Disposing of nuclear waste under Earth's crust

This may perhaps belong in a Geology forum but here goes.

Can anyone comment on the possibility of pushing nuclear wastes into the
molten magma below earth's crust? I belive someplace near the Mojave
desert in the US the earth's crust is only 4 or 5 miles thick.

I'm thinking that this would:
1) Perhaps greatly dilute the waste through a huge volume of viscous fluid
2) Confine it for enormous periods of time

This idea has been suggested already. The waste would be dropped into the rifts in the ocean, however, not on land.

What would happen if the stuff gets into a nearby volcano? You could get a dirty radioactive cloud!

mathman,

I think the subduction zones are far enough away, and sub-mantle
transport of material is slow enough; such that by the time the waste
reaches an active volcano - the residual radioactivity is neglible.

Why bother? Dump the stuff in a geologically stable pit far below, and distant from the nearest water table, and forget about it.
