Summary of the Internal Pressure Capacity of Prestress Concrete Containment Vessel (PCCV)

The nuclear containment acts as the final barrier against the release of radioactivity. Hence, its design, strict performance and safety evaluation under severe conditions are of great significance, whether through experiments or by numerical methods. In particular, the behavior prediction from functional to structural failure when the internal pressure is higher than the design pressure (Pd) is very important in terms of structural safety.
