Description (excerpt):
Analytical codes and methods play a critical role in the design and safety analysis of nuclear reactors, helping to evaluate complex systems against potential severe events. This NEA report addresses the regulatory requirements for these tools and their application in reactor design and safety analysis.
Informed by a comprehensive survey of experts drawn from the NEA Working Group on the Safety of Advanced Reactors (WGSAR), the report highlights key areas such as verification, validation, and uncertainty estimation. It discusses differences in regulatory approaches, particularly in code certification and user qualifications, and the necessity for simulation tools to address Generation IV reactor-specific phenomena.
