Neutronic reactor core

Claim 1

AN IMPROVED NEUTRONIC FISSION REACTOR CORE, ADAPTED TO PROVIDE PROPULSIVE POWER BY HEATING GAS FLOWED IN HEAT-TRANSFER RELATIONSHIP THERETHROUGH WHICH COMPRISES: AN AMASSED MULTIPLICITY OF FISSIONABLE-MATERIAL-CONTAINING FUEL ELEMENTS ADAPTED TO ENGAGE WHILE SO AMASSED IN SELFSUSTAINING CHAIN FISSION REACTION WITH CONCOMITANT GENERATION OF HEAT, INTERSPERSED THEREBETWEEN METALLIC STRUCTURE CONSTITUTED OF HOLLOW WALL STRUCTURE WITH A PLURALITY OF SAID HOLLOW WALLS BEING DISPOSED IN THE CONFIGURATION OF A NESTING OG CONCENTRIC, SPACED-APART, CO-EXTENSIVE, OPENENDED CYLINDERS, WHICH CYLINDERS MECHANICALLY CONFINE AND SUPPORT SAID ELEMENTS IN THE CONCENTRIC ANNULI FORMED BETWEEN SAID CYLINDERS AND DEFINE THE PRINCIPAL CONDUIT SYSTEM FOR CONDUCTING SAID GAS IN HEAT-TRANSFER RELATIONSHIP WITH SAID FUEL ELEMENTS, GAS FLOWED THROUGH SAID PRINCIPAL CONDUIT SYSTEM IN HEAT-TRANFER RELATIONSHIP WITH SAID FUEL ELEMENTS CONSTITUTING THE PRINCIPAL COOLANT FOR SAID FUEL ELEMENTS, THERMAL INSULATION INTERPOSED BETWEEN SUBSTANTIALLY THE TOTAL MASS OF SAID METALLIC STRUCTURE DEFINING SAID PRINCIPAL CONDUIT SYSTEM AND SAID FUEL ELEMENTS ALONG WITH SAID GAS, AND, FLOWING WITHIN SAID HOLLOW WALLS, HYDROGENOUS LIQUID THEREBY MAINTAINED IN NEUTRON MODERATION RELATIONSHIP WITH SAID FUEL ELEMENTS AND IN FLOWING, HEAT-TRANFER RELATIONSHIP WITH SAID METALLIC STRUCTURE AND MAINTAINED AT AN OPERATIONG TEMPERATURE SUBSTANTIALLY LOWER THAN THAT OT SAID FUEL ELEMENTS, CONSTITUTING THE PRINCIPAL NEUTRON, MODERANT FOR THE CORE AND THE PRINCIPAL COOLANT FOR SAID INSULATED METALLIC STRUCTURE, AND MEANS FOR CONTINUOUSLY COOLING SAID CIRCULATING HYDROGENOUS LIQUID.
