Danuta said:No, you are correct in lumping me with Dmytry. Just not correct in me ever being in the cheap seats.
I stand corrected. You are non-responsive and have nothing to add but criticism from the sky box. Thank you for clarifying.

Drakkith said:You say Hmm... like this was something big we were all missing or something. We heard about this already. What is your point? That people cover up things? Sure, it happens.
Maybe if we said Him and the people that didn't listen to him should be held accountable. Is that better?
Danuta said:It would be more honest.
Danuta said:Only he should be held accountable? He did try to spill the beans at the end. Did it work? Why not? Wasn't anyone listening? Who else should he have gone to, to get something done about it?
Hmm...
Danuta said:It would be more honest.
NUCENG said:That technique is called deflection. You have been listening to Dmytry too much. If you can't address the argument call the adversary dishonest. In all this discussion we have been telling you that integrity and focus on safety is important. What did you think we would say about someone who violated that trust?
Danuta said:Look, do you have to mention Dmytry to me in every post because it is getting annoying. What the hell? You two get a room or something.
What did I think you were going to say about the link I posted? I just asked for some comments, is all.
NUCENG said:Let's see, non-responsive, "cheap seats", "Hmmm", "It would be more honest," "Annoying."
Try adding something to the discussion other than rhetoric so I can tell you and Dmytry apart. Ooops, which one are you again?
General population are the ones who would pay for the seawall for the city. When informed, they can opt to build a seawall, or not to build a seawall, opt to have protection up to specific height, it is their choice how much they want to spend on their own safety. You don't have to impose seawall on the city because the city does not release so much radioactivity (that would affect other cities) when it is flooded.NUCENG said:Non-responsive. If I can summarize your answer You will impose absolute protection standards for the nuclear plant, but the general population will simply be told they are at risk. Really? And you call ME immoral? Your answer is that they can all die as long as they don't die from radiation.
You are switching the topic onto protection of already existing plant, which makes no sense. You are posting grossly incorrect or misunderstood numbers (ten frigging times incorrect). Forgive me if it makes me think that you're wrong and I am right.I asked you how YOU would address the tradeoffs. I said nothing about justifying anything preexisting. Don't try to put this back on me. You were faced with an initial event that I thought was the new record for a tsunami. If the record was 50 m instead of 14 m the same issue can exist. You say that it would make building a nuclear pant impossible to build in that location. The question was what you would do at an existing plant and you go off about justifying a new construction plant in the same location. In my hypothetical problem, you address the first issue of an earthquake generated tsunami and then are faced with a 1 in 5000 chance that your first solution wasn't enough based on new information. You have claimed you are knowledgeable about adressing risk. What do you do? Show me that you understand that as we learn more about risks to safety that we have to take further action. Show me that you really understand that a specific risk can not be viewed in a vacuum. Show me that you understand that protecting people from one source of risk while you ignore an even bigger risk is not the morality you speak about so much.
Instead of answering that question and showing that you understand that there are limits to how much risk we can eliminate, you choose the Kobeyashi Maru way out by changing the question and calling me names.
You sit there telling us how simple the answers are and that the reason the problems exist is that we can't be trusted. Everybody is wrong except Dmytry. That is the definition of intellectual dishonesty.
Astronuc said:The more recent event came well after the site had been up and running. On the other hand, I would have expected the government to re-assess the implications of the results on nuclear power plants located in coastal areas. Hopefully, this will now happen.
yep, at least hardened backups and electrical equipment.Astronuc said:I have been wondering about the consideration of historic earthquakes and tsunamis in the region. I must wonder what they were thinking 40+ years ago when the site was designed.
http://en.wikipedia.org/wiki/1896_Meiji-Sanriku_earthquake
http://en.wikipedia.org/wiki/1933_Sanriku_earthquake#Damage
Looking historically, it would seem that the region can expect a large earthquake and tsunami on a frequency of 1 to 2 per 100 years.
http://en.wikipedia.org/wiki/1964_Alaska_earthquake
Nearby, a 27-foot (8.2 m) tsunami destroyed the village of Chenega, killing 23 of the 68 people who lived there; survivors out-ran the wave, climbing to high ground.
Based on the Alaska quake and tsunami, it would have been prudent to perhaps design for 10 m tsunamis. But then also, the placement and design of the emergency diesel generators and fuel supply should have been hardened.http://en.wikipedia.org/wiki/1993_Hokkaido_earthquake#Tsunami (maximum 32 m run-up, but a run-up of 3.5 m at Akita in northern Honshu, up to 4.0 m in southeastern Russia and up to 2.6 m on the coast of South Korea. (ref wikipedia)

