Generation IV International Forum Risk and Safety Working Group – Onthe Safety of Generation IV Nuclear Systems

摘要

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