MECHANICAL PROPERTIES OF STAINLESS STEEL-UO$sub 2$ DISPERSION FUEL ELEMENTS
Technical Report
·
OSTI ID:4174986
Mechanical properties of stainless steel-- UO/sub 2/ dispersion fuel elements were determined on specimens fabricated (a) by the cold-binder extrusion and hot swaging technique, (b) by the single hot-coextrusion method, and (c) by the hotcoextrusion method followed by a second hot-extrusion, hot-rolling, swaging, or drawing. Tensile test results show that cold-binder material has very good tensile properties with the exception of ductility. Bend tests show thai coarse oxide material has better ductility than the fine oxide both before and after irradiation. Although the fuel element material is low in ductility, test results indicate that completed fuel elements composed of a dispersion of UO/ sub 2/ clad in stainless steel have fair mechanical properties for reactor use even after high burnups.
