Abstract: the use of lead bismuth eutectic mixture (44%, 56%) as a nuclear reactor coolant, because of its physical, chemical and thermodynamic characteristics, these characteristics can be the most perfect to meet the safety requirements of the reactor. During the operation of nuclear power plant, there is no problem of corrosion of structure material in the loop, and there is no problem of the standard of 10-15.
In the recent International Conference on China nuclear energy, the international energy research and development and Reform Commission International Cooperation Center, said Wang Jin, director of the International Energy Research Institute, said: "Fukushima nuclear power industry development into a few years of winter, with the introduction of China's manufacturing 2025, nuclear power industry is in the development of spring." In this context, the metal bismuth as a nuclear power plant in the application of a wide range of metal raw materials, will usher in the peak consumption.
Nuclear power development ushered in the policy of spring
China district director of the world nuclear power industry, FrancoisMorin, the prospects for the development of the global nuclear power industry is full of confidence. He said that with the introduction of China's manufacturing 2025 this week, nuclear power will accelerate the pace of going out, China's goal is to achieve the transition from nuclear power to nuclear power power. In the future, the size of the world's nuclear and nuclear service purchases will reach $575000000000, of which, the aging of the reactor units to be dismantled in 2030, which will bring $92000000000 in business opportunities.
Xu Yuming, Deputy Secretary General of the China Nuclear Energy Industry Association, the use of data for the domestic nuclear power companies outlined an attractive blueprint. Introduction according to Xu Yuming, as of April this year, domestic transportation, in construction and proposed nuclear power plant a total of 52, which has been put into operation have 23 sets, the total installed capacity of 21.4GW, built 27 units, the total installed capacity 29GW, approved and 2 and Taiwan. "Within this year, there will be 6 to 4 units approved, there are 6 to 4 put into operation. By the end of this year, the total installed capacity of the national unit will reach 30GW, by then, China's nuclear power will scale in the world ranking fourth, the total number of nuclear power will exceed japan."
China inland nuclear power plant development
It is worth noting here, the world's 50% of the nuclear power plant for inland nuclear power plant, while China is distributed in coastal areas, inland nuclear power construction planning due to Japan's Fukushima nuclear power accident all suspended. From the commercial operation, AP1000 as the three generation of advanced technology, the world is still no business experience; Hualong 1 and CAP1400 as China's independent research and development of the three generation of technical representatives also lack of experience support.

He said: according to the nuclear power development plan, by 2020, China's nuclear power installed capacity of 35GW, an annual investment of 100000000000 new nuclear power, which equipment accounted for 50000000000. That is to say, the total investment in nuclear power will reach 5 in the next 500000000000 years!"

The core issue is the solution of public opinion and government support
Xu Yuming said, when the inland nuclear power construction, in fact, is not a technical problem, but the understanding of public opinion, support and determination of the government. Like France, more than half of nuclear power are built in the inland. Now China needs to nuclear power technology, security for a more in-depth science, the elimination of public concerns, in order to allow the government to make the ultimate risk and interests of balance and decision-making. "I personally believe that China's current technology, the construction of nuclear power projects in the inland security is very secure, I am very confident. Our nuclear power plants take a lot of safety measures, even in extreme cases, it will not affect the Yangtze waters."
Lead bismuth alloy is the best choice for nuclear reactor coolant
Xu Yuming talked about the nuclear safety issues mainly concerns the mere mention of the nuclear talks nuclear leakage and nuclear radiation. Russian scientists have been searching for a new nuclear fission method to replace the highly radioactive uranium in 1986 after an explosion at the Chernobyl nuclear power plant in Russia. In 2013, Russian scientists discovered that the mixture of lead and bismuth can be used as the main body of the mixture in a certain condition. The mixture can be used as a new nuclear energy. Russian researchers used lead and bismuth as raw materials, the use of lead bismuth in the use of a time limit for the use of the auxiliary equipment, it is impossible to make the explosion. Therefore, such reactors have the ability to resist terrorist activities. Experts pointed out that the use of lead and bismuth as raw material of nuclear power plant will be more secure.
Russian researchers is accelerated by using a cyclotron high-energy protons bombarding mixture of low melting point of lead and bismuth when new discoveries. Experiments show that 6 per unit of energy consumption per unit of energy output. Scientists explained that the atomic fission of lead and bismuth can be lower than uranium -235 1/4, while the need for higher input energy. When the atom is destroyed, the energy is released.
The use of lead bismuth eutectic mixture (lead, 44%, 56%) as a nuclear reactor coolant, because of its physical, chemical and thermodynamic characteristics, these characteristics can be the most perfect to meet the safety requirements of the reactor. During the operation of nuclear power plant, there is no problem of corrosion of structure material in the loop, and there is no problem of the standard of 10-15.
Bismuth is also used as a separate material for reactor coolant. Because the ability to absorb X rays and radiation is roughly equal to that of the lead, the absorption of the thermal neutron cross section is small and the melting point is lower, so the LMFR reactor is chosen as the carrier and coolant for the reactor fuel U235 and U233. Bismuth coolant is also used for nuclear submarines, the performance is better than sodium chloride. Bismuth can also be used as a protective device for nuclear fission devices. Lead bismuth cooled nuclear reactors have been equipped with a Alfa class submarine.
