AI Thread Summary
The discussion centers on the trustworthiness of the nuclear industry and public perception following recent accidents. Concerns are raised about past assurances of reactor safety and the industry's tendency to prioritize cost over safety, leading to preventable disasters. Participants debate the relative risks of nuclear power compared to other energy sources, with some arguing that nuclear remains a safer option despite its flaws. There is skepticism about the industry's ability to regain public trust, with some predicting a long recovery period before acceptance returns. The conversation highlights the need for a reliable energy source while acknowledging the challenges and risks associated with nuclear power.

What happens if another earthquake damages something critically important, statistically improbable right?
Er, so what? People really do consider improbable events when assessing risks.

Even better, an aberration, let's discount it!
I think you greatly misunderstand. At the risk of putting words in nismaratworks' mouth, the claim is not that we can ignore it because it's unlikely -- the claim is that can ignore it because it no longer fairly reflects the risks, due to improved safeguards against human stupidity.

Of course, people will always find new and creative ways to screw up. I refrain from judging the veracity of the claim one way or the other.

Actually the Chernobyl power plant had reactors 1-3 still operating till 2000, 1 shutdown in 96, 2 in 91 and 3 in 2000. Ignalina 1 and 2 were shut down in 04 and 09. Kursk 1-4 are still in operation. As is Leningrad 1-4 and Smolensk 1-3. With the exception of Ignalina 1 and 2 all of those reactors are RBMK 1000, the same design as Chernobyl 4. Ignalina is a RBMK 1500, just a up powered version of the RBMK 1000 reactor. As for no RBMK reactors being built Kursk 5 is a RBMK 1000 reactor and it is still under construction.
None of those currently operating plants qualify as "similar to Chernobyl" in this context, despite a similar reactor design. Design features that contributed to the Chernobyl accident were redesigned, including the control rods, fuel enrichment, and several others. Referring to them as the "same reactor design" as Chernobyl in this context is just incorrect.

Not to even mention that the reactor itself is only part of a nuclear plant.

The design changes that were implemented to the RBMK 1000 series of reactors after the accident at Chernobyl 4 were mostly to give the reactor more stability at low power, to help lower the nasty positive void coefficient of the reactor, and to prevent mucking with the automatic safety systems.

The reactors still lack the full containment structures that western reactors have. Also the RBMK reactors still have a positive void coefficient. These changes made the RBMK reactor safer but it is still essentially the same reactor.

It is akin to taking a car and upgrading the breaks and tires, yes the car is now safer, however it is still the same car.

However this is all somewhat besides my point. My point is that a reactor design that caused one of the worst accidents in the nuclear power industry, has put up 25 years of operation without another similar accident.

I know that a reactor is only the heat source for running the generators, and that there is a bunch of support equipment related and unrelated to the operation of the core. Take the reactor out of the equation and a coal plant looks strikingly similar in build. However it was the core that in the end caused the problem at Chernobyl, not the support equipment.

Yes, and I wouldn't call it hysteria. While there is certainly some of that, every argument made in favor of nuclear power for the last twenty years will serve as evidence that the nuclear industry cannot be trusted. We were told the reactors were safe when they were built. We were told that new reactors are much safer now - you know, new and improved? Which means you were selling us the old crappy stuff the first time and still operating it? We couldn't trust you before but we can now?

What really sinks this for me is the cause of the failure. It is EXACTLY the sort of lame oversight that I have talked about in the past - the reason I don't trust any form of heavy or light industry. I have seen it too many times at too many levels. Nothing about the engineering can be trusted when industry can be so incredibly blind to the weakest link.

When we allow cost to compromise public safety or common sense, this is what we get. Those generators should have been tsunami proof, not tsunami resistant. This was caused by approximately the same mistake that sank the Titanic - the lame assumption was made that the water would never go over the wall. It was a pedestrian oversight. It was completely preventable. It wasn't a matter of failed nuclear engineering, this isn't rocket science, just as we saw in the Gulf last summer, it was a matter of failed responsibility. It is an unforgivable oversight and I seriously doubt the public trust can be recaptured. The spin masters will make mince meat of the pro-nuclear position, and at this point I have to agree with them.

