Japan's plant admits partial meltdowns
The operator of Japan's tsunami-hit Fukushima nuclear power plant yesterday said it believed fuel had partially melted inside three reactors, as long suspected by experts.
Tokyo Electric Power Company (TEPCO) said new readings on water gauges indicated that the fuel had dropped to the bottom of the containment vessels of units two and three, matching its earlier assessment of unit one.
In all three reactors, relatively low temperatures indicated that the fuel was now mostly covered by water that has been pumped into the vessels, meaning there was no immediate threat of an uncontrolled full meltdown.
