Hierarchical Structure of Safety Goals for Nuclear Installations

This publication discusses the development and application of a hierarchical structure of safety goals encompassing high level goals and detailed technical requirements that may assist in forming a coherent and consistent approach to nuclear safety. The suggested hierarchy of safety goals provides a practical approach to consistently embrace the set of safety-related requirements, both qualitative and quantitative, and develop the interconnections between them. Specifically, the structure supports adding country specific safety goals (e.g. risk metrics) to the overall safety considerations in a consistent manner. This process can be aided by reference to the IAEA Safety Standards.
