1. IN A FUEL ELEMENT ASSEMBLY ADAPTED TO BE RIGIDLY SUPPORTED WITHIN THE CORE OF A SUPERHEAT BOILING WATER REACTOR, THE COMBINATION COMPRISING AN OUTER CONTAINMENT TUBE ADAPTED FOR FORCED INTRODUCTION OF PRIMARY COOLANT INTO ONE END THEREOF AND FOR DISCHARGE OF SAID COOLANT FROM THE OTHER END THEREOF INTO A HEAT EXCHANGER MEANS EXTERIOR OF SAID FUEL ASSEMBLY, SAID OUTER CONTAINMENT TUBE COMPOSED OF A CONSTRUCTION MATERIAL HAVING A LOW THERMAL NEUTRON CROSS SECTION FOR CIRCULATION OF A PRIMARY COOLANT THEREIN, A FIRST CONCENTRIC INNER TUBE HAVING A CLOSED BOTTOM RIGIDLY SUPPORTED WITHIN SAID OUTER TUBE, A SECOND CONCENTRIC INNER TUBE RIGIDLY DISPOSED WITHIN SAID FIRST CONCENTRIC INNER TUBE, SAID SECOND INNER TUBE ENDING IN SPACED RELATION FROM THE BOTTOM OF SAID FIRST INNER TUBE AND EXTEDNING FROM THE TOP OF SAID FIRST INNER TUBE, SAID SECOND INNER TUBE BEING OPEN AT THE BOTTOM, SAID FIRST CONCENTRIC INNER TUBE ADAPTED TO RECEIVE WET STEAM FROM SAID EXCHANGER AT THE OPEN END THEREOF AND SAID SECOND CONCENTRIC INNER TUBE ADAPTED FRO THE DISCHARGE OF SUPERHEATED STEAM AT THE END THEREOF WHICH IS NOT IN SPACED RELATION FROM THE BOTTOM OF SAID FIRST INNER TUBE, INSULATING LINER MEANS SUPPORTED RIGIDLY WITHIN SAID FIRST CONCENTRIC INNER TUBE IN SPACED RELATION THEREWITH, SAID FIRST AND SECOND INNER CONCENTRIC TUBES AND SAID LINER BEING CONSTRUCTED OF MATERIALS HAVING HIGH STRUCTURAL STRENGTH AT HIGH TEMPERATURES AND AT LEAST MODERATELY LOW THERMAL NEUTRON CROSS SECTIONS, A FIRST QUANTITY OF FISSILE FUEL UNIFORMLY SUPPORTED AROUND AND ALONG THE ANNULUS BETWEEN SAID INNER AND OUTER TUBES, AND A SECOND QUANTITY OF FISSILE FUEL UNIFORMLY SUPPORTED AROUND AND ALONG THE ANNULUS BETWEEN SAID LINER AND SECOND INNER TUBE.
2. IN A FUEL ELEMENT ASSEMBLY IN COMBINATION WITH REACTOR STRUCTURE AND ADAPTED TO BE RIGIDLY SUPPORTED BY GRID PLATES WITHIN THE CORE OF A SUPERHEAT BOILING WATER REACTOR, THE COMBINATION COMPRISING A VERTICALLY ORIENTATED OUTER CONTAINMENT TUBE OPEN AT THE BOTTOM AND TOP THEREOF, SAID OUTER CONTAINMENT TUBE BEING COMPOSED A CONSTRUCTION MATERIAL HAVING A LOW THERMAL NEUT CROSS SECTION, FIRST AND SECOND CONCENTRIC INNER TUBES RIGIDLY SUPPORTED WITHIN SAID OUTER TUBES, SAID SECOND TUBE BEING DISPOSED WITHIN SAID FIRST INNER CONCENTRIC TUBE, SAID FIRST CONCENTRIC INNER TUBE HAVING A CLOSED BOTTOM AND SAID SECOND CONCENTRIC INNER TUBE ENDING IN SPACED RELATION WITH SAID BOTTOM, ONE OF SAID INNER CONCENTRIC TUBES BEING ADAPTED TO RECEIVE FLUID DISCHARGED FROM THE OPEN TOP OF SAID OUTER CONTAINMENT TUBE, TRANSMISSION MEANS CONNECTED TO THE TOP OF THE OTHER INNER CONCENTRIC TUBE FOR WITHDRAWING SUPERHEATED STEAM THEREFROM, METALLIC INSULATING LINER MEANS SUPPORTED RIGIDLY IN SPACED RELATION WITHIN SAID FIRST CONCENTRIC INNER TUBE TO CREATE AN AREA OF LOW THERMAL CONDUCTIVITY BETWEEN SAID INSULATING LINER MEANS AND SAID FIRST INNER TUBE, THEREBY LIMITING THE RADIAL FLOW OF HEAT THROUGH SAID AREA, SAID FIRST AND SECOND CONCENTRIC INNER TUBES AND SAID LINER MEANS BEING CONSTRUCTED OF MATERIALS HAVING HIGH STRUCTURAL STRENGTH AT HIGH TEMPERATURES AND AT LEAST MODERATELY LOW THERMAL NEUTRON CROSS SECTIONS, A FIRST QUANTITY OF FISSILE FUEL MATERIAL UNIFORMLY SUPPORTED AROUND AND ALONG THE ANNULUS BETWEEN SAID INNER AND OUTER TUBES, AND A SECOND QUANTITY OF FISSILE FUEL UNIFORMLY SUPPORTED AROUND AND ALONG THE ANNULUS BETWEEN SAID LINER AND SECOND INNER CONCENTRIC TUBES.
