The available data on the reactions of Zircaloys, stainless steels, uranium metal and uranium dioxide with steam at temperatures above about 1000/sup 0/C and the reactions of core melts during concrete penetration have been reviewed and assessed for the IDCOR Program. The uranium metal is included because small quantities can be formed from the high temperature interaction between Zircaloy and uranium dioxide and because the uranium data adds insight into the nature of the reactions of core materials with steam. Thermodynamic analyses and comparisons of reaction rate data have been made. One of the purposes of this assessment was to develop fully the information generated in the early studies of oxidation processes, particularly the extensive program carried out at ANL from about 1960 to 1968.
