Fukushima was hardly an accident, it was a tsunami that killed a thousand times more people than the ensuing nuclear power plant leak ever did
Not very deadly, luckily yes. But cleaning up the accident has been expensive.
It IS expensive. And will take another 30 years to complete.
Apparently every accident that has happened will never happen again and is a once off. So they don’t count.
It's not that they don't count. They count just as much as air pollution, heat stroke or hypothermia, from fossil fuels and expensive or unreliable energy.
Nuclear has costs, yes. Weigh them up against the costs of every other alternative, rather than singling them out.
The tsunami alone killed 10000 people, displaced many more. The nuclear accident that followed killed 1 (one). So nuclear made the disaster 0.01% worse.
But nuclear is also the reason why it's still an ongoing expensive issue 10 years later.
