  2. OECD/NEA WPEC Subgroup 26 Final Report: "Uncertainty and Target Accuracy Assessment for Innovative Systems Using Recent Covariance Data Evaluations", M Salvatores (coordinator), R. Jacquemin (monitor), Tech. Rep. NEA No. 6410 (2008). The request for improved cross sections and emission spectra and their accuracies for neutron induced reactions on 238U is an important issue that emerges in several of cases studied. High accuracy requirements were placed on inelastic cross-sections 238U(n,inl) in the whole energy range up to 20 MeV … Roberto Capote, IAEA Nuclear Data Section e-mail: R.CapoteNoy@iaea.org / Roberto.Capote@yahoo.com

  17. CONCLUSIONS • Existing state-of-the-art coupled-channels neutron OMPs provide CN formation cross sections with small uncertainty (~3%) for En>4 MeV, more work needed for lower energies; • improved neutron emission spectra (MSD+MSC) allow calculating the neutron inelastic scattering to the continuum; • current evaluations of neutron inelastic scattering to be revised.
