|Abstract:||The development of innovative fast systems as defined by the Generation IV International Forum and selected by the Sustainable Nuclear Energy Technology Platform for Europe require increased R&D efforts for advanced neutronics simulation methods for core design and safety related analyses. The Strategic Research Agenda confirms that "Availability of accurate nuclear data ... is the basis for precise reactor calculations both for current and new generation reactors. Additional experimental measurements and their detailed analysis and interpretation are required in a broad range of neutron energies and materials. This is particularly true for fuels containing minor actinides for their transmutation in fast spectra." New developments in nuclear data are primarily driven by changes such as the trend towards increasing the burnup of nuclear fuel, and the use of new materials and fuel types. In most cases, the improvement of the accuracy of the existing nuclear data constitutes the main challenge. The available experimental database has been analysed carefully in view of the requirements for the development of advanced- and especially for fast- systems and priorities for improvements in the nuclear database have been set. In Europe, several facilities are still available where such measurements can be performed, operated in their majority by universities or national research centres. The maintenance, upgrade and continuous evolution of this research infrastructure is essential for providing the necessary support to the design of innovative reactors and associated fuel cycles. An additional, very important aspect is the availability of these technical installations for an effective training to the future generation of scientists in the nuclear energy domain. In this context, the European Commission has sponsored in the frame of the Euratom Framework Programme several projects dedicated to nuclear data measurements and evaluations, the development and validation of advanced codes for the modelling of nuclear reactions, and supported the access of European research groups to available facilities.|
