The Independent, Mar. 6, 2013: Engineers can still only estimate the precise location of the nuclear fuel that melted through the containment vessels of three reactors.
The Commons (Vermont), Mar. 6, 2013: The reactors lost external power to cool their cores, and three have melted down, most likely beneath their containment vessels, although no one knows for sure, even two years later.
Huffington Post, Mar. 5, 2013: Fukushma Unit 1 began to meltdown as a result of the earthquake, before the tsunami hit and destroyed all backup power. The molten core of the reactor would melt through the reactor vessel and containment, crashing into the water below the reactor and sending radioactive steam surging out of the damaged building.
