3. NATURE OF PHYSICAL PROBLEM SOLVED

FEDGROUP transforms card image evaluated neutron nuclear data files into working format RFOD; calculates group constants for reactor physics purposes (group averaged infinite dilute and resonance screened cross sections, elastic and inelastic energy transfer matrices), compiles group constant libraries. Types of evaluated files which can be processed are: ENDF/B, KEDAK, UKNDL and Livermore ENDF in ENDF/B format.

FEDROUP-C treats in addition ENDF/B-V files.

[ top ]

4. METHOD OF SOLUTION

For numerical integration trapezoidal Simpson's and Romberg's rules are used.

[ top ]

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM: There are no essential restrictions.

[ top ]

6. TYPICAL RUNNING TIME

FEDGROUP-C: Production of U-235 69-WIMS group structure from ENDF/B-V takes about 1400 seconds on CYBER 174 for one temperature and seven different values of the background potential scattering cross section.

IAEA0830/08

The 3 test cases included in this package ran at NEA-DB on a CYBER CDC 830 computer. The following CPU times were required: case 1: 50 secs; case 2: 336 secs; case 3: 2314 secs.

IAEA0830/09

The 3 test cases included in this package were executed by NEA-DB on a VAX 8810 computer in 13 minutes of CPU time.

IAEA0830/10

The installation of this version plus the execution of the three test problems requires about 5000 CPU seconds and 1000 I/O seconds on a CDC830.

7. UNUSUAL FEATURES OF THE PROGRAM

Relatively small storage requirements due to the dynamical programming; flexibility concerning the evaluated nuclear data files and the resulting group constant libraries.

[ top ]

8. RELATED AND AUXILIARY PROGRAMS

- Various utility programs for manipulating the data;
- FLMERGE to merge group constant sets, each covering only a part of the required energy range into a single group constant set - FLACOF to convert FLANGE results into FEDGROUP library format;
- FEDWIM interface program for updating the WIMS library;
- FLANGE-AE to calculate group constants in the thermal region.
- FEDEN A program to convert FEDGROUP GCL to ENDF/B-5 format.
