From the article:

Iran has one industrial-scale uranium enrichment plant near Natanz, in central Iran. The IAEA said earlier this month that about 8,600 centrifuges had been set up in Natanz, but only about 4,000 were enriching uranium. The facility will eventually house 54,000 centrifuges.

The newly revealed enrichment site, known as Fordo, is a small scale site that will house nearly 3,000 centrifuges.

IRNA said the Cabinet ordered that the 10 new sites have a scale equal to Natanz's.
