4. Does it appear that the area is free of potentially adverse seismic spatial x

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

Block wall SB1-6, SB I-7, and SB I-8 are adequate under calculations DSC-0085, DSC-0086 and DSC-0087, respectively. Block wall SB1-9 adequate under calculation DSC-0088. These calculations are part of a follow-up seismic analysis in support of lE80-11 calculations.

Shower in area judged rugged and not a spray hazard.

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

Fire signs posted on battery room door. Batteries are well restrained and no potential interaction or falling of objects that could short the battery terminals and cause afire were found. Judged adequate.

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)?

Potential falling from severalfire extinguishers in area is judged not a concern.

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

A damagedpipe insulation near valve MOV-IMS-105 was judged to be due to servicing of the valve and not a seismic concern. A pipe connected to a containment penetration 89 (valve TV-ISV-I OOA is on this pipe) has a gap of 1/8" to a knee brace mounted on Safeguards Building. The effect of differential building displacements at this elevation between the two buildings was investigated andfound that the pipe has adequate flexibility to accommodate the demand seismic displacements of the two buildings.

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 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)?

Several potential seismic interactions found (see Photos), all judged not significant, except one. Temporary bullet shield placed by Security poses risk to adjacent Pressure Transmitter. CR-2012-14020 was generated A follow-up walkdown showed the barrier moved and properly secured

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

Several sources of minor corrosion in room (see photos). Only two instances were signi/icant. CR-2012-13970 and CR-2012-13971 were generated to address corrosion on Component TV-ICC-I 1OF2 and Valve IA C-1150, respectively. Both valves are currently operable. Minor cracking on the east wall was judged as surface cracking and not significant.
