NEA-1170 PROF-DD.

1. NAME OR DESIGNATION OF PROGRAM:  PROF-DD.

3. DESCRIPTION OF PROGRAM OR FUNCTION

The code system PROF-DD generates a multi-group double-differential cross section library DDX from evaluated data in ENDF/B-IV or ENDF/B-V format. The system  consists of the following five modules:
PROF-DDX is the main module of the system. It calculates the multigroup DDX and stores them on a master PDS file.
MCFILEF generates a control file for PROF-DDX, which contains energy group and angle bin structures.
SPINPTF prepares an input data file for PROF-DDX by combining the control file wth other input data.
DDXLIBMK edits a DDX library from the master PDS file for transport calculations.
RESENDD performs resonance cross section and Doppler broadening calculations.

4. METHOD OF SOLUTION:

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

The numbers of energy groups and angle bins are less than 150 and 40, respectively.

6. TYPICAL RUNNING TIME

It depends on the nuclide processed. Running  time for Lithium-6 is about 100 sec on FACOM M-380.

7. UNUSUAL FEATURES OF THE PROGRAM

Double-differential form cross sections can correctly take into account the reaction kinematics and the scattering anisotropy in the multi-group approximation.

8. RELATED AND AUXILIARY PROGRAMS

ANISN-DD, DOT-DD and MORSE-DD; these are one-, two- and three-dimensional transport codes, respectively, which use the double-differential form cross section library produced by PROF-DD.

11. MACHINE REQUIREMENTS:  4.5 MB core memories are required.

13. OPERATING SYSTEM UNDER WHICH PROGRAM IS EXECUTED:  FACOM OS-IV/F4.

14. OTHER PROGRAMMING OR OPERATING INFORMATION OR RESTRICTIONS

A PDS file (Partitioned Data Set) is used with undefined record format. A  member contains an array of binary data. An assembler routine is prepared to read and write a member by Fortran statements.
