Europe has about 60,000 tons of nuclear waste storage[1], so lets say the global nuclear waste quantity is 2-3x or 120,000 to 180,000 tons. That sounds like a lot, however it's less than 2 weeks of coal deliveries to a coal plant (at 1 train of 115 cars each with 116 tons of coal = 13,340 tons delivered per day[2]). To take another approach, the average landfill size is 600 acres[3].
The "eh, just bury it" approach is really not a bad one. Its not even that much stuff to bury
I thought something like 30 tons per Gwatt capacity per year was the ballpark for high level waste without reprocessing? How are you arriving at a 120,000 ton estimate?
Sure there isn't a prohibitive quantity either way but regardless I think the 120k number might be off by one or two orders of magnitude even before reprocessing reduces the amount by ~95%.
