Iran’s chief nuclear envoy Ali Larijani said on Friday that Iran is committed to the peaceful use of nuclear technology but warned the situation could change if his country is threatened.” We oppose obtaining nuclear weapons and we will peacefully use nuclear technology under the framework of the Nonproliferation Treaty, but if we are threatened, the situation may change,” He told a news conference after two days of talks in Beijing. Iran’s nuclear chief said his country has produced and stored 250 tons of the gas used as the feedstock for uranium enrichment, state-run television reported Friday.Vice President Gholamreza Aghazadeh, who is also the head of the Atomic Energy Organization of Iran, said Iran has kept the uranium hexaflouride gas, or UF-6, in underground tunnels at a nuclear facility in Isfahan to protect it from any possible attack.“Today, we have produced more than 250 tons of UF-6. Should you visit Isfahan, you will see we have constructed tunnels that are almost unique in the world,” State-run television quoted Aghazadeh as saying.
