In-vessel loads resulting from molten fuel coolant/structure interactions
One of the objectives of the FARO project at JRC Ispra is to help determine the thermal and pressure loads on RPVs resulting from molten fuel coolant/structure interactions. Quantities from 3 to 150 kg of UO(2)-ZrO(2) melts are used in wet and dry conditions in the FARO (large scale) and KROTOS (small scale) facilities. The discharge of the melt from a degraded core to the lower plenum is simulated. The induced thermal load on the bottom is studied in FARO as a function of the height of water present in the lower head, which is varied from 0 (dry conditions) to 2 m. The quasi-static pressurisation of the vessel due to steam generation during melt/water quenching is measured. Dynamic pressure loading resulting from energetic FCIs are studied at small scale in KROTOS.
