. .I 15737-2-G03-107 3183-017 equipment in this area will be pre-packaged to. ensure smearable surface..

activity does not exceed the limits for unrestricted release. No packages will be opened in this area.

2.2.4.12 Swipe Test Area This is an area of low background radiation provided for taking radiation surveys of the containers and for counting the activity of smears.

2.2.4.13 Fork Lift Battery Charging Area This area is provided for charging the batteries of the fork lifts. ~ It '

will also be used by personnel who will view operations in the compactible ,

trash packaging area through the window in the wall separating the two areas.

2.2.4.14 High Radiation Staging Area This area is provided as a staging area for containers with contact dose rates in excess of 100 mrem /hr.

2.3 Major Systems 2.3.1 Heating , Ventilating and Cooling (HVAC) 2.3.1.1 Design Basis The W WF HVAC System will:

a. Maintain a negative pressure with respect to ambient conditions within the contaminated areas of the WWF by exhausting more air than is supplied and filtering the air being exhausted in order to limit the quantity of airborne contaminants released to the environment.

The HVAC system design assumes that the greatest airborne radioactivity within the W WF is in the Disassembly and Sectioning Area and in the Decontamination Area. Therefore, the HVAC system design provides a minimum differential pressure in these areas of

-0.125" water gauge with respect to atmosphere,

b. Direct air flow from areas of lower contamination toward areas of higher contamination,
c. Maintain a winter temperature of 700F and a summer temperature of 75oF in the WWF for outdoor design temperatures of Summer 94oFDB 750FWB Winter 7oF except in the receiving and shipping area and in the shipment room.

These areas will have winter heating and forced or natural ventilation for summer cooling. The design temperatures area:
