Abstract
An extended U/Pbassembly was irradiated with an extracted beam of 252 GeV deuterons from the Nuclotron accelerator of the Laboratory of High Energies within the JINR in Dubna Russia The layout of this experiment and first results are reported The Pbtarget diameter 84 cm length 456 cm is surrounded by a natUblanket 2064 kg and used for transmutation studies of hermetically sealed radioactive samples of 129I 237Np 238Pu and 239Pu Estimates of transmutation rates were obtained as result of measurements of gammaactivities of the samples Information about the spatial and energy distribution of neutrons in the volume of the lead target and the uranium blanket was obtained with sets of activation threshold detectors Al Y and Au and solid state nuclear track detectors SSNTD An electronic 3He neutron detector was tested online A comparison of experimental data with theoretical model calculations using the MCNPX program was performed yielding satisfactory results
