World's first AP1000 nuclear power units--Zhejiang sanmen nuclear power station unit 1th, December 15 to enter the final stage of testing, which is also the last one before the unit loading nuclear fuel work, according to the plan the nuclear power units is expected in 2017 grid-connected power generation in the first half.
World's first testing of AP1000 nuclear power units to a close
Zhejiang sanmen nuclear power station unit 1th capacity 1.25 million-kilowatt, used by three generations of the AP1000 nuclear power technology, than the current widely used second generation nuclear power plant safety indicators improved in recent times, and nuclear power units can be extended by 20 years, up to 60 years.
Compared with the running of power plant equipment AP1000 system did a lot of "subtraction" pipe by 80%, cable 70%, significantly reduce the probability of damage, failure of the link each of these devices, improve the reliability of the entire plant. AP1000 passive design concept is used, that is, when a serious accident occurs, without human intervention, to ensure nuclear security for up to 72 hours.
More advanced major projects in nuclear power demonstration project will start
Not only that, the AP1000 nuclear technology on the basis of China's independently developed the third generation of pressurized water reactor nuclear power project CAP1400 demonstration project has been through the national nuclear safety administration safety review, is expected in the first quarter of 2017 granted in rongcheng, Shandong province shidao Bay under construction.
The CAP1400 nuclear power construction unit, China through the introduction, digestion and absorption of advanced-generation AP1000 nuclear power technology in the world of design concept, developed with China's own intellectual property rights, more advanced nuclear power technology, is one of the 16 State major science and technology projects. Compared with the AP1000 CAP1400 nuclear reactors and all the new design master.
CAP1400 nuclear reactors, equipment, safety systems are subject to a large number of experiments, not only more powerful, while further strengthening the plant against earthquakes, outside of extreme natural disasters such as flooding. In addition, the CAP1400 nuclear power unit's capacity reached 1.5 million-kilowatt, greater capacity, better economy.
Nuclear power independence drive upgrade
From the introduced AP1000, r CAP1400 nuclear power in China in more than 30 years, done from a technical introduction, digestion and absorption into the new development, in order to upgrade the overall level of China's equipment manufacturing industry, nuclear power equipment and the upgrading of key materials provide important technical support.
Tang Weibao, the Chief Engineer of the Shanghai Electric's nuclear power group in the field of nuclear power engineering has worked for more than 30 years, after graduating from University in 1982, he took part in China's first nuclear power plant – construction of the first phase of qinshan nuclear power units.
Foreign nuclear power technology to China was blocked due to lack of experience in building, equipment manufacturing capacity is weak, Tang Weibao and colleagues only stones. After the reform and opening up, qinshan, Daya Bay phase I projects with foreign cooperation, on the basis of the introduction of digestion and absorption, and embarked on a fast track for China's nuclear power development.
Tang Weibao: "our equipment capability with overseas than at present, has reached the world's top level. Like the deep hole processing, support, installation, these are key technologies of steam generator, I should say we have fully mastered the manufacturing technology of the third generation nuclear power. ”
Now, three generations of the Chinese independently developed nuclear technology "CAP1400", "Hua long first" appearance, overall performance of the world's top level, while three key nuclear power equipment 85% above are made, China has achieved.
China's nuclear power capacity-building the world's leading
After more than 30 years of uninterrupted accumulation of experience in nuclear power plant construction and operation, China's nuclear power construction has been in the forefront of global. Now, the AP1000 nuclear power units in China, United States a total of 8 units are under construction, Zhejiang sanmen nuclear power plant in China, the Shandong Haiyang nuclear power plant has two units, three unit first in building the fastest, grid-connected power generation. Nuclear power capacity-building of excellent, rigorous technical security reviews, making three unit first, as "the world's first" at the same time, can provide other AP1000 units around the world with lots of feedback and experiences.
Sanmen nuclear power plant in "the world's first reactor" is just a microcosm of China's nuclear power capacity-building. Upgrading depend on advanced technology research and development support for capacity-building. China's own third generation nuclear power technology "CAP1400," for example, in order to test its technical indicators to test its system, equipment can meet the strict requirements for nuclear security and nuclear power engineering, "CAP1400" put through numerous tests before.
Now, nearly 30 nuclear power plant under construction in China, 42% of the total global installed capacity of nuclear power units under construction, construction world. At present, China's nuclear power companies are actively promoted in Europe, Latin America, Africa and other nuclear projects in nearly 20 countries, among them, Turkey and the United Kingdom, and Argentina and so there is good news, "CAP1400", "Dragon of China first," as a representative of China's own third generation nuclear power technology have achieved "go". After high-speed rail, nuclear power is expected to be out another China-made brand products.