I know that good people with good intentions build these systems to the highest standards. I understand that it is not a betrayal of good faith. I also know that we need nuclear power. But it is true at every level of industry that the almighty bottom line challenges reason and responsibility. What caused this disaster was the need to save a few bucks, nothing more. And for that, all of the grandiose statistics and calculations go right down the toilet. What people will remember are exploding nuclear power plants. Do I want that in my backyard? Hell no!

Public perception is I think a lost cause. It will be another thirty years before the public starts to buy into this again, and by then we may no longer need it.

And the nuclear Navy's safety record is stellar. :) Yes, it's a perception issue, to be sure. Not a reality issue.

So the design was altered, in ways relevant here, but it's still the same design in the way relevant here? OK.
It is akin to taking a car and upgrading the breaks and tires, yes the car is now safer, however it is still the same car.
If we were discussing an accident caused by faulty tires, the car is not the same in the relevant way. It is the same in an irrelevant way.
However this is all somewhat besides my point. My point is that a reactor design that caused one of the worst accidents in the nuclear power industry, has put up 25 years of operation without another similar accident.
Yes, but again, the design was altered in ways very relevant to the odds of having an accident in those 25 years.

In the defense of the Chernobyl reactor design, several back-up safety measures were disabled while the idiots were running their experiment. Any improvements to prevent that aspect of the disaster would require your to make it impossible to override those safety measure. I assume that is what they did change in addition to other improvements.

Its hard to compare Chernobyl to the Japanese disaster because one was due to natural disaster and the other is due to semi-deliberate human negligence. It seems that the problem is probably more complex than just reconnecting a generator. If it was that simple surely they would have done it by now just flying in mobile industrial generators.

I'd add, in Japan you have no blast, no huge fire lofting particulates incredibly high to precipitate over europe. In short, Chernobyl was unique for all the reasons you've said, and unlikely to happen again.

This argument feels particularly weak. My parents were told that their 1960s behemoths were safe because they could survive an accident without denting the chrome. Now we're told that our 2010s commuter go-karts are safe because they crumple like an aluminum can in an accident.

Understanding of technology and (specifically) safety evolves over time. The machinery my company sold 20 years ago was safe. As safe as could be! That doesn't mean newer technology isn't safer. And it certainly doesn't mean we were lying about the safety of our older products.

When it comes to things like nuclear power plants, I'm inclined to offer a little more understanding. It's not like they get to build prototypes and test them in different types of earthquakes and tsunamis. There's an implied risk (same as building a skyscraper or a fireworks factory) and so far, it seems that nuclear power has held up its end of the deal.

This would be an interesting trade-off - and extremely unlikely. What happens if a sensor starts malfunctioning and giving false readings?

I'm not that familiar with nuclear power facilities, but a malfunctioning sensor can always be a threat to a computerized program. Garbage in, garbage out. A good, safe program responds to problems that can be anticipated, but leaves unique malfunctions for humans to solve.

Interesting difference in approaches between Chernobyl and TMI. At TMI, the emphasis was on understanding the underlying problem causing the indications operators were seeing. Instead of focusing on safing the reactor in an anomaly, the operators focused on determining and correcting the underlying problem. The solution was to 'dumb down' operations and rely more on checklists that directed actions to avoid a disaster rather than fixing the underlying problem. At Chernobyl, the attitude all along was that the operators should follow directions (via checklists or engineers) and didn't require the knowledge to diagnose underlying problems.

When you're talking about humans and group dynamics (which is almost more important than the knowledge level of the operators), there are no perfect solutions. You minimize the chance of errors, but you never get the chances down to zero.

I don't enough of the details of either situation to make an authoritative comment about either's solution, but I generally prefer relying on knowledge than checklists. Regardless, all too often, organizations focus on only these two options, since they're easy to quantify, and miss the areas where they could truly make improvements.

It's hard to train teamwork, communication, discipline, and ownership. These qualities play a more important role in crew errors than most people give credit for. The crew that defers to the engineers conducting an important test, not realizing that the engineer is trusting the crew to stop his test if it creates an situation that the crew considers unsafe. The crew that misses the underlying problem because every single person on crew is looking at the same spectacular symptoms of the problem - i.e. a lack of discipline has reduced an entire crew into accomplishing no more than a single person could. The crew that just doesn't understand what they're saying to either because so much communication is unspoken and assumed - or because some crew members are bullied and unwilling to speak up, etc.