That wiki article needs correcting. The highest recorded tsunami run-up was 37.9 m (124 ft) north of the Onagawa plant.Dmytry said:edit: ahh, there
For the 2011 tsunami:
The highest tsunami which was recorded at Ryōri Bay, Ōfunato, reached a total height of 97 feet (30 m).[34]
Same location as for 1933's 28.7 meters
I wonder how high the 1933 tsunami was at Daiichi site. The quake location is fairly close (edit: hmm but not very close. could've been a lot less due to angle at which wave strikes the coast line).
Where the hell 5.5m historical maximum came from and what the hell does it mean? Perhaps it was open-sea tsunami height? That was mis-interpreted as runup height?
Well, indeed. Nonetheless, just in the last few hundred years, there been multiple tsunamis so far stronger than 5.5m, that it makes me wonder where exactly did the 5.5m figure come from.Astronuc said:That wiki article needs correcting.

Indeed... but looking at other tsunamis, the bay could of amplified a tsunami that came from other direction. It was a close call at Onagawa as it is.The Daini units have Mk II containment like FK-I Unit 6. I believe Units 5 and 6 are several meters higher than Units 1-4.
I am puzzled by the differences between the plants, and why TEPCO didn't review or re-assess the risk for FK-I.
Onagawa was somewhat protected from the tsunami wave because the bay on which it is located is facing south from the location of the large earthquake.
Yep. The risk was so high that I'm surprised they did not add protection simply to protect their own property, even if they'd neglect potential damage to other people. But the economics of safety is complicated. The existing insurance (and whatever deals they may have had with government) might be covering it to some extent.I believe we know much more about seismic activity now than 40 years ago, and in the Information Age, databases are more readily available. I do have to wonder what they were thinking 40+ years ago, and wonder why periodic re-assessments of risk were apparently not performed.
Dmytry said:edit: ahh and for the 37.9 meters...
http://en.wikipedia.org/wiki/1896_Meiji-Sanriku_earthquake
38.2 meters.
AntonL said:Regarding the design ground level or elevation of the plant, I still maintain that no consideration for a Tsumami was ever included in the design. The 5.7 metres that Tepco no proudly quote as design basis was an afterthought and result of a 2007 study
The 5.7 metre is necessary to weather waves driven by winds on top of a hurrican storm surge on top of high tide. The level is given as OP+5.7 (OP being uncovered lowest low tide), From http://www.myforecast.com/bin/tide_extended.m?city=67710&metric=true&tideLocationID=T5701" we can see already a high tide of 1.48 metres on May 19, so we have 4.2 metres safety left for waves and a hurricane surge.
The foundations of the reactor building are about 5 metres below seal level and have an intricate drainage system to pump the sub soil dry under normal operation, now this sub-soil is contaminated.
Dmytry said:...
That is just so bad :/ The worst bit is the instantiation of knowingly ineffective "water treatment" with continued emissions from 1959 to 1968 , and ostracising of the victims. How the water treatment fraud did go unrecognised for 9 years, until 4 months after the plant stopped using mercury catalyst and the commercial incentive for downplaying it had disappeared.Astronuc said:Regarding culture - or rather attitude of industry and toward industry - I can't help but think of Minimata.
http://en.wikipedia.org/wiki/Minamata_disease#Democratizing_effects
Now that's one persons opinion, which may be valid and maybe shared. But in the 1940's - 1960's, I don't believe the questioning of industry was as strong as it was after the 1960's and the evolution of the environmental and civil rights movements.
Dmytry said:"
N: First, you are right that I didn’t have the right number for a maximum historical tsunami. "
not only didn't you have right number, you didn't even have right order of magnitude.
"And you jumped on that as an excuse not to answer my question which was about engineering and management decision-making for an existing plant, and by extension government oversight of nuclear plants and responsibility for public safety. Read the problem again. The scientist threatens to go to regulators and the press. The topic of the thread was TEPCO and Government performance. You have stated your position that you don’t trust anyone, so I asked you to show how you could do it better. "
Perhaps the reason I do not trust them is because I can't really know for sure that I would do better in their shoes - haven't been in this situation - not because I am claiming I would do better? Have you ever thought about it this way? What is your point exactly - you are trying to make me self boast how i would do better, so you can then say - hey but you haven't been in their shoes?
I did not criticize their decision to do nothing about existing plant, btw. I criticized how the plant was constructed. Sorry if it is offtopic because the plant was constructed by US company. For the existing plant - well, I like to think that I would go to press and tell how regrettably this study affects my plant bla bla bla bla. I'd lose a lot of money, but I'd still have more than enough. I like to think I am good enough, but I can't claim it because I did not have to do this.
Wait. Are you saying I should trust nuclear industry more because I can't be sure even about myself? Where's the logic in that?NUCENG said:Good. That is an honest answer and I respect that. At last you are starting to see my point. I am not trying to trick you. I have been trying to get you to at least think of what it is like in their shoes. I know you haven't been there in this kind of situation and for that you should be thankful. Recognize that your distrust and fear is natural, but don't let it become an unconscious or knee jerk prejudice that others aren't trying to do the right thing. Give us the same respect you want for yourself.
I don't really need or want other people to trust me to try to do the right thing. I'd rather they use reason instead of trust. Less temptation for me. edit: and less edge for the competitors who do not do the right thing.Give us the same respect you want for yourself.
Had the similar question answered for me already. My PC used to be powered 100% nuclear. Literally. I am in Lithuania, which used to have 90% nuclear energy mix, but the actual mix here would probably be 100% nuclear most of the time.Let's get past the deficiencies of TEPCO and design flaws at Fukushima. We have to fix that as best we can.
What do we do now? How should the plants be stabilized? Is the roadmap TEPCO issued workable? What should be done at other existing plants? Should new plants be built?
Well in my opinion the cost benefit analysis would be strongly offset in the favour of the plant owner. The entire thing about families and kids who also live there - did not help with prior toxic accidents any. People have amazing capacity for self deception. There's enough pregnant women who don't stop smoking, and there used to be much more when the issue required some thinking to decide. Not impressed by reference to kids.Should Japan continue to depend on nuclear power for a significant portion of its energy production, What should we do about new plant designs and siting? Those specific topics should be carried over to other threads. Those are the kinds of challenges that engineers, managers, executives, regulators and political leaders in Japan and around the world are facing. You can be part of that decision-making process. And in my experience with the US nuclear industry your reasoned and informed input will be welcomed.
Dmytry said:Wait. Are you saying I should trust nuclear industry more because I can't be sure even about myself? Where's the logic in that?
Suppose I was sure I myself would have shot that scientist, or bribed him, or something. Then I would trust you guys even less.

