Optimization of Protection Against External Hazards for Advanced Reactors

Objectives: The overall objective is to develop a methodology for grading that takes into account the safety features of the nuclear installation. (1) Technology neutral safety framework for assessing the applicability of site evaluation requirements considering site installation interactions, and (2) Propose a methodology for an overall optimization of the safety measures against external hazards supporting effective and balanced implementation of the defence in depth. The proposed framework is supported by a risk informed and performance based approach and application of a graded approach considering the advanced safety and mitigation features of the installation.
