Possible Nuclear Meltdown in Fukushima


The possibility of a meltdown in progress exists at Fukushima Daiichi, Reactor 1.


The Nuclear and Industrial Safety Agency at the Ministry of Economy, Trade and Industry held a press conference on 3/12/11 at at 2:00 pm and announced that the nuclear reactor fuel in the Tokyo Electric Power Fukushima Daiichi Nuclear Power Station Unit 1 (Ookuma City, Fukushima Prefecture), may be in the process of melting down.


The National Institute of Radiological Sciences confirmed the presence of Cesium fission product in the nuclear fuel.


The water level of fuel A in Unit 1 dropped from -90 cm to -170 cm, and fuel rods appear to be exposed above the surface of the water.  It was confirmed that the water level of fuel B has gone from -80 cm to -145 cm.  Containment pressure is 750 kPa, but at 754 kPa, the pressure is relatively stable.


Among all hypothetical nuclear incidents, a meltdown is the worst. If this continues, it could end up causing an explosive reaction, spreading radiation outside the reactor.
