Determination of the Composition of the Filter Cake Formed by Filtration of Solutions from Reprocessing of Spent Nuclear Fuel of BN-600 Reactor

Alternative procedures for the dissolution of the solid phase (filter cake) of sludge formed by filtration of a spent nuclear fuel solution through cartridge and bulk filters were tested. Quite successful dissolution of the filter cake from the cartridge filter regeneration is ensured by successive...

Description
Summary:Alternative procedures for the dissolution of the solid phase (filter cake) of sludge formed by filtration of a spent nuclear fuel solution through cartridge and bulk filters were tested. Quite successful dissolution of the filter cake from the cartridge filter regeneration is ensured by successive treatment with alkali and acid solutions. Attempts to dissolve the filter cake from the bulk filter regeneration failed. The chemical and radiochemical composition of the filter cakes was evaluated. The results obtained will be used for assessing the nuclear and radiation safety and for developing procedures for the management of filter cakes from the filter regeneration.
