Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
131 words
THE METHOD OF OPERATING A HETEROGENEOUS NUCLEAR REACTOR HAVING A PLURALITY OF FISSIONABLE MATERIAL-BEARING FUEL ELEMENTS ARRANGED TO UNDERGO A SELF-SUSTANINING FISSIONTYPE CHAIN REACTION, SAID FUEL ELEMENTS BEING ARRANGED IN A FIXED LATTICE AS A CORE, SAID CORE HAAVING A PLURALITY OF FIXED REGULAR FLOW CHANNELS THERETHROUGH, COMPRISING THE STEPS OF SUPPLYING A SINGLE PHASE HYDROGEN-IOSTOPE-BEARING VAPOR WHICH UNDERGOES A CHANGE IN DENSITY WITH A CHANGE IN PRESSURE AND ENTHALPY TO SAID CORE, CIRCULATING SAID VAPOR INDEPENDENTLY OF SAID FUEL ELEMENTS THROUGH SAID FIXED REGULAR FLOW CHANNELS IN SAID CORE IN HEAT TRANSFER RELATIONSHIP WITH SAID FUEL ELEMENTS TO MODERATE SAID CHAIN REACTION WHILE MAINTAINING SAID VAPOR IN A SINGLE PHASE THROUGHOUT SAID CORE, AND REGULATING THE FISSION-TYPE CHAIN REACTION BY CONTROLLABLY VARYING THE DENSITY OF SAID VAPOR IN SAID CORE.
