Our third generation of nuclear power plant are shandong construction of independent innovation in zhejiang
|
At present, China's third generation of independent innovation of zhejiang sanmen is nuclear power project in construction and the shandong haiyang electricity running the second generation of nuclear power units, prevent and ease than the reactor core of melting become design requirements, but it must be as second generation is also blessed island nuclear recent nuclear accident exposed weaknesses. Yesterday, our nuclear reactor and nuclear power engineering experts, "" father of Chinese nuclear OuYangYu academician visit China science and technology museum, introduce the world nuclear power technology hall and development situation of the development of nuclear power in China situation.
According to OuYangYu academician introduction, our third generation plant equipped with reservoir, this will be the "big tank" in emergency situations can release a large amount of water cooling, etc, so as to achieve the emergency needs.
Through summarizing the experiences and lessons, and the United States, Europe and the international atomic energy agency are issued new rules, prevent and ease the serious accident as design must request, fulfill the requirements of the nuclear power station called third-generation nuclear-power plants.
According to OuYangYu academician introduces, at present, the world technology more mature, can build third-generation nuclear power units (the design, basically have American Westinghouse AP1000 (PWR) and ABWR (boiling water reactor), as well as Europe's EPR (PWR) models, they occur probability of serious accidents than the second generation nuclear power units are little more than 100 times. The United States, France and other countries has publicly, will not be built second-generation nuclear power units, only construction third generation nuclear power units.
OuYangYu academician said that China has 13 new second generation of nuclear power units are running power generation, future focus on building on the third generation nuclear power units in China, and developed a Chinese brand of independent intellectual property of the third generation advanced nuclear power units. Therefore, the state council decided to zhejiang sanmen and shandong haiyang two nuclear power project as a third-generation nuclear power on engineering, construction significance four sets of third generation the Westinghouse AP1000 PWR nuclear power units. Long-term technology development plan for state already will "large advanced PWR" as major projects.
Background material
The second generation plant but against serious accidents
OuYangYu academician said, the 1970s, when the oil prices of energy crisis triggered by a nuclear power development, at present, promote world commercial operation of the 400 units built most in this period, called the second generation of nuclear power units. The experts engaged in nuclear power to the second generation plant, when a reflection that happened the reactor core of melting and radioactive substances into environmental releasing such a serious accident, needn't have little chance to prevent and ease a serious accident facilities as design must request, therefore, the second generation of nuclear deal with a serious accident measures are thin. |
