Timeline Back-up generator of reactor nr. 1 flooded On 30 October 1991 one of two backup generators of reactor nr. 1 did fail, after it was flooded in the basement of the reactor buildings. Seawater used for the cooling of the reactor was leaking into the turbine-building from a corroded pipe at a rate of 20 cubic meters per hour. This was told by former TEPCO employees to the Japan Broadcasting Corporation news-service in December 2011.

Consequently those generators ceased working and the pumps that circulate coolant water in the reactor ceased to work, causing the reactors to begin to overheat. The flooding and earthquake damage hindered external assistance.
