Stuxnet found in Japan in October - Is Fukushima an unintended consequence of Israel's hacker attack against Bushehr?
According to the security company, the virus is designed to target a German-made program often used in systems managing water, gas and oil pipelines. The program is used at public utilities around the world, including in Japan.
Here is a nightmare scenario for you.
4. As the above article documents, Stuxnet was in Japan last October, presumably still spreading and intended to wreck nuclear power plants. Here is another story about Stuxnet being in Japan and infecting computers last October.
6. The head of the IAEA only last month warned that Stuxnet posed a threat to all nuclear power stations around the world! And Fukushima uses the Seimens controllers Stuxnet was designed to interfere with!
So now the difficulty the Fukushima nuclear plant operators faced in recovering control over their runaway reactors takes on a darker significance. Remember that the first problem following the quake was that the automated shutdown systems failed to operate at some of the reactors, because pumps failed and valves would not open even while running on batteries; the very sorts of mischief Stuxnet supposedly was designed to cause at Iran's power station.
Did we all just get hacked to death by Israel?
Would anyone reading this in Japan please forward to the Fukushima managers.
Why the Stuxnet worm is like nothing seen before
...It is the first piece of malware so far able to break into the types of computer that control machinery at the heart of industry, allowing an attacker to assume control... In the worst case scenarios, safety systems could be switched off at a nuclear power plant...
...the equipment used in an industrial process is controlled by a separate, dedicated system called a programmable logic controller (PLC) which runs supervisory control and data acquisition software (SCADA).
Stuxnet exploited four vulnerabilities in Microsoft Windows to give a remote hacker the ability to inject malicious code into a market-leading PLC made by German electronics conglomerate Siemens. Read more

Similar problems occurred at the Daiichi plant. Units 1, 2 and 3 were operating at full power but shut down on the earthquake. They too were flooded by the tsunami and lost their sea water pumps - but this was exacerbated by the loss of emergency diesels as well. One factor in this could be that the Daiichi plant is at a slightly lower altitude than Daini, making the tsunami relatively more powerful.
This meant that heat was building up in the power plant in the same way as at Daini 1, 2 and 4, but that core cooling sprays could not be powered.
At Daiichi 1, 2 and 3, the steam-driven HPCIs were left as the only cooling system, which eventually heated the units' toruses to the point that they stopped working. Pressure from the reactor vessels built several times to the point that it required release. Separately, gas in the containment vessel was vented and this was enough to raise radiation levels at the site boundary to 0.5 millisieverts per hour.
Japanese officials reported that for each unit, "The behaviour of the pressure of the reactor vessel and the containment vessel, and the behaviour of the water level of the reactor were complicated. Some measurements were not possible because of failures of measuring equipment. As a result, a detailed estimate cannot be done." However, they said, the radiation signature of the releases matched a theory that a few percent of each reactor core had suffered damage.
Enough hydrogen was also produced within the reactor vessel by the interaction between water and hot fuel to cause an explosion at each unit when this was vented to the secondary containment. For units 1 and 3 this removed the top part of the reactor building. At unit 2 this may have taken place in the torus, causing damage there.
Core damage is rated at Level 5 on the INES scale, an 'accident with wider consequences'. This is applied to units 2 and 3, while unit 1's INES Level 5 rating is attributed to the abnormal rise of radiation dose at the site boundary.
After the total failure of plant cooling systems, seawater is being pumped into the reactor cores of units 1, 2 and 3 to prevent overheating and further core damage. This will likely continue for some time, although plant cooling systems may come back into operation once external power is restored. Read More
