Advanced power reactors with improved safety characteristics

Research output: Contribution to journalArticlepeer-review


The primary objective of nuclear safety is the protection of individuals, society and environment against radiological hazards from accidental releases of radioactive materials contained in nuclear reactors. At a worldwide scale, several advanced reactor concepts are currently being considered, some of them already at a design stage. Essential safety objectives include both further strengthening the prevention of accidents and improving the containment of fission products should an accident occur. Two typical approaches can be distinguished:. The first approach basically aims at an evolution of power reactors currently in use, taking into account the findings from safety research and from operation of current plants. The second approach consists in more fundamental changes compared to present designs, often with strong emphasis on specific passive features protecting the fuel and fuel cladding barriers. The paper describes the basic objectives of such developments and illustrates important technical concepts focusing on next generation plants, i.e. designs to be available for industrial application until the end of this decade.
