From a U.C. Berkeley PR interview with Steven Chu, Sept. 30, 2005:
Should fission-based nuclear power plants be made a bigger part of the energy-producing portfolio?
Absolutely. Right now about 20 percent of our power comes from nuclear; there have been no new nuclear plants built since the early ’70s. The real rational fears against nuclear power are about the long-term waste problem and [nuclear] proliferation. The technology of separating [used fuel from still-viable fuel] and putting the good stuff back in to the reactor can also be used to make bomb material.
And then there’s the waste problem: with future nuclear power plants, we’ve got to recycle the waste. Why? Because if you take all the waste we have now from our civilian and military nuclear operations, we’d fill up Yucca Mountain. [Yucca Mountain, which sits on federal land in Nevada , is under consideration as a long-term storage facility for spent nuclear fuel.] So we need three or four Yucca Mountains. Well, we don’t have three or four Yucca Mountains. The other thing is that storing the fuel at Yucca Mountain is supposed to be safe for 10,000 years. But the current best estimates – and these are really estimates, the Lab’s in fact – is that the metal casings [containing the waste] will probably fail on a scale of 5,000 years, plus or minus 2. That’s still a long time, and then after that the idea was that the very dense rock, very far away from the water table will contain it, so that by the time it finally leaks down to the water table and gets out the radioactivity will have mostly decayed.
Suppose instead that we can reduce the lifetime of the radioactive waste by a factor of 1,000. So it goes from a couple-hundred-thousand-year problem to a thousand-year problem. At a thousand years, even though that’s still a long time, it’s in the realm that we can monitor – we don’t need Yucca Mountain.
Interesting to note up top, though, is that Steven Chu is a signatory on the DOE Labs’ report “A Sustainable Energy Future: The Essential Role of Nuclear Energy,” released this past August. You can read that here (as a pdf).
