Abstract
Abstract 1. A PROCESS OF MASSIVELY HYDRIDING A ZIRCONIUM-URANIUM ALLOY FUEL ELEMENT, WHICH COMPRISES SLOWLY HEATING THE ALLOY IN A VACUUM TO A TEMPERATURE ABOVE 1,500*-1,850*F., CONTACTING SAID ALLOY WITH HYDROGEN UNTIL A PRESELECTED H/ZR RATIO IS OBTAINED AT A PRESSURE SUBSTANTIALLY GREATER THAN ATMOSPHERIC, ISOCHORICALLY COOLING THE RESULTING COMPOSITION TO AT LEAST A TEMPERATURE NO HIGHER THAN APPROXIMATELY 1,390*F., AND THEN COOLING SAID COMPOSITION TO AMBIENT CONDITIONS.
