Keywords:PCV venting, Exhaust gas flow rate, Aerosol deposition in pipe, Scrubber tank water level, MAAP5.04

The FCVS model has been developed using MAAP5.04 with combination of compartment-junction-heat sink. This model enables to estimate detail transient bahavior of PCV vent exhaust gas for several accident scenarios.
