P oS(Baldin ISHEPP XXII)056 Measurements of Np-237 incineration in ADS setup
2015
Np-237 samples were irradiated in spallation neutrons produced in ADS setup QUINTA. Three experiments were carried out. The accelerated beam consisted of deuteron ions of energy 2, 4 and 8 GeV respectively. The method was based on gamma-ray spectrometry measurement. During analysis of the spectra several fission products and one actinide were identified. Fission product activities gave the number of fissions. The actinide (Np-238), a result of neutron capture by Np-237 gave the number of captures.
Np-237 incineration study in various beams in ADS setup QUINTA
Nukleonika
Neptunium-237 samples were irradiated in a spallation neutron field produced in accelerator-driven system (ADS) setup QUINTA. Five experiments were carried out on the accelerators at the JINR in Dubna - one in carbon (C6+), three in deuteron, and one in a proton beam. The energy in carbon was 24 GeV, in deuteron 2, 4 and 8 GeV, respectively, and 660 MeV in the proton beam. The incineration study method was based on gamma-ray spectrometry. During the analysis of the spectra several fission products and one actinide were identified. Fission product activities yielded the number of fissions. The actinide (Np-238), a result of neutron capture by Np-237, yielded the number of captures. The main goal of this work was to find out if and how the incineration rate depended on parameters of the accelerator beam.
