Along with all the other news surrounding the earthquake and tsunami in Japan, the nuclear power industry is also in the spotlight due to problems that have arisen at some Japanese reactor facilities in the aftermath of the disaster. It is still a developing situation, and there is far too much that is not known about the results to make any definitive, final statement about the matter. But this is going to trigger an awful lot of debate, and I expect both sides will use this as a case to bolster their arguments.
Let me lay out perspectives from both sides of the issue in the context of the current (and still ongoing) events in Japan and suggest that neither side is going to be able to make an ironclad argument for their side based on this evidence.
On the no-nukes side, the fact that problems have arisen, and that a completely earthquake-proof reactor cannot be built will be used as evidence to support the need to avoid nuclear reactors. Two containment buildings have had hydrogen explosions which have torn those buildings apart (although the containment vessels inside them holding the radioactive materials appear to remain intact), and the surrounding area has had to be evacuated as a precaution.
The pro-nukes side can point to this and say that these plants withstood a magnitude 8.9 earthquake, and the ensuing tsunami, and the containment vessels and other safety systems have performed without rupture. There have been no containment breaches so far, and any release of radioactive material has been fairly low.Safety is the biggest issue with nuclear power, but if safety is the criterion by which we are measuring our power sources, other sources are far more dangerous. From a safety standpoint, the Fukushima plant shows why multiple backup systems are necessary for nuclear power installations. It took an unprecedented event to push things to the point of failure that they have reached, but even at this point, there has not been a serious release of radioactive material, and the area around the plants has been able to be evacuated safely.
Ultimately, it comes down to cost. As with many other things, there are tradeoffs between design and expense, between money and security. Certainly engineers could design more and more safeguards. Should all nuclear reactors be designed to withstand a magnitude 9.0 earthquake? It certainly makes sense for any reactor in Japan, but maybe less so for France.
To evaluate the nuclear power industry soley on the performance of the Japanese reactors would, in some ways, be akin to evaluating the airline industry as a result of a crash of a 1960s-era plane. Newer, and arguably safer designs exist, though some are untested.
There are new designs for nuclear reactors that have additional safety features and better robustness. There are smaller-scale, enclosed designs which don't have the same criticality, designs that use different materials, such as thorium instead of uranium, and designs that fail into a safe state, rather than needing to have active pump cooling to control the reactor after shutdown.
Nuclear power (as currently practiced) uses a centralized system for power generation. This allows the production of great amounts of power, but also concentrates the risk. Two of the reactors at Fukushima have been flooded with seawater, which will effectively kill them from further use. That represents billions of dollars of investment lost (but in the greater interest of public safety).
Centralized power generation also allows the risk mitigation to be concentrated. Security, regulation, administration, and expertise can all be focused on a relatively small number of locations, which magnifies the leverage. On the other hand, more widely and decentralized power generation can be less susceptible to natural disasters, as well as to systemic failures.
Is it more cost-effective to have the money spent on safety systems for a nuclear power plant, or would that money be better spent on producing other equipment? Is a ton of steel better used as reinforcement for a nuclear containment vessel or as a tower for a wind turbine?
Nuclear power can seem like a "silver bullet" solution, since it provides large amounts of power without direct carbon emissions. It may be a stopgap to help in the transition away from unsustainable carbon emitting systems like coal and oil. But the long-term effects need to be considered and need to be addressed to make a fair comparison with other technologies.
Editor's Note: Speculating about an issue before all the facts are known is always a dicey proposition. This was a different article when I started writing it yesterday than it is today. Nuclear power is a divisive issue for many people, so we ask that you be reasonable and respectful in the comments. Other people have different ideas than you do, but that doesn't make them evil. If you want to join in, let's have a civil discussion, and talk about the topic rationally. If you can't see the reasons why someone might have a different point of view, maybe you should reconsider jumping in.

Those reactors have been running most of nearly 40 years - 24/7.
It's finally time they must be replaced.
However, investors and shareholders don't want much preventative expense
because it would reduce their investment profits.
Investors/owners usually don't voluntarily offer to replace something that is
still working and continuing to make a profit for them.
Fortunately, this catastrophe provides the need to replace them with
much improved new designs.. e.g. Pebble Bed, Thorium powered, etc.

Just not near tsunami prone low-lying lands.
Couldn't this have all the pumps, etc., been built up 40 feet and avoided this whole mess? Or a forty-foot wall around the whole place?

As with new advances in RE power there are continuing advances in Nuclear power, such as the use of thorium. Thorium may prove to be a the transition element in nuclear power that brings us closer to safe and resonably clean power without the need for 10,000 years of storage. It may prove that a thorium reactor can burn up old radioactive material and leave us with much less waste that is only dangerous for 500 years, while still a problem it is a big step in the right direction.
For the near future we still need(non carbon)power sources that compliment RE sources and a Thorium reactor might be a good solution.

@Joe, If we can have nuclear on air craft carriers would it be safer to have the power plant floating on a ship so it could be moved if such a problem did occur again? and, potentially power could be rerouted to places needing it more in times of emergency? why not have a barge city for a power plant? that may still not stand up well against huricanes and tsunamis but they could be relocated with forewarning and if made big enough, ride the waves or be taken out away from populations if melt down or contamination type trouble occurs... not that we wan t our oceans contaminated but, it may be a novel way around giant loss of power in disaster situations,a nd reducing contamination. It could be coal burning or some other source. it doesn't have to be nuclear I'm talking about.. contributor Joe just made me think of it.

