Claim 1
Independent Claim
140 words
A NUCLEAR REACTOR COMPRISING A VERTICAL, CYLINDRICAL PRESSURE VESSEL, A HORIZONTAL FLOW DISTRIBUTOR EXTENDING ACROSS SAID VESSEL, A PLURALITY OF VERTICALLY DISPOSED FUEL ELEMENTS FORMED OF URANIUM DIOXIDE CENTRALLY LOCATED IN SAID PRESSURE VESSEL AND SPACED THEREFROM ABOVE SAID FLOW DISTRIBUTOR, A MASS OF GRAPHITE PARTICLES OF ABOUT 100 MESH SIZE DISPOSED IN SAID PRESSURE VESSEL ABOVE SAID FLOW DISTRIBUTOR, VARIABLE PUMPING MEANS FOR FORCING HELIUM INTO THE PRESSURE VESSEL BELOW THE FLOW DISTRIBUTOR SO THAT THE HELIUM RISES THROUGH THE GRAPHITE PARTICLES TO ESTABLISH AND MAINTAIN A FLUIDIZED BED THEREOF, A WATER INLET HEADER DISPOSED NEAR THE BOTTOM OF SAID FLUIDIZED BED, A WATER OUTLET HEADER DISPOSED NEAR THE TOP OF SAID FLUIDIZED BED, VERTICAL COOLANT TUBES LOCATED IN THE SPACE BETWEEN THE FUEL ELEMENTS AND THE PRESSURE VESSEL EXTENDING BETWEEN SAID HEADERS, AND MEANS FOR FLOWING WATER THERETHROUGH.
