Fukushima nuclear disaster in 2011 was among the worst nuclear disasters in history; not only because its human toll was so high, but also because it was the "final straw" -- so to say -- in public opinion in Western countries that made people scared of nuclear energy. Nuclear energy remains the safest, cleanest way to produce energy but Chernobyl and Fukushima significantly reduced the funding going into this kind of research, because public opinion was very much against nuclear power. It is getting better recently, but if history shows anything in the next 20 to 30 years we will have another disaster that will change public opinion again.
I see. Thanks for the explanation. I had been thinking in terms of the technology rather than in its public perception (although sure… that perception influences funding for the technology).
Now I see that I would have been well served by looking up 'nuclear 2011' and 'nuclear 1986' since those disasters are very famous.
