Abstract
Abstract THE VISOSITY OR CREEP RESISTANCE OF OXIDE-TYPE REACTOR FUELS MAY BE MINIMIZED BY THE ADDITION OF LOW VISCOSITY MATERIALS WHICH SEGREGATE TO THE FUEL GRAIN BOUNDARIES DURING REACTOR HEAT-UP AND OPERATION. THIS MINIMIZES THE STRESS APPLIED TO THE CLADDING DUE TO MECHANICAL INTERACTION OF THE FUEL AND THE CLAD DURING THE REACTOR OPERATION. SUITABLE MATERIALS INCLUDE GLASS FORMERS WHICH MAY FORM GLASSES WITH THE NUCLEAR FUEL MATERIAL. THE LOW VISCOSITY MATERIAL SEGREGATES TO THE FUEL MATERIAL GRAIN BOUNDARIES RESULTING IN A MARKED INCREASE IN THE CREEP RATE RESULTING FROM LESS RESTRAINED GRAIN BOUNDARY SLIDING.
