A preliminary testing of the BUGENDF70.BOLIB library was performed through three-dimensional fixed source transport calculations with the TORT-3.2 discrete ordinates (Sn) code on the PCA-Replica 12/13 and VENUS-3 engineering neutron shielding benchmark experiments, specifically conceived to check the nuclear data and transport codes used in LWR radiation shielding and radiation damage analyses.

Abstract

The ENEA-Bologna Nuclear Data Group generated a broad-group coupled neutron and photon working cross section library in FIDO-A NIS format, dedicated to LWR shielding and pressure vessel dosimetry applications. This library, named BUGENDF70.BOLIB, was obtained in the neutron and photon energy group structures (47 n + 20 y) of the ORNL BUGLE-96 similar library and it is based on the US ENDF/B- VII.0 library of evaluated nuclear data. BUGENDF70.BOLIB was produced through cross section collapsing of the ENEA-Bologna VITENDF70.BOLIB general-purpose library in AMPX format for nuclear fission applications using the updated and corrected ENEA-Bologna 2007 Revision of the ORNL SCAMPI nuclear data processing system. This library, based on the Bondarenko (f-factor) neutron resonance self-shielding method, has the same neutron and photon energy group structures (199 n + 42 y) as the ORNL VITAMIN-B6 library in AMPX format (based on ENDF/B-VI.3 evaluated nuclear data) from which the BUGLE-96 library was generated at ORNL. A preliminary testing of the BUGENDF70.BOLIB library was performed through three-dimensional fixed source transport calculations with the TORT-3.2 discrete ordinates (Sn) code on the PCA-Replica 12/13 and VENUS-3 engineering neutron shielding benchmark experiments, specifically conceived to check the nuclear data and transport codes used in LWR radiation shielding and radiation damage analyses.
