Information
Since Premier Zhou Enlai approved the design plan for the construction of a PWR with a power of 300,000 kilowatts in March 1974, my country's nuclear power research and development and design and construction work has gone through thirty years. At present, there are already 9 nuclear power units in operation in mainland my country, with an installed capacity of 6,990MW. By the end of this year, there will be 11 units in operation with a total power of 9,110MW. In 2004, the State Council has approved the construction of 8 nuclear power units. Four of them are second-generation improvement projects, and four are dependent projects for third-generation nuclear power autonomy. In 2005, it was decided to carry out the pre-construction work of four second-generation improved units. Nuclear power has entered the stage of development in our country from the beginning.
When Premier Zhou approved the nuclear power plan for the first 300,000-kilowatt nuclear power plant, he pointed out that the purpose of building this nuclear power plant is not only to generate electricity, but more importantly, to master technology, accumulate experience, and train through independent research, design, construction, and operation. Personnel, laying a good foundation for the future development of nuclear power in our country. Today, this goal has been basically achieved. After the construction of three bases in Qinshan, Daya Bay (including Lingao) and Tianwan, and the training of general contract export of nuclear power units abroad, my country’s nuclear power team has the ability to independently design nuclear power units of 300,000 kilowatts and 600,000 kilowatts, and is basically capable of independent design 1 million kilowatt nuclear power plant. However, our technical level is still at the level of nuclear power technology of the second generation of pressurized water reactors in the world. After extensively listening to the opinions of various relevant departments and experts, my country’s central leadership made a decision that my country should actively promote the development of nuclear power, and pointed out that in the future, my country’s nuclear power development should implement the autonomy and localization of large-scale units as soon as possible. ; Adopt advanced technology, unify the technical route & rdquo; policy. Therefore, we should appropriately continue to build some second-generation improved units, and at the same time improve the safety and economy of nuclear power as the fundamental goal, and realize the upgrading of my country’s nuclear power technology as soon as possible, that is, from the second generation to the third generation. Level; through the combination of independent development and imported technology, the goal of independent design and construction of the third-generation million-kilowatt large-scale pressurized water reactor nuclear power unit will be reached as soon as possible, and an advanced, standardized, batch-building industrial scale will be formed, and high-quality and high-speed development of nuclear power . At the same time, we should also see that the internationally mature third-generation nuclear power plants still have shortcomings and room for development. For example, the passive safety system of AP-1000 is advanced, but its stand-alone capacity can only reach 1200MW, which has room for development; although the stand-alone power of EPR has reached 1600MW, its active safety system is quite complicated and it is not the direction of development. . my country has selected AP-1000 as the model for the third-generation nuclear power independent project. While cooperating with foreign manufacturers to digest and absorb imported technologies to build the third-generation nuclear power unit, we should also address its shortcomings and developments. Space, set up a special project to improve and innovate at the same time, and develop a more advanced large-scale nuclear power unit with a Chinese brand with my country’s intellectual property rights. To this end, my country’s mid- and long-term science and technology development plan has listed "large advanced pressurized water reactors and high-temperature gas-cooled reactor nuclear power plants" as major special projects. This is a major project that the country must make every effort to guarantee, and it will be built in batches after successful industrialization.
“Large advanced pressurized water reactor” further development of the major project should be the fourth-generation supercritical water-cooled reactor. Its power generation thermal efficiency can reach 44%, and the single electromechanical power can reach 1700MW. In this regard, we should also do some forward-looking pre-research appropriately.
In short, our country's nuclear power is facing an unprecedented good development opportunity. We must cherish this opportunity, work hard to do a good job, and make due contributions to the development of my country's nuclear technology and nuclear industry and the international use of nuclear energy.

Introduction to AP1000 major equipment
2021-12-27
From the 50s to the early 1960s the Soviet Union, the United States and other construction of the first single capacity of about 300MWe nuclear power plants, such as the United States and the British port of Hipigong 1 nuclear power plant, France's Chouz (Chooz) nuclear power plant, Germany Obrigheim (Obrigheim) nuclear power plant, Japan's Meibang 1 nuclear power plant. The first generation of nuclear power plants belong to the prototype reactor nuclear power plant, the main purpose is to test the demonstration form to verify the feasibility of its nuclear power in the implementation of the project.
Second generation nuclear power plant:
The second generation of nuclear power plants is mainly to achieve commercialization, standardization, serialization, batch, to improve the economy. From the late 1960s to the 1970s, a large number of standardized and serialized nuclear power plants with a single stand-alone capacity of 600-1400MWe were built. Model 212 (600MWe, two-ring pressurized water reactor, represented by American Westinghouse) , A 12-foot fuel assembly), a Model 312 (1000MWe, 3-loop pressurized water reactor, a core with 157 cartridge assemblies, a 12-foot fuel assembly), Model 314 (1040MWe, 3-ring pressurized water reactor, The Model 412 (1200MWe, 4-ring pressurized water reactor, the core has a 193-box assembly, uses a 12-foot fuel assembly), a Model 414 (1300MWe, 4-ring pressurized water reactor, The reactor has a 193 cartridge assembly with a 14-foot fuel assembly), the System80 (1050MWe, 2 loop pressurized water reactor) and a large number of boiling water reactors (BWR) can be included in the second generation nuclear power plant category. France's CPY, P4, P4 '' also belong to Model 312, Model 414 a class of standard nuclear power plant. Japan, South Korea has also built a number of Model 412, BWR, System80 and other standard nuclear power plants.
The second generation of nuclear power plants is currently running the world's 439 nuclear power plants (September 2007 statistics) main unit, with a total installed capacity of 372 million kilowatts. Also a total of 34 nuclear power units under construction, with a total installed capacity of 278 million kilowatts. After the triennial nuclear power plant and the Chernobyl nuclear power plant after the accident, countries on the operation of the nuclear power plant in varying degrees of improvement in the safety and economy have improved to varying degrees.
