Now the hottest thing on the Internet is Japan's discharge of nuclear sewage into the Pacific Ocean, think about them are really bold, risking the world, the Internet is a crusade, there is no shortage of me this one. According to what I learned and understood, it has become very difficult to talk about this impossible task, to use a scientific attitude to understand the specific situation, but it is easy to criticize them, thinking of the British anti-science action of burning 5G antennas, and there is the problem of exaggerating the radiation of the base station, if it is not well studied, it will have a bad impact on the construction of our own nuclear power plants in the future. Maybe we think too much, let's take a look at how to write better, and it will not anger those indignant patriots.
First of all, how did this batch of nuclear sewage come from, exactly ten years ago, there was a 9.0 magnitude earthquake in northern Japan, and a tsunami of tens of meters high hit the Fukushima nuclear power plant, when six units inside were shut down normally, but the nuclear fuel rods could not be stopped completely to stop the decay reaction, that is, each reactor still maintained a heat of hundreds of kilowatts. If this heat is not treated, the reactor core will melt, and it is conceivable that the catastrophe is like the flow of lava from a volcanic eruption, and radioactive materials will flow everywhere, melting through all the materials!!! Don't even think about it, it must be cooled with water, and the fastest and most convenient thing at that time was to use seawater.
The problem is Japan's TEPCO, they are responsible for the operation and maintenance of nuclear power plants, large companies should be very experienced according to the reason, but it is the ghost that makes the gods delay the time, and 4 units have serious core melting accidents. The steel shell of some of the reactor was melted through, causing a steam explosion, and more than 300 square kilometers around it were contaminated with excessive nuclear radiation. At that time, there were reports, and the video was also played continuously, which made people look heart-wrenching and anxious, and many people were killed or injured. TEPCO must continuously inject a large amount of seawater into the scrapped core to cool, and because this seawater is in direct contact with the reactor, the seawater that is channeled is also the most radioactive liquid in the world.
In addition, groundwater is also constantly infiltrating into nuclear power plants, and more and more polluted water cannot be stopped, and it is necessary to increase by more than 100 tons every day, which is a big trouble. Under normal circumstances, highly radioactive waste also produces more than 30 tons a year, and there is no problem with the original storage facilities of the nuclear power plant, but now it has suddenly increased by more than three thousand times. The Fukushima nuclear power plant is currently filled with more than a thousand large tanks, totaling more than 1.3 million tons, and the old tanks are still overwhelmed and begin to leak. I am not an expert and do not come up with ideas here, I heard that there are many ways to solve it, we officially said that they did not exhaust various programs, the nuclear pollution wastewater into cement buried deep underground, think about it to know that this cement block has no use for anything, but also quite expensive. There are also holes several kilometers deep, discharged into the deep underground, or the electrolytic discharge of wastewater into the atmosphere, which is highly costly and strongly opposed by the local people. Think about it, think clearly tomorrow and then write.
