Search for the root causes of nuclear disasters in six landmark nuclear accidents in history

Recently, Chang 'an Street Reading Club and Guangdong People's Publishing House jointly held the "Exploring the Future of Nuclear Energy in the Fukushima Crisis - Atom and Ashes" new book sharing meeting. Professor Zhou Tao, Vice Chairman of the China Nuclear Industry Education Society, Director of the Department of Nuclear Science and Technology of Southeast University, doctoral supervisor, full-time director of China General Nuclear Power Group, adjunct professor of Southern University of Science and Technology and Xiamen University, Professor Yin Xiong, researcher level senior engineer and Doctor, led the book. Two experts in the field of nuclear energy research and nuclear energy industry, through video link, from both academic and industrial aspects, on whether nuclear power plants are safe, why nuclear leakage accidents occur, what impact on our lives, China's nuclear technology development and other issues of common concern to the public, bring authoritative and detailed interpretation. Professor Yin Xiong believes that it is necessary to define the concept first, conventional nuclear power plants discharge nuclear wastewater, is treated and harmless to the environment, and the nuclear sewage discharged by Japan contains a large number of radioactive substances, which will cause great harm to the environment. The two concepts should not be confused, let alone questioned about the safety of nuclear power plants. He believes that the Japanese government has violated the three basic ethics of responsibility, technology and fraternity in this incident, which has had a psychological impact on the people of the Pacific coast region and caused great harm to the global environment and Marine life. The Chinese government is a responsible government. On the one hand, it will continue to exert pressure on the Japanese government, including politically, economically and diplomatically, to urge the Japanese government to comply with the call of the people of the world and stop the discharge of the remaining nuclear sewage. On the other hand, the relevant functional departments and enterprises of the Chinese government will strictly test the water quality, Marine life and seafood in the relevant waters, especially the Marine food that may be placed on the tables of the Chinese people, and will take corresponding measures even if there is a small problem. At the same time, he reminded the general public that buying iodized salt will not help prevent nuclear contamination and damage. Medical iodine tablets in nuclear power plants will only be used in the event of major radioactive material leakage accidents, and there is no need for ordinary people to take them. Regarding the safety of nuclear power plants, Professor Zhou Tao believes that the reason why nuclear power plant accidents are concerned by the public is related to the low risk rate and high risk characteristics of nuclear power itself. In fact, for more than 400 reactors in operation in the world, major nuclear accidents have only been in the single digit for decades, and the probability is not high, and the fatality rate of nuclear accidents is far less than traffic accidents. Or the energy industry other than nuclear power. However, the safety of nuclear power technology itself is sufficiently guaranteed, he took the Three Mile Island nuclear accident in the United States as an example, and the research results after many years showed that the cancer prevalence of local people did not increase after the smoking factor, which can be seen that its safety. The pressurized water reactor used in the Three Mile Island nuclear power plant is completely consistent with the technical route adopted by China. Most of China's current reactors are pressurized water reactors, which are designed with containment vessels and are safe enough to ensure safety. Nuclear safety is an important part of national security and people's security. As a person in the nuclear energy industry, it is still a long way to go to popularize the development of nuclear energy to the public. With public support and people's understanding, nuclear power can move forward better, faster and healthier. Nuclear power governance, nuclear safety governance, is an important part of the modernization, to ensure that nuclear power is foolproof, to eliminate the public because of the nuclear power technology is not familiar with the doubts, and then increase social support for nuclear power recognition, to create a good atmosphere for nuclear power. In the double background of energy crisis and environmental crisis, nuclear energy is a very good alternative energy, but the danger of nuclear radiation is self-evident, as Professor Proloki, the author of the book "Atom and Ashes", said: "When it is safe, nuclear energy is the cleanmost energy in the world; In the event of an accident, nuclear power is the dirtiest energy source in the world." So how do we deal with this contradiction when it comes to developing nuclear energy? How to develop nuclear power more safely? Professor Yin pointed out that nuclear power is comparable to other forms of new energy, including solar and wind, in terms of environmental benefits. As the known energy source with the highest energy density, it is also a low-carbon energy source, which is irreplaceable in strategy. The technology maturity of nuclear power, economy and general safety have been verified in the history of nuclear power development, large-scale use of atomic energy technology is completely feasible. Although nuclear radiation is a threat, mankind has mastered the basic methods to avoid this threat. Professor Zhou then introduced that China has made great progress in the research and development, application and autonomy of new reactors: reactor technology is gradually realizing the leap from the second generation to the third generation, research on nuclear fusion is also increasing, and private capital has also appeared in the nuclear energy field, and the entire industry is full of vitality. The two experts finally discussed the six nuclear accidents described in the book "Atoms and Ashes", and agreed that although several major nuclear accidents in human history have environmental factors, the most critical factor is the human factor, which is not mature technology, management defects, government supervision is lacking, and the safety awareness of practitioners is indifferent. In the context of the general environment, there are also reckless and reckless behaviors that ignore safety facilities and safety management for performance, and these problems are generally due to the lack of nuclear safety culture. Fortunately, these devastating nuclear accidents have also encouraged us to think about and improve nuclear safety measures, improve safety standards and enhance safety awareness, and there is every possibility that the nuclear industry can prevent problems before they occur.

