“…The main uncertainties in the core degradation area concern corium behaviour in the reactor lower head and cooling of debris beds, as concluded in the current review of research priorities (Klein-Heßling et al, 2013), which were not specifically addressed in the experiments summarised here. These issues were and will be tackled on a cooperative basis as was the case in the SARNET project for example (Albiol et al, 2010;Van Dorsselaere et al, 2011), indeed the separate-effects experiments outlined here benefited from such cooperation, for example regarding air ingress and boron carbide (Haste et al, 2012) interactions.…”

“…The source term program in SARNET is now being developed, based on PIRT established by EURSAFE to reduce the uncertainties of the release and transport behaviour of FPs and actinides [49]. This program covers the following phenomena: effect of oxidative conditions on FPs, especially Ru; release and transport behaviour under an air ingress scenario; volatility of I in the primary circuit; control rod aerosol release (Ag-In-Cd) that affects I transport; aerosol retention in containment cracks; aerosol remobilization in the primary circuit [50]; and I and Ru behaviour in the containment, especially concerning the volatile fraction in the atmosphere [51].…”

We have launched a new research program for evaluation of fission product and actinide release behaviour under severe accident conditions, focusing on their chemical forms. In this research program, the fission product and actinide release models incorporated in the severe accident analysis code will be improved by implementing effects of chemical forms that are to be obtained by an experimental investigation on the fission product and actinide release behaviour from irradiated fuels. A novel insitu measurement method of chemical forms of fission products and actinides just after their release as well as an off-line analysis method will be employed as the experimental means for evaluating the chemical forms at the release and their stability after release.

“…For that objective, it is still necessary to reduce further the uncertainties on some phenomena and on simulation modelling. A review and update of the highest priorities was performed in 2012-2013 by the SARP (Severe Accident Research Priorities) group of ad-hoc experts (Klein-Hessling et al, 2014), led by GRS. Its work was based on the analysis of R&D progress in the last years, on national PSA2 results and on the conclusions of the ASAMPSA2 FP7 project (2013), and accounted for the impact of the FukushimaDaiichi accidents.…”

The SARNET network (Severe Accident Research NETwork of excellence), co-funded by the European Commission from 2004 to 2013, has allowed to significantly improve the knowledge on severe accidents and to disseminate it through courses and ERMSAR conferences. The major investigated topics, involving more than 250 researchers from 22 countries, were in- and ex-vessel corium/debris coolability, molten-core–concrete-interaction, steam explosion, hydrogen combustion and mitigation in containment, impact of oxidising conditions on source term, and iodine chemistry. The ranking of the high priority issues was updated to account for the results of recent international research and for the impact of Fukushima nuclear accidents in Japan. In addition, the ASTEC integral code was further developed to capitalize the new knowledge. The network has reached self-sustainability by integration in mid-2013 into the NUGENIA Association. The main activities and outcomes of the network are presented
