This takes around 6.000.000 years but it could take longer depending on the amount of nuclear fuel spilt.
Thousands of years at least
Spent nuclear fuel is typically stored on-site at nuclear power plants in steel and concrete containers called dry casks. Some countries have centralized storage facilities where spent fuel can be safely stored until a permanent disposal solution is developed. Long-term solutions may include deep geological repositories where the fuel is permanently isolated from the environment.
Uranium minerals support a long way of transformations to become sintered pellets of uranium dioxide, the most common nuclear fuel.
Recycling nuclear fuel does not eliminate the need for long term storage of spent fuel. Uranium fuel is routinely refined and recycled, but the process is messy, expensive and itself creates nuclear waste. Some long lived isotopes of fission will always need disposal somewhere.
Mostly the long lived radioactivity left in the spent fuel, but also any leakage from a damaged plant as at Fukushima.
Spent fuel rods from US nuclear reactors are typically stored on-site in specially designed pools or dry cask storage systems. The long-term storage solution, however, is to transfer the fuel rods to a geological repository, such as the proposed Yucca Mountain repository in Nevada.
Transporting spent nuclear fuel poses a greater environmental threat compared to transporting toxic chemicals, mainly due to the potential for radioactive contamination in case of a spill or accident. Spent nuclear fuel can have long-lasting environmental impacts and poses a risk to human health, whereas toxic chemicals are generally easier to contain and clean up in the event of a spill.

It is in just about every country. Mainly because people worry about safety, and what to do about the long life waste from spent fuel.
Nuclear energy generates radioactive waste in the form of spent nuclear fuel, which contains radioactive isotopes. This waste must be stored and managed properly due to its long-term hazardous nature.
The used fuel in a nuclear power plant is the nuclear fuel being discharged from the nuclear reactor after being irradiated during reactor operation. It is usually composed of trans-uranium heavy elements, a wide variety of fission products (that resulted from the nuclear fission processes in the nuclear reactor) and products of radioactive decay (produced before and after fuel discharge from the nuclear reactor).
