Abstract
The “Energy and Transmutation of Radioactive Waste” international collaboration uses different setups consisting of lead or uranium spallation target, which is surrounded by uranium or graphite blanket. Setups were irradiated by relativistic protons and deuterons to study transmutation of long-lived isotopes of spent fuel by spallation neutrons. The aim of this work is the determination of spatial distribution of fast neutrons in different points of the mentioned spallation setups. Neutron distributions were measured using activation detectors made of aluminum, bismuth, cadmium, copper, gold, indium, iron, lead, magnesium nickel, zinc, and zirconium. Irradiations were performed at the Joint Institute for Nuclear Research (Dubna, Russia) on the Nuclotron accelerator. The experimental data were compared with simulations using the MCNPX code.
