WheThrow the Nuclear Waste

Last I read, mass drivers had some problems in speeds over 2km/s due to the intertia of the magnetic fields. The power required to overcome this delay is sizeable and the amount of thrust you get at higher speeds diminishes. Lunar tethers in my view look to have some real potential for getting to and from the lunar surface. This removes the need for mass driversand expensive rocket fuel.

If we want to liberate of the Nuclear Waste, we can shoot it to the space with a mass driver. A Mass Driver build in Alaska, in the north of the mountains of the MacKinley Mountain, with 5 Km of long and the extreme pointing to the South. We can convert the nuclear waste in bricks of sand mixed with radiactive materials and a powder that flame with the Sun Light.
This brick, wrapped on a bag of plastic that degrade too with the Sun Light in 2 or 3 monts.
The brick, shooted out at 11 Km/s, go away, far, arround the Sun and when the Sun Light degrades the Bag, the brick is dissolved by the Sun Light and the powder go away, to the limits of the Solar System. Then, the cost of Throw the Nuclear Waste to Space will be very cheap. I Thing that the best source of energy will be the Solar Power Stations, in the future, but meanwhile, there is many nuclear centrals and the nuclear waste is a very important problem. This is, in my opinion, the only reason for building a mass driver in the Heart. I just have read the book The Moon is a Harsh Mistress, of Robert A. Heinlein, where he write about Mass Drivers for the transportation of PERSONS and Goods to the Moon. Wath do you thing about this?
