Abstract: Determinations of radionuclides in HLLW are described briefly. It includes the radiometric measurements of total α and β radioactivities and radiochemical analysises of neptunium, plutonium and americium, fission products ~(90)Sr, ~(147)Pm and some γ-radionuclides from the reprocessing plant of nuclear fuel A set of data obtainted is significant for study of treatment and disposal of high-level liquid waste.
