3. DESCRIPTION OF PROGRAM OR FUNCTION

The program is intended to manipulate working format neutron and/or gamma cross section libraries, carrying out such operations as mixing materials, deleting unneeded groups, inserting response cross sections or whatever the user may require. It has been designed to make it easy to include new modules to cope with new requirements. The cross section libraries involved should preferably be in ANISN format, but if they are not, this too can be handled by adding new modules as needed.

This program is intended to supersede TOPICS (NEA-1406). TOPICS was intended for interactive use, but experience has shown that using it is somewhat difficult. Therefore it was redesigned for batch use (the input is written to a file and the program is then run using that file, instead of reading input directly from the keyboard).

4. METHOD OF SOLUTION

Each required operation is performed by a separate module (a set of subprograms).

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

Essentially none, variable dimensioning is used. However, TOPICS-B is not intended to be applied to basic nuclear data libraries (such as the ENDF/B series) or to flexible format libraries (e.g., the VITAMIN series). It is intended only for working format libraries like the BUGLE series.

6. TYPICAL RUNNING TIME:  A few seconds or minutes.

7. UNUSUAL FEATURES OF THE PROGRAM

TOPICS-B is designed for maximum flexibility. The modules may be called in almost any order, and new modules are easy to add.

8. RELATED AND AUXILIARY PROGRAMS

Testing TOPICS-B requires the use of BUGLE-96, both with and without upscattering.
OUTLIST makes it possible to check the contents of the file produced by module output in GIP form, which is unformatted. It converts the contents of the GIP file to the same (human-readable) format produced by module dump, so, when the contents should be identical, this can be checked simply by using the Unix diff utility.
