MCUNED

RSICC CODE PACKAGE CCC-804

1. NAME AND TITLE

MCUNED: MCNPX Extension for Using Light Ion Evaluated Nuclear Data Library.

2. CONTRIBUTORS

Universidad Nacional de Educacion a Distancia, Madrid, Spain.

3. CODING LANGUAGE AND COMPUTER

Fortran 77; Linux (C00804PCX8600).

4. NATURE OF PROBLEM SOLVED

MCUNED is an MCNPX extension that handles a light ion evaluated nuclear data library. Using MCUNED, all MCNPX simulations involving transport of light ion could be solved using evaluated libraries instead of MCNPX built-in models.

5. METHOD OF SOLUTION

Modification of MCNPX dedicated subroutines.

6. RESTRICTIONS OR LIMITATIONS

MCUNED is operable on Windows, Linux, and MacOS systems, generally on systems compatible to MCNPX.

7. TYPICAL RUNNING TIME

Problem dependent.

8. COMPUTER HARDWARE REQUIREMENTS

LINUX system to apply the MCUNED patch on MCNPX release. Compiles on any system supporting MCNPX.

9. COMPUTER SOFTWARE REQUIREMENTS

GNU command “patch” installed in the system. The patch was applied to the MCNPX v2.7.0 source included in RSICC package B00004MNYCP04. All executables were generated statically and should work on most systems. Executables were reviewed and tested on a Xeon quad core system running Windows 7 and Windows XP and AMD Operton running RedHat Enterprise Linux 6. Excutables were compiled using Intel 11.1 for the Windows executable and 12.0.4 for the Linux executable.
