Tepco Cut Backup Power at Fukushima Before Crisis, Sankei Says

Don't Miss Out —
Follow us on:

Jan. 19 (Bloomberg) -- Tokyo Electric Power Co. disconnected an emergency power source at its Fukushima nuclear plant four months before the earthquake and tsunami in March last year wrecked the station, the Sankei newspaper said.

The supply was cut during maintenance work in November 2010 and wasn’t reconnected, the paper reported, without citing the source of its information.

The backup would have provided power for transmitting temperature and radiation data from monitors near the Fukushima Dai-Ichi plant’s reactors and helped assess the severity of the situation once the main electricity supply was knocked out, the Sankei said.

Tokyo Electric is checking the Sankei report and can’t immediately comment, spokeswoman Ai Tanaka said.
