Summary:

The book 'Assessment of Defence in Depth for Nuclear Power Plants' by the International Atomic Energy Agency provides a comprehensive analysis of the concept of defence in depth as applied to nuclear power plants. It outlines the evolution of this safety philosophy, which involves multiple levels of protection to prevent and mitigate accidents. The publication revises earlier guidelines to incorporate recent advancements in safety requirements and practical experiences. The book presents an updated assessment method using objective trees to evaluate nuclear power plants' adherence to defence in depth principles. It is primarily intended for operating organizations, regulatory bodies, and technical support organizations, offering guidance on ensuring safety throughout a plant's lifecycle from siting to decommissioning. The book emphasizes the importance of maintaining safety functions through various safety provisions, including design features, operational procedures, and safety culture. Generated by AI.
