Rates of of oxidation and hydrogen absorption of iodideprocessed high- purity zirconium, commercial-grade zirconium, Kroll-processed reactor-grade zirconium, its 2.5% tin alloy, and 0.24% iron alloy with water vapor were measured at 650 to 850 deg C. The results were: (1) There was no great difference between the oxidation rates in water vapor and in oxygen. (2) The percentage of absorbed hydrogen in the specimens oxidized with water vapor were 1 to 20% of hydrogen produced by the oxidation process and decreased as the temperature became higher. (3) The amounts of absorbed hydrogen were larger in the specimens of higher oxidation rate than in those of lower oxidation rate. (auth)
