Iran has yet to give an explanation over a small quantity of missing uranium metal from a research site, the U.N. nuclear watchdog said in a report that voiced concern over possible military links to Tehran's nuclear program.

Iran will present a new advance in its atomic program Wednesday by loading domestically made nuclear fuel into a research reactor in the capital Tehran, a senior Iranian official told a Russian news agency Tuesday.

Iran is conducting final tests at its first nuclear power plant and it is expected to start generating electricity in the next two months, Iranian media said on Monday.

Russia, which helped build the plant, emphasized that it could not be used for nonpeaceful purposes, though the United States had urged a delay in its opening.

Iranian President Mahmoud Ahmadinejad says the country will enrich its uranium to higher levels, despite pressure to stop.
