FIELD: physics.
SUBSTANCE: invention relates to the reprocessing of spent nuclear fuel (SNF) of nuclear power plants (NPPs), in particular to the technology of handling highly active raffinate of the extraction cycle for reprocessing the product of the acid dissolution of SNF in the concentration stage before recycling by curing. The method for evaporating a highly active raffinate from processing spent nuclear fuel, wherein the process for evaporating the raffinate nitrate is carried out in the presence of an amino acid or an amino acid and a hydroxycarboxylic acid in the vat solution.
EFFECT: invention allows to increase the multiplicity of evaporating the highly active raffinate.
