Proposal of new oxidation kinetics for sponge base E110 cladding tubes material

Abstract

Study of high temperature steam oxidation kinetics during the high temperature oxidation was carried out on the sponge base E110 cladding tubes material in the temperature range 600–1300 °C. The oxidation kinetics derived from the weight gain measurements showed a parabolic rate law for temperatures 1100 °C and higher only. For lower temperatures in range 800–1050 °C especially, the parabolic law leads to very conservative prediction. Therefore, the new oxidation kinetics, different from the parabolic law, was designed. The experimental database containing more than 800 data points was compared with the new developed UJP-correlation and available correlations for E110 and Zircaloy alloys. Statistical analysis for all tested correlations was provided.
