Alabama Nuclear Reactor Gets 'F' Grade
GatorSnake writes "The US federal government issued a rare red finding against an Alabama nuclear power plant after an emergency cooling system failure. 'In an emergency, the failure of the valve could have meant that one of the plant's emergency cooling systems would not have worked as designed (PDF).' Does this further erode the argument that Fukushima was just an isolated incident in the 'modern' nuclear power age?"
That is exactly the problem. This is no different from the tragedies frequently encountered in coal mines. They cut corners and costs in the name of greater profits. And then when bad things happen, they say "whoops! This is an isolated incident. And we will fire someone for doing what we encouraged and even told them to do!"
The nuclear industry in the US has amazingly fearsome oversight. It happens that I word for a nuclear technology company and I can tell you first hand that "NRC" is mentioned in seemingly every business conversation with numerous and frequent meetings that involve NRC. So if the NRC didn't find this sooner, I have to wonder why. Has the government been cutting back on the NRC? I hope not and if they have, they need to reverse it and fast.
Nuclear energy is the best we have right now. But it also needs to be regulated and monitored closely. No one questions that fact.
I tend to agree in many ways. It's not entirely an engineering problem.
The real risks come as a result of our system, which is squarely rooted in human greed and fallibility. We're risk-takers by nature, and the risk/reward equation is skewed toward danger.
For example:
If I'm a CEO and build a reactor, cutting costs by attenuating the safety systems specified by the engineers (e.g. using cheap materials for failsafes, or not installing them at all), my profit goes up. I saved a lot of money during construction, didn't I!
However, if something goes wrong and my poorly implemented safety mechanisms fail, my personal risk is actually quite low. I probably won't notice an impact on my earnings, I certainly won't go to jail, and once the media is done feeding on the corpse of my disaster, it's back to "business as usual."
This is a far cry from the careful designs of the engineer, and the scenario gets played out all the time, in various disciplines (see also: BP oil spill, mortgage-backed securities, etc).
Maybe the solution is to let the engineers control the nuclear industry, soup-to-nuts, and send the MBA's packing?

It isn't just the "nuclear nuts", though they probably haven't improve the R&D supply. Properly decommissioning a plant, especially one that really deserves it, is not inexpensive, and turns a reasonably profitable(once the construction/startup expenses have been amortized or written off) baseline unit into a big cost center. There is, thus, a strong built in incentive to keep patching and running as long as possible. Best case, you can continue to use the plant as a generating asset. Worst case, if you've had to make a number of repairs that compromise capacity, it may well still be cheaper to keep the lights on and the plant "operating" than it is to tear it down.
