The proceedings are secret. But surely the most attention will be on Japan’s Fukushima reactors leaking and belching radioactivity in a disaster that may have already exceeded Chernobyl on many levels. This time one lesson of both of these worst case disasters has to be learned.
Because it wasn’t learned the last time the world’s nuclear powers convened a meeting in Vienna against the backdrop of an ongoing nuclear crisis. Four months after Chernobyl, in August, 1986, Soviet experts met their Western counterparts for an unprecedentedly open meeting to discuss the disaster.
Open amongst themselves, that is. When the doors closed for the secret discussions, it seemed that East and West emerged with a rare Cold War consensus on the need to protect their nuclear industries from their respective publics. The result was spin rather than analysis.
In the West, that meant stressing the design differences between the Soviet-type reactor that exploded and nearly all reactors in the West. To this day, talking heads discussing Fukushima repeat like a mantra: “Chernobyl would be impossible in Western reactors” as if Fukushima isn’t proving that nuclear disasters can be very different and equally bad.
Unfortunately, when Chernobyl was blamed only on the flawed reactor design back in 1986, the entire incident was deemed to hold few lessons for anyone else.
Instead of focusing on what was different, however, if they had looked at what was exactly the same, Fukushima could have been prevented. If it is not recognized now, it will probably happen again.
After Chernobyl’s #4 reactor exploded, spewing the radiation equivalent of 20 Hiroshima bombs around the globe, it is understandable that it gets all of the attention. More instructive, but virtually unknown, is what happened at Reactor #2.
When #4 exploded, it ignited many fires and the water used to extinguish them flooded the electrical systems, knocking out the power to #2’s cooling system and putting the reactor in danger of melt down. It was exactly what the tsunami did in Fukushima.
Whether from a tsunami or fire hoses, water knocked out the power to the cooling systems at both Fukushima and Chernobyl #2, and that is because both reactors’ main and back up power systems were at ground level or below.
Had the lesson of Reactor #2 been learned, Fukushima would have had waterproofed back-up power located above ground — because all current reactors of whatever design require cooling, cooling requires electricity and electricity does not like water. Nothing as dramatic as a tsunami is needed either. Fires can break out anywhere and fires are put out with water.
It is not clear why the loss of coolant incident at Chernobyl #2 never received any attention. Maybe the Soviet government didn’t tell. Or maybe the West didn’t ask. But the delegates in Vienna must take note of it now and not only to adopt critical new safety rules.
In calculating the risks of nuclear energy now that Fukushima has shaken the odds, each serious incident must be counted to predict the statistical probability of future accidents.
Chernobyl’s Reactor #2 was brought under control in two days, averting a total meltdown and how it was done should be required reading for all nuclear plant operators. Hopefully, the brave plant workers in Japan will eventually succeed in averting an even worse disaster.
But Fukushima is already too contaminated to realistically salvage and will surely meet a fate similar to Chernobyl #4: entombment and encirclement with a no-man’s land.
After Chernobyl, experts predicted serious nuclear accidents happening once every 30 years. Fukushima came five years early, probably because there are many more reactors worldwide and more to come, especially in the developing world. While the corruption afflicting many such countries may not touch the safety of their nuclear industries, I have my doubts.
Another nuclear disaster will probably happen again. Not in exactly the same way as Chernobyl or Fukushima. Each will be different. But nuclear power is not going away and the price we pay for it may yet include a few more entombed reactors surrounded by radioactive no-man’s lands. Whether they are considered an acceptable environmental price will depend.
The exclusion zone around Chernobyl has become an accidental wildlife sanctuary in the absence of people. For a small island nation like Japan, that may be too high a price.
Many lessons will emerge from Fukushima. But I hope that the experts in Vienna learn at least one common lesson from the two worst – and completely different — nuclear disasters in history (thus far): Make sure that back-up power to your cooling system is located above ground and can’t get wet.
And do factor in extreme weather from global warming.
