3. DESCRIPTION OF PROBLEM OR FUNCTION

Generates flux-averaged, infinite-dilution, group constants and the scattering matrix.
top ]
4. METHOD OF SOLUTION

The code reads from the ENDF/B tape the data for the processed material in any form or option in which these data are read.  In one run the code treats up to an entire ENDF/B tape.
It searches for the first requested material, processes it, searches for the second, etc. until the list of materials is exhausted.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

Number of energy groups up to 30. Number of weighting flux points up to 150. The materials to be processed should be specified in the same order as on the ENDF/B tape.

6. TYPICAL RUNNING TIME

The test case has been executed by NEA-DB on  IBM 3081 in 45 CPU seconds.
top ]
7. UNUSUAL FEATURES OF THE PROGRAM:  Processes all ENDF/B version tapes from I to V.
