A METHOD OF HYDRIDING SOLID METAL CONTAINING ZIRCONIUM WHICH COMPRISES THE STEPS OF RAISING THE TEMPERATURE OF SAID SOLID METAL DISPOSED WITHIN A CONTROLLED ENVIRONMENT, WHEREIN DELETERIOUS REACTION OF SAID METAL THEREWITH IS AVOIDED, TO A TEMPERATURE OF AT LEAST ABOUT 700*C. AND BELOW THE MELTING POINT OF SAID SOLID METAL, SAID SOLID METAL CONTAINING AT LEAST 50 PERCENT BY WEIGHT OF ZIRCONIUM, HYDRIDING SAID ZIRCONIUM BY MAINTAINING SAID TEMPERATURE WHILE INCREASING THE HYDROGEN CONCENTRATION OF SAID CONTROLLED ENVIRONMENT TO AND MAINTAINING SAID CONCENTRATION AT A HYDROGEN PRESSURE WHICH AT SAID TEMPERATURE PRODUCES A HYDRIDING RATE NOT IN EXCESS OF THAT PRODUCED BY THE DISSOCIATION PRESSURE FOR THE BETA SOLID SOLUTION OF ZIRCONIUM IN A CONTAMINANT-FREE SYSTEM AT SAID TEMPERATURE, AND THEREAFTER COOLING THE FORMED HYDRIDE, WHEREBY ZIRCONIUM HYDRIDE IN SOLID FORM AND
