Electrodialysis Processing of Deactivated Vat Residues of NPP

Abstract

A study of the possibility of using Electrodialysis for the simultaneous separation of multicomponent solution of deactivated vat residues of the ion-selective cleaning plant (ISCP) NPP for three chemical reagents is presented. A prototype of chemical component recycling plant with a capacity of 5 liters per hour was designed and built. Studies have been carried out confirming the possibility of obtaining acid and alkali from deactivated vat residues (VR) of NPP using Electrodialysis. It is proposed use results of work when developing a compact pilot plant for processing of deactivated vat residues of NPP with WWER. The use of Electrodialysis to separate of multicomponent deactivated solution VR ISCP NPP allow effectively remove boron components for reuse.
