To Nuke or not to Nuke….
Posted in Musings, News, Politics, Rant on March 15th, 2011 by MichaelикониFollowing the online “discussions” with regard to the events happening at Fukushima it seems that society is split into two groups, roughly in the middle.
On the one side you have the people who perceive nuclear energy as inherently evil and in essence “we’re all going to die”. On the other hand you have “experts” (I put this in quotation because it is at times hard to assertion the credential of someone online) who perceive the risks as overblown, if I want to step down to their rhetoric I would call them the “reactor hugger group”. The general consensus on this side has changed from: “They are much better engineered than Chernobyl and the Japanese have it all under control.” to “Well, look at how well they were engineered, they survived the earthquake and the tsunami!” or if they wanted to be really fastidious: “If a dam breaks thousands will die too!”
I think both sides have it wrong, but out of different reasons.
Let’s first deal with the con argument here.
Most of the anti-nuclear crowds argument stem from two things:
1. Chernobyl
2. Mushroom Clouds
The Chernobyl comparison is somewhat apt, although only to a certain degree. Yes, a reactor did blow up and spew it’s fuel over a large area and contaminated vast stretches around the world with radiation, but it is also true that the design of the reactor was different. This doesn’t mean that a Chernobyl like event couldn’t happen in any other power plant, but the odds are lower. How much lower? That’s the big question here.
The mushroom cloud on the other hand is completely silly. Granted, it is the symbol for the nuclear age and it is a vivid image at that. But the reality is that there never will be a mushroom cloud over a nuclear reactor unless someone detonates a nuclear bomb at a reactor. The “worst case scenario” is the Chernobyl type disaster where the fissile material gets ejected from the core and spread over a wide area. This would be known as a dirty bomb. You know, the one the US is so afraid of someone could set off in the US.
So what about the proponents?
I think here we have to split them into two groups:
1. Politicians, Internet Commentators, Industry spokes people.
2. Engineers and Scientists.
The first group tends to be either misinformed as much as most of the opponents or has a vested financial interest in keeping the Status quo and downplaying any risk.
The second group though, the engineers, had me scratching my head for a bit as I couldn’t quite figure out why they were so adamant about downplaying the potential risks. It only occurred to me on Sunday that the reasons is rather simple: If you design a technology at one point or the other you have to be convinced that you have done a good job, as close to perfect as possible. Engineering always has worked on these principals, we design something with as many safety ideas in place as we can think off, and then when something goes wrong we go back to the drawing board, identify the point of failure and find a solution from this happening again.
In essence: Engineers need to believe they are Gods of their own creation and they can and will only admit they aren’t when proven otherwise.
This is an inherit human condition: We all live our lives that way, if we wouldn’t we couldn’t get out of bed in the morning out of fear that something bad could happen to us. We get into our cars or walk down the street ignoring the dangers we are in because we realize the odds are stacked in our favour, until they aren’t.
Out of this behaviour comes the rationalization right now in the pro nuclear camp why everything is not bad, but actually rather good: The reactors survived the initial earthquake and tsunami and only later failed.
This is an interesting way to look at the current problem. The reason why we now seem to have at least two melting cores is that the power that is needed to keep the cooling going until we can fully arrest the nuclear reaction has failed. This is a condition that could happen in other places as well, with or without and earthquake and a tsunami.
The engineers and scientists who write their fingers bloody right now with this line of argument on why all the other reactors are safe (no earthquake / no tsunami) fail to understand this though, or rather, they believe in the multiple backups that they have installed at all the other plants. Unfortunately Fukushima did have 300% redundancy as well. In the eternal words of Murphy: What can go wrong, will go wrong.
Yes, nuclear reactors have triple backup for these kinds of events, but cascading failures have happened before, there will always be a risk, we can lower it, but it will always exist and to deny this is doing us all a disservice.
Risk vs. Benefit
Which brings me to the real question that we have to answer when it comes to nuclear power: Are we, as a society and as a species, willing to take the risks with nuclear power? Are the benefits we gain from using it outweighing the risks?
Nuclear technology is still “brand new” in human technology terms. We have steam power for around 200 years, we have the petrol engine for a bit over a hundred and nuclear power is only slightly older than 50 years.
In these 50 years we had Windscale in Britain, Three Mile Island in the US and Chernobyl in the Soviet Union and now, it seems, Fukujima in Japan.
Add to this dozens if not hundreds of smaller accidents and incidents all over the world and you understand that the technology is far from fool proof. We’ve decided to run a marathon before we could really walk.
What’s worse on that count is that whereas with the rupture of a dam we can see the damage right away, in a nuclear disaster we may not know for generations the true cost of the accident.
On the benefit side: Japan could not have become what it is today without the use of nuclear power. China’s growth would be much lower as well. Other places like the US, Europe and Russia also benefited economically greatly from the use of nuclear energy. There is only so much fossil fuel, rivers and landmass that we can use to create electricity after all.
To Nuke or not to Nuke?
What is needed now, globally, is a debate over the use of nuclear for energy generation. This requires homework, by both sides.
The No side needs to educate itself over the real risks that are posed by nuclear power plants. The impression of the mushroom cloud over a power plant is neither realistic nor helpful.
At the same time the group also needs to come up with a list of things they, as a whole, are willing to give up if we remove the nuclear power input, at least until we can (if ever) replace it with an alternative energy source. Just turning them off and continuing as before is not an option.
On the pro nuclear side there needs to be an end to pretending that we have the technology fully under control. Eventually there will be a disaster. No human technology is infallible and honesty from the side of the pro-atom lobby would be more than refreshing.
We also, as a species, need to address what we want to do with all the spent fuel and old reactors. This is something we will have to deal with regardless if we continue using nuclear for energy generation or not. So where are we going to put all that highly radioactive garbage?
This is not a black & white scenario regardless of how either side wants to paint it. Both sides have valid points and both sides also have valid arguments in their support. The question really is: Are we willing to possibly risk future generations for our current prosperity?
