At 2:46PM on March 11th 2011, the turbines and reactors of Fukushima
Daiichi Nuclear Power Station Unit 1 (Boiling Water Reactor, rated output
460 Megawatts) and Units 2 and 3 (Boiling Water Reactor, Rated Output 784
Megawatts) that had been operating at rated power automatically shutdown
due to the Tohoku-Chihou-Taiheiyou-Oki Earthquake.
In response, water injection into Unit 2's reactor were being carried out
by the Reactor Core Isolation Cooling System. However, as the Reactor Core
Isolation Cooling System failed today, it was determined that a specific
incident (failure of reactor cooling function) stipulated in article 15,
clause 1 has occurred at 1:25 pm today.
