Severe ACcident REsearch group

The severe accident research group is active in:

Own experimental work

  • Filtered containment venting systems (FCVS)
  • Two-phase flow hydrodynamics in the TRISTAN facility
  • Reflux condensation in the presence of non-condensable gases

Analytical work for source term analysis

Plant analysis using severe accident codes

  • Long-term station black-out (SBO) scenarios and the accident mitigation
  • Fukushima accident analysis: OECD/NEA BSAF project
  • Safety features of Molten Salt Fast Reactors (SAMOFAR)
  • Spent fuel pool (SFP) analysis
  • Assessment of MELCOR code
  • Coordination of European MELCOR user group (EMUG) meetings

Model development for severe accident codes

  • Project Air oxidation modeling includes:
    • enhanced oxidation under influence of Nitrogen
    • low temperature breakaway of oxide crusts w and w/o influence of Nitrogen
