|Abstract:||The objectives of SARNET2 FP7 are to define and work on common research programs in the field of severe accidents in Gen.II-III nuclear power plants (NPP) and to further develop common tools and methodologies for safety assessment in this area. Ensuring that the research conducted on severe accidents is efficient and well-focused, the Severe Accident Research Priority (SARP) work performed in SARNET FP6 is being updated by evaluating the most recent experimental results and taking into account the remaining safety issues as e.g. highlighted by Level 2 PSA studies and the results of the recent EU-ASAMPSA2 Project. These evaluation activities are conducted in close relation with the work performed under the auspices of international organizations like OECD or IAEA. The severe accidents in Fukushima, which occurred while SARNET2 was running, had some effects on the prioritization and definition of new research topics. Although significant progress has been gained and simulation models (e.g. ASTEC integral code) are improved, leading to an increased confidence in the predictive capabilities needed for assessing the success potential of countermeasures and/or mitigation measures, most of the selected research topics are still of high priority. Notably after the Fukushima’s accident, research to improve SAM efficiency was seen as necessary. The final status of the SARP work conducted within SARNET2 FP7 will be presented.|
