1. NAME AND TITLE

MOCUP: MCNP/ORIGEN Coupling Utility Programs.
 

2. CONTRIBUTOR

Idaho National Engineering Laboratory, Idaho Falls, Idaho.
 

3. CODING LANGUAGE AND COMPUTER

C; DEC Alpha and HP workstations running X11R4 and MOTIF (P00365/DALPU/00).
 

4. NATURE OF PROBLEM SOLVED

MOCUP is a series of utility and data manipulation programs to solve time- and space-dependent coupled neutronics/isotopics problems.
 

5. METHOD OF SOLUTION

The neutronics calculation is performed by the Los Alamos National Laboratory code system, version 4a or later (CCC-200 or CCC-660),and the depletion and isotopics calculation is performed by CCC-371/ORIGEN2.1 developed at Oak Ridge National Laboratory. MCNP and ORIGEN2.1 are NOT included in this package. MOCUP consists of three utility programs (mcnpPRO, origenPRO, compPRO) to, respectively, search the MCNP output and tally files for relevant cell and tally parameters, prepare ORIGEN2.1 input files and execute the ORIGEN2.1 runs, and search ORIGEN2.1 punch files for relevant isotope concentrations and produce new MCNP input files. A graphical user interface is provided for execution convenience.
 

6. RESTRICTIONS OR LIMITATIONS

At present, no mechanism exists for automatic serial execution of the program modules. The user must interface with the GUI to run each of the modules.
 

7. TYPICAL RUNNING TIME

For the sample problem provided, a two timestep calculation takes approximately 60 minutes on a DEC 5000. This includes the MCNP and ORIGEN2.1 calculations.
 

8. COMPUTER HARDWARE REQUIREMENTS

DEC Alpha workstations with OSF/1, DEC 5000 workstations with Ultrix, or HP workstations with HP/UX. The disk and memory requirements are dictated by MCNP and ORIGEN2.1.

Implementation has been limited to DEC Alpha workstations with OSF/1, DEC 5000 workstations with Ultrix, and HP workstations with HP/UX. Other implementations are not supported at this time.
 

9. COMPUTER SOFTWARE REQUIREMENTS

Compilation requires an ANSI C compiler. X11R4, the Motif tool kit, MCNP and ORIGEN2.1 must be installed on the computer. MOCUP runs on DEC Alpha running OSF/1 V2.0.
