Abstract

This chapter discusses the assurance of safety, which is particularly important for nuclear power plants. This becomes a design constraint and requires additional functions. This chapter first presents an overview of the basics of safety assurance for all nuclear reactors and then discusses the characteristics of the FR and the basic policies for assuring safety. It specifically describes the handling of core fuel possessing nuclear characteristics differing from that used in light-water reactors, safety measures for plants using sodium, and severe accident measures.

Fußnoten

“IP” is the early phase of a core damage and meltdown process, where the wrapper tube of each fuel assembly maintains the essential integrity and molten core materials move only in the axial direction within the wrapper tubes. When the “IP” does not lead to significant power rise due to prompt criticality, gradual melting of wrapper tubes subsequently causes the mutual movement of molten core materials among fuel assemblies, eventually resulting in a condition where the reactivity changes due to the whole core motion. The subsequent process is referred to as “TP.”
