Tokyo Electric Power Co, the operator of the Fukushima Daiichi nuclear power plant disabled by the March 11 earthquake and tsunami, confirmed on Tuesday that there had been meltdowns of fuel rods at three of the plant’s reactors early in the crisis.
The government and experts said previously that fuel rods at three of Daiichi’s six reactors had likely melted early in the crisis, but the utility, also known as Tepco, had only confirmed a meltdown of fuel rods at the No. 1 reactor.
On Tuesday, Tepco officials announced that fuel rods had also melted at the plant’s No. 2 and No. 3 reactors.
Explaining the timing of the announcement, a Tepco official told a news conference that the utility had been gradually retrieving data from the plant since early May, and had analyzed it before reaching a conclusion.
