ABSTRACT:
A pressure release arrangement for a pressure container such as a safety containment of a nuclear reactor, wherein a pressure release pipe extends through the containment walls and is closed at its inner end and connected to a drawbar mounted with its other end to a distant point of the container wall. The release pipe has within the containment an area of reduced thickness providing for a design breaking point at which the pipe is caused to rupture when the container is stretched by overpressurization beyond a predetermined point thereby relieving the pressure.
With this arrangement, pressure is safely relieved before uncontrolled explosion of the containment but only when absolutely necessary.
