Analysis and Modelling of Severe Accidents for Liquid Metal Fast Reactors

In March 2023, the IAEA organized a Technical Meeting on the Safety Approach for Liquid Metal Cooled Fast Reactors [LMFRs] and the Analysis and Modelling of Severe Accidents. This publication summarizes the material that was presented during this meeting, related to the analysis and modelling of severe LMFR accidents. It covers knowledge on the physical phenomena and the development of models and numerical tools, and their validation through experimental data related to the progression of severe accidents. This publication is intended for public and private sector organizations developing LMFRs, research facilities, organizations responsible for designing LMFRs, operators and contractors, including prospective operators, and regulatory bodies.
