Claim 1
Independent Claim
128 words
THE METHOD OF OPERATING A HETEROGENEOUS NUCLEAR REATOR COMPRISING A CORE CONTAINING A PLURALITY OF FUSSIONABLE MATERIAL-BEARING FUEL ELEMENTS ARRANGED TO HAVE A POSITIVE COOLANT DENSITY COEFFICIENT OF REACTIVITY AND HAVING AN OPERATING NEUTRON SPECTRUM ENERGY LEVEL SUBSTANTIALLY ABOVE THE THERMAL NEUTRON LEVEL, SAID FUEL ELEMENTS BEING ARRANGED IN A FIXED LATTICE IN SAID CORE, SAID CORE HAVING A PLURALITY OF FIXED REGULAR FLOW CHANNELS THERETHROUGH, AND A NEUTRON REFLECTOR DISPOSED ABOUT SAID CORE, SAID METHOD COMPRISING THE STEPS OF EFFECTING REACTOR CRITICALITY BY INTRODUCING INTO SAID CORE A SINGLE PHASE HYDROGENISOTOPE CONTAINING FLUID CAPABLE OF A SUBSTANTIAL CHANGE IN DENSITY WITH A CHANGE IN HEAT CONTENT, CIRCULATING SAID FLUID THROUGH SAID FIXED REGULAR GLOW CHANNELS IN SAID CORE WHILE MAINTAINING SAID FLUID IN A SINGLE PHASE THROUGH-