The meta-problem of the meta-universe: Mapping Critical reflection

Since the concept of "meta-universe" "landed" in the Chinese thought circle in 2021, it has become a new opportunity to trigger theoretical thinking. A variety of cutting-edge questions have been asked about this "event," focusing on the trendy terms and abbreviations repeatedly used in tech hardware; On the other hand, many questions focus on humanistic reflection and future assumptions, which are connected with metaphysics or ontology, ethics, philosophy of science and technology, law, political science, aesthetics, art, etc., and the investigation has two tendencies of optimism and pessimism. The urge to ask questions is natural, but there is also a lot of suspicion. On the first, much of the discourse is simply about rephrasing established things; The second, and much more involved, is the unstandardized "possible" question of scientific fact, to which one has all the answers, even if the answers are contradictory. We focus on the latter kind of problems because they are better reflected in the mental boundaries presented by imagining future prospects. Our approach is to attempt a philosophical "meta-question" mapping of these questions. In other words, it is to re-examine and evaluate the "ways or attitudes" in which the humanities and social sciences have raised various possible questions over the past year or so; At the ideological level, what theoretical structure leads them to believe that "a problem exists (or does not exist)" in the meta-universe phenomenon. The "drawing" method is a kind of "ideological geography" treatment, that is, the "problems" of different positions and field backgrounds have different "conceptual geography", which contains the plural "meta-problems" of different distribution. The reason why it is necessary to draw such an original problem is that the meta-universe is the "place to go" that has yet to be drawn. It has the potential to give us exactly what it has not yet given us, and that is why it is possible. Based on the various "meta-questions", we can see which are true questions and which are merely repetitions and branches of the original question. This paper attempts to start from five perspectives, which relate to five positions on the meta-universe, respectively, from the typical propositions put forward by some scholars in the past year or so: first, the converging free world of extended mediaism and its conception; Second, the fractured imagination based on postmodern difference theory; Third, the equal demand and capital criticism of the meta-universe; Fourth, the ultimate significance of the meta-universe to human beings from the perspective of existence; Fifth, the fantasy of the new person based on the virtualization of the body. In each case, we will generalize with one or more "meta-problems" that contain contradictions, thereby revealing the limits of how the mind can deal with the phenomena of the meta-universe. For such a new concept of the meta-universe, this may also be a new way to summarize and evaluate. The same Utopia: extension and suppression Since the space of the meta-universe is virtual, and information resides in matter and transmits the meaning understood by the mind, it is natural that the meta-universe should be equated with the information medium. This is why many communication scholars pay special attention to it, and their position can be named "extended mediaism". This theory is based on McLuhan's classic definition: the medium is an extension of man. They are trying to make the medium universal, to accommodate (and even replace, replace, and reconstruct) the entire real world, and the meta-universe is exactly what they need for this infinite medium. Their argument can be summarized as follows: First, media is the expression of human social relations, even the relationship itself; If relationships reach infinity, the medium is everywhere; Since the meta-universe is a cosmic medium, it (necessarily or possibly) gives the medium the greatest extension. Second, when this extension reaches infinity, since the connection between the medium and human thought and activity is at its strongest, then the meta-universe becomes an indispensable infinite medium for contact with reality; Because reality and the media are so closely related, reality itself is the only omnipresent medium. For example, some scholars confidently predicted the media vision represented by the meta-universe: "The future media will no longer be (or mainly not) a series of fixed 'entities', the new media form is a' network 'woven and weighted by algorithms, is a complex system", is "the highest form of' human relationship connection 'in the real world". So the future will be the "era of context," the era of "always on," where "almost everything you do offline is done online." Here the "intermediation" of the media itself is emphasized, although all the affairs are handled online, the difference between it and the offline is still obvious. However, he also argued that the iteration of media will evolve into an era of "everything is media", and media will shift from "a tool for conveying information" to "a link of relationships", even a cup of coffee is a medium for conveying information. Leaving aside the fact that coffee seems to convey information without the iteration of a medium, here he seems to extend the medium to all actual beings as long as they can serve as a contact medium for social relations. However, the contradiction lies in the fact that the medium is only the carrier and "online" system of the information of the existence (the existence), why has it become the existence itself? The answer seems to lie in the metaverse itself, which as an information medium or "open source platform" has been extended into the "form" of the universe itself, the objectified data model. In a sense, this is a modern "algorithmic" version of ancient Platonism. In the meta-universe, "the virtual and the real are highly interoperable." The meta-universe "through the upgrading of immersion, participation, sustainability and other characteristics", with the help of "many independent tools, platforms, infrastructure, and collaborative agreements between various subjects", the boundary between virtual and real is completely eliminated, and unified into an infinite, organic "ecological level complex system".

