Japan's nuclear reactors, at least the number one, two and three reactors at the Fukushima 1 Nuclear Power Plant, havefailed. These reactors were operating when the earthquake hit, and, though they shut down after the quake, the tsunami that followed knocked out power and the emergency generators at the plants. The cores in these reactors continued to generate what is called decay heat, and now they have suffered a meltdown.
The meltdown of the three reactors at the ÅŒkuma facility has now resulted in the distribution of highly radioactive materials across a broad area. Radiation levels are still fairly low a few tens of miles from the plant, but there is still no end in sight as regards reactivating any cooling systems. It remains to be seen if bringing electricity back to power up the site will allow for cooling systems to be activated. It may be that the blasts (probably caused by hydrogen gas) or the fires damaged the systems and they will not be able to be brought back online.

What happen if you fail?
You absolutely fail and you get an "F"
Why did chernobyl blow up but three mile island didn't?
The reason Chernobyl failed is because the plans used to design the plant were old and out of date. The technology was years behind. Where as Three Mile Island has multiple fail safes. All nuclear reactors have these. If something fails they have a fail safe to stop it, and if that fails there is another; and so on and so on. Three Mile has 4 fail safes, two of which failed and the third caught it preventing disaster.
Why would uranium be chosen as an alternative energy source?
Uranium had three advantages over other nuclear fuel, and several disadvantage. The potential other fuel was thorium. A comparison of the two systems includes:Uranium reactors are simpler than thorium reactorsThe byproducts of the uranium reaction (plutonium) can be used to make nuclear weapons.Uranium is rare and rapidly becomes a limited resource while thorium is common and virtually unlimited. The US had access to uranium through its own reserves and Canada.Thorium reactors "fail safe" if there is a problem, the nuclear reaction stops and the reactor becomes cold and inert. Uranium creates ongoing problems when they have an uncontrolled failure
What does the term melt down refers during a nuclear disaster?
The term melt down is a fairly literal description of what can happen when the cooling systems of a nuclear reactor fail; the reactor core becomes so hot that the whole thing literally melts into a puddle of radioactive slag.

you fail
What was the worlds worse nuclear accident that ever happen and in what country?
I use to work in a power station and the worlds worst nuclear accident happened at Chernobyl in the Ukraine only about 25 years ago it happen when they tried to run a power plant on a fail safe system that went horribly wrong by one of the pumps fail to pump water into the reactor and the level went down and exposed the nuclear rods which heated up and melted through the vessel and created super heated steam and exploded they've contained the building in concrete and lead. And nothing will be able to go near there for about 3000 years
What Henry Fonda film depicts an accidental nuclear war?
Fail-Safe
Would unmaintained nuclear weapons explode?
probably not, there are many parts that can fail

you will have to do role procution