These aren't the type of things that are ever likely to be reduced to zero. A very good organizations at least gets them close to zero, while a dysfunctional organization has chronic problems like this. Those are also the type of things that would be hard to measure during a safety inspection.

Provided you're working with a mature system, manned by people that have grown up in the system and aren't intimidated by it, the military has a culture that encourages good group dynamics.

It still takes a conscious effort to achieve that - especially in fields that deal with new technology/concepts that can be intimidating to the new operator.

And whether you're training new nuclear operators, new satellite operators, or coaching kids' soccer teams, the hardest thing to do is to get the person to 'own' the knowledge or skill they learned. To get them to quit deferring to someone that may be an expert in their own job, but knows squat about crew operations; to get them to quit deferring to the team's star and to do something on their own, etc.

I used to have to investigate satellite anomalies and they were almost always caused by crew errors. And it was rare for the error to be due to a lack of knowledge or proficiency. Most errors were due to the fuzzy arts of communication, teamwork, and discipline - to the extent that many seemed almost comic in how they developed. Those type of errors always make the people involved look dumber than they really are (but at least make for incredibly funny stories). Hence, I think it's a mistake to write off Chernobyl as being due to Russia being less skilled in nuclear operations than the US or Japan or being simply due to a less safe design.

None the less, you have about 442 nuclear reactors in the world and you've had 3 incidents serious enough to get press coverage. And this is consdering that over 350 of those reactors are at least 20 years old, so that's a lot of operating time with few critical failures. You can meet a very high percentage for reliability - you just can't get to 100%.

Sensors malfunctioning and giving false readings are not a problem. In systems where failures would have serious consequences, the usual solution is to employ something called triple redundancy. You don’t measure it once, you measure it three times. If two sensors agree and one disagrees you believe the two that agree. Techniques like this do tend to reduce the chances of serious failures to acceptable levels.

I’m not exactly sure of what is being suggested about the events at Chernobyl, but some of what is being said doesn’t accord with my understanding of it. I don’t know that there was anything invalid about the test they had intended to carry out, or the techniques to be used or any failures of ability among the actual team who were supposed to conduct it. The chronic part of the story as I understand it is that another conventional power station went off line unexpectedly and Chernobyl were asked to delay their test. The problem at the other power plant took longer to rectify than expected and by the time Chernobyl was given the go ahead the team assembled to conduct the test had gone home. There are some obvious questions about command and control structures that allowed the team that were left to take the decision to proceed with the test themselves, from there it was something of a soucerer’s apprentice situation. I suppose there are then also some valid questions about reactor control design that allowed them to keep withdrawing the control rods because of their misreading of the situation when they should have been inserting them. Isn’t there now some fly-by-wire type solution that would make that impossible I seem to recall hearing about?

You're joking right? You don't believe they just have the one sensor doing the job? That would be madness.

This is the whole point of having redundant / parallel systems. We can't trust just one system so we put a few in. The chances of them all failing simultaneously are incredibly small in comparison to just relying on one. I don't know of any critical processes that rely solely on one system without backup / redundancy / parallels.

Naturally, you can't bring that down to zero risk, but any statement such as that you made above is going for the scare factor in my opinion.

To get a better grasp of the human involvement in Chernobyl here is a, pretty lengthy, wiki article that explains it rather well.http://en.wikipedia.org/wiki/Individual_involvement_in_the_Chernobyl_disaster"

Just curious, but what is the risk of coal power and why would a Chernobyl event once a year still be lower than with coal power :confused:
I haven't been back to the thread and haven't read past this (yet) so I haven't seen if anyone responded, but according to the EPA, coal power kills about 24,000 Americans a year, with almost all of them being preventable:
http://www.msnbc.msn.com/id/5174391/ns/us_news-environment/

That link includes an interesting "experiment" that happened during a long blackout, where a lifting of air pollution was very noticeable.

Note: This does not even address global warming. While discussion of global warming itself is not permitted here, I mention it because it is many of the same environmental activists who are against nuclear power and believe in a very bad situation coming due to global warming: a contradictory set of opinions.

Regarding Chernobyl: Estimates vary, but the WHO puts the number of deaths at around 4,000 (from the wiki). In other words, every two months, coal power kills as many people in the US as Chernobyl killed worldwide.

