Solar now being the cheapest energy source made its rounds on Lemmy some weeks ago, if I remember correctly. I just found this graphic and felt it was worth sharing independently.

"Today there are about 440 nuclear power reactors operating in 32 countries plus Taiwan, with a combined capacity of about 390 GWe. In 2022 these provided 2545 TWh, about 10% of the world's electricity."

There have been two major reactor accidents in the history of civil nuclear power – Chernobyl and Fukushima Daiichi. Chernobyl involved an intense fire without provision for containment, and Fukushima Daiichi severely tested the containment, allowing some release of radioactivity.

Yes- a track record of one plant failing due to Soviet incompetence and political blunders; and the second failing due to checks notes a 9.0 magnitude almost direct earthquake and ensuing 133 ft tsunami.

Worth noting that the Fukushima disaster would have been prevented if they heeded warnings in a 2008 report that said their sea walls were too short, so again incompetence.

the earthquake didn't even damage the plant, they thought of that. the tsunami knocked out the power lines and bad generator placement led to loss of power for cooling. build reactors to passively cool themselves (which should just be a mandatory safety feature on new reactors tbh, it's not a big ask and improves safety a lot) and fukushima type accidents become impossible. that plant was so old that the original operating license was going to expire a week after the quake and the only guy who died had a heart attack. fukushima-sized death tolls happen in the rooftop solar installation industry every year, totally unreported.
