Abstract:

Data are presented on the activity of europium isotopes accumulated in the absorbing elements of the control units of propulsion reactors (7.4·10¹⁸ Bq), BN-600 and BOR-60 fast-neutron reactors (2.6·10¹⁷ Bq), and the SM-2 research reactor (4.8·10¹⁵ Bq). A universal computational procedure was developed for investigating the radiation characteristics of absorbing elements. Features of this procedure are demonstrated for the example simulating the isotopic composition of SM-2 absorbing elements. It is shown that the computed and experimental values of the parameters of the height distribution of the activity of europium isotopes agree within the limits of computational and measurement errors, and the computed total activity over the volume of an absorption element is 15% higher than the experimental value.
