I am not anti-nuclear. All energy used by life on earth comes from nuclear energy. (The sun is fusion, geothermal energy is fission. We are not near enough to a large gravitational mass to have that as an energy source.)
What I am, is a staunch adherent to the absolute, and non-negotiable need for REAL regulatory oversight of manmade nuclear energy. It's the strongest source of energy we know, and it needs the proper diligence.
Fukushima Diaichi? Everything about that can be attributed to lax regulation and oversight. I am not against nuclear plants; I am against poorly run nuclear plants, and "profits over all!!" mentalities. Many people are the same way, but have gotten so soured by the flagrant degree of regulatory capture that happens in "big expense ticket" operations like nuclear, that they feel proper oversight is not "realistically possible", and so they come out against nuclear in practice.
It's one of the reasons I am so pro fusion, even though we are still many years away from working scale reactors. The risks involved are much lower, and with the inevitability of lax oversight happening eventually, at least the damage done by a "disaster" would be minimal compared to fission.
In the mean time, we can limp along getting second hand nuclear energy from wind and solar, and try to wrestle the corpses of the petrochem magnates off our futures as best we can.
