Generation, Validation, and Testing of a Coupled 219-Group Neutron 36-Group gamma-ray AMPX-2 Library.

摘要

The main characteristics of a P coupled 219-group neutron 36-group gamma-ray AMPX-2 Master Interface Format library, obtained by processing ENDF/B-4 data with various AMPX-2 System modules, are presented in this paper both for the reprocessing aspects and features of the generated component files - neutron, photon and secondary gamma-ray production cross sections. As far as the neutron data are concerned, there is the availability of 186 data sets regarding the most significant fission products. Results, pertaining to eighteen benchmark experiments, of the additional validation of the neutron data are also given. Some calculation tests, on both neutron and coupled data, emphasize the important role of the secondary gamma ray data in nuclear and criticality safety calculations.
