1. NAME AND TITLE

CARP-82: Multigroup Albedo Data using DOT Angular Flux Results.

2. CONTRIBUTOR

Oak Ridge National Laboratory, Oak Ridge, Tennessee.

3. CODING LANGUAGE AND COMPUTER

Fortran IV, Assembler Language; IBM 3033.

4. NATURE OF PROBLEM SOLVED

CARP is an acronym for Compilation of Albedo Reflection Parameters. CARP-82 allows processing of CCC-89/DOT angular flux tapes to produce albedo data for use in the CCC-127/MORSE computer code which is in the format required for the BREESE tape-writing program.

5. METHOD OF SOLUTION

CARP essentially performs data processing. During the processing of the data, the group structure may be collapsed, dose conversion factors may be applied to the fluxes, and--in the case of group reduction--group fluxes may be used for weighting.

6. RESTRICTIONS OR LIMITATIONS

The amount of data is so large that it is necessary to use the group reduction option in order to run CARP-82 on most computers.

7. TYPICAL RUNNING TIME

CARP-82 rarely takes more than 1/2 minute to run on an IBM 360/195 computer.

8. COMPUTER HARDWARE REQUIREMENTS

CARP-82 was designed for the IBM 360/370 computers. It is now operable on the IBM 3033 computer. It uses a scratch unit, reads either a DOT flux tape or one or more CARP storage tapes, and writes an output tape. A printer is used.

9. COMPUTER SOFTWARE REQUIREMENTS

Fortran IV and Assembler Language compilers are required.
