Fukushima: Myth of Safety, Reality of Geoscience

An anonymous reader writes "The Bulletin of the Atomic Scientists' has published a special Fukushima issue with interesting/deep/new pieces written by leading experts on the nuclear disaster in Japan. Fukushima: The myth of safety, the reality of geoscience, which shows that in the decades after the nuclear plant was built, the authorities discovered historical records that showed Fukushima was vulnerable to a giant tsunami, but they did nothing to protect the plant. But there's a globalized twist to the issue: The Bulletin has also translated these lengthy expert analyses of the disaster into Japanese. As Bulletin editor Mindy Kay Bricker explains: 'Those in genuine need of erudite analysis are, of course, those directly affected by the Fukushima disaster, the Japanese population. Stellar coverage by Western news outlets might win awards, but what is the point if those who most deserve the information never benefit from reading it?'"

      The problems in Fukushima had jackshit to do with tsunamis, and a lot to do with incompetence, greed and political pressure, during plan construction, during operation and, finally, during the disastrous handling of the incident after the earthquake. Those problems are universal problems that tend to plague the nuclear sector everywhere, because many view it as prestigious, there are "national security" concerns, the orders are large and a lot of money is swapped under the table in deals that cut various corners, etc.

      Since fission nuclear power, if done for safely and accounted for properly, is insanely expensive to begin with, and the costs multiply many times over in the case of a nuclear fuckup, coming up with better alternatives is not a bad idea.

      there is nothing wrong with nuclear technology. It, of itself, is safe.

      In short, this is a very simplistic way to put it. All I am saying is that even before the issues of technology come into play, there is the issue of having a good enough social framework to ensure nuclear safety. This is the necessary condition to get right before it even makes sense to consider the technological issues of nuclear safety, and this condition is rarely satisfied even in developed countries, as the Fukushima debacle has shown beyond doubt.

      The technological issues at hand aren't trivial either -- there is no such thing as "nuclear technology" per se, there are all kinds of reactors, built by all kinds of groups, connected to all kinds of control equipment and operated by various organizations with complex vendor relations, etc. Saying "it is safe" without context is rather meaningless.

    This isn't a reason to be worried about nuclear power. This shows that bad things can happen when political decisions override science engineering or when bad engineers don't do a good job.. At the end of the day, what you want can't override nature. Nature doesn't care about politics. This is true with many different technologies

    At this point, more people die from coal related problems every year than nuclear power. One interesting metric to compare power types is to look at deaths per a terawatt hour. http://nextbigfuture.com/2011/03/deaths-per-twh-by-energy-source.html. By this metric, nuclear power is one of the safest forms of power out there. The primary reasons that nuclear power stands out to people is because a) it associated with nuclear weapons which makes it scary b) it is a more advanced technology which makes it seem more risky and unnatural c) when something does go wrong is goes wrong in a spectacular fashion. This last is probably the most important- humans react to how much they hear about disasters not how likely they are to impact them. This is why people are afraid of airplane crashes and shark attacks more than car crashes and heart attacks.

    Unfortunately, few people are likely to pay attention to this. We are already seeing the fallout as Germany and other European countries turn away from nuclear power. France right now is being surprisingly calm in continuing to use it. Unfortunately, there's some indications that this issue is also making people more worried about fusion power. There's been a long-running problem with scientifically ignorant environmentalists who don't understand the difference between fission and fusion. A lot of them have tried to protest fusion research in the past and Greenpeace has an anti-fusion stance. http://www.theregister.co.uk/2008/10/22/fusion_greenpeace_no/. The whole situation sucks.

      This story that coal kills more people than nuclear is rather misleading. The issue is much more complicated than simply counting deaths --- though, of course, coal is no nice energy source at all.

      The problem with nuclear disasters like Chernobyl and Fukushima is that they leave large portions of land unusable for millenia. (besides having the risk of killing lots of people too.) The effects are not just to the poor people who work on those plants (just as the poor miners) but that they leave a severe risk of exposure for many generations to come. The cost of maintaining those patches of land unusable are very large. Much larger costs than even those needed to keep an undamaged power plant secure beyond its productive life; this is already so high that no private company wants to do it without support from large government subsidies (besides they are all helped by not being help legally liable for any accident).

