Nuclear Disaster In Japan Could Have Been Mitigated, Say Industry Insiders
Hugh Pickens writes "Some insiders from Japan's tightly knit nuclear industry have stepped forward to say that Tepco and regulators had for years ignored warnings of the possibility of a larger-than-expected tsunami in northeastern Japan, and thus failed to take adequate countermeasures, such as raising wave walls or placing backup generators on higher ground. 'March 11 exposed the true nature of Japan's postwar system, that it is led by bureaucrats who stand on the side of industry, not the people,' says Shigeaki Koga, a former director of industrial policy at the Ministry of Economics, Trade and Industry. Eight years ago, as a member of an influential cabinet office committee on offshore earthquakes in northeastern Japan, Kunihiko Shimazaki, professor emeritus of seismology at the University of Tokyo, warned that Fukushima's coast was vulnerable to tsunamis more than twice as tall as the forecasts of up to 17 feet put forth by regulators and Tepco, but government bureaucrats running the committee moved quickly to exclude his views from debate as too speculative and 'pending further research.' Then in 2008, Tepco's own engineers made three separate sets of calculations that showed Fukushima Daiichi could be hit by tsunamis as high as 50 feet. 'They completely ignored me in order to save Tepco money,' says Shimazaki."
Any disaster could be averted with extra millions and millions spent on it, it's just balancing risk and reward.
Come on, don't be dense. The claim here is precisely that they weren't balancing risk and reward - they were overweighting their own immediate gains and underweighting the future risks, which were mostly to other people.
there's a big difference between a crank somewhere in the wide world, and your own engineers that you hired for their expertise related to your enterprise.
true nature of Japan's postwar system, that it is led by bureaucrats who stand on the side of industry
Not just in Japan, but everywhere. Bureaucrats and politicians are in the deep pockets of corporations and don't give a rancid wet fart about "The People" - then they spew so much bullshit at The People to get elected.
In economic terms it is called "externalizing". Shifting risk to others is the hallmark of capitalist economies. The same is true of any enterprise. If you have a risk, find a way to shift the cost onto someone else. The public is always a good place to shift the risk to. If you get caught with your pants down it is easy enough to declare bankruptcy and emerge a "new" entity to continue shifting the risk. These plants aren't going anywhere and given today's energy demands will be up and running in no time.
This is a sig. This is only a sig. Had this been an actual sig you would have been informed where to tune for more sigs.
After the fact there's no shortage of people telling you they told you so.
But if somebody tells me a grand total of 13 different backup-generators dotted around the site and five battery-backups might all simultaneously fail due to various reasons he would have an extreremly hard time convincing me.
Engineer or not, if his story depends on assuming a whole chain of unlikely events I'm probably not going to believe him. It's just human nature.
But if somebody tells me a grand total of 13 different backup-generators dotted around the site and five battery-backups might all simultaneously fail due to various reasons he would have an extreremly hard time convincing me.
Replace "dotted around the site" with "all the in the same basement". And the depletion of all battery backups again was not independent, with a direct causual link both to the upstream generator failure, as well as the disruption to roads and infrastructure which delayed the arrival of additional resources.
http://www.blog.voximate.com/blog/article/1058/failover-backup-systems-redundant/
"The risk analysis may calculate the risk of each backup generator failing and then estimate the risk of all of them failing simultaneously by multiplying each generator’s risk of failure together, concluding that the risk of them all failing simultaneously is statistically very, very low. However, such an analysis assumes that the backup generators are all independent systems. As this crisis has demonstrated, the backup generators were NOT independent of each other. Because they were all in the same coast-side, sea level location, they all shared the common vulnerability of being shut down simultaneously by the same tsunami. Therefore, the actual risk of them all failing simultaneously due to a tsunami was equal to the risk of a single one of them failing due to a tsunami. Since all thirteen backup generators in actual fact failed when hit by this tsunami, the risk that each backup generator would fail when hit by a tsunami of this size appears to have been 100%."
Stop being afraid of nuclear.
Deaths per terawatt-hour for all energy sources
I live in the Netherlands. We have two nuclear powerplants here, plus a bunch of them close enough in Belgium and Germany. If one of these plants has a serious accident, it could harm millions of people. And even if it isn't a medical problem, as we might be able to move all those people to safer places, the socio-economic problems will be enormous, and the problems we're facing with Greece now will be small compared to this. Look at Japan, where they considered evacuating Tokyo last year. They didn't make this public until recently, but think about that. What if they had to leave Tokyo and stay out for the next 50 years?
