Deputy head of Iran's Atomic Energy Organization Mohammad Saeedi said on Sunday that the International Atomic Energy Agency (IAEA) is now monitoring 5,000 operating centrifuges in Natanz facilities.
Saeedi made the remark on the sidelines of the First International Seminar on 'Nuclear Power Plants, Environment and Sustainable Development' in Tehran on Sunday.
There is no concern over peaceful application of such centrifuges because the IAEA monitors all of them one by one and even pay snap inspection to control their activities.
IAEA in its recent report has confirmed that Iran had increased the umber of operating centrifuges in Natanz from 3,800 to about 5,000, he said.
Since Iran has had very close cooperation with IAEA and it has remained committed to its Modality Plan, Iran's nuclear dossier should return from UNSC to IAEA, he said.
On Bushehr nuclear power plant, Saeedi said most parts of the job has been accomplished and the nuclear power plant will become operational next year.
