For the above 3 units, off-site power was lost due to malfunction of one
out of two off-site power systems, leading to automatic startup of

malfunction resulting in the complete loss of alternating current for all
three units.
Hence, at 3:42PM, it was decided that a specific incident stipulated in
Article 10, Clause 1 of the Act on Special Measures Concerning Nuclear
Emergency Preparedness has occurred and a "First Level Emergency" was
declared and in accordance with the aforementioned Act, the Minister of
Economy, Trade, and Industry, the Governor of Fukushima Prefecture, the
Mayor of Okuma Town, and the Mayor of Futaba Town along with other
involved organizations were notified of the incident.
