Nuclear and Industrial Safety Agency Ministry of Economy, Trade and Industry on August 12, the first nuclear power plant damaged by earthquake Toukyoudenryoku Hukuzima East (town Ookuma Fukushima Futaba town) in Unit 1, soluble in hot fuel rods "meltdown" has occurred likely announced.
According to NISA, No. 1 around the detection of radioactive cesium on NIRS team. Cesium is contained in nuclear fuel rods, because of its high melting point, it is estimated that the likely cause meltdown.
Japanese nuclear authorities said that there was a high possibility that nuclear fuel rods at a reactor at Tokyo Electric Power's Daiichi plant may be melting or have melted, Jiji news agency reported on Saturday.

The plant's operator, the Tokyo Electric Power Company, tells AFP: "We believe the reactor is not melting down or cracking. We are trying to raise the water level."
Without enough power for cooling systems, decay heat from the reactor cores of units 1, 2 and 3 has gradually reduced coolant water levels through evaporation. The consequent increase in pressure in the coolant circuit can be managed via pressure release valves. However, this leads to an increase in pressure within the reactor building containment. Tepco has said that the pressure within the containment of Fukushima Daiichi 1 has reached around 840 kPa, compared to reference levels of 400 kPa.
The company has decided to manage this "for those units that cannot confirm certain levels of water injection" by means of a controlled release of air and water vapour to the atmosphere. Because this water has been through the reactor core, this would inevitably mean a certain release of radiation. The International Atomic Energy Agency said this would be filtered to retain radiation within the containment.
However, the company's monitoring of Fukushima Daiichi 1 has separately shown an increase in radiation levels detected emerging from the plant via routes such as the exhaust stack and the discharge canal.
Over the last several hours evacuation orders for local residents have been incrementally increased and now cover people living within ten kilometres of the power plant.

URGENT: Concerns of core partially melting at Fukushima nuke plant
The core at Fukushima No. 1 nuclear power plant's No. 1 reactor may be partially melting, the nuclear safety agency said Saturday.
Radioactive substance cesium was detected around the reactor, it said.

I found those videos of japans last nuclear meltdown on wikileaks. I guess it was a different one. Monju.
