The Status of Generation IV Sodium-Cooled Fast Reactor Technology Development and its Future Project

Fast Breeder Reactors drastically improve uranium resource utilization efficiency to realize thousands of years of nuclear energy usage, by means of building up a nuclear fuel recycling system (FBR cycle). FBRs can also transmute extracted minor actinides.Recently, new worldwide concerns are focused on counter measures against long-term energy security and global environmental problems due to developments of the emerging countries, leading to new attentions on the FBR cycle. This paper provides the status of sodium-cooled fast reactor technology development and its future prospects.
