Power failure hits Fukushima plant in Japan

A power failure at Japan's tsunami-hit Fukushima nuclear plant has been partially fixed, operator Tepco says.

The outage hit the pumps controlling the cooling system for the ponds at reactors 1, 3 and 4, although cooling to the reactors themselves was not affected.

Cooling has now been restored to the pool at reactor 1, with cooling at the reactor 3 and 4 pools expected to resume on Tuesday evening.
