Abstract
- For the validation of the recently released evaluated nuclear data files JEF-2 and ENDF/B-VI a first set of benchmark calculations for thermal systems important for criticality safety and LWR-neutronics were performed and compared with corresponding calculations based on JEF-1 and the MCNP-3B library (ENDF/B-IV, ENDL-85). The processing of the JEF-2 and ENDF/B-VI data which are given in the ENDF-6 format was performed by an updated version of the nuclear data processing system NJOY. Both multigroup libraries with 316 groups in MATXS-format and MCNP-libraries (continuous data with a very fine energy resolution) based on JEF-2 and ENDF /B-VI were generated. The ORNL uranyl nitrate benchmarks as well as the PNL Pu nitrate benchmarks were analysed by deterministic (ANISN/ONEDANT-S N -method) and Monte Carlo methods (MCNP-3B). The group constants for the S N -calculations were generated by a combination of TRAMIX and RSYST/CGM.
