Iranian President Mahmoud Ahmadinejad is to unveil several unspecified nuclear "achievements" on Wednesday, his government's website said.

"Several completed nuclear projects will be unveiled tomorrow in the presence of the president," the official website said Tuesday.

"Experts believe these achievements will show the world the extraordinary capability and knowledge of Iranians."

It added the progress will underline Iran 's scientific adherence to "nuclear power for all and nuclear weapons for none," the website said.

The announcement confirmed a vow made by Ahmadinejad Saturday to inaugurate "important nuclear projects" within "days," in a speech marking the anniversary of Iran 's 1979 Islamic revolution.

Iran 's progress in its nuclear program has deeply unsettled the West and Israel , which see it masking a drive for atomic weapons. A report by the UN nuclear watchdog in November also expressed strong suspicions in that sense.

Tehran , though, has repeatedly said its nuclear activities are exclusively peaceful in nature.

It has also claimed to be ready to resume stalled talks with world powers over its nuclear program but has yet to formally reply to a letter sent by EU foreign policy chief Catherine Ashton nearly four months ago offering negotiations.
