A quick google search says if we only used nuclear we'd get 40g of waste per person per year assuming western energy consumption standards[1]. Multiply by 8*10^9 people (a little more than the current world population) and you get 320,000 metric tons which is about 3/5th the capacity of the largest oil tankers. Finding a place for that much waste per year is a political problem, not a technical problem. There's plenty of geologically "safe enough to outlast the radioactivity" places we could dig a deep hole (thanks to the fossil fuel industry that is a solved problem) to dump that much waste into.
