Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
126 words
A COMPOSITE CORE FOR A NUCLEAR REACTOR, WHICH COMPRISES: (A) AN INNER FAST CORE CONTAINING FISSIONABLE MATERIAL, SAID FAST CORE BEING SUBCRITICAL BY ITSELF; (B) A LAYER OF MATERIAL SEMI-PERMEABLE TO THE PASSAGE OF NEUTRONS THERETHROUGH, SAID SEMI-PERMEABLE LAYER SURROUNDING THE EXTERIOR OF SAID FAST CORE; (C) A GRAPHITE REFLECTOR SURROUNDING THE EXTERIOR OF SAID SEMI-PERMEABLE LAYER; AND, (D) AN ANNUALAR THERMAL CORE SURROUNDING THE EXTERIOR OF SAID GRAPHITE REFLECTOR, SAID THERMAL CORE CONTAINING FISSIONALBE MATERIAL AND A MODERATOR MATERIAL, SAID THERMAL CORE BEING SUBCRITICAL BY ITSELF AND COOPERATING WITH SAID SUBCRITICAL FAST CORE TO FORM A CRITICAL COMPOSITE REACTOR CORE WHICH GENERATES A FAST NEUTRON FLUX AND WHEREIN THE TEMPERATURE OF THE FAST CORE IS LIMITED BY THE SHUT-OFF PROPERTIES OF THE ANNULAR THERMAL CORE.
