Abstract

An automatic vent system can be used, for example, in a contaminant 28 of a nuclear reactor so that when pressure in the contaminant rises as a result of an accident, gas and contaminant (particles) pass into inertial separators 17 in a chamber 18 into where contaminant is separated and exhausted within the contaminant from chamber 18 by a pump impeller 26, while clean gas passing from the separators into a duct 12 drives a turbine 24 to power the impeller 26. The system requires no external power source and can thus remain dormant until an emergency occurs and then provide high extraction of contaminant with minimum pressure drop with maximum extraction of contaminants. Coalescer/mist eliminators 30, 31 may be located upstream and/or downstream of separators 17. In an alternative arrangement, the pump impeller (or other pump) can be driven from an external power source.
