Rachel. >> let me know first, i guess, if i got anything wrong there, if i got anything important wrong there or left anything important out. i am obviously a layman, trying to understand this for myself as well as make it understandable for viewers. >> it was a solid and accurate description of where we are today. >> okay. within the last couple hours, as i mentioned, a third explosion was reported at fukushima number 2 reactor. number 1 had explosion this weekend, number 3 did 24 hours ago. an...

They are creating a nuclear reactor to generate heat. the whole point of nuclear power is that you create an environment in which fission happens. a nuclear chain reaction happens, but it is controlled, so it does not produce an explosion. it just generates heat in a controlled way instead. use that heat to essentially boil water. actually, you literally use it to boil water. boiling water makes steam, steam spins a turbine, and that makes electricity. thats the basic idea behind the 40-year-old...

There already have been other explosions at one reactor this morning and another at another reactor on saturday. each time there is an explosion there is release of radioactivity that is why there is a 12 mile exclusion zone, 140,000 people have been evacuated and some have been exposed to radiation and the folk here, the authorities say it is under control but there are a lot of skeptical people here in japan and elsewhere. >>shepard: in question, greg, we know there are millions facing difficu...

How significant is it? and how significant is it on a wider level that weve now seen three of these in the last few days? >> well, piers, its a little difficult to tell. weve seen three of them because when you have a reactor that isnt cooled properly, the steam interacts with the metal surrounding the fuel rod and that gives off hydrogen. and the hydrogen will explode pretty easily. the other two explosions were in the outer building. this explosion happened within the primary containment. and ...

That the metal on the long metal tubes oxidizes. when it breaks down, it splits. damage to the fuel rods is a partial nuclear meltdown. one of the things that is released into the air at the water level drops and the fuel rods get exposed to the air and the big metal straws start to oxidize, one of the gases is hydrogen, and it is explosive. they believe hydrogen explosion caused this to happen at one of the reactors friday night, daytime saturday japan time. monday morning, japan time, second r...

Happens. a nuclear chain reaction happens, but it is controlled, so it does not produce an explosion. it just generates heat in a controlled way instead. use that heat to essentially boil water. actually, you literally use it to boil water. boiling water makes steam, steam spins a turbine, and that makes electricity. thats the basic idea behind the 40-year-old reactors in japan in so much trouble now. when the reactor is on, in effect, the uranium pellets inside the big 12 foot long fuel rods ar...
