[en] Evaluations of most physical observables are based on a statistical analysis of a compilation of experimental data, model calculations and their uncertainties, heavily biased toward the former for observables with sufficient experimental data. Hence, as new experimental data become available, they are incorporated into the evaluation files. The latest LANL measurements at LANSCE of the neutron capture on ^234,236,238U, as well as measurements of the fission cross section ratio to ²³⁵U for both ²³⁴U and ²³⁶U have prompted the re-evaluation of all the reactions channels for these reactions. In the case of ²³⁹Pu, the evaluation of the prompt fission neutron spectrum (PFNS) is updated based on LANSCE measurements by the Chi-Nu collaboration. In addition to discussing the evaluation of the minor U isotopes, we give an update of the PFNS evaluation, as well as latest cross section evaluations for neutron induced reactions on ²³⁹Pu.
