title: Generation and validation of a shielding library based on ENDF/B-VI.8.
abstract: For various shielding and reactor pressure vessel dosimetry applications, a pseudo-problem-independent neutron-photon coupled MATXS-format library, based on the last release of ENDF/B-VI, has been generated as a part of the update program for KASHIL-E6, which was based on ENDF/B-VI.5. It has a VITAMIN-B6 neutron and photon energy group structures, i.e. 199 groups for the neutron and 42 groups for the photon. The neutron and photon weighting functions and the Legendre orders of scattering are the same as in KASHIL-E6. The library has been validated through some benchmarks: the PCA-REPLICA and NESDIP-2 experiments for the light-water reactor (LWR) pressure vessel facility benchmark, the Winfrith Iron 88 experiment for the validation of the iron data and the Winfrith Graphite experiment for the validation of the graphite data. These calculations were performed by the TRANSX/DANTSYS code system. In addition, the substitutions of the JENDL-3.3 and JEFF-3.0 data for Fe, Cr, Cu and Ni, which are very important nuclides for shielding analyses, were investigated to estimate the effects on the benchmark calculation results.
