In the US high level waste, ie spent fuel unloaded from reactors, is not disposed of, it is stored in water filled pools on the power station sites. In some cases the pools provided have been filled and above ground storage in shielded containers has been resorted to. A repository for long term storage has been proposed for Yucca Mountain Nevada, but no use has been made of this, and I believe there is no permission yet for transport of the material to Yucca Mountain, so that has to be part of the solution.

This problem will have to be solved eventually, especially as more nuclear stations are now to be built.

There must be storage places for low level waste arising at other locations - medical waste for example, but I have no information on these.

In the US a permanent storage site has been selected at Yucca Mountain, Nevada. Yucca Mountain is in an extremely dry area of Nevada. This minimizes the possibility of water seeping through the rock and corroding the casks. Additionally, if the casks do get corroded, there is not much water flow to carry the nuclear wastes away. The casks will be buried about 1500 feet underground, further preventing the waste from escaping. It is also far from the nearest population center in Las Vegas. While Yucca Mountain is near of a fault line, the fault is believed to be inactive. There are several volcanoes in the vicinity, but scientists believe that they have been dormant for almost a million years and think it unlikely that they will erupt in the next 10,000 years. Naturally, the people in Nevada are opposed to the creation of a nuclear waste repository. They express the common reaction, NIMBY (Not In My Backyard!!). This is because that although most evidence indicates that Yucca Mountain is a suitable place for storage, no one can guarantee that waste will not leak. However, quite a bit of research has already conducted around the Yucca site. Also, work on tunneling into the mountain has been started. The Yucca Mountain Deep Geological Repository is projected to be ready by the year 2010.

Yucca mountain was abandoned before it opened. There is no storage site.

Well, a few years ago I was a caretaker in a house across from a railroad switching-yard in Illinois. We'd occasionally see a kind of low railcar, like a roof on a flatbed, with a pill-box in the middle - painted all black w/a few safety yellow pipes & markings on it. I asked a friend, who worked for the rail line what it could be & was told 'rad-waste'. The transportation of nuclear waste is not a disposal method but a manner of conveyance to its place of disposal which is somewhere remote and underground. The only real disposal method at this time is "safe" storage in a remote location.

There are well established methods and approaches to dispose of radioactive nuclear waste based on the waste physical form (solid, liquid. gaseous) and the radioactivity level (low, intermediate, high).

Primarily; three methods are applied:

  1. Delay and decay: to maintain waste in tanks for some periods of time to allow decay of radioactivity and then to be disposed of to environment.
  2. Dilute and disperse: to dispose to environment (through dilution and dispersion) as ocean, sea, atmosphere, etc.
  3. Contain and concentrate: This is used mainly for high level radioactive waste as spent fuel or the spent fuel reprocessing products; either in wet storage, dry storage, or incineration&containment in barrels, or vitrified waste.

Most of it from commercial plants is stored on the same power plant sites where it is produced. There is no national repository yet.

Which country? If you mean the USA, it is mostly stored in water filled tanks on the various power station sites.

Noplace. The reactors just store it underwater in storage pools. They will run out of space eventually.

It is stored until the radioactivity depletes orif buried deep if there are high levels of radioactivity and buried shallow if there are low levels
