Abstract

The results of the development and implementation of a tangential filtration procedure for the treatment of mother liquors from ammonia precipitation of uranium are presented. The tangential filtration installation at RT-1 plant was put into operation in 2019. The productive capacity of the installation with respect to permeate is 450 dm³/h on the average. Up to 50 m³ of the mother liquor can be processed in one filtration cycle. The decontamination factor is 10³ for α-emitters and 10² to 10³ for β-emitters. The resulting permeate corresponds in its activity to the LLW category.
