1. NAME AND TITLE OF DATA LIBRARY

KAOS/LIB-V: A Library of Nuclear Response Functions Generated by KAOS-V Code From ENDF/B-V and Other Data Files

2. NAME AND TITLE OF DATA RETRIEVAL PROGRAMS

RETRIEVE: An interactive program to retrieve selected responses and perform group collapsing from the VITAMIN-E 174-group values.

3. CONTRIBUTORS

Argonne National Laboratory, Argonne, Illinois.

4. HISTORICAL BACKGROUND AND INFORMATION

The microscopic cross section data bases provide the means of computing kerma factors for many materials and for incident neutron energies up to 20 MeV. The computed kerma factors from microscopic cross sections suffer from large uncertainties that cruelly manifest themselves as negative values. It is believed that improving the nuclear data files would solve the problem. However, the effort involved in doing so is massive. There is a need for improved methods in calculating nuclear heating parameters from existing data. The creation of KAOS/LIB-V is a response to this need.

5. APPLICATION OF THE DATA

The library is designed for fusion and fission applications.

6. SOURCE AND SCOPE OF DATA

The library includes neutron kerma factors, gas production, tritium breeding cross sections, and all important reaction cross sections for a large number of materials of interest in fission and fusion systems. The library was generated with the KAOS-V code (PSR-306) employing basic nuclear data from ENDF/B-V. Auxiliary nuclear data bases, such as the Japanese library JENDL-2, were used as a source of isotopic cross sections when these data are not provided in ENDF/B-V files for a natural element. KAOS/LIB-V employs the VITAMIN-E weighting function and energy group structure of 174 neutron groups.

7. DISCUSSION OF THE DATA RETRIEVAL PROGRAMS

RETRIEVE is an interactive program written in Fortran 77 to retrieve selected responses and perform group collapsing from the VITAMIN-E 174-group values.

8. DATA FORMAT AND COMPUTER

Card images; Cray computers.

9. TYPICAL RUNNING TIME

None noted.
