Means for supporting fissile material in a nuclear reactor

Abstract

Abstract ZONTAL GRID STRUCTURE. THE TUBES ARE SECURED IN THE GRID STRUCTURE AND MATE THEREWITH AT THEIR UPPER ENDS. A NUCLEAR POWDER FAST REACTOR SYSTEM IS DESCRIBED WHICH UTILIZES GAS AS A COOLANT. THE REACTOR SYSTEM INCLUDES A PRESTRESSED CONCRETE CONTAINMENT VESSEL WHICH CONTAINS THE ENTIRE PRIMARY SYSTEM OF THE REACTOR, COMPRISING THE CORE, CONTROL ROD DRIVE MECHANISMS, COOLANT CIRCULATORS, STEAM GENERATORS AND ASSOCIATED MAIN COOLANT DUCTING. THE INTERIOR OF THE VESSEL IS SEPARATED INTO TWO REGIONS, THE LOWER ONE CONTAINING THE CORE AND HAVING PROVISION FOR EXPLOSION ABSORPTION AND WATER FLOODING. THE CORE IS COMPRISED OF FUEL ELEMENTS SUPPORTED IN A PLURALITY OF ELONGRATED TUBES WHICH DEPEND FREELY FROM A GENERALLY HORI-
