The CIELO collaboration has studied neutron cross sections on nuclides that significantly impact criticality in nuclear technologies – ¹⁶O, ⁵⁶Fe, ^235,8U and ²³⁹Pu – with the aim of improving the accuracy of the data and resolving previous discrepancies in our understanding. This multi-laboratory pilot project, coordinated via the OECD/NEA Working Party on Evaluation Cooperation (WPEC) Subgroup 40 with support also from the IAEA, has motivated experimental and theoretical work and led to suites of new evaluated libraries that accurately reflect measured data and also perform well in integral simulations of criticality.
