National Nuclear Energy Day (Persian: ñÃÂò àÃÂàÃÂÃÂçÃÂñàÃÂóêÃÂâÂÂçÃÂ) is observed on 9 April (Farvardin 20th) in Iran. The observation marks the '9 April 2006' when Iran announced it had successfully domesticated the complete cycle of Uranium enrichment despite the sanctions.
In 2003, Iran opposition groups efforts in Western media towards accusing Iran of building a nuclear weapon made Europe and the United States sensitive. These countries tried to halt the Iranian nuclear activities under various pretexts, but on 9 April 2006, Iran was able to complete the full cycle of nuclear fuel production.
In 2010, as part of a ceremony in honor of the holiday, the first sample of the latest Iranian-made nuclear fuel and a model of a third generation centrifuge for enriching uranium were presented.
