The operator of the Fukushima nuclear power plant in Japan says there might have been partial meltdowns in its No. 2 and 3 reactors from damage after the earthquake and tsunami in March.
The latest announcement means all three reactors with active fuel inside the Fukushima plant, north-east...
A meltdown occurred at one of the reactors at the Fukushima No. 1 Nuclear Power Plant three and a half hours after its cooling system started malfunctioning, according to the result of a simulation using "severe accident" analyzing software developed by the Idaho National Laboratory.

No one knew it was leaking until a worker found it on May 11. The amount of radioactive materials in the leaking water was far less than the pit water gushing from the Reactor 2 back in early April.
Reactor 3 uses MOX fuel.

There must be a large leak," Junichi Matsumoto, a general manager at the utility also known as Tepco, told a news conference on Thursday.
"The fuel pellets likely melted and fell, and in the process may have damaged ... the pressure vessel itself and created a hole," he added.
Since the...
New evidence suggests that nuclear chain reactions at the Fukushima power plant didn't end when the generators were initially shut down, following the March 11 earthquake.
Technology Review explains why Tetsuo Matsui, a researcher at the University of Tokyo, thinks conditions inside two of...
