Abstract

The injector (B) designed specifically to supply a steam generator (G) with water at high pressure when necessary, is supplied by steam that may originate from the generator itself, and by pressurized water from an ejector (C) supplied during the start up phase by a water circuit (D) pressurized by steam, and during the steady state phase, by an extraction circuit (R) connected on the downstream side of the injector. This device entrains water originating from a tank at low pressure (73) into injector (B), to pressurize it at a pressure exceeding the steam pressure. Application to safety devices in nuclear power stations.
