Abstract

Accurate analysis and prediction of the removal behaviors of the ionic corrosion products in the mixed-bed ion exchange (MBIE) column in the chemical and volume control system in PWR is significantly necessary for judgement of the coolant quality and the resin bed replacement. In this paper, a film-controlled multicomponent MBIE column model is adopted to investigate the removal behaviors of various cationic and anionic corrosion products. The results suggest that this model can effectively predict the effluent concentration, the saturation adsorption time, and the resin loading. The mass transfer coefficient and ratio of the anionic and cationic resin can impose obvious influence on the estimation of the resin utilization. The larger the mass transfer coefficient is, the shorter the saturation adsorption time, and the lower of the initial effluent concentration. The resin can achieve the maximum utilization when the cationic and anionic reins fails simultaneously.
