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.
