A horrific grid. it compares the various nuclear meltdown scenarios. we had chernobyl. that was the worst. here's chernobyl, has the highest rating of seven. levels below that are at five, three mile island. the japanese officials are saying now the situation at fukushima right now, the one we're looking at is still a four. give us a sense of what that means. seven being chernobyl. five being three mile island. and the difference not in the meltdown degree but the level of successful containment, put those two figures together, meltdown, degree and containment. >> absolutely. so this is not go...

Turns the turbine. you cool it off, pump it back through here and cool down the reactor. rather than burning coal and remember wag the steam, well, you have a reactor core and control rods and pods here warming with you are rain yum inside a nuclear reactor. those rods are warming water to warm water, to warm steam, to warm a turbine, and it goes on and on. and as long as processes are working, everything works great. the problem is that it didn't work right, because when the earthquake happened, power got shut off. this was generating its own power. the power shutoff and backups came in. the ...

And ukraine's children noeshl plant. the water supply to the reactor was mistakenly closed. the core shut down but a series of human and instrument errors led to an overheating situation, similar to one we're seeing at fukushima. very little radiation escaped into the atmosphere. the chernobyl disaster in 1986 proves to be more devastating to the environment. ne technicians shut down the power regulating and safety systems, and removed most of the control rods from the reactor core. a chain reaction started leading to explosions and a fireball, and at fire in the reactor's core released larg...

Japan. i'm wolf blitzer, you're in "the i'm wolf blitzer, you're in "the situation room." -- captions by vitac -- www.vitac.com let's beginning with the breaking news right now at that nuclear power plant, a state of emergency is in effect for three reactors at these nuclear power facilities, the same place where an explosion today injured four people. as we said, there are conflicting reports about a meltdown in one of the reactors. a meltdown is a catastrophic failure of the reactor core with a polish for a widespread release of radiation. cnn's anna coren is in sendai, a port city closest...

Warming the air and you're being warmed by that air. if all of these closed systems work in a nuclear reactor, nothing goes wrong. here you go, the water comes in, it cools down this, this is part of a turbine, the turbine is turning, whether it's a coal-fired plant or not, the coal-fired plant warms water, water turns the steam, steam turns the turbine. you turn this down. cool it off. you pump it off and cool down the reactor. now, rather than burning coal and warming the steam, well, you've got a reactor core and you have control rods and you have pods here warming with uranium inside a nuc...
