Abstract (en)
[origin: EP0798469A1] The emergency feed injector (B) for a steam generator (G) is fed by steam from the generator itself, and by pressurised water from an ejector (C). Initially, the ejector is fed by a water circuit (D) that consists of a reservoir (63) pressurised by the steam and an exit pipe (64) with a non-return valve (65). Eventually, the ejector is fed by low pressure water from a reservoir (73) and by high pressure water from a bleed circuit (R) branching off downstream (42) of the injector (B). This arrangement allows water from the low pressure reservoir to be driven into the injector for pressurising to a pressure higher than that of the steam.
