A new suite of evaluations for Fe-54,Fe-56,Fe-57,Fe-58 has been developed in the framework of the CIELO international collaboration. New resolved resonance ranges were evaluated for Fe-54 and Fe-57, while modifications were applied to resonances in Fe-56. The low energy part of the Fe-56 file is almost totally based on measurements. At higher energies in Fe-56 and in the whole fast neutron range for minor isotopes the evaluation consists of model predictions carefully adjusted to available experimental data. We also make use of the high quality and well experimentally-constrained dosimetry evaluations from the IRDFF library. Special attention was dedicated to the elastic angular distributions, which were found to affect results of the integral benchmarking. The new set of iron evaluations was developed in concert with other CIELO evaluations and they were tested together in the integral experiments before being adopted for the ENDF/B-VIII.0 library.
