The level 7 is due to nuclear leaks in several of his locations, with only one power plant in Chernobyl. But Chernobyl is the most influential.

From the perspective of the impact of the Fukushima Daiichi nuclear accident and Chernobyl, the impact on the off-site from the gaseous route alone will not be more serious than the radioactive impact of Chernobyl. However, since Fukushima is a coastal site, the impact on the public and the environment through the liquid route is uncertain, and the environmental impact of the liquid route of radioactivity will certainly exceed that of Chernobyl. The current political impact of the Fukushima nuclear crisis should be far greater than the impact of the Chernobyl nuclear accident, and the environmental and public health impacts of the Fukushima nuclear leak in general must be very, very limited.

As far as Japan's disaster relief performance is concerned, it is probably too optimistic to set it at level 7. After all, it's only been a month, and the success of the disaster relief is really far away.

But the fact is that it is level 5, and it would be foolish to deceive the international lie about level 7 and it will be detected by international nuclear safety.

In terms of radioactive emissions, INES defines a Level 7 event as "an environmental release event that results in an environmental release corresponding to a radioactive amount equivalent to the release into the atmosphere of more than 1016 Beccos of iodine-131". According to Japan's estimates provided to the International Atomic Energy Agency, the total amount of iodine-131 emitted from the Fukushima nuclear accident was Beckel, which met the criteria for grading a Category 7 event, but the total amount of iodine-131 emitted from the Chernobyl nuclear accident was Beckel, a difference of 10 times.
From the perspective of emission mode, the Chernobyl nuclear accident is the first emission of one nuclear power unit in a low-power critical state, which is a short-term elevated emission mode; The Fukushima nuclear accident was caused by the release of part of the nuclear fuel of the three nuclear power units through the damaged pressure boundary after melting, and the release of some radioactive materials by the other units due to the lower water level of the spent fuel pool. For a month, the Fukushima nuclear power plant has continued to release radioactive materials into the environment, but the emission location is low and the atmospheric dispersal rate is slow.
However, the Fukushima nuclear power plant has more than 10 times more nuclear capacity than the Chernobyl nuclear power plant, and some of the polluted water is discharged into the sea, and its long-term impact cannot be ignored, and should be closely followed and concerned.
If radiation leakage continues, it will have an impact on the sky, the atmosphere, the environment, and the ozone layer, and the radiation level will exceed level 7.
From a development point of view, I think it is necessary to raise the safety level, and perhaps the International Atomic Energy Commission may reclassify the maximum level of nuclear accidents to 1-10.

There is a large amount of nuclear contamination leaking out of the plant, causing huge health and environmental impacts. Inside the plant, the protective walls of the nuclear reactor were destroyed and could no longer be built.

Level 7 is just the current state, and it will develop in the future.
The beginning of the apocalypse is in Fukushima.

