Neptunium-237 samples were irradiated in a spallation neutron fi eld 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 fi ssion products and one actinide were identifi ed. Fission product activities yielded the number of fi ssions. 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 fi nd out if and how the incineration rate depended on parameters of the accelerator beam.
