1.         NAME AND TITLE

SCAMPI:     Collection of Codes for Manipulating Multigroup Cross Section Libraries in AMPX Format.

                    

2.         CONTRIBUTORS

ENEA/FPN-FISNUC (Nuclear Data Centre), Bologna, Italy, through OECD Nuclear Energy Agency Data Bank, Issy-Les Molineaux, France.

3.         CODING LANGUAGE AND COMPUTER

Fortran 77 and C on IBM RS/6000, Sun, DEC.

RSICC ID: P00352MNYWS01; NEADB Identifier is: PSR-0352/05.

4.         NATURE OF PROBLEM SOLVED

SCAMPI (Scale and Ampx Processing Interface) was prepared to facilitate the calculation procedure for creating problem-dependent cross sections from problem-independent multigroup data. It consists primarily of modules derived from PSR-315/AMPX-77 and CCC-545/-SCALE4.3. It consists primarily of the modules AIM, AJAX, ALE, ALPO, BONAMI, CORECTOL, CSAS, FILTER, GIP, ICE, LAVA, MALOCS, NITAWL, PERFUME, RADE, UNITAB, WAX, and XSDRN derived from PSR-315/AMPX-77 and CCC-545/SCALE4.3. The CSASIN full-screen PC input processor that guides the user through the CSAS module input has been modified for SCAMPI and is also included. The CSAS module was modified to remove the interface with KENO and automatically provide output of an ANISN-formatted working library for use with codes such as CCC-543/TORT-DORT,[*] CCC-254/ANISN-ORNL or CCC-474/MORSE-CGA. The GIP program was extracted from the CCC-543/TORT-DORT 2.12.14 package. Note that no data libraries are included in SCAMPI.

5.         METHOD OF SOLUTION

The CSAS control module in SCAMPI uses engineering data and keyword input to perform resonance self-shielding, Doppler-broadening, and temperature interpolation of the thermal-scattering matrices for the specified geometry and mixtures through calls to SCALE and AMPX-77 functional modules. Thus, CSAS is an automated procedure which can create problem-dependent cross sections from data libraries in AMPX master library format.

6.         RESTRICTIONS OR LIMITATIONS

Data libraries must be in AMPX-77 format. The CORECTOL module can be used to convert AMPX-II master libraries to this format.

7.         TYPICAL RUNNING TIME

Run time is entirely dependent on the machine and the problems being solved.

8.         COMPUTER HARDWARE REQUIREMENTS

SCAMPI runs on Unix or Linux machines. To facilitate installation, makefiles are included for IBM RS/6000, Sun, DEC Alpha, HP and Linux. Approximately 25 MB of disk space is required to build the executables.

9.         COMPUTER SOFTWARE REQUIREMENTS

The programs are written in Fortran 77 and C. SCAMPI runs on these systems: IBM AIX with both the f77 and xlf90 compilers, Sun with both Solaris and SunOS4, DEC Alpha with OSF/1 and Ultrix, and HPUX 9.0.3.
