The Islamic Republic has been under international pressure since it resumed uranium enrichment in January 2006, which some Western countries suspect is part of a covert nuclear weapons program.
Although Tehran has repeatedly claimed its program is peaceful, the UN Security Council adopted a resolution in December imposing sanctions on the country.
Mikhail Margelov, head of the Federation Council's International Affairs Committee, said: "A committee delegation will visit Iran February 18 through 21, and obviously, the controversy over the country's nuclear program will also be on the agenda."
The sanctions approved in response to Iran's nuclear ambitions banned activities involving uranium enrichment, chemical reprocessing, heavy water-based projects, and the production of nuclear weapons delivery systems.
On February 23, the International Atomic Energy Agency, the UN nuclear watchdog, is expected to file a report on Iran's nuclear progress.
The senator reiterated Russia's position on Iran's nuclear program. "You cannot find a single responsible political figure in Russia who would wish Iran to possess nuclear weapons," he said.
Russia, a key economic partner of Iran, has consistently supported the country's right to nuclear power under the Nuclear Non-Proliferation Treaty (NPT), and insisted that a previous, harsher draft of the resolution be revised and softened.
