Recently, by our own research and development of the International Thermonuclear core parts manufacturing in the world the first through the certification authority, which is a great contribution to the International Thermonuclear project in china.
Above is our scientific researchers through 12 years of successful development of new materials. Soon, it will be sent to Europe to participate in the International Thermonuclear Experimental Reactor project. This project also has a more image name: "artificial sun". And this material will constitute the most core of the artificial sun structure.
Program of the International Thermonuclear Experimental Reactor, English referred to as ITER, is currently the world's largest and most influential international research cooperation project. The goal is to achieve a controlled fusion reaction, plans in 2019 to build an experimental reactor in france. The principle and mechanism of the thermonuclear experimental reactor to produce energy light and heat is similar, and therefore have a "artificial sun" reputation, and to build up the core of "artificial sun", which requires special materials to build a "firewall" to resist the high temperature environment inside the device on million degrees.
In the International Thermonuclear Experimental Reactor project, there are a number of countries in the development of high temperature materials such as the core, Chinese scientist undertakes the development of this material in the reactor, the core position, directly facing the high temperature fusion material, which was to become the first wall of the reactor "". ITER's design requires that the first wall withstand 4.7 megawatts per square meter of heat, which can instantly melt a kilogram of steel.
The reactor and Materials Laboratory of Southwest Institute of physics, nuclear fusion industry director Chen Jiming: experts in ITER, my heart is not the end, the end can not be able to endure the 4.7 MW per square meter. Through our self-developed components, we became the world's first through high heat load test certification, we can also say the first to get a production license. So it's a big contribution for ITER.
Duan Xuru, vice president of Southwest Institute of Physics: the first wall is a core component of the ITER, the Chinese master of these technologies, in the future we are building their own (thermonuclear fusion reactor), has a great role in promoting.
Nuclear fusion: hope for future human energy problems
Nuclear fusion is an important form of nuclear energy, some people even said that if mastered the nuclear fusion technology, human beings no longer need to compete for energy and war, the development of mankind has a profound impact. So what kind of energy is this?
Nuclear energy is the energy released from the nucleus by nuclear reactions, at present, our common nuclear power plant, is the use of such energy. However, the current nuclear power plant is mainly to split the heavier atoms into lighter atoms and release energy, this process is nuclear fission. Nuclear fusion at the research stage is just the opposite.
Nuclear Industry Southwest Institute of physics vice president Duan Xuru: nuclear fusion is a lighter element atoms together to generate heavier elements of the atom, it also to release energy.
In fact, such a nuclear reaction is not far away from us, the sun shines on the earth every day, its light and heat from its own internal slow and lasting nuclear fusion. Therefore, to achieve stable nuclear fusion under artificial control facilities, it is naturally become "artificial sun". Compared with ordinary energy, the advantages of nuclear fusion obvious, first of all, the source of fuel is very rich.
Nuclear Industry Southwest Institute of physics vice president Duan Xuru: nuclear fusion energy is mainly hydrogen isotopes, deuterium and tritium violent reaction. The deuterium inside a liter of water, if it is all fused, produces the same energy as burning three hundred liters of gasoline. On the other hand, its environmental acceptability is better, because the fusion reaction, the product is produced helium, helium itself does not have radioactivity.
Huge energy and safety and environmental protection, nuclear fusion has long been regarded as the hope of solving future energy problems. As early as 1952, humans achieved artificial nuclear fusion, but the use of such a way.
Enormous energy is from hydrogen fusion reaction of nuclear material dramatically, but this moment release can be devastating effect, how to make this kind of energy is slowly released in an orderly manner under the control of the people, this is the first hydrogen bomb explosion in the 64 years after the mankind has been trying to tackle the problem.
Nuclear Industry Southwest Institute of physics vice president Duan Xuru: in the course of the study found that there are many challenges have not solved, rely on the strength of a country to conquer, and now there is difficulty.
For this reason, in 1985, the international initiative began multinational cooperation in the development of controlled nuclear fusion reactor, which is the subsequent ITER project. In 2006, 7 countries and regions including China, the signing of the agreement, the International Thermonuclear Experimental Reactor project was officially launched, which is China's participation in the largest international scientific cooperation project. Experts said that with the advance of ITER projects and autonomous nuclear fusion projects, the human race is expected in the next 50 years, so that this huge energy and clean and safe energy into millions of households.
Chinese wisdom allows new materials to withstand the sun high temperature
Our country began to formally participate in the International Thermonuclear Experimental Reactor project from 2006, in which China has 10% tasks, and certified through the reactor core material, can be said to be one of the most difficult technical breakthrough
