Since you're probably not a regular reader of the trade publication Nucleonics Week, let me summarize an article that appeared in its Oct. 8 issue. It reported that Iran's supply of low-enriched uranium -- the potential feedstock for nuclear bombs -- appears to have certain "impurities" that "could cause centrifuges to fail" if the Iranians try to boost it to weapons grade.
You've got to hand it to the Iranians, though, for making the best of what might be a bad situation: In the proposal embraced in Geneva, they have gotten the West to agree to decontaminate fuel that would otherwise be useful only for the low-enriched civilian nuclear power they have always claimed is their only goal.
"It's especially cheeky for Iran to try to leverage as a concession their willingness to receive international cooperation in supplying nuclear fuel," noted George Perkovich, the director of the nonproliferation program at the Carnegie Endowment for International Peace.
