“…Many research activities have been carried out in analytical and experimental researches in universities, research institutes, and industries. Surveillance on SA researches has been carried out in many research committees such as ''Special Research Committee on Thermal Hydraulic of Severe Accidents'' (Atomic Energy Society of Japan, AESJ) [1], ''Research Committee on Severe Accident'' (AESJ), ''IVR-AM (In Vessel Retention-Accident Management) Research Committee'' (Nuclear Power Engineering Corporation, NUPEC), Severe Accident Research Committee, Reactor Safety Research Committee (Japan Atomic Energy Research Institute, JAERI), and ''Advisory Committee on Severe Accident'' (Japan Nuclear Energy Safety Organization, JNES). International conferences and meetings on SA were held in Japan by AESJ, NUPEC, JNES, and other institutes (e.g., ''Technical Meeting on Severe Accident and Accident Management for Nuclear Power Plants,'' 14-16 March 2006, Tokyo, Japan, and ''SARJ (Workshop on Severe Accident Research, Japan), '' 1990-1999).…”

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.
