Rate of Alloying of Uranium Alloys with Stainless Steel (Part I. 1800 to 2300 °F)

The rate of alloying between Type 304 stainless steel and metal fuels was investigated at 1800 to 2300 °F. The alloying times were determined by experimental couples in vacuum and by short fuel elements with a sodium or NaK bond between the fuel and the cladding. The fuels included unalloyed uranium, uranlum-molyhdenum alloys, and a Th-7.6 wt.% U alloy. Within the stated temperature range, unalloyed uranium alloys rapidly with the stainless steel, U-10 Mo somewhat slower, and Th-7.6 U the slowest of the fuels tested. The presence of a thin oxide film on the surface of a U-10 Mo fuel wafer substantially lengthens the time required to form the low-melting iron-uranium eutectic, whereas this effect is minor with unalloyed uranium.
