VIENNA, Austria (AP) — Raising doubts about its commitment to dispel international distrust, Iran is producing significant quantities of a gas that can be used to make nuclear arms just days before it must stop all work related to uranium enrichment, diplomats said Friday.
Iran recently started producing uranium hexafluoride at its gas-processing facilities in the central city of Isfahan, the diplomats told The Associated Press.
When introduced into centrifuges and spun, the substance can be enriched to varying degrees. Low-grade enriched uranium is used in nuclear power plants. Highly enriched uranium forms the core of nuclear warheads.
While Iran says it is only interested in enrichment to generate power, the United States and its allies accuse Tehran of wanting the technology to make weapons-grade uranium.
