Determining the Fast Neutron Flux Density and Transmutation Level Measurements in ADS by the Use of a Threshold Nuclear Reaction
Abstract
Determining the Fast Neutron Flux Density and Transmutation Level Measurements in the ADS by the use of a Threshold Nuclear Reaction. The aim of the project was determining the fast neutron flux density by using data from the Quinta experiment (E+T RAW collaboration). The experimental assembly based on natural uranium was irradiated by a 660 MeV proton beam. To gain the knowledge about the neutron flux inside the experimental assembly, nuclear threshold reactions of ( n, xn) type were used. The level of isotopes production are measured by the activation method using a gamma radiation HPGe detector. This paper describes the Quinta assembly, experimental results, calibration procedure and average high energy neutron calculation based on yttrium (Y-89) isotopes production. In the future, results and conclusions from an experiment like this could be useful to design accelerator-driven subcritical systems (ADS) or other 4th generation fast reactors. The investigation has been performed at the Laboratory of High Energy Physics, JINR.
