APRFX1; 99-group DLC-2B library group-collapsing. [CDC6600; FORTRAN IV]
Technical Report
·
OSTI ID:6343437
APRFX1 collapses and combines cross section sets for multigroup transport calculations. It performs group collapsing for as many isotopes, mixtures, and Legendre expansion sets as desired from the DLC-2B library. The DLC-2B library structure employs tenth lethargy unit intervals from 15 MeV to 111 keV and quarter lethargy intervals down to 0.414 eV. A 100th group 0.0 to 0.414 eV is used as a sink group. The code also determines the broad-group input source and generates averaged neutron velocities for use with transport calculations.CDC6600; FORTRAN IV.
