我们描述了新的 ENDF/B-VIII.0 评估核反应数据库。 ENDF/B-VIII.0完全纳入新的原子能机构标准，包括改进的热中子散射数据，并使用本期《核数据表》配套文件中所述的H-1、O-16、Fe-56、U-235、U-238和Pu-239中子反应的CIELO项目的新评估数据。这些评估受益于最近在美国和欧洲获得的实验数据以及理论和模拟的改进。显着的进展包括轻核、结构材料、锕系元素、裂变能量释放、瞬发裂变中子和射线光谱、热中子散射数据和带电粒子反应的更新评估数据。针对各种临界性、反应速率和中子传输基准进行了整体验证测试。总体而言，该文库的整体验证性能相对于之前的ENDF/B-VII.1文库有所提高。
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 H-1, O-16, Fe-56, U-235, U-238 and Pu-239 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 ray spectra, thermal neutron scattering data, and 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.
