  • We describe the new ENDF/B-VIII.0 evaluated nuclear reaction data library. ENDF/B-VIII.0 fully incorporates the new IAEA standards, includes improved thermal neutron scattering data and uses new evaluated data from the CIELO project for neutron reactions on 1H, 16O, 56Fe, 235U, 238U and 239Pu described in companion papers in the present issue of Nuclear Data Sheets. The evaluations benefit from recent experimental data obtained in the U.S. and Europe, and improvements in theory and simulation. Notable advances include updated evaluated data for light nuclei, structural materials, actinides, fission energy release, prompt fission neutron and γ-ray spectra, thermal neutron scattering data, andmore » charged-particle reactions. Integral validation testing is shown for a wide range of criticality, reaction rate, and neutron transmission benchmarks. In general, integral validation performance of the library is improved relative to the previous ENDF/B-VII.1 library.« less

  • Comparisons of the measured neutron and gamma-ray spectra from silicon, copper, titanium, tantalum, tungsten, and lead bombarded with 14-MeV neutrons and calculations carried with the ENDFB/V (Evaluated Nuclear Data File) library have shown discrepancies. The ENDF/B-VI version of the Brookhaven National Laboratory neutron photon library is scheduled to be released in the near future. Because this version will not include revisions for all the above materials, the use must be aware of the problems to be expected.
  • The WIMS-D4M code has been chosen by the Reduced Enrichment for Research and Test Reactor (RERTR) Program for all future research reactor cross-section generation replacing EPRI-CELL. A new 69-group 96-material library has been created for use in WIMS-D4M. The latest SUN version of NJOY (91.27) was used to generate the ENDF/B-V-based cross-section library. The library also includes ENDF/B-V based fission yields, energy fission and energy per capture data. The upper energy boundary has been extended from 10 to 20 MeV in order to model high energy neutron reactions. Additional fuel and moderator temperatures have been included to better predict temperaturemore » coefficients. More excess potential scattering points have been added to increase the accuracy of self-shielded resonance cross-sections. Several benchmark comparisons have been made to validate the new library.« less
