Summary

Development of metallurgical methods for preparation of U-rich alloys and cermets which are resistant to thermal cycles through the phase transformation as well as to swelling caused by the expansion of fission product gases at high temperatures is described. A technique for cold and hot pressing of complicated shapes suitable for reactor components is described. Development of non-oxide dispersion-type fuel elements is outlined, and a fuel element with good dimensional stability under high temperature, high flux irradiation, consisting of a dispersion of U metal in a high melting point, metallic matrix is described. Developments in non-destructive testing methods are reported. Development of high-UO/sub 2/ ceramic and cermet bodies having physical properties which are well suited to fuel element applications is described. Development of a stable complex carbide for high temperature applications in either an oxidizing or a reducing atmosphere is reported. A spherical UC- graphite fuel element having sufficient strength, impact, and thermal shock resistance for application in the Process Heat Reactor was developed. (W.L.H.)
