Steam generating plant

Claim 1

A STEAM GENERATING PLANT COMPRISING A PRIMARY COOLANT CIRCUIT AND A SECONDARY COOLANT CIRCUIT, A NUCLEAR REACTOR AND A FIRST HEAT EXCHANGER POSITIONED IN SAID PRIMARY COOLANT CIRCUIT, A LIQUID ALKALI METAL PRIMARY COOLANT OPERATING AT SUPERATMOSPHERIC PRESSURE CIRCULATING THROUGH SAID PRIMARY COOLANT CIRCUIT ABSORBING HEAT WITHIN SAID NUCLEAR REACTOR AND RELEASING HEAT WITHIN SAID FIRST HEAT EXCHANGER, A SECOND HEAT EXCHANGER AND SAID FIRST HEAT EXCHANGER POSITIONED IN SAID SECONDARY COOLANT CIRCUIT, TUBULAR VAPOR GENERATING SURFACES DISPOSED WITHIN SAID SECOND HEAT EXCHANGER, AN ELASTIC FLUID SECONDARY COOLANT CONTAINING A SUSPENSION OF PARTICLES OF SOLID MATERIAL CIRCULATING THROUGH SAID SECONDARY COOLANT CIRCUIT ABSORBING HEAT FROM SAID PRIMARY COOLANT WITHIN SAID FIRST HEAT EXCHANGER AND GIVING UP HEAT WITHIN SAID SECOND HEAT SURFACES, SAID SECONDARY COOLANT OPERATING AT A SUPERATMOSPHERIC PRESSURE WHICH IS LESS THAN THAT OF THE PRESSURE OF THE PRIMARUY COOLANT, A VAPORIZABLE LIQUID CIRCULATING THROUGH SAID TUBULAR VAPOR GENERATING SURFACES IN SAID SECOND HEAT EXCHANGER TO RECEIVE HEAT FROM SAID SECONDARY COLLANT AND TO BE VAPORIZED IN THE COURSE OF ITS FLOW THROUGH SAID SECOND HEAT EXCHANGER, SAID VAPORIZABLE LIQUID OPERATING AT A VAPOR PRESSURE IN SAID HEAT EXCHANGER WHICH IS GREATER THAN THE PRESSURE OF SAID SECONDARY COOLANT, WHEREBY THE PARTICLES OF SOLID MATERIAL IN THE ELASTIC FLUID SECONDARY COOLANT ARE ADAPTED TO CONVEY HEAT FROM SAID FIRST HEAT EXCHANGER TO SAID SECOND HEAT EXCHANGER AND THE ELASTIC FLUID AND THE SOLID MATERIAL THEREIN ARE INERT TO FLUID INADVERTENTLY LEAKING INTO THE SECONDARY COOLANT CIRCUIT IN THE FIRST AND SECOND HEAT EXCHANGERS.
