PURPOSE: A pressure container cooling device is provided to cool a core and a pressure container by controlling the flow of coolants through a connection part. CONSTITUTION: A core support barrel(110) includes a core and a reflector which surrounds the core. A reactor pressure container(120) surrounds the outer side of a core support barrel and forms a coolant path. A coolant inlet is formed on one side of the pressure container to supply the coolant to the core support barrel. A rising path(170) provides a coolant path by connecting an upper core part to a lower core part. The coolant passing through the upper core part to the core is discharged through a coolant outlet. A connection part passes through the coolant path and the lower core part.
