Other Information: The maximum number of ordinates is 60 which may be divided arbitrarily among the groups subject to the restriction that the ordinate schemes be symmetric about, but not include, mu=0 in each group. The corresponding group number limit is 30 with two ordinates per group. Other limitations include - 20 compositions 50 regions 50 source regions
Other Information: The maximum number of groups is 2000 and the maximum number of ENDF/B materials is 10 (or 5 in age calculations). The number of center-of-mass elastic scattering moments read from ENDF/B must be less than 7. The resonant cross sections for any material are ignored
