A multiparametric recording system of radiation was created at the Khlopin Radium Institute to determine the composition of spent nuclear fuel to introduce it into fuel processing production cycles, in particular, to analyze the composition of liquids in hydrometallurgical conversion. The main task was to create a universal device (hardware and software complex) that can be adapted to determine the concentration of radioactive isotopes in various technological cycles by replacing detectors and/or reconfiguring software.
