3. DESCRIPTION

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
FORMAT: ANISN

 

NUMBER OF GROUPS: 10 neutron, 7 gamma-ray

 

NUCLIDES: 78 materials (mixture components) Flux trap, Core, Zircaloy-4, D2O, H2O, SS-304, Air, Boral, Lead, B4C+Epoxy, Steel, Magnetite, Ordinary concrete, Limonite, Bor induced high density concrete.

 

ORIGIN: VITAMIN-C fine-group cross section library

 

WEIGHTING SPECTRUM: weighting functions representative of a 20% enriched uranium fueled, D2O reflected and pool type research reactor.

 

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
Starting with the DLC-41C/VITAMIN-C fine-group cross section library, a composition-dependent coupled few-group (10n,7g) self-shielded microscopic ANISN-formatted cross section library was generated to be used for research reactor shielding calculations. FGXRRS was generated by collapsing DLC-41C/VITAMIN-C using the spectra of the zone-dependent total fluxes.

4. METHODS

The data were collapsed from a fine-group structure using the weighting functions representative of a 20% enriched uranium fueled, D2O reflected and pool type research reactor. Thus the application of this data for problems not similar to this type of problem should be done with caution.

8. RELATED OR AUXILIARY PROGRAMS

The basic cross section source data for the generation of the FGXRRS cross section library was DLC-41C/VITAMIN-C neutron, secondary gamma-ray production, and gamma-ray interaction cross section library in AMPX master interface format. PSR-63/AMPX-II modules were used to prepare FGXRRS, which includes 78 materials. The Legendre order of expansion for angular distribution is 3.

GITAPE: Group Independent TAPE processing.
