Iran's senior national security official here Tuesday said Tehran is not insisting on producing all its required nuclear fuel by itself.
Ali Larijani, secretary of the Supreme National Security Council (SNSC), however, added the country never allows its production independence to be endangered.
Iran's chief nuclear negotiator, who addressed an international conference dubbed "Iran's Nuclear Energy Program: Policies and Prospects", noted there is no international rule on supply of fuel required by nuclear power plants.
US President George Bush has vowed to establish a "fuel bank", recalled the official, adding the proposal lacks international support and that Iran will have no alternative but to demand for fuel if it accepts such a proposal.
Wondering about recent remarks of US and European officials that Iran enjoys rich oil and gas reserves and does not require nuclear energy, Larijani pointed to two documents signed in the pre-Revolution era that contradict the West's claim.
Tehran and Washington inked a document during the Shah's rule on establishment of power plants for generation of 20,000 megawatts of electricity in Iran, the ranking official said.
Larijani also referred to a 1974 Iran-France agreement on construction of power plants and generation of 6,000 megawatts of electricity in Iran.
Article 4 of the Tehran-Paris pact says the (uranium) enrichment work, a part of nuclear fuel production process, is done on Iranian soil, he added.
Iran's oil and gas reserves at the time the contracts were signed -- more than 30 years ago -- exceeded today's reserves, noted Larijani, raising the question "Why do Americans and Europeans now claim that Iran requires no nuclear energy?"
"Before the victory of the (Islamic) Revolution, Europe stored 1,600 tons of yellow cake and 60 tons of UF6 that belonged to Iran," said the SNSC secretary, adding, "Europeans refused to deliver the mentioned yellow cake and UF6 after the Revolution.
"So the Westerners' disloyalty forced Iran to think of fuel production. Now they may give guarantees that Iran's fuel need will be met, but we cannot trust them because their behavior changed in the post-Revolution era."