[edit: My citation wasn't exactly right: This report was not done by the EPA, but rather by "by a consultant often used by the Environmental Protection Agency"]

re: bolding mine: This above all confuses me... that on one hand you want to save the environment from anthrogenic global warming, acid rain, etc... yet by default there is support for coal!

I sooooo don't understand that position, not even a little. Is radiation so much more frightening than lung cancer, asthmatic asphyiation, or other "fun" effects of coal? Hell, even mining Uranium can have the benefit of releiving Radon seams...

...I don't understand the anti-nuclear-by-default-pro-coal stance. There's no element of it that I understand, and I never have. Green energy is not happening right now, and it's not just for lack of funding; Pickens proved that.

I just... do not get it.

*I'm sure your sarcasm tag was on nismaratwork, however I'm still going to respond to this.

The reason for if you are anti nuclear then you support coal is because those two power sources are the only choice for cheep base load power in the USA and arguably in the rest of the world.

Even the worlds largest wind and solar projects come no where close to replacing any of the top http://www.eia.doe.gov/neic/rankings/plantsbycapacity.htm" in the USA.

So notes can be compared, here is a list of the largest power complexes by fuel type in the world.

Roscoe Wind Farm (on shore wind) in Texas, USA provides 781.5 MW nameplate capacity
Thanet Wind Farm (off shore wind) in the UK provides 300 MW nameplate capacity
Sarnia Photovoltaic Power Plant (solar PV) in Ontario, Canada provides 97 MW nameplate capacity
Three Gorges Dam (hydroelectric) in PRC provides 18300 MW (current)/22500 MW (completion) nameplate capacity
Taichung Power Plant (coal) in Taiwan provides 5780 MW nameplate capacity
Kashiwazaki-Kariwa Nuclear Power Plant (nuclear) in Japan provides 8212 MW nameplate capacity
Kawagoe Power Station (natural gas) in Japan provides 4802 MW nameplate capacity
Surgut-2 Power Station (fuel oil) in Russia provides 4800 MW (current)/5600 MW (after upgrade) nameplate capacity

Wow, I didn't realize nuclear / coal / oil / gas plants produced so much. I thought they were only in the 1 to 2 gigawatt range.

RE Bolded: That is incredible. I can only imagine the water capacity they need for that. Now there's a dam you don't want to burst.

I'm sorry, but I wasn't being sarcastic; mainly because:

1.) Hydroelectric is a bloody environmental catastrophe
2.) Lack of storage and more efficient/cheap transmission = Wind/Solar not being a viable replacement for Coal or Nuclear.
3.) Newer designs that are literally generations beyond what we have (thanks Greenpeace, I used to like you) are more efficient and capable of greater generation.

Many modern nuclear plants produce between 0.9 and 1.2 GWe. A twin unit state would produce 1.8-2.4 GWe.

Some large PWR units produce 1.3-1.45 GWe, and the Gen III+ units are up to ~1.6 GWe.

Yes, those are the numbers I'm thinking of.

According to the above though, you have a nuclear plant producing 8.2:
Kashiwazaki-Kariwa Nuclear Power Plant (nuclear) in Japan provides 8212 MW nameplate capacity

Or have I read that number wrong?

That may mean it has 8 reactors...

Regardless of people's concerns about hydro, there is a more important problem with it: it's essentially fully utilized already, so there isn't much potential for expansion.

What about the issue of biologically dervied fuels, from algae and bacteria? That certainly has enormous potential, and unlike coal or nuclear it's portable, exportable, and safe.

Personally, I trust the nuclear industry more than I trust the government but that's really not saying much.

Politicians: "People who shake your hand before an election, and your confidence after." (Ernie Kovacs)

I'm feeling rather shaken by all of this. My "love" of nuclear is really more of a loathing of coal, but this is deeply disheartening. We can't expect to scale up nuclear if that means equal scaling of contamination...

I'm disturbed, and uncertain.

Treading warily, am I read into this Nisamratwork, that you have had a road to Damascus style change of heart to the view not only that nuclear power generation is not safe, but that the nuclear power generation industry is inherently dishonest in its dealings with the public? From the links you have provided, I am failing to find the basis for that.

No, I can't claim such a conversion, and I can only speak to TEPCO's safety record, which from what I have seen is uniquely abysmal and criminal. The video doctoring incident, and their many other spills, leaks, and other "whoopsies" over the last decade+ is pretty disheartening.

