No, we’ve known what to do with the waste for decades. Put it in cans, fill the can with cement, coat the can in cement, put the cans in a facility that is protected from geological events like earthquakes, and periodically check the cans/facility. In the US for example, The Yucca Mountain Nuclear Waste Repository was being made before political pressure shut it down.

The waste issue is and always will be one of political pressure and ignorance by the masses, not an actual logistical issue
