Frequently people worrying about environmental impact aren't as concerned about financial impact. I don't care if it cost eleventy-gazillion-bitcoins to decommission a nuclear plant if the alternative is continued global warming and an inhospitable planet when the bill comes due.

>>The truth is that accidents like this can never be cleaned up or salvaged.

I mean that depends on how pedantic you want to get with a "never" and whether you think "sequestered" is good enough or only "salvaged" is acceptable.

Current nuclear isn't great and is incapable of solving climate issues by itself. It still seems like a more viable option than continued reliance on fossil fuels.
