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 …

“Trust is the greatest incentive. If trust is missing, everything is missing.”[Maria Theresia
(1717–1780), Empress of Austria] If nuclear data users do not trust the data provided by data …

The nuclear fission process gives rise to the formation of fission fragments and emission of
particles (n,γ,e^-). The particle emission from fragments can be prompt and delayed. We …

Although the prompt fission neutron spectrum (PFNS) is an essential component of neutron-
driven systems that has been measured for decades, there are still multiple glaring …

In this paper, we provide templates of uncertainty sources expected to appear for three
measurement types of prompt fission neutron spectra (PFNS):(1) shape measurements,(2) …

With the recent emergence of fast nuclear reactors, there has been a corresponding
increasing interest in U 238-related nuclear data. However, while existing literature data …

Evaluations of nuclear reaction data for the major uranium isotopes 238 U and 235 U were
performed within the scope of the CIELO Project on the initiative of the OECD/NEA Data …

New prompt fission neutron spectrum measurements are reported for 235 U (n, f) reactions
induced by neutrons with energies from 0.7 to 20 MeV. These measurements cover outgoing …

The characterization of fission-driven nuclear systems primarily relies on calculations of
neutron-induced chain reactions, and these calculations require evaluated nuclear data as …

The physical properties of neutrons emitted from neutron-induced fission are fundamental to
our understanding of nuclear fission. However, while state-of-the-art fission models still …
