Transmutation of 129I, 237Np, 238Pu, 239Pu and 241Am Using Neutrons Produced in Target‐Blanket System “Energy & Transmutation” Bombarded by Relativistic Protons

Target‐blanket facility “Energy & Transmutation” was irradiated by a 2 GeV proton beam extracted from the Nuclotron Accelerator at the Joint Institute for Nuclear Research in Dubna, Russia. Radioactive samples made from iodine, neptunium, plutonium and americium were irradiated by spallation neutrons produced in the “E&T” facility. Transmutation reaction yields (residual nuclei production yields) have been determined using methods of γ‐spectroscopy. The energy spectrum of the neutron field has been studied by using a set of threshold detectors.
