... and its axial variations and evaluation of hydrogen solubility in oxygen-dissolved Zircaloy-2. The fuel channel box was found to contribute to the axial variations of oxide layer growth and hydrogen uptake of the fuel pins by acting as a source of hydrogen and a sink of oxygen. The evaluation of hydrogen...
