We demonstrate and approximate the effects of bromide ions on hydrogen peroxide generation under conditions of low oxygen concentration and over pressure of hydrogen. As has been shown these are conditions for which hydrogen peroxide generation is strongly reduced. We find that this reduction is strongly canceled by the presence of even small concentrations of bromide. The full Radiolysis Models seems to be required to accurately predict the effect, but we offer an empirical conservative model for use in the ANL Mixed Potential Model applicable to the prediction of UO2 degradation.
