Events 1989 incident In January 1989, an impeller blade on one of the reactor coolant pumps in Unit 3 broke at a weld, causing a large amount of metal debris to flow throughout the primary loop. As a result, the reactor was shut down for a considerably long time.March 2011 2011 earthquake and tsunami The March 11, 2011 Tōhoku earthquake and tsunami|2011 Tōhoku earthquake resulted in maximum horizontal ground accelerations of 0.21 g (2.10 m/s2) to 0.28 (2.77 m/s2) at the plant site, which is well below the design basis. http://www.tepco.co.jp/en/press/corp-com/release/11040103-e.html The record of the earthquake intensity observed at Fukushima Daiichi Nuclear Power Station and Fukushima Daini Nuclear Power Station (Interim Report) TEPCO 1 April 2011 All four units were Scram|automatically shut down immediately after the earthquake, according to Nuclear Engineering International, and the diesel engines were started to power the reactor cooling.Insight to Fukushima engineering challenges http://www.world-nuclear-news.org/RS_Insight_to_Fukushima_engineering_challenges_1803112.html March 18, 2011 March 19, 2011 World Nuclear News TEPCO estimated that the tsunami that followed the earthquake and inundated the plant was 14 meters high which is more than twice the designed height. This flooded the pump rooms used for the essential service water system transferring heat to the sea, the ultimate heat sink of the reactors. While the cooling system for unit 3 was undamaged, the other reactors were affected. The cooling systems remained operational, but heated up due to the lack of a heat sink. The high pressure coolant injection (HPCI) system (powered by reactor steam) was used as additional cooling. On March 12, the Nuclear reactor technology|cooling system for three reactors (numbers 1, 2 and 4) at the torus had topped 100 °C between 05:30 and 06:10 Japan Standard Time|JST,reports for reactor 1, reactor 2, and reactor 4 of Tokyo Electric, received 11:50 JSTWinter, Michael "Cooling system fails at 3 reactors at another Japanese nuclear plant" USA Today, March 11, 2011, 6:01 EST. rendering all cooling systems (depending on temperature difference between the torus and the reactor) ineffective.

The coolant systems in the pump room were repaired and activated in Units 1, 2 and 4 in the days following the emergency shutdown after cooling could recommence Coolant temperatures below 100 °C (cold shutdown) were reached in reactor 2 about 34 hours after the emergency shut down (SCRAM).http://www.world-nuclear-news.org/RS_Cold_shutdowns_at_Fukushima_Daini_1403112.html Cold shutdowns at Fukushima Daini 2011 March 14 World Nuclear News March 14, 2011 Reactors 1 and 3 followed at 1:24 and 3:52 on March 14 and Reactor 4 at 7:00 on March 15.All Fukushima No.2 plant reactors safely halted http://www3.nhk.or.jp/daily/english/15_24.html Tuesday, March 15, 2011 11:58 +0900 (JST) March 15, 2011 The loss of cooling water at reactors 1, 2 and 4 was classified a level 3 on the International Nuclear Event Scale (serious incident) by Japanese authorities as of March 18.http://www.iaea.org/newscenter/news/tsunamiupdate01.html IAEA Update on Japan Earthquake Japanese authorities have assessed that the loss of cooling functions in the reactor Units 1, 2 and 4 of the Fukushima Daini nuclear power plant has also been rated as 3.
