The air oxidation kinetics of Zr alloys claddings immersed in seawater

Due to hydrogen explosion in the Fukushima nuclear power plant, Analysis of fuel cladding became one of important issues. And we need the research related seawater because seawater was flowing in the reactor. Oxidation reaction between Zr cladding and steam cause hydrogen explosion. Thus we have to know the detail information related with oxidation kinetics of fuel claddings under the mixture of air and steam at high temperature and oxidation rate of Zr cladding immersed in seawater. There are not available data related with the oxidation of Zr alloys under the mixture of air, steam and seawater. The goal of the study is to obtain the fundamental data and help safety analysis
