Engineering Report No. GGNS-CS-12-00002 Rev. 0 Attachment D Page 2 of 167 Status: YZ NE-UF-1 Area Walk-By Checklist (AWC)

AWC- 001 Location: Bldg. AB Floor El. 93 Room, Area' 1A 102,07 SWEL Components: SWELl- 024,030 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 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?

All anchor bolts from visually inspection seem to be in intact. The supports were coated and some mild oxidation/dirt was noticed on some anchor supports in the room but were no concerns to the anchors as they can still perform as designed.

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

Temporary scaffold was identified in this area but did not create any seismic interaction issues. 18' line off RHR Heat exchanger A has a base plate that is not welded to embed plate for the support. The pipe support is for horizontal load of the pipe and allows the pipe to move in the vertical direction.

Bent pipe support base plate CR-GGN-2012-11343.

Comments Temporary scaffold was identified in the area along with temporary extension cords and lighting in the area. There is stored scaffolds in the safe storage area and the temporary scaffold is seismically restrained in the area. The temporary lighting has flexibility so that seismic interaction will not be an issue. Broken conduit support conduit has adequate clearance from any safety related equipment and therefore is free of any potentially adverse seismic interactions CR-GGN-2012-12206.

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

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

There are wires attached to displacement transducers but the wires are covered, protected and not exposed to the environment, therefore would not create a fire hazard. The wires are flexible and will not create a seismic interaction issue.

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

Long term scaffolding <2' away from valve. Scaffold was evaluated per the attached tag. Scaffold is also restrained in both N-S and E-W directions, and therefore does not cause an adverse seismic condition.

Tube steel members supporting conduits running to the P1 1-F064 and P11-F065 shows surface corrosion. The corrosion was visually inspected and determined to be limited in extent and depth. Therefore, it is judged to have negligible affects on the ability of the affected components. See photo.

AB Floor El. 139 Room, Area' IA304, 07 SWEL Components: SWELl- 015 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 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?

Surface corrosion has been observed on many items (pipe, pipe support members, baseplate, hardware, etc.). The corrosion was visually inspected and determined to be limited in extent and depth.

Therefore, it is judged to have negligible affects on the ability of the affected components. See photos.

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