The construction of nuclear level digital I & C platform has been significantly accelerated through the Review

recently, the construction of domestic nuclear power units has been significantly accelerated. The first inching of the four reactor coolant shield main pumps of Haiyang unit 1 was successful, and the first cold hydrostatic test was completed. The function test of the equipment gate of the world's first cap1400 unit is successful, and the construction and approval of the third generation nuclear power unit in China is expected to be further accelerated

SASAC Weibo disclosed that recently, the nuclear level digital instrument control platform "harmony system" independently developed by CGNPC passed the review of the International Atomic Energy Agency. It is reported that in October, 2010, China Guangdong Nuclear Power Group successfully released the nuclear DCS product "harmony system". At present, the system has been applied in many nuclear power projects, such as Yangjiang Nuclear Power Plant Units 5 and 6, Hualong 1 demonstration project, Tianwan Nuclear Power Plant Units 5 and 6, etc

as the nerve center of nuclear power plants, the "harmony system" of digital instrument and control products for nuclear power plants developed by CGNPC passed the independent review of IAEA, which means that the system has been recognized by the world authoritative organization, which is of great significance for China's nuclear power equipment manufacturing industry to enhance its global influence and promote its "going global" development strategy. Reviewing and benchmarking in accordance with the international nuclear safety system will help further improve and optimize the design of the "harmony system" and enhance the international competitiveness of the additive manufacturing industry as China's independent nuclear power equipment brand

the main functions of the "harmony system" include the protection and control of nuclear reactors, the real-time monitoring of various parameters during the operation of nuclear power plants, and the automatic judgment of operation status. Once an abnormality occurs, the system can realize safe shutdown in the shortest time and avoid the impact on the external environment, which plays an important role in ensuring the safe, reliable and stable operation of nuclear power plants. It is particularly obvious in East China

The Research Report of securities companies believes that the approval of new nuclear power units and equipment bidding that will be launched in the second half of the year will accelerate the implementation of order requirements. In addition, the promotion of localization of key nuclear power materials will bring room for import substitution. According to the medium and long-term development plan of China's nuclear power, by 2020, the installed capacity of operating nuclear power will reach 58million kW, about 30million kW under construction, and the investment in nuclear power equipment will reach 360billion yuan. The market segments such as nuclear island, conventional island and auxiliary equipment will be rapidly expanded. Today, with serious white pollution and global plastic ban

from the perspective of the overall development of the industry, by the end of last year, China had operated nearly 30 nuclear power units with a total installed capacity of 28.31 million KW; There are 24 nuclear power units under construction, with a total installed capacity of 26.72 million KW. Among them, the number of nuclear power units under construction ranks first in the world, and the total number of units ranks third in the world. In the next five years, China needs to increase at least 30 nuclear power units in operation and at least 14 nuclear power units under construction. The agency predicts that the investment in nuclear power equipment will reach 360billion yuan by 2020

recently, the construction of domestic nuclear power units has accelerated significantly. The first inching of the four reactor coolant shield main pumps of Haiyang unit 1 was successful, and the first cold hydrostatic test was completed. The function test of the equipment gate of the world's first cap1400 unit is successful, and the construction and approval of the third generation nuclear power unit in China is expected to be further accelerated. With the tackling of the AP1000 main pump problem at the end of last year, the construction progress of Sanmen and Haiyang units has been significantly accelerated since the beginning of this year, which will have a positive impact on the approval and transposition of new units and bidding that will be opened successively in the second half of the year, and relevant equipment enterprises will obtain substantial order requirements

according to the comprehensive research report of securities companies, Jiangsu Shentong is the leading manufacturer of nuclear power valves in China. It has obvious competitive advantages in the field of nuclear power ball valves and butterfly valves, and its market share has been close to 100%. Last year, the company obtained a total of 414 million nuclear power orders, and it is expected that the new orders in 2016 will be basically the same as last year. As new orders for nuclear power projects began to be delivered in succession, the company expects the net profit in the first half of the year to increase by 30%-50% year-on-year. Jiuli special material has the business of nuclear power evaporator, and its market share ranks in the forefront of the industry. It has successively supplied nuclear tube materials for 43 units of nuclear power plants at home and abroad. Taiwan nuclear power is mainly engaged in the R & D, manufacturing and sales of special nuclear power equipment, special materials, and large castings and forgings. Among the 27 nuclear power units under construction, the company provides 13 units of nuclear island main pipeline equipment, with a market share of about 50%.
