The objective of the Corium Interactions and Thermochemistry provect (CIT) is the experimental and computational modelling of corium properties and thermochemistry governing the in and ex-vessel progression of corium during a severe accident. These corium characteristics significantly affect melt formation and progression up to vessel failure and ex-vessel melt coolability and retention. The project includes the performance of different separate effect experiments, the development of a corium thermodynamic database corium modelling and the evaluation of corium uncertainties on plant calculations. Significant experimental and analytical results have already been produced on corium interactions, thermochemical database modelling.These results induced strong interactions with other projects of the Reactor Safety programme.
