MATXS11 is useful for most high-energy calculations, including coupled neutron-photon-heating calculations in fusion blanket systems and the analysis of fast reactor cores.
The MATXS11 library uses 80 neutron groups and 24 photon groups and includes 105 materials from ENDF/B-VI (including changes through Release 2). The materials are given at up to 9temperatures ranging  from 300 K to 4000 K with typically 5 to 8 background cross sections for each temperature.
The weight function had a fast reactor or fusion blanket shape with a fusion peak at high energies and a 1/E + thermal Maxwellian extension at low energies. The Legendre order for the scattering matrices is P5. Photon production, photon interaction, KERMA, damage, and all ENDF partial cross sections are included. Thermal upscatter is not included.

4. METHOD OF SOLUTION

NJOY91.91 was used to process this library derived from ENDF/B-VI. MATXS11 is an update of the ENDF/B-V derived DLC-116/MATXS6A library, which was added to the RSIC collection in December 1985.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM:

6. TYPICAL RUNNING TIME

BBC converted MATXS11 to binary in less than  2 minutes on a SunSparcstation 2.

Two versions of the program BBC, respectively BBC V2.0  and BBC V2.5, were created and executed on two different computers:  1) SUN Solaris; 2) DEC 3000 Model 300X (Alpha/AXP Architecture Workstation). The CPU times required to run the executable BBC and perform the ASCII to binary conversion of the library TEXT11 (with the creation of the binary file MATXS) in the Sun Solaris platform and on the DEC-3000 Model 300 X (ALPHA-AXP Workstation) are 324.0 and 171.7 seconds respectively.

7. UNUSUAL FEATURES OF THE PROGRAM:

8. RELATED AND AUXILIARY PROGRAMS

The Fortran 77 program BBC is included in this package to convert the library to binary format for subsequent processing with the PSR-317/TRANSX2 code system to interface the MATXS cross-section libraries with nuclear transport codes for radiation transport calculations. Other functions of BBC include indexing MATXS libraries, and maintaining them by inserting, deleting, and extracting individual materials. Information on BBC, which was extracted from the TRANSX2 document, is given in APPENDIX  A. This version of BBC is configured to run on Sun workstations.

11. MACHINE REQUIREMENTS:

The filesize of the ASCII data library TEXT11 is 92.4 Mbyte. The corresponding binary file, created by the program BBC has a filesize of 32.8 MByte. The filesize of the executable BBC is 164  Kbyte.

13. OPERATING SYSTEM UNDER WHICH PROGRAM IS EXECUTED:

The program BBC was executed on two different UNIX systems, with the following specifications: 1) SUN Solaris platform, under SunOS 5.3, code compiled using the F77 compiler FORTRAN 3.0 from SUNPro; 2) DEC 3000 Model 300X (Alpha/AXP Architecture Workstation) under OSF/1 V2.1, code compiled using the  DEC Fortran compiler (f77) V3.4
