Uncertainties and covariances for inelastic scattering data : a status report

In the present report we collect several contributions concerning the correctness, uncertainties and covariances of data obtained with the Germanium Array for Inelastic Neutron Scattering (GAINS) which is installed at the GELINA neutron time-of-flight facility. Both inelastic scattering cross sections and uncertainties and covariances for nuclear data are of great current interest as they feature prominently in uncertainty estimates for key parameters of reactor systems [3]. It is for this reason that a task of the European Collaborative Project Accurate Nuclear Data for nuclear Energy Sustainability (ANDES) is devoted to uncertainties and covariances of inelastic scattering data obtained with GAINS. This report is written in evidence of a milestone (M1.6) of that project. It also provides evidence for a deliverable (6.04) of the work programme 2011 of Action 51402 Nuclear data for radioactive waste management and safety of new reactor developments (ND MINWASTE) of the JRCIRMM.
