DEVELOPMENT OF FERRITIC STAINLESS STEEL-UO$sub 2$ DISPERSION FUEL ELEMENTS
A preliminary definition of a fabrication process for ferritic stainless steel-UO/sub 2/ fuel clad with Type 430 stainiess steel has been achieved. The procedure is an adaptation of an earlier process for preparing austenitic fuel elements, and consists of the cold-binder extrusion of a plastic powder dispersion which is fired in dry hydrogen, fitted with welded end caps, and electroplated with nickel. This core is inserted into a length of type 430 stainless steel cladding and the assembly is bonded by hot-swaging at 800 C. The irradiation performance of such a fuel element was examined by means of an MTR test. The results of this test strongly indicated that the desired lowering of UO/sub 2/ particle operating temperature was realized and that ferritic stainless steel is not unduly susceptible to irradiation dannage.
