my basement is more dangerous
In many parts of the country the native amount of radioactive elements in the ground is many times higher than what has happened there.
I live in Minnesota and the Radon gas concentrations in basements is an order of magnitude more dangerous that this stuff.
Having said that, I agree with BassRiverBill but add that plasma ovens convert all organic stuff and heterogeneous mixtures of diluted radioactive products. In the case of the diluted radioactive materials it glassifies them into a substance you can walk up to and lick it, it is so safe. It is so hard that eroding it is a millineal time issue. You also encase it in a skin to increase imperviousness.
It's not being done due to the constant roadblocks set up by the Chicken Little Society of American and its affilated chapters in Green Peace, WWF, etc. This is only an issue because they want it that way as fund raisers. The fuel rods can be recycled and about 75% to 90% reused except that Jimmy "What me worry?" Carter signed away our ability to do so. This would reduce the radioactive waste stream to nearly nothing in combination with the above.
Science fact is preferred over science fiction.
