Introduction to AP1000 nuclear power
  
AP1000 nuclear power technology, china's third generation of nuclear power independent technology. Introduction, digestion, absorption and re-innovation and independent innovation, in the world, china take the lead in mastering five key technology of the third generation nuclear power AP1000 that laid the solid fundation for  promoting china nuclear power technology level across the whole and realizing china third generation nuclear power AP1000 automatization and large production. AP1000 nuclear technology is currently only third generation nuclear power through the U.S nuclear regulatory commission final design approval and it is currently the safest, most advanced commercial nuclear power technology in global nuclear power market.

Working principle
AP1000 is a kind of advanced "non active type  PWR nuclear technology". Nuclear fuel made by uranium occured fission in the "reactor" equipment to produce lots of heat. Then the water under high pressure brought out the heat to produce the steam in the steam generator. Steam promote steam turbine with generator rotated, electricity is produced continuously, and through the grid to in all directions. Using the principle of nuclear power technology is PWR nuclear power technology.

Core technology
Makes pressure shell of mass concrete one-time whole pouring technology, nuclear island CVBH complete set technology, module design and manufacturing technology, main pipe manufacturing technology, pressure shell of the equipment large-scale forging manufacturing technology.

Main features
1. The greatest characteristic of AP1000 is succinct design, easy for operation, and make full use of many "the active safety system", such as theory of gravity, natural circulation, polymerization. It is more simple and effective than the traditional PWR safety system.
2. Further improve the safety of the nuclear power station, at the same time, it also can significantly reduce the construction of nuclear power units and long-term operation costs.
3. In the AP1000 construction process, module technology can be used. Multipoint advance together to implement the construction, that greatly cut the nuclear power units construction period. AP1000 from construction to load raw materials to start producing electricity, the fast only need 36 months. It is clear to the construction cost saving advantages.

Development history
The AP1000 is Westinghouse development and extension on the basis of AP600 technology. With the design characteristics "the initiative", AP600 began in 1991. Westinghouse first tried to promote the nuclear power station technology in the 2 aspects of economic and safety level to a new height for keeping technology the leading superiority in the nuclear power field. In 1998, AP600 won USNRC "the final design standard" , but with the constant change of world power market, price drop to nuclear power new goals per degree 3 cents and AP600 can't meet the requirements. Therefore Westinghouse start the AP1000 development work, the goal is cheaper, safer, more effective nuclear reactor technology, in order to improve its competitiveness in nuclear power market.

Due to AP1000 emerged from AP600, so the development process accelerated greatly. By means of improving design to reach compatibilization purpose, it significantly increase the generate electricity power, at the same time kept the original system security and simplicity. From AP600 to AP1000, it passed 15 years development and perfection. Wisdom mentioned that: during the many years development, a lot of Chinese engineering and technical personnel are also involved. As the most competitive technology in the nuclear power market, AP1000 should apply to China's nuclear power units construction. For both sides of China and America, it is true win-win cooperation. China will rely on the advanced nuclear power technology to better meet the growing energy needs. While cooperation with China, on the one hand, it will create numerous jobs for America. On the another hand, it provide the good chance for exporting the American products, technology and service.

Technical characteristics
1. The world market existing the safest, most advanced, the verified nuclear power station (conservative probability risk assessment (PRA): the reactor core damage probability is negligible 2.5x10-7).
2. The only third generations of nuclear power plants get USNRC final design approval (FDA).
3. Based on the standard Westinghouse pressure water reactor (PWR) technology, this technology has already achieved more than 2500 in the success of the times of reactor operation.
4. 1100 MWe design is ideal for providing basic load capacity for power generation.
5. Modular design is helpful for standardization and improving the construction quality.
6. More economic operation (less concrete and steel, less components and systems, means less installation, testing and maintenance ).
7. More simple operation ( equipped with the industry's most advanced instrument and control system ).
8. Comply with the requirements of American users required document (URD) to new generation commercial reactor.
