Fissionable

摘要

Is Iran secretly building a bomb? And if so, is there much anyone can do about it? Suspicions that it was up to no nuclear goodintensified earlier this year when officials from the International Atomic Energy Agency (IAEA) reported that Iran was building a surprisingly sophisticated uranium-enrichment plant at Natanz. First reports of this plant, and another for making heavy water at Arak, had come last year, not from the Iranian government but from an exiled opposition group. Both enriched uranium and plutonium have legitimate civilian uses, but they are also essential as the fissile cores for bombs.
