        Bet those paper suits helped!?! 🤥🤫 privatize the profits, socialize the losses. 🤢🤮🤑at the expense of all life on earth. Killed an entire ocean. Pretty big part of the ecosystem. We are so fucked.

          This spill killed nuclear power worldwide. Everyone expects Russians to blow stuff up, but when the Japanese can't control it that gets people's attention.

            they built them too close to the water and not on an elevated area

                Nuclear energy should NOT be a thing. It's madness

                    This report s tad old and doesn't mention TEPCO's "frozen soil barrier" to contain polluted-by-radioactive-substances ground water. In a nightmare scenario, a somewhat-less-than-major earthquake knocks the freezing unit offline. If the "frozen soil barrier" defrosts, all that radioactive ground water will be released into the Pacific ocean. Plastic particle pollution will then be much less of a problem/concern for Pacific ocean islands and nations as the milliseverts climb the food chain.

                      It is a rarity that someone(/s) of incredible intelligence can explain an intricate concept in a manner so easily understood - even by someone as blunt as I am!

                        Understanding a nuclear powerplant accident. Fukashima. Japan should have never been allowed to have nuclear energy, it is on a volcanic unstable seismic zone. The competitive advantage of nuclear energy gave cheap electricity to produce the products and cars we bought all over the world. This should never be allowed!!!!! Japan should have had an economy based on the resources at its disposal. A political decision has poisoned the world. Radioactive water is still entering the ocean!!

                          many of the people who worked on the site after the incident were immigrants who are treated at second class citizens and couldn't find decent jobs

                              For the sake of insanity shut down these damn monsters it may already be too late. Nuclear morons .robots cleaning up corium 2grams hurray only 50,000 tons to go. We are really really stupid humanity doesn’t deserve to survive. We don’t have the right to fuck up this planet and why why why would you want to?

                                Moral of the story... if you are going to build nuclear power plants along the coast of Japan, do more to protect the backup power generators. In other words, prepare for the worst case scenerio (which the engineers obviously didn't do).

                                    I love how instead of diverting all available funds to this containment , the Japanese govt instead is hosting the olympics and spending how many millions on an olympic village and stadiums that will be left for nothing after the 2 week event lol GREAT JOB!

                                      Not one person died as a result of the Fukushima Daiichi accident. Not. One.

                                      In fact many thousands of elderly seniors died in the hasty evacuation from Fukushima Prefecture (heart attacks, falls, etc). The WHO has since acknowledged that the people evacuated would have been better off staying put.

                                      Everyone looked to Chernobyl in what would happen but the reality was that Japan is a far more well organised and run country than the USSR ever was and was able to properly manage and contain the accident. Radiation levels in the surround areas have returned to normal levels and people are beginning to slowly return home.

                                      Nuclear energy actually emerged stronger than ever in terms of robustness and safety but unfortunately the crazy anti everything ludite zealots sought to use Fukushima for their own evil and selfish ends.

                                      Bottom line: if we want to combat climate change and reduce harmful CO2 emissions we MUST go with nuclear energy. When you look at deaths from nuclear vs deaths from coal/oil/gas the answer is obvious.

                                            All that really needs to be understood is that mankind was never ready for this technology and their failures prove it.

                                              if only we had been using fluid fuel reactors none this would of happened cant have a melt down when your fuel is already molten and is your cooling fluid also no release of radio active elements since they are all locked up in the fuel salt thats solid at room temp
                                              solid fuel reactors are just silly you cant burn up more then 1% of the fuel and if you your cooling is lost the clading reacts with water even Alvin Weinberg the father of nuclear power wanted to move to fluid fuel

                                                @12:13, you see bubbles in the Reactor Pool, why are they there? The video doesnt give a date though.
                                                EDIT: Saw the film date at the end, Feb 2012. So I guess cooling maybe?

                                                      Japan has very bad luck with nuclear, first Hiroshima now fukushima, they should make this country free from this material obviously it's not good for you. Also they are dumb people with no backbone I expected much more from Japanese people. You poison water.

                                                          In retrospect, building a nuclear power plant next to the ocean and on an active faultline was maybe not the best idea?

                                                                To contain the molten radioactive fuel, why is there not a structure underneath that would divide the material into separate compartments to control the chain reaction? There is probably a reason why this hasn't been used but I cant think of one.

Is it not the movement of the ENTIRE CONTINENTAL PLATE that stretches for thousands and thousands of miles that causes the earthquake??? Why/how in the hell is there 1 single point that can be considered the center of the earthquake.

When things malfunction, the fuel and coolant simply drain into a big static tank. The shape of the tank makes things sub-critical and the heat generation is reduced. The drain tank is designed to lose heat much more quickly than the reactor core. In short it's simpler, safer, cheaper and coming soon. Oak Ridge in USA had working plant in the 60s. That project should not have been shut down.

                                                                                      Is a shame that we had to notice the heroic work of the workers that "save the day" in an emergency situations only. Work on a place like this is a continuous state of emergency. Not only nature hazards as an earthquake are in the mind of the designers an engineers, something so simple as a wrong understanding of the operational protocols could generate an accident. Afterwards this terrible accident the more easy thing to do is criticizing the many faults that were exposed, instead of focusing in the saddly lessons that we can extract from it😢🙏❤