全球首台AP1000核电机组——浙江三门核电站1号机组，12月15日正式进入性能测试的最后阶段，这也是该机组在装入核燃料前的最后一项工作，按照计划该核电机组预计2017年上半年并网发电。
全球首台AP1000核电机组测试进入尾声
浙江三门核电站1号机组单机容量125万千瓦，所采用的三代核电技术AP1000，比目前普遍使用的二代核电机组在安全指标上提高了近百倍，并且核电机组的寿命可以延长20年，达到60年。
与正在运行的电站设备相比，AP1000在系统构建中做了大量的“减法”，管道减少80%、电缆减少70%，大幅减少各个设备环节发生损坏、故障的概率，提高了整个核电站的可靠性。AP1000还采用了非能动的设计理念，即在发生严重事故时，无需人工干预，能保证核岛安全长达72小时。
更先进的核电重大专项示范工程将开工
不仅如此，在AP1000核电技术的基础上，中国自主研制的第三代压水堆核电重大专项CAP1400示范工程，目前已经通过国家核安全局的安全评审，预计于2017年一季度获批在山东荣成石岛湾开工建设。
即将建设的CAP1400核电机组，是中国通过引进、消化、吸收世界先进三代核电技术AP1000的设计理念，自行研发的具有中国自主知识产权、功率更大的先进核电技术，也是中国16个国家重大科技专项之一。跟AP1000相比，CAP1400对核反应堆及所有主设备都进行了全新的设计。
CAP1400核电技术的反应堆、主设备、安全系统都经过了大量的实验验证，不仅功率更大，同时进一步增强了核电站抗击地震、外部水淹等极端自然灾害的能力。此外，CAP1400核电机组的单机容量达到150万千瓦，能力更大，经济性也更好。
核电自主化带动产业升级
从引进AP1000，到自主研发CAP1400，中国核电在三十多年的时间里完成了从技术引进、消化、吸收到再创新的发展历程，为中国装备制造业的整体水平提升、核电装备和关键材料的升级换代提供了重要技术支撑。
上海电气核电集团总工程师唐伟宝在核电工程领域工作了30多年，1982年大学毕业之后，他就参加了中国第一台核电机组——秦山一期核电机组的建设。
当时国外核电技术对中国实行封锁，由于缺乏建设经验，设备制造能力薄弱，唐伟宝和同事们只能摸着石头过河。直到改革开放以后，秦山二期、大亚湾一期等项目与国外展开合作，在引进消化吸收的基础上，中国的核电发展走上了快车道。
唐伟宝：“目前我们的装备能力跟国外比，已经达到了世界顶级水平。比如像深孔加工、支撑板安装，这些都是蒸汽发生器里面最为关键的技术，应该说我们已全面掌握三代核电的制造技术。”
如今，中国自主研制的三代核电技术“CAP1400”、“华龙一号”相继问世，整体性能达到世界顶尖水平的同时，三代核电关键设备85%以上都已经实现了中国国产。
中国核电建设能力全球领先
经过30多年不间断积累的核电工程建设和运营经验，目前中国的核电建设能力已经走在了全球前列。现在， AP1000核电机组分别在中国、美国共有8台正在建设，中国浙江三门核电站、山东海阳核电站各有两台，其中三门一号机组建设进度最快，即将并网发电。过硬的核电建设能力，严格的技术安全审查，使得三门一号机组作为“世界首堆”的同时，能够为全球其他AP1000机组提供大量的反馈信息和建设经验。
三门核电站的“全球首堆”，只是中国核电建设能力的一个缩影。建设能力提升离不开先进技术的研发支持。以中国自主三代核电技术“CAP1400”为例，为了测试其技术指标，检验其系统、设备能否满足严格的核安全和核电工程要求， “CAP1400”投入建设之前经过了无数的测试。
当下，中国在建核电机组有近30台，占全球在建核电机组装机容量的42%，建设规模全球第一。目前，中国的核电企业正积极推动与欧洲、拉丁美洲、非洲等近20个国家的核电项目合作，这其中，土耳其、英国、阿根廷等方面都传来了好消息，以“CAP1400”、“华龙一号”为代表的中国自主三代核电技术纷纷实现“走出去”。核电有望成为继高铁之后走出去的又一中国制造品牌产品。