According to my estimates, the first time it was **, there was a core meltdown, at least a few dozen tons of fuel rods.
At the time of reactor No. 3, it was already foreseeable that the situation was likely to develop to the point it is today.
The Japanese are desperately trying to save money, the reactor itself has a major safety hazard, it is overdue for service, and the safety system is not fully functional.
After the accident, the goal of all efforts was not to suppress the development of the situation as soon as possible, but to do our best to save money by preserving equipment and nuclear fuel, so we made almost all the mistakes we could make and finally rushed to Chernobyl.
I've found that one of the great things of the Japanese is that they do small things big, bigger and bigger, more and more out of control. That's what it is"or"As soon as the Japanese or, things are going to be bad, this is not, there is news that TEPCO ** said that the Fukushima nuclear disaster "or surpasses Chernobyl".
I think people have to be stupid to make Fukushima Chernobyl, but the Japanese often test my imagination, so.
Stay inside? What's inside? There is no one inside the reactor, and they don't do anything serious now, mainly holding the radiometer and pretending; If the Japanese talk nonsense and do not make drafts, the situation is no longer what they say it is, and now their main job is to show it to the international community.
For example, he has been doing it for several days, saying that he is going to restore the power **, and plans to restart the cooling cycle or something, and if you think about it carefully, you will know how fooling people are. His four reactors are big **three, and there is one small ** twice, and the shells are blown up, do you think the pipelines of his cooling system, valves, pumps, distribution boards, control cabinets or something, these are still intact, is this possible? After the big ** to restore the cooling cycle, the workload is very large, the technical content is very high, and it is also very dangerous, even if there is no nuclear leakage, it is not a simple job, and it is far from the Japanese white potato that only has "50 dead soldiers" left to do well.
It takes a week to connect the cables, so what about entering the reactor building to repair and restore the cooling cycle? The amount of work and difficulty vary by tens or hundreds of times. Besides, the core has melted down, and the cooling system can be restored.
Clear-sighted people know that it is impossible, why should he do it? Shifting focus is the real goal.
As for how many years of recovery, I can only say that most of the radioactive nuclear waste has a half-life of 30-90 years, which means that you and I should not expect to see it in our lifetimes. Moreover, this half-life indicates that it will continue to release most of the radiant energy for decades to centuries. It is equivalent to lighting a lantern, and after a hundred years, the brightness drops to one-tenth or half, which just contributes most of the waste heat to the environment.

How bad the leak is at the Fukushima nuclear power plant in Japan: it depends on how far away it is, and the farther away it is, the less damage it will cause.

Recently, it was reported on television that Japan's nuclear power pollution would pollute the entire Pacific Ocean in 30 years. Creatures in the ocean will mutate, humans will die of leukemia and other diseases one after another, you can watch the Japanese TV series "Blood Suspicion", and modern scientists can only be amazed!
Because the nuclear fuel rods release a lot of heat when they are used, the water is constantly cooled repeatedly, but because the cooling system is destroyed, the heat generated by the fuel rods cannot be exported, and the water outside begins to evaporate, and when the water dries, it begins to melt the zirconium jacket (which wraps the fuel rods), so the leakage occurs
** occurred off the east coast of Honshu, Japan, with frequent strong earthquakes of continuous magnitude, magnitude and magnitude, power outages in Fukushima, Tokyo and other places, and tsunami warnings issued in some areas. A total of 4 people were killed and 97 injured in this time, including a fire warning issued at the Daiichi and II nuclear power plant in Fukushima, and it was found that there was no fire after verification. The Fukushima Daiichi and Daiichi Nuclear Power Plant is one of Japan's most important nuclear power plants, and if the nuclear power plant is damaged and leaks, it will not only endanger Japan's Shizhi Nuclear Plant, but also neighboring countries will also be threatened by nuclear contamination. >>>More
The expert is right, the fission is mainly caused by the U-235 substance, and the U-235 fuel for nuclear bombs is extremely rich in more than 95, while the fuel used in nuclear power plants is extremely rich in only 3. For example, if we use fire to light alcohol, it will burn, but if we use fire to light liquor, it will not ignite. >>>More
First of all, it should be noted that fission nuclear power plants are not clean, although they do not produce pollution when generating electricity, but the nuclear waste produced by nuclear reactions is difficult to dispose of, and the slightest carelessness will seriously harm the environment, and once an accident occurs, the consequences will be even worse (such as the Chernobyl accident), in view of the above reasons, some European countries (such as Germany) have implemented a nuclear abandonment policy, no longer build new nuclear power plants, and have closed many original nuclear power plants. >>>More
Whether it is a conventional thermal power station or a nuclear power plant, it is necessary to condense the exhaust steam after the steam turbine is driven to generate electricity, so a large amount of cooling water is required; Due to the high cost of nuclear power plants, in order to dilute the cost, the general unit capacity is very large, and because most of the nuclear power plants have low steam parameters, the heat released through the exhaust steam is much more than that of conventional power plants, therefore, in order to reduce the consequences of thermal pollution, many nuclear power plants are built in coastal areas. >>>More
