THE TEST RIG FOR INSPECTION OF SPENT FUEL ASSEMBLIES OF RESEARCH REACTORS OF THE STATE SCIENTIFIC CENTER OF THE RUSSIAN FEDERATION RESEARCH INSTITUTE OF ATOMIC REACTORS.

The report describes the technical characteristics and possibilities of the multifunctional Test Rig for inspection of spent fuel assemblies (SFA) of the research reactors (RR) stored in the water pools at the Central Storage Facility (CSF) of spent nuclear fuel (SNF). The Test Rig (TR) will allow us to check the presence of the fuel assembly in the storage, to assess its selfprotection, to identify the fuel assembly and the fuel type, to detect failures of the structural integrity during long-term storage and to check the fuel rod cladding leak-tightness. It is supposed that the TR constructed under the program of upgrading and automatization of the Material control and Accountability (MC&A) system at the RIAR will substantially reduce the possibility of unauthorized handling of spent nuclear fuel.
