Seems sort of revisionist to say "of course Mark I BWR's aren't safe". You know what nuclear experts were saying 3 weeks ago? They were talking about all the safety features, and the multiple levels of basically impervious containment, and how radioactive material would never get out into the environment. And here we are with a pretty serious radioactive mess to clean up (and from the looks of it it's probably going…

If you're making the argument that we more closely scrutinize 40 year old designs, you'll find no resistance here. But the problem is that using Fukushima as an argument against nuclear, is like using a car crash as an argument against transportation.

My point is they were either wrong or lying. Both possibilities are pretty worrying.

When ever I see this I realize its not really helpful. Sure all the facts are true but as I've said before you can't argue with people who are scared.

In other news a hole developed in a SWA 737 jet flying to Sacremento and did an emergency descent from 32000 to 12000 feet. Will it cause people to stop flying? Some, perhaps, but for the most part no.

When you read that someone on the freeway died driving a '72 Buick that only had lap belts and no air bags you say "gee, its great we have them now, we've just had fewer highway deaths than have ever been recorded since 1949.

The same is certainly true with nuclear power plants, if we were rational we would say, "fine" lets relicense "older" reactors on the provision they are dismantled and replaced. Have we learned a lot about building reactors? Sure, could we get rid of the older ones faster if we built new safe ones more quickly? Absolutely. But we have to either learn not to be afraid (respectful yes, afraid no) of nuclear power and radiation. Perhaps we should learn about it in school, perhaps we should provide low cost detectors for folks.

I think its part of growing up as a species.

that waste can be burned in another types of reactors. Unfortunately, because of extremely high entry barrier, there isn't much chances for these or some other new types of reactors to be developed and put into production. Ie. we stuck with almost 60 year old technology [pretty much the first generation with some slight modifications] of nuclear energy production. http://en.wikipedia.org/wiki/Traveling_wave_reactor

Doesn't burning nuclear waste just turn it into a gas or a pile of ash with the same radioactive elements? Burning is a chemical reaction, so the actual nuclei of the atoms shouldn't be changed at all.

it is nuclear "burning". The point is to have designs which produce less dangerous waste [ideally the chain of nuclear reactions should end with non-radioactive elements, yet the reality is far from ideal] or use the existing waste to produce energy from it - the "waste" of existing reactors is still extremely potent nuclear fuel as the existing, very primitive and dating back to Manhattan Project, designs are just skimming the top, easiest, portion of energy.

My favorite is mixed design - nuclear fusion core which itself may be even a bit net energy negative (and thus much more realistic in the near future) and which main purpose is to generate neutrons to burn pretty much anything "heavy" and cheap. Turn the power to the core off - the thing just stops.

Nuclear power is cleaner than coal or oil. We just need to build stronger and safer reactors. Personally I'm glad OP posted this article. Fukushima was tragic, but it didn't give everyone the right to abandon rational thought. I used to work for a state pirg banging on doors to complain about nuclear power. Spreading fear by barking "3 mile island, chernobyl" etc. Then one day I knocked on the door of a nuclear physi…

CANDU reactors are safe, in fact they have a hard time getting anything to happen on a good day. If something went wrong the worst that would happen is the reactor would stop working.

Stopping reactors is not the problem, those in Fukushima did stop properly as the earthquake struck. The problem is dealing with the decay heat aftewards.

Great. I can't drink milk, had to avoid water for a day or two, having problem finding relatively uncontaminated meat, 20 km or so of this country is probably going to be left unlivable and so on. I find it incredibly offensive to see the Americans on this board downplaying the damage from Fukushima. Mod me down all you want. I will be happy to pay attention when someone purchases land at a fair price near Fukushima…

You've drank milk and eaten meat contaminated by poisonous chemicals from coal power plants for your whole life. Not a single person has died yet from the Fukushima disaster, yet millions of people have died from ailments caused by coal power plants. Why is that kind of contamination just fine? I find it incredibly offensive to see the Americans on this board downplaying the damage from Fukushima. Perhaps we should f…

I was kind of floored by the figure cited in the article of 6000 deaths per year in china from mining alone.

I looooves me some electricity. So, even though I'm presently suffering some annoyances in my daily life here in Tokyo (sporadically contaminated drinking water, suspect milk and other foodstuffs, not enough electricity to maintain our previous standard of living, Internet outages forfuckssake), and even though I bristle any time anybody (this article's author included) ignorantly implies that we know all the bad thi…

> nuke power is the safest power we've come up with (among power sources that actually have produced a significant fraction of the power we use)

This is crucial, and is why blanket statements like "nuclear power is safe" are dangerous. There is an absolutely essential qualifier required on the end of any assertion about nuclear safety, and I'm glad to see that you put it in parentheses here. Nuclear power is the best...at scale. It's completely rational to recognize that for what it is.

I will be the first to praise the virtues of renewable energy. Solar, wind, tidal, and so on are all far better implementations to solve the problem of producing electricity. All of them, however, have a crippling fault that prevents them from reaching the potential of economics and supply that nuclear can. Importantly, that doesn't doom them -- that just means more investment and thinking is required before they can reach their potential.

Hell, renewable energy is the energy sector's Python 3. We'll get there someday, you can use it now, and it's a fabulous nirvana of harmony. Today, however, it's just a little rough around the edges, and a challenge to work with because the full support of the ecosystem isn't there. So, for now, we advise Python 2: let's split some atoms.

Watching HN's reaction to Fukushima has aggravated me at times, and made me cheer at others; it's naïveté to exclaim that nuclear power is completely safe, but a roughly equal helping of naïveté to claim that there are superior alternatives at this moment.

