They would probably put up with more than we would; but if our roles were reversed, I know most people here would be begging to have their reactors back (just not sure what we would miss first, the power for our AC, or to charge our iPads).

My bet is when their refrigerators stop running and they get warm beer and spoiled food out of them.

Chernobyl was in 1986, once every 25 years is not same as once in a lifetime.

Chernobyl was caused by human stupidity. Should every technology be shelved because people are stupid and corrupt?!


This world is doomed.

Tell me what would have happened if the Fukushima plant was coal powered.

What would of happened?

You would be whining about how all coal power plants should be shut down because they pollute the air and the 40ft wave that hit the plant released toxic contaminates on site that tainted the local water table.

Fact is Japan is in danger of another 9+ EQ and massive Tsunami, so any reactor on the coast is in danger should not be operating. Another 9+ EQ could hit Japan any day without warning.

Yet there is also this other fact that Japan doesn't have the massive natural resources to fulfill their electrical power needs without nuclear power.

Technology is a nice word for describing the miles of exclusion zone at Fukushima. Who would possibly oppose 'technology'?!

Why is this a negative thing? There will be more nuclear resources available for other countries to prove a safer / more effective means of managing nuclear power. Then Japan can later decide to follow in their footsteps.

There's nothing wrong with them taking a step back, removing their old industry, and reassessing the situation at a later date.

It's possible that this is s serendipitous decision. Despite an apparent cultural regression, as evidenced by their game shows , japan has always been able to conquer adversity. I can see japan making a decision to research, develop,implement, and market economical alternatives to all their current energy problems. Since the hard part would be done and they would not be sabotaging their own fossil fuel production business, they could easily expand to the global market. That could be THE energy game changer.

You could always lead by example by unplugging your computer, iphone, ipad, etc permanently.

We aren't in that situation. And I spent 30 years of my life without a car so I feel confident my carbon footprint is much lower then most. I notice that is a trick of the rightwing who would be the ones to refuse lifestyle changes (god gave us the right to use the planet).

Makes people like you make stupid comments is what you really meant.

Japan has the best earthquake/tsunami warning system in the world. Japan was highly aware of their earthquake danger and highly aware of the dangers of radiation. They thought that through superior engineering, high design standards and strict adherance to what the "experts" thought as more than adequate safety protocols was sufficient. Real life proved them dramatically wrong and they now have to deal with the aftermath of three nuclear meltdowns.

I don't blame them at all for making that tough decision. I do question our decision (by default) to proceed ahead as is here with far lower design standards and implementation.

Yes it can and will someday happen here, with a far greater degree of probability.

Natural disasters are unpredictable unless they manage to dig up a fortune teller somewhere. And if they get a couple of minutes warning what are they going to do? Fold up the plant and move it to somewhere safe?

This may have been asked before but what about the design of a nuclear power plant makes it so it cannot power itself?? I don't understand this.. why can't some of the power it produces power its own pumps?

During the normal operation of a nuclear reactor, there is an accumulation of many man-made radioactive materials such as iodine-131, cesium-137, strontium-90, plutonium-239, and many others. These radioactive byproducts continue to produce a lot of heat, even after the reactor is shut down, because radioactivity cannot be stopped. Unless the decay heat is removed as fast as it is produced, the temperature will continue to rise, eventually damaging the fuel and letting radioactive gases and vapors escape. What happen when something goes wrong with the water supply? Melt down

Then you need to explain this point to JStorm because my response to his post was based on JStorm pushing a hypothetical.


And I spent 30 years of my life without a car so I feel confident my carbon footprint is much lower then most.

I'd wouldn't be so smug If I were you because if there was a serious audit conducted on your actual (rather then self-assumed) carbon foot print it probably would not be far off from the norm considering all the items used in society which have or are in part manufactured with oil by products.

I notice that is a trick of the rightwing who would be the ones to refuse lifestyle changes (god gave us the right to use the planet).

Which translates to the leftwing wishing it had direct say on the lives of individuals whether they agree with their views or not.Thus there goes that whole lie of the left being in favor of "personal freedoms".

In any significantly unusual event a plant's safety systems will automatically scram the reactor (fully insert control rods) and cut steam to the turbines to isolate the reactor in case of damage....continuing to run the reactor in a damaged state could make things far worse. Off site and/or backup power then kicks in to run the critical systems and cooling loop to manage the decay heat still being generated by the core. This is what happened at Fukushima until the wave hit and took out the diesel generators and damaged electrical switchgear that made it impossible to power the cooling system after the emergency batteries failed.

Modern designs have greatly expanded the passive safety features of nuclear plants. In the new Gen III+ reactors this accident would not even have been possible.

Yeah, it should be noted that when these were built (50s-60s) they had a huge demand for cheap energy (couldn't plunder manchuria for hydrocarbons anymore) and didn't have the petrochemical deposits to lean on like most of the world does. BWRs were the cheapest way to make electricity for them on a c/kwh basis so that's what they chose. But they definitely should have replaced them decades ago, it would hurt financially but they're one of the largest economies in the world so they could ultimately afford it. Of course, the US is still using a lot of old reactors as well....

