Location (Bldg, Elev, Room/Area): Area 40 - AB2, 633, 9 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 of judgments 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 Yes potentially adverse seismic conditions (if visible without necessarily opening cabinets)?

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

3. Based on a visual inspection from the floor, do the cable/conduit Yes 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 Yes spatial interactions with other equipment in the area (e.g., ceiling tiles and lighting)?

5. Does it appear that the area is free of potentially adverse seismic Yes interactions that could cause flooding or spray in the area?

6. Does it appear that the area is free of potentially adverse seismic Yes interactions that could cause a fire in the area?

7. Does it appear that the area is free of potentially adverse seismic Yes interactions associated with housekeeping practices, storage of portable equipment, and temporary installations (e.g., scaffolding, lead shieldinq)?

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 YZ NEi UE' N/AE potentially adverse seismic conditions (if visible without necessarily opening cabinets)?

Facing Containment,the lower left bolt on the lower left brace below 1-CPN-38, does not have full thread engagement (1 threadshy of full engagement). PerDC-D-3053S-430, only 50%

threadengagement is requiredfor full tensile capacity of concrete anchorbolts. Therefore the brace is seismically adequate. - AR 2013-4499 was issued Bolt is backed out of 1-CPN-38, however there is full thread engagement and the nut is tack welded in place - AR 2013-4500 was issued

2. Does anchorage of equipment in the area appear to be free of significant YN NE] UE- N/AE degraded conditions?

3. Based on a visual inspection from the floor, do the cable/conduit YE NE UE- 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 NE UE 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.

Plan for Future Seismic Walkdown of Inaccessible Equipment Due to the completion of the DCCNP1 outage walkdown, all equipment included on the DCCNP1 SWELl and SWEL2 have been completed. There are 16 items that have been deferred in DCCNP2. Six of these items were located in Containment inside the Shield Wall and could not be included in the walkdown when the units were at power. There were nine electrical equipment items that could not be opened during the walkdown due to safety reasons.

The remaining item was in an enclosure that also could not be opened for safety reasons in the Auxiliary Building. The electrical equipment items will be inspected at the next service outage for this equipment. The items in Containment and the item in the enclosure in Auxiliary Building will be inspected during the Unit 2 Outage in Fall 2013. Table E-1 summarizes the reasons each item is inaccessible during normal plant operation.

The Area Walk-Bys associated with the items in Containment will be performed concurrently with the component walkdowns. Area Walk-Bys in accessible areas of the plant were performed and are included in this report revision that includes areas containing electrical equipment not accessible for internal inspection.
