Effect of NJOY and Grucon Processing Codes in Nuclear Data Preparation for Steel Nuclides.

Blokhin, A. I.; Mitenkova, E. F.; Novikov, N. V.

The observed differences of the neutron fluxes between experiments and calculations on passage of neutrons through thick layers of iron and steel are conditioning the use of better models for representing the scattering cross-sections and energy-angle distributions of neutrons in elastic and inelastic scattering. The effect of the NJOY99 and GRUCON prepared nuclear data for Fe, Cr, and Ni on Keff and functionals related with the neutron fluxes in systems with a thermal and a fast spectrum is studied. The calculations were performed using MCNP5, and all nuclear data fi les are based on ENDF/B VII.1.
