IAEA0887 WIMSCORE-ENEA.

1. NAME OR DESIGNATION OF PROGRAM:  WIMSCORE-ENEA

3. DESCRIPTION OF PROGRAM OR FUNCTION

The code processes the WIMS-D/4 binary output files for producing two-group microscopic cross sections and macroscopic lattice cell constants (zone and cell macroscopic cross sections, D, M, and K-infinity) in a more flexible format needed for reactor burnup codes like CITATION, for reactor dynamics codes like NADYP-W and for other reactor codes. The purpose of the WIMSCORE-ENEA code is to facilitate the automation of data transfer between the cell calculation code WIMS and the diffusion-burnup codes.

4. METHOD OF SOLUTION

The code spatially homogenizes and group collapses the various cross sections into two-group homogenized microscopic cross sections using the flux per mesh for each energy group for WIMS multigroup lattice calculations.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM:  None.

6. TYPICAL RUNNING TIME

For a typical run with 27 WIMS energy groups, 10 large burnup steps, 1 second is required on a IBM/3090 computer.

NEA-DB executed the test case included in this package  on an IBM 3090 computer in s.6 seconds of CPU time.

7. UNUSUAL FEATURES OF THE PROGRAM:  None.

8. RELATED AND AUXILIARY PROGRAMS

Use is made of the VARY storage manipulation package (NEA 0473/01).
WIMSCORE generates output files to be used by the codes TDB, TRITON, CITATION.

11. MACHINE REQUIREMENTS:

To run the test case on an IBM 3090, 2050 kB of main storage are required.

13. OPERATING SYSTEM UNDER WHICH PROGRAM IS EXECUTED:
Compiler: FORTRAN H-EXTENDED in MVS-IBM System.

MVS/XA (IBM 3090) with compiler VS FORTRAN LEVEL 2.4.0.

14. OTHER PROGRAMMING OR OPERATING INFORMATION OR RESTRICTIONS

Main storage depends on data array DIMENSIONS defined in the MAIN routine, but can easily be adjusted. Original assembler storage allocation routines mentioned in the report are not included in the  package.
   Only WIMS pin cell calculation has been tested.
