3. DESCRIPTION OF PROGRAM OR FUNCTION

A system for comparing multigroup cross sections generated by NJOY, GROUPIE, FLANGE-II, ETOG-3 and XLACS. This system comprises the COMPAR program and interface (auxiliary) programs developed for each of the programs under consideration. These are REDCOMP for GROUPIE, FLACOMP for FLANGE-II, ETOCOMP for ETOG-3 and XLACOMP for XLACS. For the NJOY program there is RGENDF, a program developed apart from this system. It is a modular system in which the inclusion of new multigroup cross section generating program requires no more than the development of a new interface module.

8. RELATED AND AUXILIARY PROGRAMS

The auxiliary programs FLACOMP, ETOCOMP, XLACOMP and REDCOMP are used to convert the libraries generated by FLANGE-II, ETOG-3, XLACS and GROUPIE, respectively, to  the input library format for COMPAR.