      So, even though coal has indeed killed many people, that is not to say that nuclear is not a very large problem to society. In my opinion larger than coal. To support this, find out how much it costs to insure a nuclear power plant, versus how much it costs to insure a coal mine.

      Before anyone says that we need some form of energy so we must to take up these risks, let me say:
        * direct solar source
        * increase in efficiency of use
        * and please keep the population down.

      Wind turbines suffering blade failures and ice throws have killed many people, more per MWh generated than nuclear has. Consequently, France has established 500 m exclusion zones around wind turbines, where people are prohibited from entering. Germany has a 600 m exclusion zone. For a given amount of average MW generated, the area of this mandated exclusion zone for wind farms far exceeds the evacuation zone caused by the Fukushima accident. You can reduce the size of the exclusion zone by putting turbines closer together, but it's still far worse than nuclear.

      The Fukushima plant had a nominal production capacity of 4696 MW. Multiplied by nuclear's average 90% capacity factor and that's 4226 MW average for the year. It currently has a 20 km evacuation zone, and let's ignore that roughly half of that zone extends over the sea. A 20 km radius encompasses an area of 1257 km^2. So the evacuation zone (which is by no means permanent, nor likely to be permanent) works out to 0.297 km^2 per MW average.

      The largest wind farm in Europe is Whitelee Wind farm in Scotland. It has a nominal generating capacity of 322 MW. Onshore wind typically has a 20%-25% capacity factor, but Scotland's winds are strong and consistent, yielding an average capacity factor around 40%. So that's 128.8 MW average for the year. The farm covers 55 km^2 in a 13x8 km rectangle. Add a half km exclusion zone around the periphery and you get a total area of 76 km^2. So its exclusion zone works out to 0.590 km^2 per MW on average.

      So just the regular operation of the largest wind farm in Europe renders about twice as much land uninhabitable as the second-worst nuclear accident in history, MW for MW. Hydroelectric dams create a lake behind them, rendering that land uninhabitable. Itaipu dam has a 1350 km^2 reservoir. It generates 91.6 TWh annually, which works out to 10449 MW on average, for an uninhabitable area of 0.129 km^2 per MW average. Solar (pretty much the most expensive power source) actually fares well by this metric. At 125 W/m^2 and a 15% capacity factor, it weighs in at a featherweight 0.053 km^2 per MW on average.

      But wait, we looked at pretty much the worst case for nuclear, while looking at average or better-than-average cases for other technologies. What happens if you look at nuclear on average? After all, the vast majority of nuclear plants have operated safely for decades. The world's nuclear capaicty is 351 GW. The evacuation zones around Fukushima (20 km) and Chernobyl (30 km) work out to 4084 km^2. The average land area rendered uninhabitable by nuclear works out to 0.012 km^2 per MW on average. In other words, nuclear is the technology which renders the least amount of land uninhabitable per MW generated. If you replaced all nuclear power with solar, you'd render 4.6x as much land area as Fukushima + Chernobyl uninhabitable. Hydro would be 11x as much. And wind about 51x as much land area uninhabitable (about 100x for a more typical wind far than Whitelee).

      Bingo! We don't make it safe. And when we have problems, we either blame it on the press, or tell people that they are stupid, and make up excuses fro the accident.

      A big hint to the pro-nuc's (which I am one) is that the accident at Fukishima is not a nuclear fault. This isn't an excuse - it's a fact. It is the fault of a stupid decision about tsunami heights - there have been several tsunami that would easily top their walls. Then their emergency generator plan was criminally inadequate. Locating the plant along a river above historical wave ingress and height, plus a 100 percent safety margin, and this disaster would never have happened. But it did happen.

      The problem, safety wise, is that nuc energy is has a very high energy density. As energy density goes up, the consequences of release problems goes up. So even without radiation issues, a breach with that much energy involved is going to be very messy.

      But the consequences end up being the same, whether it's "unsafe nuc", or stupid designs. We can design to contain that energy density. Will we?
