Iran is to formally inaugurate its new nuclear power plant today. The opening ceremony of the Bushehr plant would be attended by Russian Energy Minister Sergei Shmatko and head of Russian state atomic agency Rosatom Sergei Kiriyenko. The Iranian side will be represented by its energy minister and head of the Atomic Energy Organization. Construction of the Bushehr plant was started in 1975 by several German companies. However, work was halted when the United States imposed an embargo on hi-tech supplies to Iran after the 1979 revolution. Russia signed a contract with Iran in 1998 to complete the construction.
