Thorium, the Next Nuclear Fuel?
mrshermanoaks writes "When the choices for developing nuclear energy were being made, we went with uranium because it had the byproduct of producing plutonium that could be weaponized. But thorium is safer and easier to work with, and may cause a lot fewer headaches. 'It's abundant — the US has at least 175,000 tons of the stuff — and doesn't require costly processing. It is also extraordinarily efficient as a nuclear fuel. As it decays in a reactor core, its byproducts produce more neutrons per collision than conventional fuel. The more neutrons per collision, the more energy generated, the less total fuel consumed, and the less radioactive nastiness left behind. Even better, Weinberg realized that you could use thorium in an entirely new kind of reactor, one that would have zero risk of meltdown. The design is based on the lab's finding that thorium dissolves in hot liquid fluoride salts. This fission soup is poured into tubes in the core of the reactor, where the nuclear chain reaction — the billiard balls colliding — happens. The system makes the reactor self-regulating: When the soup gets too hot it expands and flows out of the tubes — slowing fission and eliminating the possibility of another Chernobyl. Any actinide can work in this method, but thorium is particularly well suited because it is so efficient at the high temperatures at which fission occurs in the soup.' So why are we not building these reactors?"
- 1/2 the country doesn't believe what scientists tell them: evolution, global warming, birth control/STDs. Why believe them now?
- No new nuclear plants have been built in 30-ish years.
- uranium was thought to be pretty much endless, so why do more research into thorium? (yes, U is getting in short supply now)
- nuclear power still has the stigma of 3 Mile Island and Chernobyl attached to it. It'll be tough to get public opinion on that changed, especially with advances in fuel cell and solar technologies
and worth it even if thorium is slightly inferior as a fuel. In short, it can be a PR win.
Based on the article, I'm not sure that thorium is an inferior fuel. At the very least, it seems more efficient and more abundant, as well as less dangerous than uranium. To me, that's more important than raw power output, especially given that thorium cannot be weaponized.
I prefer small chance of it leaking out (which happened only once) more than the routine of "leaking" it out into biosphere on a daily basis, in the amounts no nuclear power plant will match. As do coal-fired plants.

So still no explanation as to why no common use of Thorium reactors.
Same reason we don't use hemp paper, and why anyone thinking we'll move away from oil based cars before the famine starts is fooling themselves.
The existing corporate status quo makes money doing it this way, and they won't change unless made to (by, say, running out of uranium or oil or what have you).
They have invented a myth that Jews were massacred and place this above God, religions and the prophets. The West has given more significance to the myth of the genocide of the Jews, even more significant than God, religion, and the prophets, (it) deals very severely with those who deny this myth but does not do anything to those who deny God, religion, and the prophet.
Basically, he denies that the holocaust happened. And attacks those who have tolerance of religion or the lack of.
Is it possible for us to witness a world without America and Zionism? You should know that this slogan, this goal, can certainly be achieved.
Basically, not only does he think Israel doesn't have the right to exist, but apparently neither does America.
In Iran we don't have homosexuals like in your country. [...] In Iran we do not have this phenomenon. I don't know who's told you that we have this.
And he not only denies gay rights, but denies that there were even homosexuals in Iran. Even America didn't deny the fact there were black people who were being oppressed. Some might have said that they weren't being oppressed but no one would be as stupid as to say that there is no such thing as black people.
So in light of a politically unstable region, a leader who has made stupid and dangerous comments, how can we say letting them have nuclear power/weapons is a good thing? If Iran wants nuclear power, how about they let the developed nations build and supervise the infrastructure until Iran becomes stable?
Taxation is legalized theft, no more, no less.
What type of nuclear reactor to use it completely unrelated to what fuel to use to power cars.
You aren't going to stick a nuclear reactor in the trunk, and how the grid gets its electricity has no impact on electric cars either.
My point is there is an existing system that involves large amounts of profit in doing it the old way, and the people making said profit have no reason to foster change just because science said so. In fact, given the dismal state of the US education and patent systems, companies often can actively push back by simply hiring, destroying, or buying out people with new ideas.
Look at digital music, for example -- we had to drag the music industry kicking and screaming into the 21st century, and they only came along after they had time to get their lawyers and executives to put down their clay tablets and abacuses long enough to think up some admittedly pretty innovative ways of screwing the rest of us over.
I guess a more succinct way to put it is that corporations have used profit to make science and progress their bitch this past century, and I see no reason why this won't continue going forward.
