Abstract
With the ALISA Co-operation between the European Union and China on SA (Severe Accident) facilities, CGNPC (China General Nuclear Power Corporation) has proposed to CEA (Commissariat à l’Energie Atomique et aux Energies Alternatives) a series of experiments to determine physical properties of two corium compositions representative from Molten Core Concrete Interaction (MCCI): LOCA and LOOP. This article describes those tests performed on the two compositions in the VITI facility, by means of the Maximum Bubble Pressure (MBP) method. The measurement procedure using the Maximum Bubble Pressure method is described. Both density and surface tension measurements are successfully performed for both LOCA and LOOP corium compositions, which constitutes to our best knowledge the first measurements ever performed for ex-vessel (MCCI) liquid corium compositions.
