Joint projects with Russian nuclear scientists began to ebb soon after President Vladimir Putin came to power in 2000, and reached a nadir last October when Russia suspended an agreement with the United States on nuclear R&D cooperation and terminated another on retooling Russian research reactors to no longer run on weapons - grade uranium fuel.

In the wake of the Cold War, the Unites States and Russia had excess weapons - grade uranium and plutonium.

Olli Heinonen of Harvard University calculates that it would take Iran six months to make enough weapons - grade, 90 per cent uranium - 235 for a bomb from the 3.5 - per - cent fuel - grade uranium it makes at Natanz under UN surveillance, but only a month starting from 20 - per - cent.

Add to this the fact that an increase in nuclear reactors will lead to a depletion of uranium stocks within a century - unless you factor in «breeder reactors» that have so far been shunned as they can produce weapons - grade nuclear materials - and nuclear ambitions start to look decidedly shaky.

The higher uranium price reflects the need to move to ever deeper mines, which increases the energy needed to extract the ore, and the shift to lower - grade ore.
