Abstract

A new version (April 1999) of the MCB6.BOLIB library for nuclear fission applications, produced at the Nuclear Data Centre of ENEA-Bologna, is presented. The general features of this pointwise neutron cross section library below 20 MeV, processed in ACE format for the MCNP Monte Carlo transport code with the NJOY-94.66 nuclear data processing system, are described. The library is based on the ENDF/B-VI Release 3 evaluated data files and contains at the moment 96 isotopes/natural elements including fission products, processed up to eight temperatures: 300 °K, 500 °K, 560 °K, 760 °K, 800 °K, 1000 °K, 1500 °K and 2200 °K. The processed data include gamma-production data when the basic ENDF/B-VI Release 3 evaluated data files contain these kind of data. The present library was satisfactorily tested in thermal and fast criticality benchmarks. For analyses below 20 MeV, MCB6.BOLIB can be applied also in cell and core calculations dedicated to the study of the subcritical accelerator driven systems (ADS).
