Thermionic fuel rod with nuclear fuel
Abstract
Abstract THIS INVENTION RELATES TO THERMIONIC FUEL ELEMENTS, PROVIDED WITH NUCLEAR FUEL, FOR DIRECT CONVERSION INTO ELECTRICAL ENERGY OF HEAT PRODUCED BY NUCLEAR FISSION. THE THERMIONIC ELEMENTS COMPRISE TUBULAR, CONCENTRICALLY POSITIONED EMITTERS (1) THE COLLECTORS (4). THE FUEL ELEMENTS ARE ELECTRICALLY CONNECTED IN SERIES AND ARE PROVIDED WITH RESPECTIVE DISCHARGE CHAMBERS (5) WHICH ARE SEPARATED FROM EACH OTHER BY NOVEL VACUUM-TIGHT SEALS, THE SEALS PROVIDING A MECHANICAL AND ELECTRICAL SEPARTION OF THE RESPECTIVE THERMIONIC ELEMENTS. THE DISCHARGE CHAMBER, PROFICED AT ONE END OF EACH THERMIONIC ELEMENT, IS FILLED WITH CESIUM VAPOR. THE NOVEL SEAL COMPRISES A DISCSHAPED RIGID METAL-CERAMIC COMPONENT (6,7) AT ONE END, AND A PLIABLE OR YIELDABLE METAL-CERAMIC PORTION ACTING AS A GUIDE RING (10,11) AT THE OTHER END, ACTING IN COMBINATION WITH A VACUUM-TIGHT PLATE (9).
