An Iranian news agency says that the country has started using new advanced centrifuges at its main uranium enrichment site.
The semiofficial Fars agency reported Wednesday that a "new generation of Iranian centrifuges" had been installed and operated at the Natanz site in the center of the country.
Earlier in the day Iran said it began loading domestically made nuclear fuel rods into its Tehran research reactor on Wednesday, a defiant move in response to toughening Western sanctions over its controversial nuclear program.
The official IRNA news agency said President Mahmoud Ahmadinejad inserted the first Iranian-made rod into the reactor in northern Tehran, and state TV broadcast live images from the ceremony with Iranian nuclear experts briefing Ahmadinejad on the process.

Iran touted the development as an incremental step in the country's efforts to master the complete nuclear fuel cycle, despite Western penalties and UN sanctions.
The West suspects Iran's nuclear program is aimed at producing atomic weapons, a charge Tehran denies, insisting it's geared for peaceful purposes only, such as energy production. The Tehran reactor, for example, produces nuclear isotopes for treating cancer patients.
The development came as Iran said Wednesday it cut oil exports to six European countries - the Netherlands, Spain, Italy, France, Greece and Portugal - in response to recent new European Union sanctions.
The move comes days after Iran's Oil Minister Rostam Qassemi said Tehran could cut off oil exports to "hostile" European nations as tensions rose over suggestions that military strikes are an increasing possibility if sanctions fail to rein in the Islamic Republic's nuclear ambitions.

Iran argues that the EU oil embargo will not cripple its economy, claiming that the country already has identified new customers to replace the loss in European sales that account for about 18 percent of Iran's exports. Members of Iran's parliament have been discussing a draft bill, although not finalized, which would cut off the flow to the European Union before the latest EU sanctions on Iran go into effect this summer.
Iran has said it is forced to manufacture nuclear fuel rods, which provide fuel for reactors, on its own since international sanctions ban it from buying them on foreign markets. In January, Iran said it had produced its first such fuel rod.
Iran's unchecked pursuit of the nuclear program scuttled negotiations a year ago but Iranian officials last month proposed a return to the talks with the five permanent UN Security Council members plus Germany.
In the past, Iran has angered Western officials by appearing to buy time through opening talks and weighing proposals even while pressing ahead with the nuclear program.
Apart from the EU's recent measures on Iran, which include an oil embargo and a freeze of the country's central bank assets, Washington also recently levied new penalties aimed at limiting Iran's ability to sell oil - which accounts for 80% of its foreign revenue.
Israel is worried Iran could be on the brink of an atomic bomb and many Israeli officials believe sanctions only give Tehran time to move its nuclear program underground, out of reach of Israeli military strikes. The US and its allies argue that Israel should hold off on any military strike on Iranian nuclear facilities to allow more time for sanctions to work.
