We will review the events and status of the nuclear power plants that were affected by the "Great East Japan Earthquake" on March 11, 2011. Tsunami induced by the earthquake most severely affected three reactors of the Fukushima Daiichi power plant. Loss of all external and internal power sources interrupted the cooling of the reactors and resulted in melting of the reactor cores. Containment building failed in one of the reactors and the failure was followed by a release of large quantities of the radioactive materials between March 15 and 17. Key events will be reviewed in the affected reactors, performance of the existing temporary cooling systems and plans for the permanent cooling systems with closed water loops. Plans for restoration of the accident will be reviewed together with possible problems. Lecture will be concluded with analysis of the local and global consequences of the accident.
