I'm not a big fan of fission reactors. Under normal circumstances, they're very safe, true enough. But there are two weaknesses: human mismanagement and malfeasance (Chernobyl), and black-swan natural disasters (Fukushima). All well and good to say you're building a reactor somewhere "safe," but the very nature of black-swan events is that they are not foreseen or foreseeable, and sometimes do hit "safe" areas. And when they do, the resulting radiation release can be highly damaging, with effects that last decades, even centuries and beyond.
Having said that, I do believe we're going to have to build more fission reactors, as the Oil Age is coming to an end sooner than most people realize. But what is really needed is a new Manhattan Project into thermonuclear fusion for electric power. The reason why fusion power is "always 50 years away" is because we have that mentality. Gather the 20 best minds on the planet, put them into a room, give them a budget of $500 billion and offer them each a $20 million bounty for successful completion of the first commercially viable thermonuclear reactor, and we could probably have it up within a decade. That's pretty much how we got the atomic bomb sooner rather than later...Roosevelt got the brains together and refused to take "no" or "maybe someday" for an answer.
