They were not designed to be able to resist an earthquake of that magnitude so I fail to see how it can be an failure from an engineering perspective (the fact that most plants handled it fine should if anything suggest that, from an engineering perspective, it was a success).

> RADIOACTIVE WASTE THAT IS LETHAL FOR THOUSANDS OF YEARS Honest question, isn't the fuel also lethal, and decaying it makes it less lethal? I understand storing the waste might be somewhat problematic, but is it really that hard to put it somewhere safe?
Damien, to be honest, once radioactive fuel is "in the country", as far as I know, feeding it into a reactor produces more radioactive waste than the original material. But I could be wrong about that. I'm sure some of the nuclear experts, and captains of industry, and Wall Street apologists whose jobs depend on it would be able to give you a more scientific answer ;) As far as I am aware, the safest policy for "the…

TEPCO measured radiation levels of 10 Sv in the basement of Reactor 1 in June this year [1]. In March TEPCO measured radiation levels of 73 Sv/h in the container vessel [2]. A Fukushima worker tweeted a radiation level estimation of > 1000 Sv for another part of the reactor (the endoscope used for radiation testing is only rated to 1000 Sv, so cannot be used) [3]. The radiation level next to Chernobyl immediately aft…
>...but the history since then appears to indicate that the extreme concern over Fukushima radiation is depressingly justified. If you're living in the reactor containment vessel.
Unit 4 has significant structural damage, and contains the most (and most recently used) fuel rods, stored outside the containment wall. Another 7.5 earthquake could cause a collapse triggering a fuel rod fire that could not be put out. TEPCO's plan states that they cannot begin removing fuel rods until 2013, or possibly 2014. [1]. "There is as much cesium in the fuel pool at Unit 4 as there was in all of the atomic bombs dropped in all of the tests in the 1940's, the 1950's, the 1960's, and into the 1970's."
All that is required for a catastrophic release of radiation across the northern hemisphere is a significant seismic event.
Fukushima is now classed alongside Chernobyl as a category 7 reactor event, the area surrounding Fukushima will take decades to clean up, and the Japanese Government has admitted major human error within regulatory bodies, and within TEPCO and credulous government acceptance of the Nuclear industry's unfounded safety claims. [2]
And Muller claims that "Fukushima passed the test". You can't make this stuff up. But you can call it what it is, historical revisionism by an ardent supporter of the nuclear industry.
Considering the still perilous situation, it is a breathtakingly irresponsible and insensitive article to write. Truly astonishing.

That's a stunningly ignorant risk assessment. Unit 4 has significant structural damage, and contains the most (and most recently used) fuel rods, stored outside the containment wall.

Or maybe it's just a rational one. None of what you've brought up contradicts my point. The problem isn't ignorance on my part, but rather hysteria on yours. Really, if this is the way you approach life I'm surprised you have the courage to get out of bed in the morning.
>Unit 4 has significant structural damage, and contains the most (and most recently used) fuel rods, stored outside the containment wall. Another 7.5 earthquake could cause a collapse triggering a fuel rod fire that could not be put out.
Or it could do nothing at all. You do realize they spent the first part of this year pouring concrete and putting in steel rods to stabilize that building, right? Did you think they've been drinking sake and shooting the breeze all this time?

Yes, the reactors and pools are contaminated. And it will take a few years to get all that ugly stuff into completely safe storage. And? As long as the fuel doesn't go anywhere it doesn't matter how long it takes to clean up.
>Fukushima is now classed alongside Chernobyl as a category 7 reactor event, the area surrounding Fukushima will take decades to clean up
I find it amazing people can say (presumably) with a straight face that because shares some subset of characteristics with Chernobyl that it's OMG JUST AS BAD AS CHERNOBYL!!!! It's not as bad as Chernobyl by orders of magnitude. It never was.
As far as the exclusion zone goes, it's only 20 km. Even for a country as land-poor as Japan that's not much.

You are correct that the shuttering of the plants has been bad for everybody. Power is already more expensive and another rate increase (10% or so) is imminent. The air is dirtier. The whole place is a lot more uncomfortable (to comply with mandatory energy cuts, the Tokyo office in which I am typing this very post no longer has any climate control on weekends...

