Abstract : The hydrodynamic loads due to a LOCA are computed with the CASTEM-PLEXUS code for a PWR primary circuit. An hydraulic model of the complete circuit (pipes, pumps, steam generators and reactor) is performed here assuming rigid pipes. CASTEM-PLEXUS being able to carry out FSI, the future work will take into account this effect.
