First results studying the transmutation of 129I, 237Np, 238Pu, and 239Pu in the irradiation of an extended natU/Pb-assembly with 2.52 GeV deuterons

Original language description

Preliminary results of the first experiment with deuteron beam with energy 2.52 GeV at the electronuclear setup which consists of Pb-target (diameter 8.4 cm, length 45.6 cm) and natU blanket (206.4 kg), transmutation samples of 129I, 237Np, 238Pu and 239Pu (radioecological aspect) are described. Hermetically sealed samples in notable amounts are gathered in atomic reactors and setups of industries which use nuclear materials and nuclear technologies were irradiated in the field of neutrons produced in the Pb-target and propagated in the natU-blanket. Estimates of transmutations were obtained as result of measurements of gamma activities of the samples. The information about the space and energy distribution of neutrons in the volume of the lead targetand the uranium blanket was obtained with help of sets of activation threshold detectors (Al, Co, Y, I, Au, Bi and others), solid-state nuclear track detectors, 3He neutron detectors and nuclear emulsion.

Studovalo se rozložení produkce neutronů v sestavě a transmutace vzorků radioaktivních materiálů 129I, 237Np, 238Pu a 239Pu

Czech description

V práci jsou prezentovány předběžné výsledky prvního ozařování sestavy složené s olověného terče a uranového blanketu svazkem deuteronů s energií 2,52 GeV. Studovalo se rozložení produkce neutronů v sestavě a transmutace vzorků radioaktivních materiálů (129I, 237Np, 238Pu a 239Pu). Výsledná experimentální data byla srovnávána se simulacemi pomocí programu MCNPX.
