it is a poison to humans. it is the smell that it is.
Spent nuclear fuel is radioactive, and it generates heat for a considerable period following removal from the reactor core. Storage in a pool of water keeps it cool.
You have a misapprehension there, it is uranium oxide that is used in fuel rods, not fossil fuel
Yes, that could be dangerous, especially if combined with or caused by a loss of coolant You are probably looking for either "nuclear meltdown" or "China Syndrome."
fuel rods
The fuel rods used in a nuclear reactor are made from uranium 235(U-235).
Because thats just the way it is!
Reactor fuels contain dangerous radioactive fission products after use, so the spent fuel rods must be carefully handled and stored.
Right now, the US stores spent fuel rods in spent fuel pools near the reactor, or in specially made storage vaults at each facility. We are working on facilities to store spent fuel, such as Yucca Mountain, but at this point, that is embroiled in controversy.
No, they are stored in pools of water.
Do you mean spent fuel? This term is used to describe fuel rods that have insufficient energy left.
In water filled tanks on the power station site
The high level waste, which is the dangerous part, is contained in the spent fuel, so it has the same volume as the fuel rods, unless they are processed. The actual amount is manageable, it is the high activity that is the problem for disposal.
During fission, the amount of fissionable isotope in each fuel rod decreases. Eventually there is no longer enough fuel in the rods to ensure that the output of the power station remains constant. The isotope-depleted, or spent, fuel rods must be removed and replaced with new fuel rods.Spent fuel rods are classified as high-level nuclear waste. They contain a mixture of highly radioactive isotopes, including both the fission products and what remains of the nuclear fuel.Some of these fission products have very short half-lives, on the order of fractions of seconds. Others have half-lives of hundreds or thousands of years. All nuclear power plants have holding tanks, or "swimming pools," for spent fuel rods.

The rods are actually made of crystal and are called stators. They do not come in contact with radiation and are not dangerous.
1 billion years
Used fuel rods need to be safely transported in order to prevent the release of radioactive material into the environment accidentally, and protected from vandalism or terrorists who may want to use it. Spent fuel must be stored in a place that is safe for people and secure from tampering.
