Well, right now, it actually costs more to dispose of nuclear waste than it does to buy the fuel, and run a nuclear reactor. To dispose of 1 cubic metre of low level waste (rubber gloves and paper towels etc... that have less activity than the tritium in your watch) costs more than $15,000 US. Even decommissioning a nuclear reactor is extremely expensive. If you want to lauch nuclear waste into space, then be prepared to pay 20x more on your energy bill? Are you nuts? There's a reason why astronauts are only allowed one luggage and one carry on 
At least it is a permanent solution, it will probably become more feasible in the future. It is the best way to get rid of it.