Buy Fukushiman land. Raise your kids there. Feed them local produce. To thy own self be true. I am not defending coal or solar or whatever. I am referring to the closed attitude of the nuclear industry. There is a huge problem with nuclear defenders in Japan who don't eat their own dogfood. You'd think they would be happy to do so since the reward is huge (improved confidence) and the risk is only 20 or more years do…

The problem with Fukushima was that it was an outdated design that should have been decommissioned. Nobody who points out the relative safety of nuclear power wants us to build more Mark I BWR's. My interest is in Travelling Wave Reactors and Thorium Molten Salt Reactors. But the problem is, when people freak out about Fukushima, they don't say "Hey! Mark I BWR's aren't safe! We should shut down those designs!" They…

The problem with Chernobyl was that it was an outdated design that should have been decommissioned. The problem with Fukushima was that it was an outdated design that should have been decommissioned. Does Mr Brown want to wait another 5 years to use the same excuse for Washington's Columbia Generating Station?

>collectively, as a society (or separately, as a bunch of disparate societies), we just might not be mature enough in our thinking to strike the right balance of precaution and preparedness to handle nuclear power as safely as it should be handled.

This was precisely my point. Why the fark CANT we come together over the singularly most important resource modern and future civilization needs, energy.

We humans are really lacking in the high-level critical thought area. For example, we have yet to formalize a civilizations hierarchy of needs. Much like the individual hierarchy of needs set forth by Maslow, all levels of biology have one.

Taking a look at civilizations then, what would be the hierarchy of needs that require nurture, protection, support etc...

I have come up with the following first attempt:

Progress

Organization

Wellbeing

Energy

Resources

Sustenance

First: a civilization needs sustainable methods of feeding itself which is not a net drain on the planet. (potentially combined with Resources)

Second: they need to be able to access, extract/harvest and refine appropriate Resources.

Third: they need to be able to produce and support the energy consumption requirements they have in a similar sustainable manner.

Fourth: They need to be able to provide for the wellbeing of the civilization through both proper physical protections as well as appropriate health care services that are not, themselves, a diseased burden on the energy, resources, or sustenance of the civilization.

Fifth: Proper methods, models and modes of organization are required -- organization of people and the modes by which they communicate and manage the other needs.

Finally: the civilization needs to progress. Review, refine, reinvent.

The problem is that with the Kardashev Scale, there is a fundamental failure to address something akin to a civilizations hierarchy of needs which must be addressed if there is any hope of evolving along this scale.

Using nuclear power as a way to awaken people to this might work.

The problem is that we are completely consumed with individual greed which manifests in the very fabric of our society to such a degree that we cannot even fix the current systems of resource/political/energy control to build consensus around a plan to evolve as a whole.

We are far to in the weeds on every single level of such a hierarchy, pulled with distractions, disinfo and FUD to make real progress.

BTW check out these pics of the reactor... I am amazed that it is as good as it is given the state of the reactor buildings. Given the fact that the spent fuel storage were in the TOPS of these structures which we now see lay in practically rubble, leads me to believe that we really do not have any clue where this really will head as we don't have concrete evidence (the outside public, not those really dealing with this) that the materials haven't simply just spilled all over the place.

hmmm, the entire article excludes the words 'weapons' and 'waste'. all nuclear reactors produce long lived radioactive wastes which are left for humanity to manage well beyond the forseeable future. Here in Australia, we've come up with a state-of-the-art answer to our own burden of nuclear waste (arising from 30 years of experimentation and research reactors) - we're building a road out to a remote desert location, building a shed and dumping the unwanted problem on the tribal lands of a disempowered, de-funded indigenous community. Real reassuring, huh?

As for weapons, although the old cold-war powers continue to slowly reduce the huge numbers of conventional nuclear weapons they hold, they're also building new ones. And at the same time as the total number of nuclear warheads in the world is slowly decreasing, the total number of actors holding those weapons is greater than ever, with the proliferation of nuclear materials and technologies spreading despite all rhetoric and pantomime surrounding the NPT. As Former US Vice President Al Gore said in 2006: "For eight years in the White House, every weapons-proliferation problem we dealt with was connected to a civilian reactor program. And if we ever got to the point where we wanted to use nuclear reactors to back out a lot of coal ... then we'd have to put them in so many places we'd run that proliferation risk right off the reasonability scale."

finally, to the question of renewables : I totally reject the repeated assertions that renewables can't provide scalable or baseload power. Here in sunny Australia, we're following the lead of nations like Spain and building a few large grid connected solar-thermal and solar-hybrid plants, that compare well with the capacities of old fossil and hydro plants. Already, large remote communities in my part of the country are powered entirely by solar concentrator arrays.

So I say, stick your nuclear power reactors where the sun doesn't shine.

"20 km or so of this country is probably going to be left unlivable" [citation requested] I haven't seen any hint of that. Is that from actual scientific reports based on sensible standards of "unlivable" (i.e., based in sensible risk analysis), or is it just based on unscientific worries? And did you have a hard time finding "uncontaminated" meat because there was actually a shortage of meat that was scientifically…

He said 'is probably going to be' not 'has already been'.

There is plenty of suggestive evidence, like the nytimes article EScott11 referenced, showing cesium 137 contamination 200% of Chernobyl levels 25 miles from the plant, or the recent Greenpeace video where they max out their Geiger handhelds 35km from the plant, that there are going to be some fairly widespread consequences to the contamination of soil by radioactive material.
