JOURNAL: 2021, ¹ 2 (15), p. 21-32AUTHORS: A.O. Paviluk, S.G. Kotlyarevskij, R.I. Kan, A.G. Volkova, E.V. Zakharova, M.A. Ilyukhina, V.B. Gorshkov, A.N. Dorofeev, B.S. Zinnurov, Å.A. Komarov
ANNOTATION:
This paper presents some methodological approaches to the characterization of graphite blocks based on difficult-to-measure 14C and 36Cl radionuclides during graphite stack dismantlement at uranium-graphite reactors (UGR) developed by JSC PDC UGR. It presents the testing results of the developed methods applied during RBMK-1000 graphite stack block characterization at the Leningrad NPP.
Keywords: irradiated graphite, difficult-to-measure radionuclides, radioactive waste radiation characteristics, radioactive waste, non-destructive method, radionuclide vector.
