“…The FCI and MCCI have been studied experimentally in COTELS project as a joint study between NUPEC (Japan) and National Nuclear Center, NNC (Republic of Kazakhstan) using one of the testing complexes at NNC [37][38][39][40][41]. The testing complex includes three experimental facilities ''SLAVA,'' ''LAVA,'' and ''LAVA-M'' for debris coolability tests.…”

The Tohoku Region Pacific Coast Earthquake and subsequent severe accident (SA) in Fukushima Daiichi Nuclear Power Station caused unprecedented disaster in Japan. Before this accident, considerable researches on SAs had been carried out in Japan. However, unfortunately, such researches could not prevent the accident due to the unexpected huge Tsunami. However, the researches on SAs become more and more important in order to make clear the causes of the accident in Fukushima and improve the safety of nuclear power plants in Japan. In view of this, review on researches on thermal hydraulics in SAs in light water reactors was carried out. Important thermal-hydraulic phenomena in SAs were identified. Research activities on each phenomenon were surveyed mainly based on the articles published in Journal of Nuclear Science and Technology of Atomic Energy Society of Japan.

“…In other experiments as COTELS [23], the heat was injected to the metallic phase, due to other characteristics of their induction system. The VULCANO VBS tests have shown unexpected results regarding the metal oxidation during MCCI and the phase repartition that must be better understood, in order to determine how they can or not be present at a reactor scale.…”

“…• A liquid concrete slag layer with continuous material removal via gas bubbles instead of RT instabilities is assumed by Hassan (2000). • A porous aggregate layer is assumed in the contribution of Maruyama et al (2006), based on the COTELS experiments with basaltic concrete. It yields a thermal resistance for the concrete ablation (as the liquid slag layers in the above approaches).…”
