GE, the company that boasts that it "brings good things to life," was the designer of the nuclear plants that are blowing up like hot popcorn kernels at the Fukushima Daiichi generating plant north of Tokyo that was hit by the double-whammy of an 8.9 earthquake and a hugh tsunami.
The company may escape tens or hundreds of billions of dollars in liability from this continuing disaster, which could still result in a catastrophic total meltdown of one or more of the reactors (as of this writing three of the reactors are reported to have suffered partial meltdowns, and all could potentially become more serious total meltdowns with a rupture of the reactor container), thanks to Japanese law, which makes the operator--in this case Tokyo Electric Power Co. (TEPCO) liable. But if it were found that it was design flaws by GE that caused the problem, presumably TEPCO or the Japanese government could pursue GE for damages.
In fact, the design of these facilities--a design which, it should be noted, was also used in 23 nuclear plants operating in the US in Alabama, Georgia, Illinois, Iowa, Massachusetts, Minnesota, Nebraska, New Jersey, New York, North Carolina, Pennsylvania and Vermont--appear to have included serious flaws, from a safety perspective.
The drawings of the plants in question, called Mark I systems, provide no way for venting hydrogen gas from the containment buildings, despite the fact that one of the first things that happens in the event of a cooling failure is the massive production of hydrogen gas by the exposed fuel rods in the core. This is why two of the nuclear generator buildings at Fukushima Daiichi have exploded with tremendous force blasting off the roof and walls of the structures, and damaging control equipment needed to control the reactors.
One would have thought that design engineers at GE would have thought about that fact, and provided venting systems for any hydrogen gas being vented in an emergency into the building. But no. They didn't.
There is a worse problem though. Probably in an effort to keep the problem of nuclear waste hidden from the public, these plants feature huge pools of water up in the higher level of the containment building above the reactors, which hold the spent fuel rods from the reactor. These rods are still "hot" but besides the uranium fuel pellets, they also contain the highly radioactive and potentially biologically active decay products of the fission process--particularly radioactive Cesium 137, Iodine 131 and Strontium 90...
