Evaluations of neutron nuclear data for medium-heavy nuclides were performed for JENDL-3.3. The present work was undertaken to remove the drawbacks of the previous library JENDL-3.2. Recent measurements and nuclear model calculations were taken into account to improve the accuracy of the evaluated data. The data on natural elements were not produced in order to solve a problem of the inconsistency between elemental and isotopic data except for carbon and vanadium in JENDL-3.3.

Times Cited Count：669 Percentile：96.97(Nuclear Science & Technology)Evaluation for JENDL-3.3 has been performed by considering the accumulated feedback information and various benchmark tests of the previous library JENDL-3.2. The major problems of the JENDL-3.2 data were solved by the new library: overestimation of criticality values for thermal fission reactors was improved by the modifications of fission cross sections and fission neutron spectra for 
U; incorrect energy distributions of secondary neutrons from important heavy nuclides were replaced with statistical model calculations; the inconsistency between elemental and isotopic evaluations was removed for medium-heavy nuclides. Moreover, covariance data were provided for 20 nuclides. The reliability of JENDL-3.3 was investigated by the benchmark analyses on reactor and shielding performances. The results of the analyses indicate that JENDL-3.3 predicts various reactor and shielding characteristics better than JENDL-3.2.