Those two RBMKs had to be shut down. I don't think that was a very good decision. For all the RBMK's flaws, nobody bleeps with RBMKs for sure, and it is a very seismically stable region, etc. Also, the reactor was upgraded (with significant power derating) to minimize positive void coefficient and eliminate positive SCRAM.

You were speaking of my distrust.NUCENG said:Wait. Are you saying I should trust nuclear industry more because I can't be sure even about myself? Where's the logic in that?
No I didn’t say trust, I said respect and a little understanding. You were very close there for a minute.
Point is - no reason to trust random people to be better than oneself.Why? You shot him.
Well, you are appealing to trust a lot. When i make the point that reviews may not be effective, you appeal to trust.How many more layers of review, self-checking, independent verifications, regulatory revies approvals and inspections do we need before you realize that we don’t depend only on trust?
Indeed. And a very different situation. A design mistake, not lack of any tsunami protection.I have colleagues who spent a great deal of time at Ignalina helping your operators and managers to develop emergency operating procedures for RBMKs. They reviewed designs to identify deficiencies that could be corrected. I know that they came back with a lot of respect for your operators and scientists. Others worked with the VVER design to perform similar upgrades. Shutting nuclear plants down removes one type of risk. How you replace that energy creates its own hazards. That is a political and economic decision and could be another thread.
Actually the example I know to not have quitted smoking when pregnant is American. I was surprised, because in SU there was a strong anti-smoking propaganda back when in US you guys still had it as a 'controversial topic' and a matter of agreeing to disagree. Ohh the irony.This is a serious question and not intended to be insulting. I have heard all my life that the Soviet Union degraded the importance of family as a means of achieveming proletarian socialism. (right term?) Supposedly the approach was to start with the children and build the socialist utopia from those seeds.
Is that why you are denying that family, friends, and community has been the motivation and focus of civilization since we came down from the trees? What else makes life precious? I fear that is a chasm I will never be able to cross. That is a way of thinking I just don't understand and would never want to. Is that why you trust noone? Even in nature a bear sow will defend her cubs to the death.
Dmytry said:Also, on topic of good will.
http://en.wikipedia.org/wiki/Human_...the_United_States#Human_radiation_experiments
Not communist propaganda, all sourced, non-controversial, good fraction of it even admitted (very reluctantly). That's where data on the effects of radiation and 'safe' limits for infants was obtained from. According to you it is delusional to assume that human nature did not radically change in last 50 or 40 years - but for me it is merely a null hypothesis, and generic arguments, well, they would of applied the same 50 years ago. Those who forget history are doomed to repeat it.

The excuses made by the organizations involved go to show that so-called nuclear power experts have no intention to self reflect or admit their shortcomings. It was this self-righteousness -- evidenced over the years in the industry's suppression of unfavorable warnings and criticisms, as well as in their imposition of the claim that the safety of nuclear energy was self evident -- that lay down the groundwork for the accident at the Fukushima No. 1 Nuclear Power Plant.
