ZZ MICROX 2 FSS LIB, Data Library for Fast Spectrum Systems Analysis

1 - Description: MICROX-2 data libraries for fast spectrum systems analysis, including accelerator driven systems (ADS). It is structured into three parts: FDTAPE contains fine group dilution- and temperature-dependent cross sections for the fast energy range, GGTAPE contains infinite dilution cross sections for the fast and thermal energy range, the fast data section not being needed in the current version of MICROX-2. GARTAPE contains point-wise Doppler-broadened resonance cross sections in the resolved energy range. 2 - Methods: Group- and point-wise data files from NJOY (Edition 89.62) have been edited into the FDTAPE, GGTAPE and GARTAPE input files for MICROX-2 using the PSI coupling module MICROR. The data libraries have been generated from data in 193 groups as well as from point-wise cross sections from NJOY (Edition 89.62), using the PSI coupling module MICROR. The FDTAPE data set includes self-shielded cross sections up to P3. Individual fission spectra are included. The thermal part of the GGTAPE consists of 101 energies and includes scattering matrices for the main moderators. The GARTAPE file contains point-wise, Doppler-broadened resonance cross sections in the resolved resonance range. It has been generated on the basis of equidistant velocity spacing. Data are tabulated for 24362 energy points between 2 eV and 8.0072 keV
