The Coming Uranium Crisis

tcd004 writes "MIT reports that the world is running out of fuel for our nuclear reactors due to production limitations and an aging infrastructure. Nuclear power has gained popularity as a carbon-free energy source in recent years, but Dr. Thomas Neff, a research affiliate at MIT's Center for International Studies, warned that fuel scarcity could drive up prices and kill the industry before it gets back on its feet. Passport has pulled together some interesting numbers: there are 440 reactors currently in operation and 82 new plants under construction. The demand for fuel has driven the price of uranium up more than 40% in the last few months — 900% over the last decade. You can follow the spot price for a pound of uranium. "

Which is why India's looking at thorium...

[meringuoid]

... Uranium's not all that abundant, we've known that for years. But the breeder reactors they're building in India can convert thorium to fissile material as a byproduct of their operation. There's enough potential energy in the available thorium supply to run the planet for an awfully long time. Whether it's economical to do so at present is another matter, but for long-term security there's no better consumable.

This article is just another resource scare article. Uranium is not like oil in that it only forms in the upper levels of the crust on the Earth. You can find Uranium anywhere in the solar system. When they say that uranium is becoming scarce they mean that it is becoming scare in the east to reach places of the top 0.5 km of the 6371 km radius Earth.

In an age where people understand such development principles like Moore's Law, you would think that people would have a little more imagination when it comes to the future of resource exploration in the next century or so.

Breeder reactors can also convert U238 to fissile plutonium, which is if anything more useful, since we already have reactors designed for Pu239 and I don't believe any reactors have yet been designed for Th233.

The problem is that people paranoid about nuclear proliferation have successfully made it very politically difficult (it's not technically completely straightforward, you're running rather fiddly chemistry by remote-control in a very high radiation environment) to reprocess spent fuel to get the plutonium out for reuse.

So the current nuclear fuel cycle is the equivalent of running a basic oil refinery, taking out the small jet-fuel fraction from crude oil, and then pumping the remainder back into the ground in places deliberately chosen to make it hard to take it out again. Breeder reactors are the equivalent of those catalytic-cracking columns in refineries which can make something useful out of the heavier crude-oil fractions.

99.5% - Integral Fast Reactor (IFR)

[bill_mcgonigle]

Breeder reactors reuse spent nuclear fuel. They only need small amounts of fuel to keep the reaction going. However, what about the waste? Compared to a conventional reactor, how much radioactive waste do they produce?

The Integral Fast Reactor (IFR) would have used 99.5% of the fuel. The remaining 0.5% of the waste would have had the characteristic of decaying to ore-levels of radiation within 300 years. That's nearly a 100-fold decrease in the amount of nuclear waste we'd have to deal with, and orders of magnitude shorter time for protecting the waste. The waste is also attractive from a non-proliferation standpoint

Unfortunately, the Clinton Administration defunded the IFR project almost immediately after taking office and killed it properly two years into the first term. After all, how can you count on donations from the NONUKES lobby if safe, responsible fission power is available?

Bush hasn't restarted the project either, so there's plenty of blame to go around in Republicrat circles.

We should finish the research and build at least one of these reactors at the Yucca Mountain site. There we can burn all of the incoming waste fuel, and light up Las Vegas or something with the energy. If it were only for waste disposal it would be a good idea, but once the research is done we also have a system for solving Global Warming. China is even interested but they're going with Pebble Bed Reactors since the IFR work wasn't finished. I'd be happy for them to finish the work, but perhaps they don't have the qualified staff. I abhor those who think Global Warming is man-made and dangerous and refuse to embrace technology like IFR. Even the founder of Greenpeace is a 'shill' for the nuclear industry - he recognizes you have to make choices, and none of them are perfect, but such is life. The choice matrix is simple if we want to get this solved this century: man-made global warming, nuclear, or agrarian society. Pick one.

I understand Bill Richardson groks these issues. I wish he'd come out in full support of solving our energy problems instead of beating around the bush on it. I'd definitely vote for him if he did, and I'm not in the habit of voting Democrat. Oh, and it also solves our little geopolitical security problem, depowers the middle east despots, and bolsters our economy.