Insulation is a major factor and probably a main reason why you consider air conditioning in Tokyo that important: Insulation is virtually virtually virtually, i.e. air conditioning becomes more of a necessity and waste more energy. In the winter time, on the other hand, heating in Japan is very inefficient as well. During my last stay in Japan, I was happy to see at least some new building with better insulations, that is a beginning!
Another factor are long commuting times in Tokyo, another contributing factor to energy consumption.
And there is of course always the possibility of a siesta. The Japanese have somehow a reputation for Coping with summer heat is actually possible without air conditioning. I know because I live in a country where air conditioning is virtually inexistent in spite of summer temperatures comparable to Tokyo's.

And there is of course always the possibility of a siesta. The Japanese have somehow a reputation for long and busy workdays, however, most of it is inefficiently spent office time. A siesta would therefore easily be possible or just try to be more efficient and spend less time in a warm office.
Do I like to work in a warm office in the summer? No but coping with summer heat is much easier than with winter cold … I hope the Japanese will get the priorities sooner or later right, despite the lamentable state of the country (and that began not with Fukushima). and busy workdays, however, most of it is inefficiently spent office time. I often compare the Japanese with the Italians in regard to their work ethic although the Italians at least admit that they are not efficient … anyway, a siesta at least would easily be possible or just try to be more efficient and spend less time in a warm office.

Re: The Panic Over Fukushima
#106"It is remarkable that so much attention has been given to the radioactive release from Fukushima, considering that the direct death and destruction from the tsunami was enormously greater. Perhaps the reason for the focus on the reactor meltdown is that it is a solvable problem; in contrast, there is no plausible way to protect Japan from 50-foot tsunamis." It's amazing to be able to take such an arrogant attitude.…
After a nuclear disaster, we mostly remain helpless observers. As of today, the Japanese neither fully know what actually happened and still have no idea how to deal with the Fukushima aftermath in a long-term. The same goes for Tschernobyl and many other sites with nuclear fallout and waste. Nuclear energy is like a dragon awoken without any possibility to put him at sleep ever again.

I am convinced that the nuclear power industry remains not only inextricably linked to nuclear WMD programs, but its expansion is in fact driven by the desire for the materials, technology and capability to develop nuclear weapons
Perhaps in places like Iran and Pakistan. For the last few years we've been using old Russian warheads as fuel here in the US, which is the opposite situation.

Over 15K people were killed in the quake and tsunami. On the scale of "badness", ~200 projected cases is not a scale tipper. Not to trivialize the additional projected cancer risks, just to put it in perspective.
what other industry gets to benchmark social license against this tsunami? What other unacceptable risks should be weighed up against 15,000 deaths "to put it in perspective"? On the scale of badness, how many deaths does an industry need to be responsible for until its "a scale tipper"? This is a very poor way of weighing up the very real ongoing risks and hazards presented by the nuclear power industry.
The plant did not fail because "nuclear was bad", it failed because it wasn't designed to be hit by a tsunami of that magnitude; which if the same reason for many of the direct tsunami-related deaths. With that in mind, Japan needs to get better at tsunami planning and engineering, like they generally have with direct earthquake planning and engineering.
Now, as to comparing energy producing industries, the mortality metric would be deaths per kilowatt hour; in which nuclear fares extremely well compared to mainstays like coal, even if 200 additional cancer deaths out of a "normal" 4400 for the given population are added in.

I question that conclusion. The power shortages have been quite troubling. http://news.nationalgeographic.com/news/energy/2012/03/12030... http://ajw.asahi.com/article/0311disaster/fukushima/AJ201207... http://www.bbc.co.uk/news/world-asia-18468685
I read your links. I know the audio is almost an hour, so I don't expect you to have listened before you posted. According to Mr. Corbett, who lives in Japan, the predicted shortages did not in fact materialize this summer, and in fact, a SURPLUS of power was reported. He doesn't assert that without the 50 plants currently offline there will be no power shortfall. Most of the report is about alternatives such as sola…
