Genesis of Generation IV Concept q In 1999, low public and political support for nuclear energy • Oil and gas prices were low q USA proposed a bold initiative in 2000 • The vision was to leapfrog LWR technology and collaborate with international partners to share R&D on advanced nuclear systems • 9 Countries and EU joined USA in developing the initiative • Oil prices jumped soon thereafter q Gen IV concept defined via technology goals and legal framework • Technology Roadmap released in 2002 • 2 year study with more than 100 experts worldwide • Nearly 100 reactor designs evaluated and down selected to 6 most promising concepts • First signatures collected on Framework Agreement in 2005; first research projects defined in 2006 “This may have been the first time that the world came together to decide on a fission technology to develop together. ” ~William Magwood IV, First Chairman of the Generation IV International Forum
