지르칼로이-4의 고압 고온 수증기에서 산화 반응 속도
Zricaloy-4 Oxidation Kinetics in High-Pressure High-Temperature Steam
초록
A model for quantifying the effect of steam pressure on the oxide thickness growth was developed based on the experimental data available. First, empirical equations for the thickness estimation of oxide formed in 1 atm steam were made. The oxide growth kinetics turned out to be dependent on 0.4th power of oxidation time. With an assumption that the transition oxide thickness be only a function of temperature, a model for the enhancement of steam pressure on oxide growth was developed. The enhancement coefficient for steam pressure is calculated to be 0.01~0.013
