CERN Physicist Warns About Uranium Shortage
eldavojohn writes "Uranium mines provide us with 40,000 tons of uranium each year. Sounds like that ought to be enough for anyone, but it comes up about 25,000 tons short of what we consume yearly in our nuclear power plants. The difference is made up by stockpiles, reprocessed fuel and re-enriched uranium — which should be completely used up by 2013. And the problem with just opening more uranium mines is that nobody really knows where to go for the next big uranium lode. Dr. Michael Dittmar has been warning us for some time about the coming shortage (PDF) and has recently uploaded a four-part comprehensive report on the future of nuclear energy and how socioeconomic change is exacerbating the effect this coming shortage will have on our power consumption. Although not quite on par with zombie apocalypse, Dr. Dittmar's final conclusions paint a dire picture, stating that options like large-scale commercial fission breeder reactors are not an option by 2013 and 'no matter how far into the future we may look, nuclear fusion as an energy source is even less probable than large-scale breeder reactors, for the accumulated knowledge on this subject is already sufficient to say that commercial fusion power will never become a reality.'"
What about plutonium and other radioactive materials? (first post? hehehe)
Religion: The greatest weapon of mass destruction of all time
Why not build Thorium-based reactors instead? The material is 100x more abundant. The USA has an ample natural supply. You get 10 times the energy because you don't have the 238 problem. There is almost no waste and the byproducts decay within a human lifetime. And you can't use them to make nuclear weapons.
I first read through this article when it was first posted on the oil drum weeks ago, and at the time it just seemed ... wrong, somehow. I've since spent a lot of time doing my own research and reading on the topics, and I feel Dr. Dittmar has been intellectually dishonest in at least a few areas. Further, the organization of the article is terrible, mixing sections and topics in a confusing fashion. I suspect this is intentional.
Prime examples of issues in the article:
- He uses nonstandard terminology with respect to breeding gain, and in several places uses phrases such as 'has only a maximum theoretical breeding gain of 0.7' in a context that implies that anything below 1.0 is not self-sustaining. Once armed with a better understanding of the terminology I was able to put his comments into proper context, but this just made the negative spin obvious instead of allowing it to slip under the radar.
- He makes the claim that no thorium breeder has ever reached breakeven, when in fact the very first one assembled had a net gain after operation.
- He makes the claim that no currently online breeder reactors are at breakeven, combined with claims that breeder reactors are a huge proliferation concern, neglecting the fact that most currently operational breeders were designed explicitly to have slightly less than breakeven gain precisely to address proliferation concerns.
In short, while he may be competent and he may be very experienced, there is a clear agenda behind this. The paper contains a substantial amount of spin and FUD, and further is organized in such a fashion as to make it difficult to analyze. I would firmly lump it into the 'armchair FUD' category instead of 'unbiased scientific position paper'. YMMV.
