METHOD OF TREATMENT OF REFINED OIL, PRODUCED AFTER TREATMENT OF RADIATED NUCLEAR FUEL Russian patent published in 1994 - IPC

Abstract SU 1382272 A1

FIELD: processing of waste. SUBSTANCE: the second phase of evaporation is integrated with fractionation of nitric acid, moreover, low-active tail solutions are used as reflux for both phases, which have to 1 mole/l of nitric acid. Regenerated concentrated nitric acid is brought out of the still in the second phase of the process or acid is brought out from the plate, being closest to the still, if tail solutions enter still, which have valuable components.
