TEHRAN, Dec. 6 (Xinhua) -- A senior Iranian nuclear official dismissed on Saturday the recent reports that Iran has agreed to allow snap inspection of the country's nuclear facilities, Press TV reported.

"The IAEA's inspections of Iran's peaceful nuclear program will be carried out on a monthly basis, just like before," Behrouz Kamalvandi, spokesman of the Atomic Energy Organization of Iran, was quoted as saying.

"The extent and type of inspections of Iran's nuclear activities, during the seven-month period of nuclear talks extension, will continue on its regular basis," Kamalvandi said.

Recent western media reports that Iran has made "significant concessions" in recent nuclear talks "including promises by the Islamic republic to allow snap inspections of its facilities and to neutralize much of its remaining uranium stockpile."

In the meantime, a source close to Iran's team of nuclear negotiators denied on Saturday some reports saying that the country might refrain from testing new models of centrifuge machines used to enrich uranium, stressing that research and development activities in the enrichment field are firmly in place in Iran, according to Tasnim news agency.

"The process of research and development in (uranium) enrichment is underway routinely and normally in the Atomic Energy Organization (of Iran)," the source was quoted as saying.

On Thursday, western media also reported that Iran would refrain from testing new centrifuges under an extended nuclear deadline agreement with the P5+1 group (China, the United States, France, Britain, Russia plus Germany) reached in November.

Iran's top nuclear negotiator, Abbas Araqchi, said on Thursday that the ground was prepared for a final deal with world powers over Tehran's nuclear issue.

Earlier on Nov. 24, foreign ministers from the Islamic republic and the P5+1 group agreed to extend the deadline for another seven months, after they failed to meet the initial Nov. 24 deadline for a comprehensive deal over Iran's nuclear program.

Under the agreement, an interim deal reached on Nov. 24, 2013 will also be extended to June 30, 2015, with a fresh round of talks resuming in December.
