A comparison of computational data, obtained with a variety of well-known radiation transport codes (MCNP, ANISN, FLUKA, ROZ6H)

A verification of the calculational data obtained with different well-known radiation transport codes and nuclear cross section sets (MCNP+ENDF/B, ANISN+HILO, FLUKA92) has been made by comparison with the results of precision ROZ6H+SADCO calculations and available experimental data. The results obtained with the MCNP+ENDF/B-5 package and ROZ6H+SADCO-computed data for neutron penetration in iron at energies E ≤ 14 MeV are in good agreement. For the calculations using ANISN at energies ≤400 MeV and FLUKA at energies ≤200 GeV, there are significant discrepancies both from the ROZ6H calculations and experimental data. The differences are discussed.
