The ENEA-Bologna Nuc1ear Data Centre produced the VITJEF22.BOLIB multigroup coupled (199 n + 42 gamma) cross section library in AMPX format, based on the JEF-2.2 European nuclear data file. The generation of the VITJEF22.BOLIB library for nuclear fission applications was conceived as an European counterpart of the VITAMIN-B6 American library, based on the ENDF/B-VI Release 3 nuc1ear data file. The present library has the same group structure and general features as VITAMIN-B6 and was produced using the same data processing methodologies, based on the NJOY-94.66 and SCAMPI data processing systems. VITJEF22.BOLIB is a pseudo-problem-independent library based on the Bondarenko (f-factor) method for the treatment of neutral resonance self-shielding and temperature effects. The library contains 133 nuclides processed at 4 temperatures (300 °K, 600 °K, 1000 °K and 2100 °K), obtained for the most part with 6 to 8 values for the background cross section. Thermal scattering cross sections were processed at all temperatures available in the JEF-2.2 thermal scattering law data file for 5 additional bound nuc1ides (H-1 in light water, H-1 in polyethylene, H-2 in heavy water, C in graphite and Be in beryllium metal). From VITJEF22.BOLIB it is possible to generate, through further proper data processing with the AMPX or SCAMPI systems, collapsed working libraries of self-shielded cross sections in AMPX or FIDO format. VITJEF22.BOLIB was extensively tested on many thermal and fast criticality benchmark experiments.
