‘Not a very large volume': Expert says Iranian nuclear program has 400kg of enriched uranium
Associate Professor of Nuclear Engineering Patrick Burr says the Iranian nuclear program only has 400 kilograms of enriched uranium, based on International Atomic Energy Agency estimates.
'In the last estimates that we have from the International Atomic Energy Agency, we're looking at about 400 kilograms, possibly a bit more of enriched uranium,' Mr Burr told Sky News Australia.
'That sounds like a large number, but it's not a large volume.
'400 kilograms of uranium … is not a very large volume.
"To give a sense of scale, a football, if it was made of uranium, would weigh something like 35 kilograms, so you'd need 15 maybe, of those footballs, to have the full volume of enriched uranium Iran has.'

US strikes likely have made Iran incapable of making nuclear weapons in a ‘dash effort'
FDD's Nonproliferation and Biodefense Program Deputy Director Andrea Stricker discusses how far the US strikes on Iranian nuclear facilities have set the country's atomic weapons program back. 'The nuclear program has likely been set back many months if not years, we have seen damage to the uranium conversion step, the enrichment and the processing of turning into atomic weapons metal,' Ms Stricker told Sky News Australia. 'Even if Iran wanted to make a nuclear weapon in a dash effort, it likely doesn't have the people or capability to do so.'
