Since whatever they've told us about the Fukushima plant has only been part of the story, I wonder if this means No. 4 (the one that's leaning -- remember, the cat's on the roof!) is melting down as we speak:

Tokyo (CNN) -- Japan's Fukushima Daiichi nuclear power plant experienced full meltdowns at three reactors in the wake of an earthquake and tsunami in March, the country's Nuclear Emergency Response Headquarters said Monday.

The nuclear group's new evaluation, released Monday, goes further than previous statements in describing the extent of the damage caused by an earthquake and tsunami on March 11.

The announcement will not change plans for how to stabilize the Fukushima Daiichi plant, the agency said.

Reactors 1, 2 and 3 experienced a full meltdown, it said.
