Apart from the obvious inconvenience of evacuating the area then, it doesn't sound like they screwed up that bad. Unless it'd be cheaper than the clean up to do things differently, why bother?

Apparently the problem with Fukushima is not only the reactors, but also seven pools with 40 years worth of spent fuel rods. Apparently the world is littered with repositories like that. Who is going to clean that up? Nobody knows. How much is that going to cost? Nobody knows. The nuclear industry kindly leaves this problem for future generations.

Nuclear waste is largely a political problem. As mentioned the actual amount of waste is trivial, and there are many safe options for storage. However, due to the political intractability of building a safe nuclear waste storage facility, the waste is largely left on plant grounds, sometimes in temporary storage pools built in anticipation of the availability of an offsite options such as the now-cancelled Yucca Mountain repository.
It doesn't need to be a perfect world with people perfectly rational and competent. It only needs one country (eg Australia) to decide to cash in by allocating a geologically inactive, unpopulated region to store the world's nuclear waste and it'll be sorted.zmic wrote:well yes, I suppose nuclear energy would be OK if we lived in a perfect world where people are perfectly rational and competent.
If you need to wish away certain aspects of reality in order to defend nuclear energy, count me not impressed.
The spent fuel must be kept in storage pools for several years after being removed from the reactor, anyway, since it's still very radioactive (mostly fission products and neutron activated isotopes). Radioactivity generates heat, and lots of it. If it isn't constantly cooled for a time after it's removed from the reactor, it will heat up and melt. After 2-3 years of sitting underwater, though, it isn't all that radioactive anymore and can be moved.EdgarJPublius wrote:sometimes in temporary storage pools built in anticipation of the availability of an offsite options such as the now-cancelled Yucca Mountain repository.

It wasn't really a LOCA, was it? More like extended LOOP (loss of offsite power) and loss of diesel generators leading to extended station blackout, and ultimately the loss of LPCI by some combination of mechanisms.EdgarJPublius wrote:fires in the spent-fuel storage pools
To the best of my knowledge that never actually happened.

Actually the cost has been studied in incredible depth, it's an eternal cry from certain groups "the nuclear industry has *no idea* how much it will cost to clean up a site!!!"
but the thing is that they started saying that one decades ago and kept saying it long after many nuclear sites had been decomissoned and cleaned up. when the cost was known. they still say it.
the problem of waste disposal has also been studied in incredible depth and costed many many different ways. In the US the companies have been paying the government a share of the price of every kilowatt hour for half a century to pay for the cost of disposing of and storing waste.
the engineers sat down and planned out many many pretty good options and planned out the costs decades ago. Now of course the politicians and greenpeace memebers, many of whom are too lazy to even read those analysis cry that nobody knows the cost, nobody has planned anything and do their damnedest to increase the costs and stonewall any projects to deal with the waste. They've done so so effectively that the companies who run the plants are justifiably suing the government for failing to provide the waste storage that the companies have been paying for for decades already.

It would be really nice if spreading misinformation through the media, of any form, would be a civil offense. It might help cut down on a lot of issues.

http://www.japantimes.co.jp/text/nn20120227a2.html wrote:According to interviews and documents made available Saturday, staff from Tokyo Electric Power Co., Tohoku Electric Power Co. and Japan Atomic Power Co. asked the secretariat of the Earthquake Research Committee to alter the draft of the report at a meeting on March 3, 2011.
The report suggested a massive tsunami similar to the one triggered by the Jogan Earthquake in 869 could be spawned off Miyagi and Fukushima prefectures, they said. The Jogan quake had an estimated magnitude of 8.3 and killed about 1,000 people.
A final version of the report has yet to be released in light of the earthquake and tsunami that actually hit the region eight days later, but some members of the committee called the revelation "unbelievable."
The three utilities asked the secretariat in the Education, Culture, Sports, Science and Technology Ministry to change the wording to avoid giving people the "misunderstanding" that massive quakes similar to the Jogan quake actually occurred in the past.
In reply, the secretariat told the three utilities, "We're not changing the context but we're going to do something so it may not induce such misunderstanding."
A few days later the ministry revised the draft. The reworded version said "further study" is required to decide if massive quakes similar to the Jogan quake took place because "appropriate data are insufficient."
The earthquake was followed by a 13–15 m (43–49 ft) maximum height tsunami arriving approximately 50 minutes later which topped the plant's 5.7 m (19 ft) seawall, flooding the basement of the Turbine Buildings and disabling the emergency diesel generators[74][75] located there[70] at approximately 15:41. At this point, TEPCO notified authorities, as required by law, of a "First level emergency". The Fukushima II plant, which was also struck by the tsunami, incorporated design changes which improved its resistance to flooding and it sustained less damage. Generators and related electrical distribution equipment were located in the watertight reactor building, so that power from the grid was being used by midnight. Seawater pumps for cooling were given protection from flooding, and although 3 of 4 failed in the tsunami, they were able to be restored to operation.
In the late 1990's, three additional backup generators for reactors Nos. 2 and 4 were placed in new buildings located higher on the hillside, in order to comply with new regulatory requirements. All six reactors were given access to these generators; however, the switching stations that sent power from these backup generators to the reactors' cooling systems for Units 1 through 5 were still in the poorly protected turbine buildings. All three of the generators added in the late 1990's were operational after the tsunami. If the switching stations had been moved to inside the reactor buildings or to other flood-proof locations, power would have been provided by these generators to the reactors' cooling systems.

Since the early 1990s, it was known that the Fukushima region was hit by a large tsunami once about every 1000 years. Now, people in Japan had this weird idea that tunamis are big and destructive. It's caused by al kinds of overblown historic stories about building-high waves, and by academic geologists who like to prop up the importance of their field. The tsunami fear was further encouraged by all the media attention for the 2004 tsunami, even though it happened in a completely different part of the world.
So when the historic record suggests that a spot gets regularly hit by massive tsunamis, the public might easily start to demand all kinds of expensive countermeasures, or even the closing of plants.

No need to be snarky. Misinformation is misinformation. Again stating my opposition to such censorship any such law would still cover both covering up and exagerating risks from such things. Spread misinformation to cover up risks of a landslide if you build your amusement park? jail. Spread misinformation to exagerate risks of a landslide if a competitor is allowed to build one? jail.

Sometimes though there's blatant, clear, straightforward, factual statements which are untrue, made to mislead people but many fall into the above.

Imagine China and India consuming the way the US does.
