The International Ministerial Conference on Nuclear Energy in the 21st Century provided an opportunity to review the status and prospects of nuclear power, and to discuss the actions necessary to carry forward the positive momentum that nuclear power has experienced in recent years. It also offered a forum for countries considering the potential benefits of introducing nuclear power into their national energy mix to further assess the viability of the nuclear power option. Conference participants discussed developments and emerging issues relevant to the role of nuclear power in providing clear and sustainable energy for national and regional development. The technical sessions were devoted to energy resources and the environment; available technology and long term perspectives; infrastructure development and safety and legal issues; and reliable fuel supply, spent fuel, waste management and strengthening of non-proliferation.
