The field that China uses nuclear power technology the earliest is martial industry. The navy at the beginning of 70 time approachs 20 centuries the first times official investment uses submarine of water caboodle nuclear power. From 1985 design of our country proper motion builds first phase of hill of the Qin Dynasty since group of electric machinery of nucleus of 300 thousand KW, build through own design early or late, introduced foreign technology means to build hill of Daya Bay the Qin Dynasty again 2 period, Qin Shan 3 period, mountain bay, Tian Wan in all 6 nuclear power plant, in all investment of group of 11 nucleuses electric machinery moves, total installed capacity achieves 8.7 million KW. Occupy the whole nation to generate electricity 2% of installed capacity. Our country plans installed capacity had nuclear report 2020 the building of 40 million KW group of nuclear electric machinery and 18 million in group of the electric machinery that build a nucleus, the scale that installed capacity of nuclear cable unit takes capacity of aircraft of electric power general assembly will be achieved 4% the left and right sides, namely from now on, average and annual the nuclear cable unit that creates two 1 million KW at least. In the nuclear power plant that already built, the hill that divide another name for Shaanxi province 3 period use Canadian heavy water caboodle outside, other all piles to press water. The parameter of power of stand-alone of cropland bay nuclear power plant that offers by Russia is the biggest, for 1.06 million KW. The reactor of fast neutron hyperplasia that the unit such as university of academy of science of Chinese nuclear energy, Tsinghua builds, caboodle of advanced caboodle, high temperature air cooling still belong to research experiment caboodle in home, after gaining experience, create spread greatly business caboodle. Those who deserve attention is exceed the 3rd generation to press water to pile AP600 of group of nuclear electric machinery, AP1000 to have higher moving security by what house company designs the United States on the west, its design was used be not active principle to wait like gravitational, convection, condensation, use as the driving force in safe system, reduced the active driving force such as report, fluid, gas greatly. At the same time valve makes dosage decreases 50% , pump decreases 35% , cable dosage decreases 80% , amount of facility of aseismatic grade requirement dropped 45% , power station birthday period can amount to 60 years (it is 30 ~ 40 years now) . But the model that run has not built on bound of preexistence of eye of this kind of nuclear power plant. Our country also is undertaking the research of the 3rd acting nuclear power plant and experiment work at present.