Plus there is the issue of even getting a good design built. Most people don't know the the most expensive coal power plant build in this country is "Zimmer". Close to Cincinnati it was to be a nuke, but after a inspector went "missing" and then a lot of the weld x-ray validate test were faked, they had to switch to coal. It was that of not be able to charge power user for the money already spent on the plant.
Yes you can build safer Nukes than are out there, yes you can improve existing plant. But that all cost money, and if not forced it doesn't happen. Come on, the plant in Japan was right on the coast, in a very quake'y area. It was only a matter of time before a large wave came in. But in 40 years did they build a dike around it? No, because it cost money.

While this blog looks at the costs of making the reactor safe, there is also the cost of safely disposing of the waste. This is another matter which concerns me because a very large waste facility is being made in close proximity to my summer house in Nagano. While we have been given assurances the facility will be earthquake proof. The same was said of Fukushima until ten days ago. Nearly every inch of land in Japan is subject to the possibility of a massive magnitude 9 quake. Add to the seismic activity population density and topography make me wonder whether of not safe nuclear power is cost effective here in Japan.
My hunch is that Fukushima will not be Japan's 3 Mile Island because the Japanese feel that their lack of natural resources give them no other alternatives than to continue creating new reactors. For Japan this should be the chance to consider new alternatives. This is after all a country which seems to be an endless source ingenuity.

Go take a few deep breaths of the radioactive vapor that has been released and then tell us how "not serious" it is.

NO country has a solution yet, but we continue to create this radioactive trash...
In the US< the GOVERNMENT is - by contract - responsible for this chore - good move on the part of the powerplants and whoever makes the money!
And the question/problem remains - wher to put the trash SECURELY!!!
Unless there is an answer, ABANDON all ideas of this NOT RENEWABLE energy concept!!!
NOW would be a good time, even though it should have happened after Three Mile Island OR Chernobyl..

Furthermore we haven't accounted for the costs and safety risks associated with the waste, which is still a glaring and enormous unresolved problem. Despite huge research investment we still have no viable long-term storage solution, because there's nothing we can build that will last hundreds of thousands of years. And let's be frank, nuclear waste is a huge liability because it is one of the most poisonous forces this world has ever known and it lasts for 100's of generations. There's no way we can account for that cost and it seems horribly short sighted as it non-renwable nature would only make it a stop gap. Renewables and EFFICIENCY!! are cheaper, quicker to implement, safer, recyclable and are inevitable for the future energy production. It makes no sense to use stop gaps that cost more, have a greater environmental cost and will become obsolete in our lifetimes. .

I'm really shocked by the discussion of safety without any mention of the magnitude of the risks. What is the size of the area around Chernobyl that is uninhabitable?
Is it wise to be drastically increasing the small chances of technical or intentional (terrorist or sabatage) failure making one or more large cities or large areas of valuable land uninhabitable by continuing to increase the number of these monstrosities?
What would be the impact of a Katrina scale disaster if a city the size of New Orleans (or Tokyo or NYC) was made permanently uninhabitable? If we keep building these things its inevitably going to happen. The chances of winning the lottery are minuscule but if you purchase enough tickets it will eventually happen.
Regardless of your opinion on this issue problems like windmill blades coming off or towers falling down are clearly not relevant to this discussion.

I will lead by saying that as a nuclear trained officer aboard a nuclear powered submarine, I don't live under any illusions that this technology is bullet proof. The Navy works hard to ensure I understand the risks and how I would protect you in the worst-case-scenario situation you have heard about on the news. Also, as a result, I have a relatively low level of knowledge about the details of commercial plants' operation since they are rather different from the plants that I am trained on.
However, I think that as a group of "thinking" environmentalists, you have showed up to the argument with rather little knowledge and an awful lot of smear campaign propaganda.
If you think that people aren't talking about the waste disposal problem, you aren't reading the right stuff. It has been a central topic in the nuclear community for years, as indicated by the attempt at a facility at Yucca mountain, which actually passed in 2002, but got canceled by the Obama administration.
The amount of fear mongering here really bugs me.
"one of the most poisonous forces this world has ever known" -Joel
This is a broad brush statement with no significant meaning. It's like when a used car salesman tells you you're getting a "great deal". No frame of reference, no qualification, just good ole fashioned fear of things you don't understand.
"Go take a few deep breaths of the radioactive vapor that has been released and then tell us how "not serious" it is." -Rico
What is the purpose of this statement except to incite irrational fear? Does Rico know the risks of inhaling radioiodine? I think it is more likely that he heard, like most of us, radiation was bad for you and uses that single fact in a vacuum to call out what he perceives as huge risks to the population while not even realizing that he likely has consumed far more radioactive nuclides in the organically grown bananas he has for breakfast than the reactors in Japan ever released.
If you want to be a successful "thinking" eco-site, you should look for real information, not just the rhetoric the narrow-minded "environmentalists" are using to fight the narrow-minded "big businesses". There are people with ulterior motives on both sides of this issue, so don't just accept what you are told.
I can't really invest my time in trying to counter these point by point, I just hope to add some perspective to a pretty one-sided argument.
So I think you should look at how costly wind turbines, hydroelectric plants, and biofuel facilities are to construct and maintain relative to their energy output before you try to indict nuclear plants for their "prohibitive" costs.
Because it is important. I like hiking and animals and trees just like the next guy, and I want to keep them and us around both, but scare tactics and generalizations won't accomplish that no matter how good the science is.
Or alternatively, you could consider changing the name of the site to ecosheep. That could work too, and would take less time.

A few years ago, we had a train crash in the town where i live. Right in the downtown area. luckily no one was hurt and everything was cleaned up within a few days.
But I shudder to think what would have happened, had that train been carrying nuclear waste. All of the radio-active material has to be transported, especially in such a large country such as the usa, before it gets buried in some mountain somewhere. that's what i'm worried about. There is no 'safe' way to get rid of it.
There are better ways to get energy.
