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

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. | Proposal of new oxidation kinetics for sponge base E110 cladding tubes material EPJ Nuclear Sci.

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. 1 Introduction and Zry-4 in different atmospheres have been conducted Grosse 4 Steinbrück et al. 5 Hozer et al. 6 in Germany and Hungary. Zirconium-based alloys are widely used for nuclear reactor In the past years several experimental series have been components such as fuel claddings grid spacers and guide performed at the UJP PRAHA . UJP with E110 tubes. These alloys combine low neutron absorption sponge based cladding alloy. The aims of these experiments behaviour and good mechanical and corrosion properties were to study and
