Work to Continue at Japan Plant Despite Release of Meltdown Details, Hiroko Tabuchi for The New York Times, May 17, 2011:
[... TEPCO] now acknowledges that a fuel meltdown occurred at three of the plant’s six reactors in the early hours of the crisis, something experts had been suggesting for weeks. [...]
Tokyo Electric in the past week has released data that show that the fuel rods at the three most damaged reactors started to melt down rapidly after the site was jolted by a quake at 2:46 p.m. on March 11 [...]
[A]n uncontrolled meltdown had begun, as fuel started to slump to the bottom of the reactor pressure vessel. [...]
The company says meltdown also happened at Reactors No. 2 and 3. [...]
Meltdowns also likely occurred at No. 2, No. 3 reactors of Fukushima plant, Asahi Shimbun, May 18, 2011:
[Fumiya Tanabe, a former senior researcher at what was then the government-affiliated Japan Atomic Energy Research Institute] said black smoke from the No. 3 reactor building in the days after the earthquake and available data on pressure showed early on that a meltdown had taken place.
