Digital. you know how you put the photo, or may have seen it in a movie, somebody working with an actual -- with actual film and developing chemicals in an actual dark room. put the photo in the developer until the image comes in like you want it, then once it is in that, you put it in a different chemical bath to stop the developing. that's like the control rods. they stop the chain reaction. but the fuel rods, those pellets of uranium inside big metal straws, even when the reactor is turned off, they are still wicked hot. even though the reactor is off and not being used to boil water to mak...

Chris was talking about. they are gripping the hardest-hit regions of japan. two reactors are in partially meltdown and fuel rods in a third exposed. multiple systems to prevent that have failed. this is how it happened courtesy of japanese national television. >> control rods rose into the reactor to stop the nuclear fission. as planned, the reactor stopped operating. but the fuel rods were still hot. water should have been circulated to cool them down. however, this didn't happen because of a power outage right after the quake. so the second safety system turned on. the emergency diesel powe...

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. that's 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 are involved in a nuclear chain reaction generating heat. when they shut off the reactor in the normal course ...

I don't know if you ever had the chance to develop a photo in a dark room before everything went digital. you know how you put the photo, or may have seen it in a movie, somebody working with an actual -- with actual film and developing chemicals in an actual dark room. put the photo in the developer until the image comes in like you want it, then once it is in that, you put it in a different chemical bath to stop the developing. that's like the control rods. they stop the chain reaction. but the fuel rods, those pellets of uranium inside big metal straws, even when the reactor is turned off, ...
