By turning it off and turning it on again

The explosion and blackout at the Natanz nuclear facility in Iran over the weekend might not have been as technologically sophisticated as the Stuxnet cyberattack.

Government officials and news reports gave conflicting accounts of what caused the latest blasts, the extent of damage, and Iran's capacity to recover quickly. Initial reports said there was no harm to the Natanz facility, but Iranian officials later acknowledged damage to its centrifuges.

And while media accounts have suggested saboteurs focused on taking out the facility's electric supply, David Albright, founder and president of the Institute for Science and International Security in Washington DC, believes the aim was to destroy centrifuges.

Power is easy to restore even when electrical equipment is damaged, allowing enrichment work to resume quickly.

But an abrupt blackout that also takes out backup power would have destroyed some centrifuges, Albright says, since they need to be powered down slowly.

Failure to do so leads to vibrations that can cause centrifuge rotors and bellows to become damaged and in some cases, disintegrate, which is what Albright suspects occurred.
