Abstract：
The determination of design pressure limited value for containment annulus is a key to the ventilation system design for containment annulus. Based on aerodynamics and contaminant transport dynamics, proposes a method to determine the design pressure limited value for the containment annulus under complex environment. Combining with an actual case, explains how to determine the value.
