COMPUTATIONAL STUDY OF RADIATION CHARACTERISTICS INHERENT IN THE REACTOR GRAPHITE FROM RBMK-1000 UNITS
JOURNAL: 2024, ¹ 4 (29), p. 31-41AUTHORS: S.S. Selkin, D.A. Sharov, R.V. Plekhanov, D.L. Zinakov
ANNOTATION:
The paper focuses on a computational study seeking to estimate the radiation characteristics of reactor graphite from RBMK power units at their decommissioning stage based on the case study of Leningrad NPP and its unit ¹2. The calculations performed in the MCU-RBMK software via the Monte Carlo method were verified based on a data array with experimental specific activities of radionuclides found in the reactor graphite. The paper presents the estimated distribution of radioactive waste volumes represented by reactor graphite according to relevant waste categories with due account of amendments introduced into the radioactive waste classification system since January 1, 2024.
Keywords: reactor plant, RBMK-1000, graphite stack, radionuclides, activation, specific activity, Monte Carlo method, decommissioning, radioactive waste.
