Purification Area Ventilation

The ventilation system section is comprised of seven subsystems airborne activity confinement system (AACS), central control room habitability (CCRH), Assembly Area ventilation (AAV) system, Disassc ty Area ventilation (DAV) stem. Purification Area ventilation (PAV) system. Building 108-K ventilation (V108) system, and nuscellaneous ventilation tystem. 

The 907 fon and Hs assodated disdiarge danqper and steam coils support planned Purification Area activities. The 907 fiui is the primary ventilation source for transfotmer room 2. 

BuOdtng 105-K rooC induDisassembly Area roof and Purification Area roof will withstand a wind-induced ventilation stack Dure 0.e., the Building 105-K roof will withstand direct and indirect damage from a frilling ventilation stack. The Disassenibty Area roof is too r away to be direct impacted by a Ming ventilation stadc).

Confined-area pollution, where there may be no natural circulation of air and no effective air purification effluent system. This situation is found in factories or mines and inside improperly ventilated garages, service stations, and vehicular tunnels,... 

In practice, in the course of production of fissile materials, permanent sanitary assessments of technological safety, identification of operations to be carried out in working areas according to the degree of hazard as well as sanitary supervision of the working areas and the production environment, ventilation and gas purification systems, working places of the personnel, etc., are obligatory.

Dilution ventilation exposure control methods use an air purification device and returns the exhaust to work area air.
