In the KRITZ-2 critical experiments, criticality and pin power distributions were measured at room temperature and high temperature (about 245 degree C) for three different cores loading slightly enriched UO or MOX fuels. For nuclear data testing, benchmark analysis was carried out with a continuous-energy Monte Carlo code MVP and its four nuclear data libraries based on JENDL-3.2, JENDL-3.3, JEF-2.2 and ENDF/B-VI.8. As a result, fairly good agreements with the experimental data were obtained with any libraries for the pin power distributions. However, the JENDL-3.3 and ENDF/B-VI.8 give under-prediction of criticality and too negative isothermal temperature coefficients for slightly enriched UO cores, while the older nuclear data JENDL-3.2 and JEF-2.2 give rather good agreements with the experimental data. From the detailed study with an infinite unit cell model, it was found that the differences among the libraries are mainly due to the different fission cross section of U-235 in the energy rage below 1.0 eV.

The under prediction of k depending on U enrichment in low enriched uranium fueled systems was studied in this report. Benchmark testing was carried out with several evaluated nuclear data files, including the new uranium evaluations from preliminary ENDF/B-VII and CENDL-3.1. Another problem reviewed here was k underestimation vs. temperature increase, which was observed in the slightly enriched system with recent JENDL and ENDF/B uranium evaluations. Through the substitute analysis of nuclear data of U and U, we propose a new evaluation of U data to solve both of the problems. The new evaluation was tested for various uranium fueled systems including low or highly enriched metal and solution benchmarks in the ICSBEP handbook. As a result, it was found that the combination of the new evaluation of U and the U data from the preliminary ENDF/B-VII gives quite good results for most of benchmark problems.

In recent years, intermediate energy nuclear data are required for various applications such as accelerator-driven systems for waste transmutation, spallation neutron sources, advanced cancer therapies, estimation of single event up set rate and dose on astronauts. For these requirements, many groups in the world continue intermediate energy nuclear data evaluation. The early stage of this evaluation was initiated in USA. For example, Pearlstein at Brookhaven National Laboratory produced systematics, modified ALICE code and evaluated proton and neutron nuclear data in late 1980s. At Lawrence Livermore National Laboratory, similar data developed for a medical application. Following them, many countries, such as Europe, Japan, Russia, China, Korea, started the preparation of nuclear data in this energy region. Overview of evaluation methods, results of evaluations are presented in comparison between experimental data and evaluated files, mainly JENDL High Energy File, as well as results from benchmark calculations.

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.