You can easily shut it down without external resources, you just cannot keep it cool after you do. You need power to run the pumps. This power has to come from somewhere, and it was supposed to come from diesel generators. However, these generators were under water.

How high should the protection be, 1,000 feet? You know, just incase an asteroid hits the Pacific Ocean? That is what I mean, you build it to a most likely scenario, then a little safer. You cannot protect against everything. Simply not possible.

All it would have taken for this to have never been an issue is for the generators to have been wave-proof. It would be pretty feasible and not that expensive (compared to the total budget of a nuclear plant) to have the generators housed in a sealed concrete building, with large tanks of diesel/lng/whatever either in aboveground tanks or flexible underground tanks sufficient to run a couple of large generators (hell I bet even one medium-large commercial generator would be able to provide enough pumping capacity to cool most plants). Slap a couple of intake/exhaust stacks, and remote automation and controls, and none of this would have ever made the news


It wouldn't take very much engineering or money relative to the scale of these projects to ensure that much at least.

This is absolutely stunning to me. Japan is about as high-tech a society as you'll find, and is now shutting down all nuke plants, and talking about phasing them out permanently. That's absolutely mind boggling.

http://www.msnbc.msn.com/id/46676913/ns/world_news-the_new_york_times/

I understand why residents would be scared or wary of nuclear power, but to take a step backwards toward fossil fuels from existing nuclear power plants? That's crazy.

Stupid is as stupid does.

They fought and lost a war over oil and resources. Now they are planning to do it again? Just too stupid.

I agree their plants should be replaced with newer and safer models. However people advocating that Japan do away with all use of nuclear power can be pretty much ignored as their views are irrational and not inline with the reality of the energy needs of modern Japan.

Furthermore for all the fear mongering about nuclear power many people ignore the vast amounts of untreated human waste, massive amounts of chemical contaminants and other material waste (garbage, debris etc) which was released into the ocean and spread around coastal areas when Japanese coastal towns were washed away after the Tōhoku tsunami. Yet you don't see these same concerned individuals advocating that the Japanese abandon are their coastal settlements which could be washed away again in another potential future Tsunami disaster and again pollute the environment.

It's always good to read more articles on Fukushima one year later.

http://www.spiked-online.com/index.php/site/article/12227/

Not a single person has died because of exposure to radiation as a result of the Fukushima accident, though two plant workers did die in a flooded basement room as a direct result of the tsunami. But lesson four is that overreaction to a problem can be worse than the original problem. For example, it was reported that 45 patients died after the botched and hurried evacuation of a hospital in the Fukushima prefecture, and this was not the only such case. One centenarian committed suicide rather than be forced from his home in the exclusion zone.

http://www.guardian.co.uk/environment/blog/2012/mar/09/fukushima-thorium-nuclear-power-uranium

To try to use Fukushima to justify a complete disavowal of the use of nuclear power would be a gross distortion of the extent of the threat it posed. It would also consign the world to greater use of fossil fuels and higher concentrations of greenhouse gases, unleashing many more natural disasters with huge loss of life. This is the real risk we need to be vigilant against.

That's well and good, but there are hundreds of reactors operating now that are going on 50 years old. Old equipment and containment buildings can fail more readily, pipes can leak or burst, a cooling water supply could dry up in a drought, backup generators could go down, or maybe something else nobody thought was possible actually happens. Whenever the fit hits the shan, the world has yet another huge problem.

With a major meltdown/radiation release happening every 20 years or so on average (plus all the little leaks where they assure us "there is no danger to public safety"), they really don't have a very good track record as a whole. They're ticking time bombs. Most of them have served us well, but now they need to be phased out ASAP.

I'd rather see their output replaced by as much wind and photovoltaic as can be manufactured, but newer passively safe (we hope) reactors probably will also have to be part of the picture. That still doesn't answer the question of how to safely deal with waste fuel, so the stuff will continue to pile up, but as has been said: pick your poison.

IMO, it's too, too, too risky to keep operating inherently dangerous reactors indefinitely, so if we MUST do nuclear, lets minimize the risks and start getting rid of 40+ year old reactors right away. I really don't care what it costs, because the cost of NOT doing it is too great. Apparently, a vast majority the Japanese population feels the same way, and I can't blame them one bit.

They did have the diesels wave proof...just not super duper high wave proof. How high should the wave proofness go? 50 feet? 100 feet? Still not high enough:

The earthquake triggered powerful tsunami waves that reached heights of up to 40.5 metres (133 ft) in Miyako in Tōhoku's Iwate Prefecture,[15][16] and which, in the Sendai area, travelled up to 10 km (6 mi) inland.[17] The earthquake moved Honshu 2.4 m (8 ft) east and shifted the Earth on its axis by estimates of between 10 cm (4 in) and 25 cm (10 in).[18][19][20]
http://en.wikipedia.org/wiki/2011_Tōhoku_earthquake_and_tsunami


There are just some things you cannot really plan for. 133 foot high waves and a city being moved by 8 feet in one moment are some of those things.
