3. DESCRIPTION OF PROBLEM OR FUNCTION

This code transforms DOT directional fluxes into current out per steradian per eV per current incident. During this processing, 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.

4. METHOD OF SOLUTION

CARP is essentially a data processor for DOT angular flux tapes.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

At present albedo data is available for four materials: water, ordinary concrete, carbon steel and steel-over-concrete. The 51 neutron-25 gamma group  structure was used and the differential angular albedoes are a function of five incident polar directions and 30 reflected directions. See the CARP report for details. Since the amount of data is so large, it is necessary for users to use the group reduction option in order to run on most computers. Conversion to non-IBM computers may be difficult because of the IBM assembly language that is part of the CCCC package for I-O. Users refer to Ref. 4 for details on the functions of the CCCC routines. Some of the assembly language can be replaced by dummy routines.

6. TYPICAL RUNNING TIME

Rarely exceeds 0.5 minute on IBM 360/195.
CARP-82 (PSR-0313/03): The test case was run by NEA-DB on IBM 3081 in 5 CPU seconds.

8. RELATED AND AUXILIARY PROGRAMS

This code processes data from a DOT angular flux tape and produces an albedo output tape for the BREESE  tapewriting program. BREESE then prepares an albedo tape for input to MORSE. A report on an earlier version of BREESE is available, but please note that the CARP output tape is compatible only with BREESE -II which is currently being documented. CARP is an acronym for Compilation of Albedo Reflection Parameters.
