Abstract: An improvement to an SFR reactor of the integrated type wherein each of the outlet windows of the intermediate exchangers is surrounded in an enclosure in fluid communication with a pipe shaped into a toroid; and each of the inlets of the pump group which pumps the sodium from the hot area to the cold area through the intermediate exchangers is also in fluid communication with the toroid, such that the primary sodium originating from the hot area and exiting from the intermediate exchangers flows through the toroid and is then directed to the cold area by the said pump group.

Abstract: The invention relates to a novel architecture for a nuclear reactor of the integrated type.

Abstract: A compact pressurised water nuclear reactor comprises a primary circuit fully integrated into the reactor vessel (10). Thus, a single steam generator (12) forms the cover of the vessel (10) and the pressuriser (30) and the primary pumps (28) are housed in the vessel (10). The same is true for the control mechanisms of the control rods (40). Finally, a venturi system (44) is also provided in the vessel (10) to create water circulation if there is a failure of the primary pumps (28).

Abstract: A method for controlling heat exchange in a nuclear reactor. The reactor contains at least one thermal valve, at least one heat exchanger having a coolant flowing therein, with the heat exchanger being immersed in a pool containing a fluid. The heat exchanger is confined by a container having an upper part with an opening therein and a lower part having means for introducing the fluid through such lower part as well as means for partially or totally opening or closing said opening in the upper part and means for partially or totally opening or closing opening in the lower part. The method comprises the steps of closing the opening in the upper part of the container to thereby vaporize said fluid, in order to cause a cessation of heat exchange between the coolant and the fluid; and opening the opening in the upper part of the container to thereby cause the fluid to be heated and to rise by convection, thereby permitting heat exchange to occur between the coolant and the fluid.

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.

Abstract: Internal condenser system for discharging vapor from a circuit into a tank or pool to reduce pressure in said circuit.The internal condensation conduit (47) comprises a diaphragm (52) just upstream of a cold liquid feed orifice (55); the jet of vapor passing through orifice (53) of the diaphragm creates a zone of significantly negative pressure around this jet and downstream of the diaphragm causing cold liquid to be sucked up. This causes the vapor to condense in the mixing chamber (56).One possible application relates to primary circuits of a nuclear reactor.
