According to the recent publications of the European Technological Platform for a Sustainable Nuclear Energy (SNETP) (Vision report and Strategic Research Agenda) the sustainability require the combination of the present LWR, future Advanced Fast reactors and the waste minimization in closed cycles with Partitioning and Transmutation. To implement these new nuclear systems and their fuel cycles it is necessary to improve the accuracy, uncertainties and validation of related nuclear data and models, required for those systems but also for the experimental and demonstration facilities involved in the their validation. The project will include new nuclear data measurements, dedicated benchmarks, based on integral experiments, and improved evaluation and modeling specifically oriented to obtain high precision nuclear data for the major actinides present in advanced reactor fuels, to reduce uncertainties in new isotopes in closed cycles with waste minimisation and to better assess the uncertainties and correlations in their evaluation.
