Tokyo Electric Power Co. (TEPCO) admitted for the first time on May 15 that most of the fuel in one of its nuclear reactors at the Fukushima No. 1 Nuclear Power Plant had melted only about 16 hours after the March 11 earthquake struck a wide swath of northeastern Japan and triggered a devastating tsunami.
Based on provisional analysis of data on the reactor, the utility concluded that the water level in the pressure vessel began to drop rapidly immediately after the tsunami, and the top of the fuel began to be exposed above the water around 6 p.m. Around 7:30 p.m., the fuel was fully exposed above the water surface and overheated for more than 10 hours. At about 9 p.m., the temperature in the reactor core rose to 2,800 degrees Celsius, the melting point for fuel. At approximately 7:50 p.m., the upper part of the fuel started melting, and at around 6:50 a.m. on March 12, a meltdown occurred.
On the reason why it took over two months after the earthquake to reveal the information, TEPCO said it had only been able to start obtaining detailed data on the temperature and pressure in the reactor for analysis in early May.
"They could have assumed that when the loss of power made it impossible to cool down the reactor, it would soon lead to a meltdown of the core. TEPCO's persistent explanation that the damage to the fuel had been limited turned out to be wrong," he said.
They lost power so I understand why they couldn't get data immediately without power, but it seems like they had some power a week later so I would have thought they'd have data then, and moreover, they should have been able to predict what would happen to the exposed core, even without the data.

If they say so.
Very funny!

Well I guess that's alright then never would have seen that coming.
Japan nuclear crisis: Fukushima shutdown for January
Japan still believes it can end its nuclear crisis within months, while accepting damage from March's quake and tsunami was worse than first thought.
The government and the operator of the Fukushima Daiichi power plant recently revealed the No 1 reactor suffered a near complete meltdown within hours of the disaster.
Within 16 hours most of the fuel in reactor 1 had melted to the floor of the pressurised chamber housing the reactor, creating a hole that allowed 3,000 tonnes of contaminated water to leak into the basement of the building.
In a separate development, the operators of Japan's ageing Hamaoka nuclear plant south-west of Tokyo said all reactors were in a state of cold shutdown.
The plant is located in the Tokai region near a tectonic faultline just 200km from Tokyo, and Prime Minister Naoto Kan called for its closure in light of the catastrophic events at the Fukushima plant.
Here ya' go!

Actually some ATS guys figured it out before that,, and the proof is here as well,, just good luck finding it mostly because of this
