Monte Carlo modeling of secondary neutron and proton fluxes from the surface of subcritical assemblies under irradiation with high energy proton beams. (English) Zbl 1156.82427

Summary: The essence of the work presented here is to show the comparison of fluxes of secondary particles emitted from subcritical assemblies being irradiated with proton beams. These assemblies, at present under investigation at the Joint Institute for Nuclear Research, Dubna are the Subcritical Assembly in Dubna (SAD), with \(k_{eff} = 0\),95-0.98 and the “Energy plus Transmutation” with \(k_{eff} = 0.24\). Monte Carlo modeling is used to forecast production of secondary proton and neutron fluxes in different subcritical assemblies under irradiation with protons in the energy range from 660 MeV up to 2.0 GeV. Neutron and proton spectra emitted from the surface of these assemblies are calculated using a version of the codes CASCADE and MCNP-X.
