Gas centrifuges use centrifugal force to separate the lighter isotopes of uranium-235 from the heavier isotopes of uranium-238. TVEL's report on the tenth generation machine does not specify the ...

TEHRAN, Iran (AP) — Iran announced Sunday that it has begun enriching uranium up to 20% using sophisticated centrifuges at its underground Fordo nuclear plant, state TV reported, an escalation ...

Most of Iran’s centrifuges are in Natanz, the experts said, because a lot of them are required to enrich uranium to 5% — which is the maximum level normally used for nuclear-fueled power stations.

Rather than radiation, experts said the greater risk from any attack on nuclear enrichment sites might be from fluorine gas. Fluorine is mixed with a concentrated form of uranium to create uranium ...

Unenriched uranium typically contains only 0.7% uranium-235. To be used as fuel, it needs to be enriched to between 3.5% and 5%, creating what is known as low-enriched uranium.

Iran’s new workshop at Natanz for making parts for centrifuges, machines that enrich uranium, has been set up underground, U.N. nuclear watchdog chief Rafael Grossi said on Thursday, a move ...

RIYADH, Saudi Arabia–The head of the UN nuclear watchdog said Thursday Iran is operating only several hundred centrifuges at its uranium enrichment plant at Natanz, despite its claims to have ...

North Korea for the first time showed images of the centrifuges that produce fuel for its nuclear bombs on Friday, as leader Kim Jong Un visited a uranium enrichment facility and called for more ...

Iran has hidden sites housing 'hundreds if not thousands' of centrifuges capable of producing weapon-grade uranium, an expert has warned. By Emily Wright, World News Reporter ...

Yang said it’s estimated that North Korea could be operating around 10,000 uranium centrifuges across multiple sites, which account for the core of the country’s nuclear program that likely ...
