Current status of research at JAEA is presented for the development and application of methodologies to evaluate source term and ex-vessel debris coolability under wet cavity conditions in a severe accident of a light water reactor. The methodologies include simulation codes such as THALES2 for source term, KICHE for iodine chemical reaction kinetics in a containment vessel, CHEMKEq for fission product chemistry in a reactor cooling system and JASMINE for molten core/coolant interaction.
