Stuxnet Shoots, It Scores!

Gee, sounds like the pump was continuously running well outside its design parameters while indicating normal operation on its control instrumentation, which is is exactly what Stuxnet was designed to do, run machinery beyond tolerance limits while spoofing the performance display readouts with fake data.

IAEA says Iran’s Bushehr delays were caused by pump

Iran was believed to have told the UN atomic watchdog that a broken pump had made it necessary to remove fuel from its first nuclear power reactor, independent experts familiar with the issue said on Monday.

The experts, who declined to be named due to the sensitivity of the issue, said it was a potentially serious problem likely to cause more delays for the Russian-built Bushehr plant, which has yet to start injecting power into Iran’s national grid.

“I think what happened is that the pump failed but it didn’t just fail, it broke up, so that … there are pieces of metal that are now circulated throughout the primary cooling system,” one of them said.

Of course it’s just speculation and no one will actually admit that the pump disintegration was cased by Stuxnet. However, a pump like this would normally give some manner of warning to the operators that the pump was malfunctioning, this one didn’t, it continued to run until it “broke up”. Coincidentally, Stuxnet was designed to cause precisely this type of damage, with no warning, to industrial equipment. Believe it or not.

/in any case, with tiny pieces of metal strewn throughout the reactor’s cooling system and possibly contaminating the nuclear fuel rods, this mess is going to take quite some time to clean up and then it just might happen again
