QUANTIFYING THE EFFECTS OF BREAK SOURCE FLOW RATES ON AP600 CONTAINMENT STRATIFICATION

摘要

The Westinghouse AP600 containment structure is a steel containment vessel surrounded by a thick concrete shield building. A passive containment cooling system ap- plies gravity-drained water to the outer surface of the steel containment shell to remove heat by evaporation and convection. Mass transfer is the dominant means of containment heat removal on both inner and outer steel shell surfaces.
