DAMAGE-PREDICTOR, the computer code with the capability of simultaneously estimating the concentrations of radiolysis species, the electrochemical corrosion potential (ECP), and the crack growth rate of a reference crack in sensitized Type 304 stainless steels, was used to evaluate the responses of’ Dresden-2 and Duane Arnold boiling water reactors (BWRS) to hydrogen water chemistry (HWC) with the application of general catalysis (increasing the exchange current density) and general inhibition (decreasing the exchange current density). HWC simulations for these two BWRS were carried out for feedwater hydrogen concentrations of 0.0, 0.5, and 1.0 ppm and for exchange current density multipliers of...
