I’ll be the one to point out that TMI is exactly what you want to happen in a “nuclear disaster”. Nobody got seriously hurt that we know of, the problem was found and dealt with quickly once identified, and we’ve implemented TONS of extra safeties to make sure that can’t happen again without massive alarms and Serious Lights. Could it have not happened at all? Absolutely. But in a disaster, it’s the perfect “disaster” - nobody died, nobody got seriously injured directly, the plant got screwed up, and $2b to clean up ANY disaster site is honestly pretty damn cheap when we’re talking radioactive heavy metal remediation.