I've been having a lot on my mind lately

A few days ago, I had a strange dream, dreaming of participating in an activity, I saw the beginning of the activity far away, and then ran in that direction, and the result was suddenly seized by someone hard to the leg, can not walk. So he asked the guy, and the guy said, "Why did you run?" I answered the activity began, want to participate in the run ah! The man said he didn't see it! I said, don't you see you should be fixing your own eyes, not grabbing someone else's legs!Then, after a day to deal with things outside, was rogue cut in line, loudly questioned, rogue is ignored, a dead pig is not afraid of boiling water hot look, their own low quality country scold, also no effect!The next day, the greedy neighbor violated the interests, a big quarrel!And then deal with the lazy property, in order to repair a little cement, continue to negotiate, the property is still the same, the old tone: manpower shortage, have to queue, if you are in a hurry, you have to do it yourself, and so on… Really speechless, also do not want to wait, went to the next decoration of a family asked, all at once to solve, half a bucket of cement, and mud board, mud board, do it yourself, half an hour all done. Of course, also to the decoration of the master thanks!I wonder if any of this has anything to do with that weird dream?A good man is bullied, a good horse is ridden.Sometimes, can not blindly kind ah!Against the wicked, rogue, more complex, greedy, more able to protect their own interests ah!

As a child, the sound of firecrackers can drive away the bad luck of the year

In my memory, there is no bad radish, stewed vegetables, and I feel that there is no taste of the New Year. There is no long several hanging whip, ear-shaking double cannon, and I feel that there is no New Year's weather, my father often said, "the sound of guns can drive away the bad luck of the year." On New Year's Eve that year, my mother prepared lunch: stewed vegetables and stir-fried radishes. Radish is bad, boiled meat soup, pour water fried radish slices, soak for a few days, radish will enter the meat flavor, which is what I said "New Year"; Stewed vegetables, cooked pork belly, cut into millimeter thick slices, hot pan fried rich fat, and cabbage, vermicelli stewed together, with boiled pork belly, cabbage and vermicelli are also into the "New Year flavor". It was a must-have for Chinese New Year when I was a kid. Mother cut the meat and said that father was not back. After days of heavy snow, the gray and black village was wrapped in a thick quilt, and the road leading from the village could only be discerned by the footprints and ruts of sparse Lala. Father went to the town early in the morning, and the town was not far away, let alone by bike. The mother wanted to go out to see, but suddenly, hearing the clanging bolt, she put down her knife and meat, went from the kitchen to the living room, pushed open the cotton curtain hanging in front of the house, and then a stream of hot air rushed out of the door, only to be forced back by the cold inside the courtyard, and the white fog formed during the struggle spread everywhere. It was my father who came back and saw him push the car to open the gate, the entrance was not far, and parked the car near the wall on the inside of the gate, and the big red bag hanging on the handlebars swayed back and forth. Mother hurriedly let go of the curtain, stepped through the "squeaky" snow in the yard, and came forward to untie the big red bag that shook. (If you like it, you can follow wechat public account shanhelulu.) It turned out that my father had gone to the market town to buy fish, and remembered on the way back that he had forgotten to pay, so he hurried back again, and there was a delay in the round trip. While speaking, my father had entered the room with my mother, and I secretly laughed at my father's immorality in my heart. The living room, directly opposite the door, attached to the back wall is a yellow face and black edge of the paint table, with a long time, the color has become dim. In the middle of the table is placed a