The OECD NEA Working Group on Analysis and Management of Accidents (WGAMA) is responsible for activities related to potential accidental situations in nuclear power plants address the safety aspects of existing reactors and emerging safety challenges to enable safety design and operation of advanced nuclear technologies, including those for SMRs. The WGAMA objective is to assess and, where necessary, strengthen the technical basis needed for the prevention, mitigation and management of potential accidents in NPPs, and to facilitate international convergence on safety issues and accident management analyses and strategies. The achievements of WGAMA have been outstanding in preparing technical reports, becoming reference materials, and in organizing workshops and conferences to discuss innovative methods, materials and technologies in the fields of thermal-hydraulics (T/Hs), CFD and severe accidents. This paper aims to review and summarize the recent WGAMA activities and outcomes, as well as future perspectives, focusing on nuclear reactor T/Hs safety analysis in water cooled reactors and possible applications to advanced designs.
