The Technical Area N°2 “Severe accidents / SARNET” continues to be very active since severe accidents in Gen.II-III-III+ nuclear power plants are still a major R&D subject in a post-Fukushima accidents context. Six technical general issues are addressed: in-vessel corium/debris coolability, ex-vessel corium interactions and coolability, containment behaviour including hydrogen risk, source term released to the environment, impact of severe accidents on the environment and emergency management, and severe accident scenarios. The presentation will summarize the current activities of diverse types: - Periodic technical workshops: one on corium behaviour will take place mid-April during 1 week, - ERMSAR international conferences every 2 years: the last one in April 2017, hosted by NCBJ in Warsaw (Poland) was a big success and the next one in March 2019 will be hosted by UJV in Prague (Czech Republic), - Education and training courses on SA phenomenology and management: the last one, hosted by JSI in Ljubljana (Slovenia), was a success with 60 participants, and a course is under preparation in China, - Periodic ranking of R&D priorities by the SARP group composed of experts from 16 organizations, the last exercise at end of 2017 being used as basis for the current update of the NUGENIA roadmap. In addition several R&D “in-kind” projects were launched without external funding, thus based on partners’ own resources and competencies. They will be shortly described: CORE-SOAR on the update of the state-of-the art on core degradation, QUESA on code interpretation of air ingress experiments from SAFEST FP7 project, IPRESCA on pool scrubbing process of retention of fission products, and recently ASCOM on mutualisation of R&D on the ASTEC IRSN integral code. Maintaining all these activities at their current level in the future is essential for sharing the knowledge, maintaining the competencies, training new researchers in the domain, and improving the severe accident management guidelines.

Abstract
The Technical Area N°2 “Severe accidents / SARNET” continues to be very active since severe accidents in Gen.II-III-III+ nuclear power plants are still a major R&D subject in a post-Fukushima accidents context. Six technical general issues are addressed: in-vessel corium/debris coolability, ex-vessel corium interactions and coolability, containment behaviour including hydrogen risk, source term released to the environment, impact of severe accidents on the environment and emergency management, and severe accident scenarios. The presentation will summarize the current activities of diverse types: - Periodic technical workshops: one on corium behaviour will take place mid-April during 1 week, - ERMSAR international conferences every 2 years: the last one in April 2017, hosted by NCBJ in Warsaw (Poland) was a big success and the next one in March 2019 will be hosted by UJV in Prague (Czech Republic), - Education and training courses on SA phenomenology and management: the last one, hosted by JSI in Ljubljana (Slovenia), was a success with 60 participants, and a course is under preparation in China, - Periodic ranking of R&D priorities by the SARP group composed of experts from 16 organizations, the last exercise at end of 2017 being used as basis for the current update of the NUGENIA roadmap. In addition several R&D “in-kind” projects were launched without external funding, thus based on partners’ own resources and competencies. They will be shortly described: CORE-SOAR on the update of the state-of-the art on core degradation, QUESA on code interpretation of air ingress experiments from SAFEST FP7 project, IPRESCA on pool scrubbing process of retention of fission products, and recently ASCOM on mutualisation of R&D on the ASTEC IRSN integral code.
