Generation IV International Forum Risk and Safety Working Group - On the Safety of Generation IV Nuclear Systems

摘要

The Generation IV International Forum (GIF) Risk and Safety Working Group (RSWG) was created to promote a homogeneous and effective approach to assuring the safety of Generation IV nuclear energy systems. The six Generation IV reactor concepts that have been selected by the GIF members, potentially present a diverse set of design and safety issues. A number of these issues differ significantly from those presented by the earlier generations of light water reactors. The overall success of the Generation IV program depends on the ability to develop, demonstrate, and deploy advanced system designs that exhibit excellent safety characteristics. While the RSWG recognizes the excellent safety record of nuclear power plants currently operating in GIF member countries, it believes that advanced technologies and a coherent safety approach hold the promise of making Generation IV energy systems even safer and more transparent than this current generation of plants. The RSWG believes that an important key to meeting the safety goals set forth in the Generation IV Technology Roadmap document lies in the formulation and early application of a coherent safety philosophy in which safety is "built in, not added on" to the basic designs of nuclear systems.
