Abstract

New version of the evaluated neutron data library BROND-3.1 are compiled that includes 372 files for isotopes from hydrogen to curium and the incident neutron energies from the thermal one up to 20 MeV. Main features of the included evaluations are briefly discussed attracting particular attention to uncertainties of evaluated data. The full scale verification of the library is performed on the basis of the optimal set of international benchmark experiments on neutron transmission and criticality safety. Uncertainties of the benchmark simulations are in the range of experimental uncertainties for the majority cases.

Keywords
neutron reactions, evaluated data, reactor materials, uncertainty covariance maticies

Data library BROND-3.1 is available here.
