Fukushima’s high nuclear reactor radiation a problem for melted fuel
"During recent investigations conducted using cameras and robots at the site of Fukushima No. 1 nuclear power plant, after six years of the triple meltdown, it has likely identified melted fuel rods for the first time underneath the damaged reactor 2, Japan Times reported. Following a major earthquake on March 11, 2011, a 15-metre tsunami disabled the power supply and cooling of three Fukushima Daiichi reactors, causing a nuclear accident."
