Abstract:

New Barnyard, a moments code, was written to calculate multigroup neutron macroscopic cross sections. Total, absorption, fission, and scattering transfer group to group cross sections can be calculated. The transport cross section, diffusion coefficient, and the average cosine of the scattering angle can also be calculated for each group. The energy range of these cross sections extends from 14.918 MeV to .4139 eV. Two versions of the moments code were written so that two different data sources could be used. PO through P8 elastic scattering transfer cross sections can be calculated for 20 broad groups.
