I wouldn't. Coal ash takes up an enormous amount of space, and it can blow around too. Nuclear waste takes up a relatively small volume.

- bumby 7y agoInteresting. I think the opposite. Just the fact that we've spent tens of billions on Yucca mountain alone to have it go nowhere makes me think differently. If I was a contractor faced with solving the coal ash problem or the nuclear waste problem, I'd avoid the latter like the plague even if just for the political difficulties, notwithstanding the engineering part of the problem.
- catalogia 7y agoThe only reason trillions of dollars haven't been spent cleaning up the byproducts of burning fossil fuels is because we just dump it into the environment instead. If the fossil fuel industry were held accountable for the waste, it would be much more expensive than the boondoggle that is Yucca mountain. (Particularly if CO2 emissions are properly considered...)
- bumby 7y agoGood point. Any idea on the costs associated with implementing something like carbon capture?
- redwall_hp 7y agoBest so far is 1 gigajoule per ton of CO2: http://news.mit.edu/2019/mit-engineers-develop-new-way-remove-carbon-dioxide-air-1025 http://news.mit.edu/2019/mit-engineers-develop-new-way-remov... Which is pretty much only going to happen if you invest a lot of money into nuclear facilities dedicated to this. 1GJ is about 280 kilowatt-hours.
- ohyes 7y agoYucca mountain is the wrong solution. We can reprocess nuclear fuel waste easily already, reducing this issue by quite a lot. As a policy issue the United States does not, so you end up with much more “spent fuel” than necessary. Radioactive byproducts (steel and such) are a bigger issue, but hopefully you only see a lot of that when you are actively decommissioning a plant.
- bumby 7y agoAs you alluded to, I think it's the policy/political problems that are more difficult to overcome compared to the technical issues. That's the main reason I was assuming it would be easier to solve the coal ash problem
