Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
138 words
A NUCLEAR REACTOR COMPRISING A CORE CONSISTING OF A MODERATOR MATERIAL SELECTED FROM THE GROUP CONSISTING OF GRAPHITAE AND BERYLLIUM OXIDE, SAID MODERATOR MATERIAL FORMING THE WALLS OF A PLURALITY OF INTERCONNECTED REACTION CHAMBERS AND THE WALLS OF A PLURALITY OF COOLANT DUCTS DISPOSED BETWEEN THE REACTION CHAMBERS, A SUSPENSION OF A FUEL MATERIAL SELECTED FROM THE GROUP CONSISTING OF URANIUM DIOXIDE AND URANIUM CARBIDE IN A GAS WHICH IS NONREACTIVE WITH THE MODATOR MATERIAL AND FUEL MATERIAL IN SAID REACTION CHAMBERS, SAID FUEL MATERIAL HAVING AN AVERAGE PARTICLE SIZE LESS THAN ONE MICRON WHEREBY IT IS MAINTAINED IN SUSPENSION BY THERMAL CONVECTION CURRENTS, MEANS FOR PASSING SAID NONREACTIVE GAS THROUGH THE COOLANT DUCTS AT A PRESSURE GREATER THAN THAT PRESENT IN THE REACTION CHAMBERS, AND AN AUXILIARY SYSTEM FOR FISSION PRODUCT CLEAN-UP CONNECTED TO SAID REACTAION CHAMBERS.
