The target assembly QUINTA consisting of 512 kg natural uranium was irradiated by deuteron and carbon beams with energies 1, 2, 4 and 8 GeV (deuterons), 24 and 48 GeV (carbon). Spatial distribution and total number of capture reaction and fission reaction rates was obtained using the activation technique. The integral number of fissions reactions in the volume of uranium target remains approximately constant within our statistical errors for 1, 2, 4 and 8 GeV deuteron beams and for 24 and 48 GeV carbon beams (per one primary particle and per 1 GeV of beam energy). For the integral number of capture reactions with deuteron beams we have seen maximum at 2 GeV. Some of the obtained experimental data was analyzed using the MCNPX transport code. For spatial distribution of reaction rates in case of 4 and 8 GeV deuteron beams we have seen a discrepancy between the experimental and calculated values in backward direction.
