Description

The first results of the study processes of neutrons generation in the uranium-lead subcritical assembly irradiated by 4 GeV deuterons are presented. The radial and axial distributions of radioactive capture reactions and the number of 238U fissions were obtained, as well as the spectral index σcapt238U / σf238U, in volume of lead target and uranium blanket. The total amount of 239Pu accumulated in the uranium blanket and total number of 238U fissions were determined. A comparison of neutron-physical characteristics of the U/Pb subcritical assembly relative to the energy of the primary deuteron beam (1.6, 2.52 and 4 GeV) was performed. A comparison between experimental data and calculations performed using the program FLUKA2008.
