Britain Oxford a laboratory fusion power breakthrough, which will be applied to what? Here we are to address this issue for some discussion, I hope that these contents can help the need for friends.
Mention of "nuclear" has always been a colorful, and even some people are "talking about nuclear fear", feeling that nuclear power generation is a very dangerous power source. But in fact, the atomic nucleus stores a large kinetic energy, once the development and design of good utilization, can be used for hundreds of millions of light years of human application.
Today's traditional petrochemical power energy, has been close to the scarcity of controllable nuclear fusion, is considered to be the last way to deal with the energy problem. So why is nuclear fusion the ultimate power source? What other industries can it be used in? With this doubt, into the following theme style, "nuclear fusion".
What does it mean by nuclear fusion? Many people do not have a very good understanding of nuclear fusion, here circle a valid "nuclear fusion", also known as nuclear combination, fusion reflection, fusion reaction or thermonuclear reaction. Simply put, it is a kind of atomic nucleus into another kind of atomic nucleus, along with the release of kinetic energy, this whole process is nuclear fusion. Fusion energy is two relatively light nuclei, fusion into a heavy nucleus when the kinetic energy released, the key raw material for fission is the isotope of hydrogen, that is, "deuterium and tritium".
For example, the sun glows and heats, which is the basic principle of nuclear fusion. Many people understand that the sun's temperature is very high, the sun continues to collect and hair hot, when accumulated to a certain point will make the sun chemicals caused by nuclear fusion, which causes high temperature, and to the surrounding radiation source kinetic energy chemicals. When four hydrogen atoms get very close together at high temperatures and collide, they combine to form helium-4, the nucleus of an atom with two antiprotons and two neutrons, and release a great deal of kinetic energy in the process. The sun is a huge nuclear reaction device, radiating source kinetic energy outward for billions of years.
Instead of the opposite is the "nuclear reaction". Nuclear power plant is the use of the principle of nuclear fission to generate electricity, nuclear power is the core of the atomic furnace, atomic nuclei and the composition of the electrons outside the nucleus, the atomic nucleus consists of antiprotons and neutrons, when the nucleus of uranium 235 suffered from the outside world of neutrons of the negative electrons.
An atomic nucleus will digest and absorb a neutron, disintegrate into 2 relatively small quality nuclei, with the release of 2-3 neutrons, this constantly carried out, the establishment of the fission reaction type, which in turn causes a lot of thermal engineering, for this reason alternative to fossil fuel power generation.
Where do fusion materials come from? In fact, fusion materials are cheap and plentiful on Earth. For example, "tritium", there will be more than 45 trillion tons in the sea, just from the surface of the sea refining out, can be used for hundreds of millions of light years. Another example, in recent years, each country is in the substantial development of design space resources, in the vast universe, just a moon, there are a lot of helium-3, which is also the world countries flocked to capture the space resources for the sake. Thus, in the future, nuclear fusion may also give greater kinetic energy to mankind.
Why is nuclear fusion the ultimate power source? Nuclear fusion has the advantages of resource superiority, security, cleanup, high efficiency, etc., and it can reach the various stipulations of mankind for the future, idealizing the final power source. Imagine that every liter of fission in the sea can cause the equivalent of 300 liters of automobile gasoline. A one megawatt fusion thermal power plant would only require 600 liters of feedstock per year. A thermal power plant of the same scope is about to consume 2.1 million tons of coal per year. More to the point, on the Moon, Mars, Saturn, many stars in cosmic space.
There is enough helium-3 to allow humans to indulge for billions, or even billions of years, at that time, human beings do not have to worry about worrying about the lack of power energy, and therefore many biologists have shown that "nuclear fusion can become once and for all, to deal with the entire human energy crisis, the ultimate power energy". Can nuclear fusion be used in other industries besides power generation? At this stage, the most mature and stable use of nuclear fusion technology is the "thermobaric bomb", which is often referred to as a nuclear bomb, is the use of the kinetic energy of the atomic bomb explosion, the ignition of hydrogen isotopes, deuterium and other hydrogen nuclei of the fusion reaction.
The explosion is very lethal, the explosion occurred a moment, a city can be instantly destroyed. The second is the power generation, many of our countries, including in our country are in proactive scientific research, friendship fusion technology, used for human inhibition of nuclear fusion, so that it is used for power generation.
The current result is that the tokamak equipment can be utilized to complete more than 20-50 million degrees of synthetic sun. Not long ago in China's independent research and development of the "synthetic sun" announced the completion and success, which means that China in the manipulation of nuclear fusion technology, has made significant progress. At the same time, it also confirms that China has long been at the forefront of the world in the design, construction and operation of large and medium-sized tokamak equipment. In addition, at this stage, the nuclear reaction has not been used in more general industry.
Why nuclear fusion can not be widely used? The fundamental reason is that until now human beings have not been able to completely "manipulate" it, nuclear fusion nuclear energy, in addition to being used as a weapon of war, a large number of human beings are friendly use, such as the construction of nuclear power, power generation, etc., but the use of nuclear fusion, and not so very easy. Up to this stage, mankind has long been able to maintain uncontrollable nuclear fusion, but in order to rationally utilize nuclear fusion, it is necessary to be able to "manipulate" the efficiency of nuclear fusion and the scale of the operation, to complete the continuous, stable power export.
At this point, mankind in the grasp of fission nuclear energy city road, also has a long way to go. Thus fusion, despite its simplicity, cheapness, and environmental cleanup, is the more advanced, most durable source of power.
