Summary of details at Fukushima Nuclear Stations and other reactors by Japan's Nuclear and Industrial Safety Agency:

Around 14: 07 April 12th, 2011, an earthquake occurred at the inland areas of Hamadori, Fukushima Prefecture.

All units of Onagawa Nuclear Power Station (NPS) (Tohoku Electric Power Company Inc.), Fukushima Dai-ichi NPS, Fukushima Dai-ni NPS (Tokyo Electric Power Company Inc.), and Tokai Dai-ni NPS (Japan Atomic Power Company Inc.) have been shut down since the Tohoku District - off the Pacific Ocean Earthquake occurred on March 11th, 2011.

The current situation of each nuclear facility is as follows:

Onagawa

All the external power lines are currently secured except for one power line that is under repair. The cooling function of the reactor and the Spent Fuel Pool are also secured.

Fukushima Dai-ichi NPS

External power supplies are secured and the fresh water is injected to each Unit without any irregularities by each pump. There are no unusual data measured at monitoring posts. Workers at the site were once directed to evacuate to the seismic isolated building but the direction was lifted later.

Fukushima Dai-ni NPS

The external power supplies are secured. There are no unusual data found in plant parameters. There are no unusual data measured at monitoring posts. Workers at the site were once directed to evacuate to the seismic isolated building but the direction was lifted later.

Tokai Dai-ni NPP

The 2 out of 3 external power supply lines are in operation. (1 line is currently under the Periodic Inspection.) The insulator of one of the power supply line in operation was replaced from 21:19 April 12th, and recovered at 03:15 April 13th. 3 Emergency Diesel Generators are ready and waiting. The cooling function of the reactor and the Spent Fuel Pool are secured. There are no unusual data measured at monitoring post.

No unusual events have been confirmed at the nuclear fuel fabricating facility and other facilities of Incorporated Administrative Agency, Japan Atomic Energy Agency located in Ibaraki Prefecture.