There is no other energy source that can create problems on such scale in such a short time.
Especially those of us living in Japan. Nothing new in this article.
I live about 90 miles from the Fukushima plant and yes, this affects me greatly. About 100,000 people are still living in temporary housing. The economy is in shambles. Our business electric rates are about to skyrocket up 17% and gasoline is about US$6.65 a gallon. With only two reactors online in the entire country, our power situation is going to get desperate if oil costs continues to go up.
It will take a decade to rebuild, and where exactly do you rebuild? The same place, just to see it destroyed again?
You want a real story? This earthquake was not a once-in-a-millennium event. Here is an article from National Geographic about a massive tsunami in the same area in 1896. That's about 100 years ago, not a thousand years ago!
Let's face it, humans are stupid. Particularly the one who "govern."
We're lucky that no one was killed in Fukushima, but our luck ran out on earthquakes and tsunamis. We still have quakes almost every day, and for the first second or two, we don't know if it will be another big one.
Every bad event could probably have been mitigated. Hell, my first marriage could have been mitigated, and that was a rotten disaster.
consider this : if any of these in Holland/Belgium/Germany/France have an accident on fukushima scale, the economy of about 50 million people would be destroyed; taking the rest of the world's economy down with it.
Yes, I'm left. You have a problem with that?
The fun fact with this accident was the number of people telling you so BEFORE the accident...
And the number of idiot saying it was a 1 in a 1000 year event... while the last huge tsunami at this place was 1100 years before... AND SO WAS FOOKING OVERDUE. And when you check with the previous tsunami in 889 (around) it's exactly the same extend and the same level of flooding.
So it's not even telling so before...
It's just looking back at the previous shrine comemorative of the event and going back to the drawing board...
The bigger problem is that these irresponsible bean counting punks discredited the whole nuclear industry. Areva should ask compensation from Tepco because of potential reduced business opportunities.
It is not restricted to capitalist economies.
Have to remind people that Chernobyl, still ranked as the world's worst nuclear disaster happened in the Soviet Union.
Wait for the first Chinese nuclear accident and it will be a whopper. Somehow they managed to copy technology from the West yet stripping out safety measures that exist, aka the high speed train technology they stole from France, yes improperly implemented and stripped out safety features.
Let's not forget this kind of thinking and denial was present at the Chisso Corporation, with the mercury poisoning scandal during the 70s in Minamata, Japan.

And this disaster is costing Tepco and the Japanese government at least Billions of dollars, quite possibly upwards of a Trillion dollars when all's said and done.
If I were an owner, I'd rather like to protect my investments from Billions of dollars of permanently destroyed plants, cleanup and damage (property and potentially health related) claims by making a few millions of dollars of investments.
For every penny they saved before, they are spending hundreds of dollars now.
Obviously the risk was that they lost their entire investment, and then that very thing materialized. What can happen here is a sort of delusion, where the assessors of the risk only see the reward, and not the actual risk.. even to themselves. That's why you need objective third parties, even when the risk is only to your business. The fact that there were lots of other people being risked only makes the inability to actually assess risk properly that much more dangerous.
Your measure of merit for equivalency (deaths per terawatt hour) is dubious.
Only TEPCO's nuclear power stations suffered heavy damage by tsunami in Tohoku's coast. Japan Atomic Power Co's Tokai NPS and Tohoku Electric Co's Hamaoka NPS survived the quake and tsunami with minimum damage. Hamaoka survived despite being closer to the epicenter, and Tokai NPS didn't get much damage thanks to heeding the advice of experts in 2006-2007 that said their seawalls were too low for the tsunamis that could affect the coast and raised them. TEPCO did nothing. It was TEPCO's regulatory capture and negligence what made this ecological and economic disaster to happen.
Mexico: 100% conservative's America now!
Oh, but people aren't allowed back to Fukushima or the surrounding area not because of the tsunami. It's because of the reactors were left without cooling too long.
People are not allowed back to Chernobyl area because, in the end, the reactor was left wihtout cooling for too long.
See a pattern here?
It's not the tsunami's, or crew making 'human errors', it's the inherent nature of the reactors to go critical and melt when left without cooling. And there's more ways for that to happen than any engineer has ever imagined... even algae growth in the seawater used for the secondary system can force the engineers to shut down the reactor before they run out of cooling water...or heat wave that preheats the same water.
