New Understanding in Hydrogen Peroxide Decomposition with Application in BWR Water Chemistry Simulations

摘要

The introduction of the hydrogen peroxide oxidation reaction is important to have good agreement between modelling and measurements in the general case. Only then can a reasonably low passivity current be used in the model. The consumption and production of hydrogen, oxygen, and hydrogen peroxide by the electrochemical reactions are important in systems with high area-to-volume ratio. The heterogeneous decomposition of hydrogen peroxide is due to the electrochemical reactions of hydrogen peroxide oxidation and reduction. There is no or little influence of other, non-electrochemical, reactions.
