A new pointwise library for nuclear fission applications, named MCJEF22.BOLIB, was produced at the Nuclear Data Centre of ENEA-Bologna. The general features of this 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 JEF-2.2 evaluated data files and contains at the moment 98 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 JEF-2.2 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, MCJEF22.BOLIB can be applied also in cell and core calculations dedicated to the study of the subcritical accelerator driven systems (ADS).

Abstract
A new pointwise library for nuclear fission applications, named MCJEF22.BOLIB, was produced at the Nuclear Data Centre of ENEA-Bologna. The general features of this 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 JEF-2.2 evaluated data files and contains at the moment 98 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 JEF-2.2 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, MCJEF22.BOLIB can be applied also in cell and core calculations dedicated to the study of the subcritical accelerator driven systems (ADS).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
