“…A great deal of work was performed within the framework of the international experimental program on the ThAI (Thermal Hydraulics, Aerosols and Iodine) facility in Germany [119] and in the earlier DEMONA experiments [120], discussed in [121]. The flow circulation in the containment atmosphere plays an important role because it controls the transport and distribution of steam, other noncondensable gases or vapors, and aerosols.…”

ZrO 2 from cladding oxidation can also play a role in reducing the melting temperature of the corium mixture, as also discussed in [5].

“…Severity of consequences depends largely on the melt release states from RPY. Major processes constituting various ex-vessel phenomena are containment thermohydraulics, fission products transport, and melt dispersion [1,[7][8][9][10][11][12][13][14][15][16][17][20][21][22].…”

Containment threats during severe accidents may arise due to fuel coolant interactions, hydrogen combustion, molten core-concrete interactions, and long-term pressure and temperature loading. The objective of the paper is to bring out important issues in the assessment of containment integrity during severe accidents for PWR and PHWR. The issues are identified by extensive review and synthesis of information from literature on severe accident phenomena, severe accident analysis and containment integrity assessment.
