Abstract : The mechanical consequences of a steam explosion on a PWR lower plenum vessel are estimated through a parametric study regarding the corium location, the kinetics to transfer the corium energy to the water and the water constitutive law.
Keywords : steam explosion PWR lower plenum vessel corium water Europlexus
