Chernobyl could never have happened without the Soviet Union being colossal fuckups. Modern reactors are 1000 times safer than Chernobyl and even that reactor could not have blown like it did without stunning levels of incompetence. Fukushima was a 1 in a million combination of earthquake and flood that they didn't plan for, and as of now it has a death toll of zero? Compare this with the amount of deaths involved with fossil fuel extraction and power generation and it's not even close. Spent fuel is not dangerous unless you are sleeping within a few feet of it and
we did come up with an extremely safe plan for disposal of itif not for the NIMBYs in Nevada.
Yeah, but that's the problem with nuclear power plants or any other complicated system: humans. Given enough time and opportunity, shit will eventually go sideways. Yes, Chernobyl was a chain of events of staggering incompetence, but the fact is that it happened, and to this day there is an exclusion zone of 1,000 square miles around it. Fukushima was NOT a "1 in a million combination of earthquake and flood". Japan is an extremely tectonically active country, and they all knew that. They knew there were massive risks with any coastal power plant in that country. And despite that, TEPCO and the nuclear regulatory agency completely failed to address the risks properly. A nuclear power station being flooded and losing grid power was a virtual certainty in Japan at some point, and even in one of the best run, most developed countries on the planet their regulatory system abjectly failed to ensure that the risks were properly addressed and bam, there's now 4,500 square miles of Japan where radioactivity levels exceed the government's allowable exposure rate. When it's all said and done, the economic consequences and the total cost to clean that shit up is probably going to be a couple hundred billion dollars.
So what happens when developing, middle income countries with far worse regulatory structures like China, or various Eastern European countries, or god forbid African ones start cranking out more reactors? People will find a new way to fuck up, of that you can be guaranteed. And when the number of reactors is double or triple or quadruple, that just means there's that much more opportunity for shit to go sideways.
Don't get me wrong, I'm not saying that nuclear power is inherently unsafe. I'm saying that getting the right mix of regulatory and cultural factors in place to ensure their safe operation is very, very difficult. And when the consequences are as dire as they are with nuclear reactors, it really can be a scary proposition to consider that China is building dozens of them, and other countries like Vietnam, Iran, the UAE, Jordan, Kazakhstan, Pakistan, and others also have plans to build more. If Japan can fuck it up, any of those countries certainly can.
If Canada, the US, UK, France, or Germany were to announce "hay guys, we're building a dozen reactors to completely eliminate fossil fuel fired power generation" I'd applaud them, so long as the costs made sense and there wasn't any sort of relaxation of regulatory requirements. It's the countries
actually building themthat worry me.
