Supercritical freon-22 and liquid freon-134a can dissolve 11÷12 and 19÷25 vol.% of tributylphosphate (TBP), respectively, in dynamic conditions. These solutions efficiently extract nitric acid up to mole ratios [HNO₃] : [TBP] from 1.5:1 to 2.3:1. The solution of TBP · nHNO₃ adduct in freon-134a efficiently dissolves uranium and mixtures mimicking the irradiated nuclear fuel from reactors of VVER type.
