NEA-1048 ETOBOX.

1. NAME OR DESIGNATION OF PROGRAM:  ETOBOX.

3. DESCRIPTION OF PROGRAM OR FUNCTION

Preparation of a cross section  library for the code BOXER from a basic library in ENDF/B format.

4. METHOD OF SOLUTION

According to the recommendations in the ENDF/B  manuals: M.K. Drake: Data formats and procedures for the ENDF cross  section library, BNL 50274 (T-601) (October 1970) and ENDF 50496 (October 1979). ENDL-102.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

Only the formats until ENDF/B-5 can be treated. ETOBOX is not adapted to ENDF/B-6. The gamma-part of ENDF/B is not treated.

6. TYPICAL RUNNING TIME

On a SUN SPARC station 5: between a few seconds for a simple problem (for instance: group constants of C-12  at 0 K) to 3000 sec (U-238 with approx. 23000 lethargy points for the resolved resonances).

7. UNUSUAL FEATURES OF THE PROGRAM

All the variables, including the integers, must be represented in 64 bit words.

8. RELATED AND AUXILIARY PROGRAMS

ETOBOX is the library preparation code of the ELCOS system for the quasistationary modeling of LWR. Some subroutines are stored on the subroutine library LWRLIB. ETOBOX needs the data from a basic cross section library like JEF-1 or ENDF/B-5.

11. MACHINE REQUIREMENTS:  The core memory should not be less than about 16 Mbytes.

13. OPERATING SYSTEM UNDER WHICH PROGRAM IS EXECUTED:  On CYBER: NOS/VE. On SUN: SOLARIS.

14. OTHER PROGRAMMING OR OPERATING INFORMATION OR RESTRICTIONS

Before
compiling ETOBOX, the recommendations given in Appendix A.7 (page A.17) of the ETOBOX user's manual (PSI Bericht 96-02) should be taken into consideration.
