[3C01] Development of seismic counter measures against cliff edges for enhancement of comprehensive safety of nuclear power plants
Part6: Definition and representation of cliff edge
Keywords:Cliff edge, Defense in depth, Seismic behavior of plant, Seismic isolation, Human behavior
In this paper, we clearify the required performance of whole system of the nuclear power plant. Then, we identify and quantify the cliff edges related to them, and develop methods to avoid them. Define the physical cliff edge and knowledge-originated cliff edge, and apply the concept of defense in depth to the knowledge-originated cliff edge.
