It has nothing to do with technical issues, safety issues, reliability or cost.
It has mainly to do with public stupidity, fear and ignorance.
From a technical standpoint it is the only thing that will work. Unfortunately, fossil fuel marketing, of which the solar/wind/hydrogen/battery scams are members of a very successful subset has succeeded in demonizing it, as it is the only technology that can eliminate fossil fuels.
Today, around 19,000 people will die from air pollution, as they have every day this year, every day last year, and every day of the last several decades. Obviously climate change is making everything worse, far worse.
Still we have people carrying on about the Sendai Earthquake which besides destroying a city with seawater, and killing around 20,000 people with collapsing buildings and drowning, also destroyed three nuclear reactors at Fukushima.
While the planet burns, people care only about the reactors, although the number of deaths associated with radiation is, if not zero, vanishingly small.
Around 80 million people died from air pollution since Fukushima, and no one gives a rat's ass.
The problem with nuclear energy is not, again, technical. It is essentially infinitely expandable. The problem is one that appears in many other places beyond energy and the environment, but which dominates energy and the environment, the embrace of the marketing of ignorance.
Am I clear?
