TEHRAN (Reuters) - Iran said it will provide the UN nuclear watchdog with the bare minimum of information about its plan to build 10 new uranium enrichment plants, a stance sure to stoke Western suspicions about its atomic agenda. In a defiant response to last weeks International Atomic Energy Agency board of governors vote rebuking Iran for building a second enrichment plant in secret, Tehran said on Sunday it would build 10 more sites like its IAEA-monitored one at Natanz. In 2007, in reprisal for UN sanctions slapped on it, Iran renounced an amended IAEA code of conduct requiring states to notify the agency of nuclear plans as soon as they are drafted, so as to catch any illicit atomic bomb work in the early stages. Iran reverted to an earlier IAEA transparency code mandating only 180 days notice before a nuclear site begins production. A senior Iranian official quoted by official news agency IRNA made clear Iran would apply the minimum transparency rule to its plan for 10 more enrichment plants. A senior Iranian diplomat involved in now stalled nuclear talks with the West said Iran would continue cooperation with the IAEA only according to its 1970s basic safeguards agreement. According to the safeguards, after installation of equipment (centrifuges) and only 180 days ahead of injecting gas into the centrifuges ... we should inform the IAEA, Abolfazl Zohrehvand told IRNA. And we will act within the framework of the safeguard, the former Iranian ambassador to Italy said. Since 2007, Iran officially has stopped implementation of amendments to code 3.1, obliging countries to inform the IAEA when they plan to build a facility, added Zohrehvand. The IAEA has told Iran it was outside the law by failing to declare the second enrichment site taking shape inside a mountain bunker near Qom as soon as plans for it were drawn up. Iran said construction there began in 2007 and the project was hushed up for fear of air strikes by Israel. Iran declared the plant to the IAEA in September after, according to Western powers, learning that their spy services had discovered it. Western diplomats said they had intelligence evidence that the enrichment project was hatched before 2007, and that Iran probably would have used the site to enrich uranium to weapons-grade if it had not been exposed.
