The TENDL neutron data library and the TEND1038 38-group neutron constant system

The library contains neutron data for 103 nuclei - i.e. for 38 actinide nuclei (from sup 2 sup 3 sup 2 Th to sup 2 sup 4 sup 9 Cm), 26 fission fragment nuclei and 39 nuclei in structural and technological materials. The 38-group constants were obtained from TENDL. The high-energy group boundary is 2...

Sumario:The library contains neutron data for 103 nuclei - i.e. for 38 actinide nuclei (from sup 2 sup 3 sup 2 Th to sup 2 sup 4 sup 9 Cm), 26 fission fragment nuclei and 39 nuclei in structural and technological materials. The 38-group constants were obtained from TENDL. The high-energy group boundary is 20 MeV. The energy range below 1.2 eV contains 11 groups. Temperature and resonance effects were taken into account. The delayed neutron parameters for 6 groups and the yields of 40 fission fragments were obtained (light and heavy, stable and non-stable). The fast neutron features of spherical critical assemblies were calculated using constants from TEND1038.
