N2 - In the reactor pit of the European Pressurized Water
Reactor (EPR), a special kind of sacrificial concrete
type is used. The concrete is made of both siliceous
(SiO2) and hematite (Fe2O3) aggregates. There was very
scarce public experimental data about the behavior of
this special concrete type in a severe accident. In
co-operation with CEA, an experiment was conducted at the
VULCANO facility in Cadarache, France. This VB U7
experiment involved interaction between oxidic corium,
containing UO2 and ZrO2, and the hematite-containing
concrete. It was found out that the special concrete type
behaves in the same way as ordinary siliceous concrete
but differently from limestone-common-sand (LCS)
concrete.
