In a move possibly meant to deflect attention from his domestic political woes, Iranian President Mahmoud Ahmadinejad on Sunday ordered the nation's atomic energy agency to begin enriching uranium to a higher level of purity to serve as fuel for a Tehran medical reactor. The command to enrich uranium from 3.5% to 20% purity comes amid Iran's diplomatic impasse with the United States and its allies over a proposal to exchange nuclear fuel that the international community hopes would slow the development of Tehran's nuclear capabilities.

The international community waited anxiously today for Iran's response to a proposal to transfer the bulk of its nuclear material abroad to be turned into fuel for a peaceful medical research and treatment reactor. Earlier in the day, the United States, Russia and France formally signed off on the plan, which would retrofit the bulk of Iran's nuclear fuel stockpile into rods for a Tehran reactor used to diagnose and treat cancer. The U.S. delivered its positive response to the proposal to Mohamed ElBaradei, chief of the International Atomic Energy Agency, or IAEA, a spokesman for the National Security Council confirmed this morning.

Workers struggling to contain radioactive releases from the Fukushima power plant face two critical tasks to avoid turning a nuclear disaster into a catastrophe: preventing a runaway chain reaction into the nuclear fuel and maintaining a massive flow of seawater through the damaged pools and reactor vessels. There are few options, none of them good. "The most imaginative engineers in the world couldn't have dreamed up a situation like this," said Najmedin Meshkati, a USC professor and nuclear power expert.

Iran has proposed setting up a nuclear fuel production facility within its borders with international help, the Iranian Embassy said Tuesday. The proposal is an alternative to Russia's offer to play host to Iran's nuclear fuel production to ease concern that Tehran could develop weapons. Iran says its nuclear program is for generating electricity.

A device that was lowering a nuclear fuel bundle into a pool of water at the Pilgrim plant accidentally dropped its load Wednesday, but no damage was detected, plant officials said. A refueling process that was about two-thirds complete was halted.

Iran has launched a second batch of centrifuges at its pilot nuclear fuel plant despite possible U.N. Security Council sanctions, diplomats said. Tehran this month fired up the new cascade of 164 interconnected centrifuges, which can enrich uranium for power-plant or nuclear-bomb fuel, to go with an initial batch of 164 centrifuges, the diplomats said.

Scientists have been trying to harness the secrets of star power since the days of the Cold War. Now, using a 2-millimeter capsule housed in a cavernous building roughly the length of three football fields, researchers have conducted a landmark experiment, using lasers to create the merest hint of controlled nuclear fusion that produced more energy than was put into the fuel alone. “This is really an important milestone,” said UCLA plasma physicist Warren Mori, who was not involved in the work.
