User requirements and approaches of development for future nuclear energy system

Technology innovation is one of the key issues in every field for the future of the technology. In early 21st century, international nuclear society has a common recognition on the necessity of innovative nuclear energy system to cope with new trend and increasing energy demand, several international programs were initiated for development of new systems that secure stable energy supply and have improved public acceptance, safety, and cost-effectiveness. This paper surveyed status of international activities on future innovative nuclear energy systems, and describes the user requirements of future nuclear energy system for the deployment in the future. The approaches to development of the innovative nuclear energy technologies for meeting future goals were discussed
