There are MANY solutions to the problem of nuclear waste (shooting it into
the sun, encasing it in molten glass and dumping it into the ocean, pumping
it into salt domes, shipping it to Nigeria, etc.). The reason none of these
has been implemented is because there is no need to choose one. We'll simply
wait until the need is urgent.

The longer we wait, the greater the chance an even better solution will
become clear.

No, the silliness of the anti-nuclear crowd, "We have no solution for the
waste", is a red herring.

nearly every option has large downside potential.

like shoot into deep space or sun, what of launch failures

breeder reactor reprocessing has issues of its own

any of these choices have astronomical costs involved,

since japan designs tto take into account problems uncovered will make
nuke power too expensive to use
