CFD SIMULATION OF SLOSHING PHENOMENA INDUCED BY SEISMIC EVENTS. APPLICATION TO ALFRED

The pathway towards the validation of the CFD simulation of sloshing phenomena induced by seismic events is illustrated. The aim of the work is to qualify the CFD for the simulation of seismic induced sloshing effects of the primary coolant in a GEN-IV reactor. The scaling laws have been established so that the CFD validation could be supported by experimental campaigns using the SHAKESPEARE platform. In the first stage, a partially filled vertical cylinder was employed for experimental tests and numerical simulations under horizontal harmonic forcing. In the second stage, a mock-up inspired by the current design of ALFRED is built and operated in water. The validity of the numerical model is ascertained by comparison with the experimental results performed on artificial harmonic forcing. Finally, the CFD model is run applying existing seismic loads taken from a real significant earthquake. Considerations on the impact load on internal structures foreseen in ALFRED are extrapolated.
