All the significant high level waste is contained in the spent fuel, and will stay there when the fuel is stored after unloading, unless the fuel is taken to a plant designed for dismantling and separating it. This is done in the UK and France, possibly Russia, I'm not sure about that, but not in the US, not for commercial reactors anyway. The fissile part of the new fuel is about 4 percent U-235 and it is discharged with about 1 percent remaining so that difference determines the percentage of fission products in the discharged fuel. It will also contain plutonium which has been formed from the U-238 which forms 96 percent of the new fuel, but again a lot of the fissile plutonium formed will have been burned up during reactor operation. So the percentage by weight is a fairly small part of the spent fuel, most of which will be U-238, which if separated out is fairly inocuous and could be used in breeder reactors if we had any.
nuclear waste is a by product of nuclear power plants, or in the creation of nuclear weapons.
fear of the waste.
Heat.
In the US they're stored on site.
Nuclear Fission
Most of it does, but some comes from weapons manufacture as well
The honest answer is the USA has been producing a great deal of nuclear waste and ignoring the problem of what to do with it. President Obama wants more nuclear power plants, but, has not said what to do with nuclear waste. A lot of waste is stored in nuclear power plants, but, they are getting filled up fast, and that is not really a good idea. The possibility of an accident or theft is very real.

The waste is the issue.
The problem of disposing large amounts of nuclear waste is not resolved.
It contains a higher amount of radioactivity
