Research capability and technical expertise in the area of nuclear science are needed to maintain a high level of performance and safety of present nuclear installations, as well as to develop future-generation nuclear power programmes.

The NEA Nuclear Science Committee (NSC) has completed a study on future research and development needs in specific areas of nuclear science, covering nuclear data; reactor physics and systems behaviour; and reactor fuels, materials and coolants.

This report contains information on past and present international R&D activities conducted under the aegis of the NSC and on R&D needs for new nuclear systems in different NEA member countries. Recommendations for further work in the areas mentioned above are also given in the report. Possible follow-up actions to these recommendations will be considered by the NSC.
