An accurate estimation of the radioactive release following a severe accident is required to determine the risks associated with operating nuclear power plants. The evaluation of this radioactive source term has been improved by research results and the development of the corresponding new models. Among new phenomena, revaporization seems to play a substantial role in the process, mainly after vessel failure, when it can dominate the long term release. Analysis of the revaporization phenomenology lacks a good understanding of the various events taking place, for example the chemical interaction of vapours with surfaces and aerosol particles, the radiation and disintegration effects and the detailed coupling between revaporization and thermal-hydraulics. This state-of-the art report serves as a guideline to assess previous research efforts and to propose further analyses.
