RSIC COMPUTER CODE PSR-091
1. NAME AND TITLE
COMAND: A Multigroup ANISN Cross Section Data Library Collapsing Code System.
Oak Ridge National Laboratory, Oak Ridge, Tennessee.
3. CODING LANGUAGE AND COMPUTER
Fortran IV; IBM 360/370.
4. NATURE OF PROBLEM SOLVED
COMAND (Collapse Multigroup ANISN Data) collapses ANISN libraries.
5. METHOD OF SOLUTION
COMAND accepts cards or tapes. It truncates upscatters, downscatters, combines ANISN data
from up to 5 sources, and allows for stripping groups (neutrons or gammas) from the base library.
Several weighting spectra can be read in and used on the same computer run.
6. RESTRICTIONS OR LIMITATIONS
7. TYPICAL RUNNING TIME
No study has been made by RSIC of typical running times for COMAND.
8. COMPUTER HARDWARE REQUIREMENTS
COMAND is operable on the IBM 360/370 computers.
9. COMPUTER SOFTWARE REQUIREMENTS
A Fortran IV compiler is required.
"COMAND - AMPX Module to Collapse ANISN Cross Section Libraries."
