Rebutting Rees in the Ecologist and the Guardian

Eifion Rees wrote an article for the Ecologist and later republished it in the Guardian. The article was called "Don't believe the spin on thorium being a ‘greener’ nuclear option." I wrote a rebuttal to the article here.

Thoughts on Lester Brown's "Plan-B"

Last night I was flying back from speaking at TEDxYYC to Alabama and I had a bit of time on my flight, so I watched a program that I had recorded on PBS a few days earlier. It was called "Plan-B: Mobilizing to Save Civilization" and it focused mostly on the work of Lester Brown of the Worldwatch Institute, as he travelled the world and particularly through Asia discussing how climate change would affect food production, and ultimately, civilization. The program began with what has become fairly standard fare in these types of programs, describing how fossil fuels have ...

What's in Spent Nuclear Fuel? (after 20 yrs)

Lately I've been looking a lot at spent nuclear fuel, particularly what's in it and what's radioactive after a while. I've seen graphs of fission product distributions before, but they're always of fission products by atomic mass, and they're usually showing the distribution right after the fission event. I wanted to know what was in there from an elemental perspective, because if you're going to do chemical processes on the spent nuclear fuel, you'll be removing elements, not isotopes. So how do they all rack-and-stack overall? Well, here's the results for a typical ...

Picture of Neutron Poisons

In nuclear reactor design, we describe the cross-section of different nuclides in a unit called a "barn". It has units of area. So what does that mean? Well, take a look at this picture. This shows five important nuclides plotted against each other, with their size determined by their "barns". You can see that one of them is absolutely HUGE. That is xenon-135, as far as I know, the nuclide with the largest cross-section to absorb thermal neutrons. Next on the list of trouble is samarium-149, which is really big, but not nearly as big as xenon-135. Again, to the ...

Columbus Dispatch Article on Thorium and LFTR

Doug Caruso of the Columbus Dispatch has written a pair of articles that are appearing in today's issue of the paper. In the article he quotes Dr. Al Juhasz and Dr. George Schmidt of NASA GRC, Dr. Dan Ingersoll of ORNL, Dr. Rich Denning of Ohio State, and me. All of these folks have been involved at one time or another in discussions about LFTR, particularly Al and George. The articles, of course, have to be brief and to the point, but I think they're very good. Thanks Doug!Columbus Dispatch: The mighty thorium, the nearly perfect energy source nobody has heard ...

"Enemies" of the Earth and their Anti-Nuke Ads

"Even if nuclear reactors weren't top terrorist targets..."Lie. A nuclear reactor is a terrible target. It's about the hardest target you could even go after, encased in concrete and steel that would crush a plane in seconds."Even if radioactive waste didn't remain deadly for 10,000 years..."What are you talking about? Are you going to eat it or something? Do you think something magic happens in the 10,001st year? Do you think eating the toxic heavy metals that make up a solar panel is less deadly? Do you think that the impact of a thrown blade from a windmill is ...

Bill Gates Briefly Mentions LFTR–I Think!

Boy, sometimes someone mentions something to a group of people that give a concept a level of credibility no money could buy:13:28 -- "there are some innovations in nuclear...modular, liquid..."23:10 -- "there's a liquid-type reactor, which seems a little hard...but maybe they say that about us."Here's the original link to the TED site.
