I thought that we had relatively few nuclear accidents. I don't remember a single major one since Chernobyl which was 25 years ago. And now we have a 40 year old nuclear plant that whitstood a 9.0 earthquake in good condition and only succumbed to the following 10 meters high tsunami and even now it looks like it will "only" produce a local disaster.
Chernobyl was indeed the last "major event". Thanks for reminding us that it´s only 25 years ago instead of the 100,000 years usually claimed for the chance of a next "major event" in the nuclear industry. And o/c it doesn´t mean that nuclear technology is a good and clean technology when NOT taking Chernobyl into account. There´s still a bunch of (even more serious) problems linked with nuclear power, e.g. proliferation or waste management, which BTW, hasn´t been solved in any country.
And yes, at Fukushima there´s a 40 year nuclear plant which had been built w/o taking into account the foreseeable natural catastrophes in connection with its location. It´s just by fortune that the facility withstood the earthquake in relatively good condition. Meanwhile, there´s evidence that planning did NOT take tsunamis in account[*], and for me that´s a grossly negligent fault.
W/r to "local disaster", we´ll have to wait how the whole thing develops. But as can already be seen, placement of nuclear reactors in close vicinity to a town/region with >30 million people is NOT a responsible choice.

By the same standards you could declare lots of technologies inapt. (For example fossil fuels are way worse with all the pollution, oil spills, coal mine disasters, etc.)
Yes, o/c. Some of those technologies are also "outdated", but I don´t think that a coal mine disaster would ever threaten that large number of people as Chernobyl did or like Fukushima does, though on a smaller intensity level, but on a larger zone of influence. And all this was avoidable (o/c, not the earthquake or the tsunami as such, which were obviously not man-made).

Also could you please propose a cleaner, less dangerous technology that is readily available and can produce the needed amount of electricity?
There ARE zero emission technologies available, some of them since decades. The fact, that they aren´t able to "produce the needed amount of electricity" today, is a fake, insofar that those technologies have been hampered by political and economical "decisions". Yet, they exist.

In the short to mid term it can only be substituted with coal and gas firing plants and the like. Which is a lot worse. I don't really understand all the greens in Germany who'd like to shut down nuclear plants at once. What would you do afterwards?
Nobody wants to shut down all "nuclear plants at once". The real problem is that after a standstill in upgrading nuclear technology after Chernobyl, there´s increasingly planning for a "revival" of nuclear technology in many countries. W/r to investments into renewable energy this is clearly a bad thing.
Talking about Germany, it´s obvious that in this country there exists a vivid discussion about the use of nuclear energy since the 1970s. This is quite different from France, where there´s no such discussion, simply because the use of nuclear energy is linked in some intimate way with the French self-conception as a (military) nuclear power. The downside of such a position is concealment of the problems with that technology, as has been seen during the Chernobyl disaster, where the radioactive fallout stopped right at the French border.
Meanwhile, in Germany there´s an increasing surplus of electric energy (because of the increasing proportion of renewable energy), so that approximately 8 of the (older) nuclear plants would be dispensable. That´s where the "Atomic Consensus" of 2000 came into play. Now, with the conservatives cancelling that "exit" from nuclear energy on behalf of the big energy providers, the discussions are starting anew, o/c.
In such a political situation, it should be obvious that the nuclear disaster in Fukushima is an important incident. And in contradiction to a previous speaker, this is not because of a specifically German "Angst" (fear), but the wide-spread position of refusal results from a thorough discussion and a gain in understanding since decades. Personally, I prefer this attitude over the French´s or British one.
For most people in Germany the situation is clear: w/o an "exit", the bigger problem of nuclear waste cannot be tackled seriously (13,000 tons of high and medium radioactive waste, at the time being). The decision for establishment of a central radioactive waste repository in the early 1970s has been invalidated by time, with its location at the former GDR border meanwhile more or less in the middle of the country, and the geological conditions more than questionable, with all the nasty experiments with the "Asse" provisional
waste repository. It´s obvious that a predominant part of the Germans are "sick" of nuclear energy with all the billions of Euros of extra cost and high prices for electric energy as well.
As discussed numerous times on this forum, there are indeed alternatives for nuclear energy. In principle there´s neither a need for usage of fossil fuel or fusion gimmicks in the foreseeable future, with such a tremendous amount of energy available on this planet.
And don´t tell me about cost. With so many billions/trillions burned in failed banks, expenditures for a new energy production scheme would be just peanuts, and profitable!
