AbstractAbstract
[en] The model of uniform corrosion of E110-type and E635-type alloys is developed. Model is integrated in START-3 fuel performance code. Model is capable to predict oxidation and hydriding of Zr-based fuel components under PWR (up to 10 ppm Li) and WWER conditions within ±25% uncertainty. Oxygen content in coolant for WWER and PWR uprated modes of operation were analyzed with the model of the two-phase coolant radiolysis. α-radiolysis of steam increases oxygen content if coolant boiling takes place. Additional experimental research is to be done to narrow uncertainties in evaluation of O2 content