As a whole, I wouldn't trust an industry that considers this some kind of norm, or doesn't react violently (metaphorically) to that level of deceptive practice.

Beyond that, I have never seen nuclear power as safe, I see it as safer than COAL/LNG. I would say that's still absolutely true, but I'm no longer convinced the dichotomy is so simple or...well... dichotomous. In that, I've had my RtD moment, yes, but not quite so grand as to deserve the appellation even in jest. I'd also say that my belief in nuclear is founded on a fundamental lack of hope in other options; I'm convinced that they exist, but not that we'll implement them.

So... self-defeating there, but I guess you could say I've converted from monotheism to monolatrism.

I don’t entirely share your view nismar, but I do respect it and accept that you probably have as much valid basis for your view as I do for mine. I would have to say, and I do not direct this at you particularly nismar, that I find no evidence whatever that you or I or any of the Japanese people local to the disaster have been in any way misled about what is happening. My conspiracy theory sensors are twitching.

Oh, I can't see that they've been misled either, but judging by TEPCO's recent history in the area, I'd be more surprised that not to see that they haven't been. Still, I think we all know those answers come AFTER they deal with Fukishimi-Daichi, not during.

The altered video is not conspiratorial (it's also not around this incident), except insofar as it's a very minor and failed conspiracy itself.

I realize that this is a HARD-Left source, but it's not agenda-based, just a good summation of TEPCO:

I suspect that Astronuc could point me to a better publication than the results of a google search, but the history here is not exactly a secret.

CNN said:
Tokyo (CNN) -- Radiation levels in pooled water tested in the No. 2 nuclear reactor's turbine building at the Fukushima Daiichi power plant are 10 million times above normal, utility company and government officials said Sunday.

Hidehiko Nishiyama, an official with Japan's nuclear and industrial safety agency, said the surface water showed 1,000 millisieverts of radiation. By comparison, an individual in a developed country is naturally exposed to 3 millisieverts per year, though Japan's health ministry has set a 250 millisievert per year cumulative limit before workers must leave the plant.

The 10-million-times normal reading applies to radioactive iodine-134 found in the No. 2 building's pooled water, according to the nuclear safety agency. This isotope loses half its radioactive atoms every 53 minutes, compared to a half-life of every eight days for radioactive iodine-131 that has also been detected in recent days.

This exponentially dwindling amount of radiation means, according to Nishiyama, that it's unlikely that sealife -- and, several steps down the line, humans who might eat once contaminated seafood -- will suffer greatly from the iodine-134 exposure.

"Certainly, we have to be concerned about the fact that the level of radiation is increasing," said Nishiyama. "But at this point, we do not ... envisage negative health impacts."

There was no indication either of harm done to the two people working in and around the No. 2 reactor when the test result became known. Those two subsequently left, and work in the turbine building has stopped until the government signs off on the power company's plan to address the issue, according to an official with the Tokyo Electric Power Company, which runs the plant.

That said, a Tokyo Electric official noted Sunday that people continued to work in other buildings -- including a control room, which got power and light for the first time in weeks the previous afternoon -- in the No. 2 reactor's complex.

Bolding mine, in case people skim and think it's 10M X outside of the reactor pool.

Read more carefully, and you'll see that it is one short-lived isotope whose concentration is "10 million x normal". "Normal" is close to zero, which is why we have it locked up.

I see that CNN is comparing mSv and mSv/year as if they were the same unit.

You think so:

"The carcinogenic isotopes that are released at Fukushima are already floating to Seattle with effects we simply cannot measure."

It's an anti-nuke propaganda piece, not a "good summation of TEPCO". TEPCO might be horrible, but the fact that wacko lefties hate them goes in their plus column.

That's only the tip of the iceberg for the nonsensical information being reported. "The surface water showed 1,000 millisieverts of radiation" is gibberish. It would be nice to see a report written by someone who has a clue what they're talking about.

I would say that statement is accurate. They cannot measure the effects because there are no effects.

Wow... at what point did a statement about radiation confined to a reactor vessel have ANY implications for Seattle?

Are you telling me that people in freaking Washington are worried? :smile:

Well it's not locked up at all of course, that's the point, but the point is also that due to the short half life and relatively benign 'daughters' these isotopes don't pose a risk to sea-life and the food chain.
