Project VALVERDE – validation and verification of computational tools to describe corium spill to improve deterministic analyses of severe accidents

The VALVERDE project focuses on the investigation of the melt flow characteristics of the core melt simulant material and the subsequent development of suitable procedures and methodologies for the description of the melt flow of the simulant in a defined geometry. The main aim is to develop an experimental setup in which the melt spreading of the corium will be performed using suitable simulants. The current version of the experimental setup and the CFD simulations of the spreading of the reactor core melt simulant will be presented.
