Abstract

The question arising in several industries, in particular in foundries, paper mills, and nuclear industry is what happens if two liquids mix and the temperature of the first liquid is higher than the boiling temperature of the second one. The consequence of such a mixing can be a steam explosion. A strong enough steam explosion in the nuclear power plant could jeopardize the containment integrity and so lead to a direct release of radioactive material to the environment. The purpose of the research project is to develop a steam explosion model, which will be suited for modelling all four phases of a steam explosion (premixing, triggering, propagation, expansion) and will help finding answers on open questions regarding steam explosion understanding and modelling. Modelling of steam explosions is a challenging task, since a steam explosion is a complex coupled multi-component, multi-phase, multi-space-scale and multi-time-scale phenomenon. With the developed steam explosion model a number of steam explosion experiments will be analysed. Areas where better models are needed will be identified and better models proposed. Areas where more experimental data would be needed for better steam explosion understanding and model development will be identified and required experiments will be proposed. A proposal for the EU-sponsored free transnational access to the PLINIUS Corium platform at CEA, France will be prepared to perform in the KROTOS facility the most required steam explosion experiment with prototypic corium. The research project will be part of the 6.FP EU Network of Excellence SARNET (European Network on Water Reactor Severe Accident Research and Management) working programme, where also fuel-coolant interaction activities are planned.
