Iran starts enriching uranium to 60%


Iran began enriching uranium to 60%, its highest level ever, edging closer to weapons-grade levels to pressure talks in Vienna aimed at restoring its nuclear deal with world powers after an attack on its main atomic site.

About the current increase in enrichment by Iran

  • A top official said only a few grams an hour of uranium gas would be enriched up to 60 % purity — triple the level it once did but at a rate far slower than what Tehran could produce.
  • International inspectors already said Iran planned to do so above-ground at its Natanz nuclear site, not deep within its underground halls hardened to withstand airstrikes.
  • The move is likely to raise tensions even as Iran negotiates in Vienna over a way to allow the U.S. back into the agreement and lift the crushing economic sanctions it faces. However, its scope also provides Iran with a way to quickly de-escalate if it chose.
  • While 60 % is higher than any level Iran previously enriched uranium, it is still lower than weapons-grade levels of 90 %.
  • Iran had been enriching up to 20 % — even that was a short technical step to weapons grade. The deal limited Iran’s enrichment to 3.67 %.
  • Iran insists its nuclear program is peaceful, though the West and the IAEA say Tehran had an organized military nuclear program up until the end of 2003.
  • Iran previously had said it could use uranium enriched up to 60 % for nuclear-powered ships. However, the Islamic Republic currently has no such ships in its navy.

About Uranium Enrichment

  • Natural uranium consists of two different isotopes – nearly 99% U-238 and only around 0.7% of U-235.
  • U-235 is a fissile material that can sustain a chain reaction in a nuclear reactor.
  • Enrichment process increases the proportion of U-235 through the process of isotope separation (U-238 is separated from U-235).
  • For nuclear weapons, enrichment is required upto 90% or more which is known as Highly Enriched Uranium/weapons-grade uranium.
  • For nuclear reactors, enrichment is required upto 3-4% which is known as Low Enriched Uranium/reactor-grade uranium.
  • Highly enriched uranium has a concentration of 20% or more and is used in research reactors.

About the 2015 Nuclear Deal

  • In 2015, Iran with the P5+1 group of world powers – the USA, UK, France, China, Russia, and Germany agreed on a long-term deal on its nuclear programme.
  • The deal was named as Joint Comprehensive Plan of Action (JCPOA) and in common parlance as Iran Nuclear Deal.
  • Under the deal, Iran agreed to curb its nuclear activity in return for the lifting of sanctions and access to global trade.
  • The agreement allowed Iran to accumulate small amounts of uranium for research but it banned the enrichment of uranium, which is used to make reactor fuel and nuclear weapons.
  • Iran was also required to redesign a heavy-water reactor being built, whose spent fuel would contain plutonium suitable for a bomb and to allow international inspections.
  • In May 2018, the USA abandoned the deal criticising it as flawed and reinstated and tightened its sanctions.
  • Since sanctions were tightened, Iran has been steadily breaking some of its commitments to pressure the remaining signatories to find a way to provide sanctions relief.


  • Enrichment could shorten Iran’s time it would take to develop a nuclear bomb.
  • Previously the International Atomic Energy Agency (IAEA) expressed serious concerns over Iran’s blocking of inspections of two suspect locations of Uranium enrichment for more than four months.
