Freeze nuclear waste? Yep.

Turns out it decays WAY faster when you cool it to super-low temperatures.
Professor Claus Rolfs, leader of the group at Ruhr University in Bochum, Germany, said “The method we are proposing means that nuclear waste could probably be dealt with entirely within the lifetimes of the people that produce it. We would not have to put it underground and let our great-great-grandchildren pay the price for our high standard of living.”

The technique involves embedding the nuclear waste in a metal and cooling it to ultra-low temperatures. This speeds up the rate of decay of the radioactive materials potentially cutting their half lives by a factor of 100 or more.