So many external parameters completely out of the control of anybody.
All I see in your post is a bunch of "ifs", "mights" and "maybes".
Your brain seems to be operating on nothing but ignorant fear. Proof of this is when you said: "There is no other energy source that can create problems on such scale in such a short time."
Hydroelectric dam failure has already created worse disasters in a smaller amount of time. Coal slurry pond failure has also already created larger disasters in shorter periods of time. Normally operating coal plants are creating a larger disaster over a larger area over a longer period of time as we speak. Even if you count the deaths in Hiroshima and Nagasaki, nuclear energy has killed fewer people per TW/h than any other source of energy.
You seem to show ignorance of both nuclear and conventional energy sources. Your lack of insight and understanding have created a preference for larger assured disasters that you can understand easily over smaller possible disasters that are difficult for you to understand.
I would recommend you inform yourself and reexamine your opinions.
Deaths per terrawatt hour is not a useful metric. Even if that number is certain to be higher with everyone favorite whipping boy, coal or oil, natural gas, solar whatever there is very little that can go wrong with those which would render a large area unlivable all at once. The deaths and health costs they create are spread over time. Society can budget for and deal with those costs and even cope with the occasion colamity.
With neuclear on the other hand the absolute costs might be less but the potential to have bear them all at once exists and it could very well be a back breaker for any society, that is the prespective you have to use.
Think of it like this cancer will over time do more harm to your body than a bullet but you can live with and treat most cancers for a long time, that might not be the case with the bullet.
Repeal the 17th Amendment TODAY! Also Please Read http://www.gnu.org/philosophy/right-to-read.html
That's only true when the annual probabilities are independent. In the case of asteroids, that's probably a reasonable approximation. But tsunamis are generated by earthquakes, and the probability that you have a large earthquake in year n is not independent of whether you had a large earthquake in year n-1. When, specifically, a quake is going to happen is pretty random, but energies build over time until released.

Afaik Chinese are mostly copying Russian tech in this regard, just like they do with weapons.
Going by Wiki, this is incorrect.
http://en.wikipedia.org/wiki/List_of_nuclear_reactors#China
They've got a bunch under construction that use French tech from the 90s (CPR-1000), and then they have the AP1000 and EPR which are American and European, respectively. Finally a trio of CNP-600 which I'm not sure what they are... So definitely not Russian tech.
Thanks for piquing my curiosity, though :)
What worries me are all those reactors which will melt down if there's a full station blackout. This is a generic problem with all GE Mark I reactors, like Peach Bottom in Pennsylvania. One hour to core damage, 14 hours to meltdown. This has been known since 1972. The US still has 23 such reactors.
There have been some fixes over the years. Fukushima had the emergency venting fix, but it didn't work because, with no power, the vents couldn't be operated. The NRC has insisted that all US Mark I reactors have extra Diesel generators and pumps beyond the original complement. On at least one occasion, they've been needed.
And what I see in your posts is the disingenuous use of a very incomplete picture that considers only one statistic, the number of deaths. By that measure, Hurricane Andrew was insignificant. After all, Andrew killed only 39 people, not much more than one person going postal.
Consider instead the area of land that was rendered unfit for other uses for years. For nuclear power, that's thousands of sq km. Coal mining has been done in a reckless and damaging manner, so it could probably not be said to be zero. Then there's the contamination of groundwater by fracking. And oil spills. But we don't have to get fuel that way. For other sorts of energy, it's zero. At any time, we can remove a dam and put the flooded land back to any other use we want. You should also remember that hydroelectric generation is just one purpose of dams. They also tame floods and store water for the dry times, enabling more agriculture.
Or consider the economic costs. What will the total cost of the Fukushima disaster be? Could be more than $1 trillion. Nuclear does not do so well on that.
Intellectual Property is a monopolistic, selfish, and defective concept. It is "tyranny over the mind of man"
The "owners" are the shareholders who were clueless about the risks. Everyone told them everything was just fine. The owners trusted their assets to the "managers" who put their short term interests (profit) ahead of protecting the assets.
This is how modern capitalism works. The managers (high paid execs) get the profits, everyone else gets the shaft. (Wall street managers did very well before and after the 2008 crash... asset owners... not so well.)
I don't read your sig. Why are you reading mine?