gray black double hook ear incense burner, after the incense burner a purple paper pasted on the back wall, writing the name of recent generations of ancestors, line by line is the blood handed down from generation to generation. After lunch, the sky gradually dark down, mother began to make dumplings, father will prepare incense. Night hung down, hot dumplings out of the pot, according to the rules, the first bowl to worship ancestors, I took the bowl of chopsticks put behind the incense burner. Father cleaned up the old ashes in the furnace, lit incense, and inserted them in turn. My father used to say, "Incense is a messenger to the other world, a reminder of our ancestors." On the floor of the table, my father lit a paper fire, and the flashing fire jumped up enthusiastically, a warm rush to my chest, I looked at the smoke slowly rising, gradually, my mind emerged when my grandfather took me to the south of the village to play. It's time for the cannon. The father went to the middle of the courtyard, holding the cannon in his left hand and lighting the shinanzi with his right hand. Hearing the sound of "Bessie", I took a few steps to hide under the eaves. Looking at his father from a distance straightened his left arm, and in a flash, the cannon flew out of his father's hand, and with a bang, the flash of fire in the air illuminated the whole courtyard, and also illuminated his father. Father was of medium height, but so tall in the firelight. The night was already deep, and the family sat around the charcoal fire in the kitchen, listening to grandma tell them about their eventful years. The snow in the yard set off the light from the Windows and glistened on the huge bug tree in front of the house.

Where eyes and feet cannot reach, words can

I feel that I have not read for a long time, the kind of happiness that is full of books in the afternoon sun, holding my carefully selected books, has been lost for a long time.Often listen to, reading is the lowest cost of cultivating their own vision and pattern of the way, it is not.Life is too short, so short that we can only experience a limited magnificent or as plain as we can see.In the book, you can feel different situations and life experiences.After a certain page turn, a certain line just hit itself, "Ah, I think the same as the author."Even if the author and never face, even if the plot and characters in the book are fictional, touching and feeling are always there.In the experience of others to know and reflect on their own at the same time, but also may be able to get a friend, a reminder,A mentor who can offer another way of looking at things. Why did you suddenly think of reading,Probably because I recently followed up the study progress of my newly enrolled junior teacher,When you suddenly find that you have to teach your little brother from scratch, you don't know where to start.Because I don't know what my little brother might know and what he might not know.Advance communication is really needed.However, why can young tutors accurately prejudge the appropriate teaching plan?Then explain the explanation in simple and clear language that the younger brother can understand.It's a really powerful skill to be able to understand where someone is and how they need it,Improve each other's work efficiency.I guess this is because the rich teaching experience of primary and secondary school tutors is indispensable.I believe that the young mentor also remembers the feelings of each stage from his student days,Read a lot of books, professional and non-professional,Then switch your posture to the level of the object you need to communicate with.To think and understand the other person's situation from their point of view,Then the best solution is given.I have to sigh that reading more is really a necessary thing. On the basis of the previous' there is Yan Ruyu in the book, there is gold House in the book ',There should be. There's a better, gentler version of yourself in the book.Attached is also very gentle teacher Luo Xiang a paragraph, and you share encouragement.I also hope that I can also strive to become a gentle person.
