Analysis Model and Parameter Optimization of a Silica Removal System for Boric Acid in Nuclear Power Plant

In order to improve the performance of the silica removal system for boric acid in nuclear power plants, the modified analysis model is established. The simulation of silica removal experiments using 200 Da and 250 Da molecular weight cut off (MWCO) reverse osmosis membranes is carried out by using this model. The calculation results meet the experimental data well, which demonstrates the accuracy and the applicability of the modified model. Further study on parameters optimization of this silica removal system based on this model is implemented as well; the effect of relevant parameters on the performance is analyzed. The conclusion is with reference significance for system design and operation.
