After Fukushima, people are legitimately worried about whether electricity can be generated safely from nuclear power stations. In Japan, in fact, regulators have just recently approved restarting some of the nuclear plants that were switched off after the worst nuclear disaster since Chernobyl.
Over the long term, nukes should be a part of a balanced generation portfolio that also includes renewables, natural gas, and, assuming that emissions can be brought within environmental standards, coal. But before the nation goes charging down the path of building new nuclear plants, the public has to be convinced that nuclear power is safe. This will require addressing two major issues that the government and the industry have utterly failed to solve, and they’re the same issues that contributed heavily to the situation at Fukushima spiraling out of control: Spent fuel and regulatory capture.
Spent Fuel. The cloud of radioactive material that required the evacuation of everyone within a 10 mile radius of Fukushima (or a 50 mile radius if you were an employee of the United States government) did not come from an explosion in the reactor’s core. Rather, the spent fuel was the problem. The explosions were caused by the loss of the heat sink in which spent fuel was stored on-site, which in turn was the result of an inability to pump water into the spent fuel storage reservoir. The tsunami flooded and incapacitated the backup diesel generators.
This same risk is present with every nuclear reactor in the United States. There are about 65,000 metric tons of highly radioactive spent nuclear fuel sitting in pools of water in dozens of nuke plants all over the country. Illinois is by far the largest storage locker for spent nuclear fuel with more than 10,000 metric tons, a consequence of Illinois being home to Exelon Generation, operator of the second largest fleet of nuclear reactors in the world. Why does this storage situation, worthy of Homer Simpson, noted nuclear engineer, exist?
The original idea was that Yucca Mountain would be the storage site for all this waste. The federal government promised decades ago that it would dispose of this waste, and the feds said they would manage it so that taxpayers would not be on the hook. Nuclear generators started paying to the federal government an annual fee which, of course, was passed through to you, me, and everyone else as ratepayers (as distinguished from taxpayers). But for various political reasons Yucca Mountain never got started, and now it’s been canceled with no replacement solution on the horizon. Consequently, those 65,000 tons of spent nuclear fuel are just waiting around for another Fukushima-like chain of events to cause an explosion that would render large swathes of surrounding territory uninhabitable for generations.
We have to solve the spent nuclear fuel disposal problem.
Regulatory Capture. The second and equally critical problem is regulatory capture, a phenomenon in which the industry to be regulated takes effective control of the government agency that is supposed to be regulating it. The officers and attorneys of regulated entities interact daily with the regulator’s staff, creating a culture of coziness that impairs the objectivity and effectiveness of the regulator.
Remember the Deepwater Horizon catastrophe? It later turned out that regulatory inspectors turned their inspection reports over to the drill rig operators themselves to fill out on their own. Talk about self-reporting. Worse, some of the regulators were sleeping – not metaphorically, but literally – with oil industry executives.
Now, I might ask you to conduct a thought experiment of transposing the Deepwater Horizon pattern to a nuclear generating station. But I won’t ask you to do that because it does not bear thinking about. It’s too scary.
Sadly, this is precisely the type of coziness that existed between Tokyo Electric Power Company and the Japanese ministry that regulated it. The nuclear industry and its regulators were likened to a small Japanese village in which the like-minded prospered by rewarding one another with lucrative positions (if you were a regulator looking at future career paths) or regulatory support (if you were with Tepco). People who dared to criticize either Tepco or its regulator were ostracized from the little nuclear village, forever shut off from promotions within the bureaucracy, much less high-paying positions at Tepco.
If you think that such things happen only in far-off Japan, then you need to learn much more about how things really work over here. Take Illinois, for example, a state that goes beyond the phenomenon of regulatory capture; Illinois has regulatory Stockholm Syndrome.
Perhaps a more rigorous enforcement of Japan’s nuclear regulations would have made Tepco place its backup diesel generators somewhere well above sea level so that they would be less likely to be impacted by flooding.
In any event, until the regulatory authorities change from lapdog to watchdog, and until concrete steps are taken to safely dispose of spent nuclear fuel, proponents of nuclear power will have given their opponents strong arguments to use against them.
