Emplacement ventilation system
This analysis updates design concepts for emplacement ventilation based upon the increased air flow required through the drift in the EDA II design (CRWMS M and O 1999a, Table O-6) and by current thermal modeling results compared to the VA design (DOE 1998, Section 4.2.4). It reviews the air pathway in the emplacement drift, describes three exhaust system options, discusses two air control options, and examines concepts for several system physical components including isolation doors, a portable shadow shield, and a partition in an exhaust main. The air path through the emplacement drift, itself, remains the same as described in the VA and EDA II design; that is, exhaust fans located on the surface pull air through an intake shaft into the subsurface repository. The ventilation air is distributed to the east and west mains by the cross-block drifts. From the mains, the air enters the emplacement drifts and flows to a central exhaust raise. The air then travels down an exhaust raise to the exhaust system.
