Feasibility of an experimental program on the corium retention issue for ALWR plantsFunded under: JRC-REACTSAFE 6C
In order to verify the acceptability of corium cooling-retention strategies, a feasibility study has been undertaken to design a new experimental rig starting from the existing FARO facility at JRC-Ispra. These new tests, using prototypical corium and sustained heating, aim to verify the material behaviour of test plates representative of corium retention structures at the expected temperatures, the existence of unknown chemical reactions, and the effective heat transfer coefficients between the different phases and components. The key features to be investigated are test plate material resistance to corium jet impacts and long-term ablation, the downward heat transfer inhibition caused by lower corium crust formation, and the effect of flooding on debris quenching.
