1)., The unrestrained ladder was leaning against one of the battery chargers and has the potential to impact both pieces of equipment during a seismic event. A hand cart was discovered in Room C-114 behind Switchgear 1R22-S016. The cart was restrained to a vertical conduit with a flimsy piece of rope, but the wheels were not chocked (see Figures 2 and 3). During a seismic event, the cart has the potential to roll and rotate around the restraint point, allowing the cart corner to impact the switchgear. In addition, several pieces 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

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

There is a cable tray support immediately adjacent to the wall penetration that is in good condition. The frame is abandoned in place and is not supporting any load. The remaining two bolts are judged adequate to support the small loads on the abandoned frame from its own dead weight, so there is no potentially adverse seismic condition.

In the Unit 2 Control Building above Battery Charger 1R42-S052, there is a nylon rope tied to a pair of conduits that appears to have been abandoned (See CR 524313). The rope is tied off above the conduits to a support that is not visible from thefloor. The conduits are both attached to the wall immediately adjacent to the tie-off location, so the rope is not being used for support. The rope is small and light, and is not free to swing, so there is no potentially adverse seismic condition.
