The reporter learned from the National Nuclear Power Technology Corporation that "National Nuclear Power" has learned that a key technical test of the CAP1400 nuclear power plant of the national major science and technology special CAP1400 nuclear power demonstration project has passed the national verification. This will provide important support for the construction of the project.
This Multi Fuction Safety Vest is an upgraded version of the base vest, special vests for special industries. Such as flame fuction safety vest benefit from flame retardant reflective tape as well as limited flame
spread binding and can protect workers against occasional and brief
contact with small igniting flames, in circumstances where there is no
significant heat hazard and without the presence of another type of
heat. But it is necessary to know that fire resistance is not equal to
incombustibility; Waterproof Safety Vest can protect the wearer from getting wet and keep warm.

According to insiders, on July 5th, the performance test of the passive core cooling system of the large-scale advanced pressurized water reactor nuclear power plant CAP1400 nuclear power plant was called "ACME" successfully completed the last National Nuclear Safety Administration witness test - CAP16 working condition test. The person also said that the ACME gantry has now completed a series of design basis accidents or over-design basis accident conditions including the National Nuclear Safety Administration witness test. The completed tests have achieved good test results and can fully and fully verify the safety performance of the CAP1400 nuclear power plant, providing important support for the final nuclear safety review and demonstration project approval of the CAP1400 nuclear power plant.
It is understood that as one of China's 16 major scientific and technological projects, the main tasks and overall objectives of the CAP1400 nuclear power plant are: digesting and absorbing on the basis of the AP1000 third-generation nuclear power technology that has been determined by the state, and fully grasping the first sign based on passive technology. The third-generation nuclear power technology, and further research and development of large-scale advanced pressurized water reactor technology with China's independent intellectual property rights, built a large-scale advanced pressurized water reactor nuclear power plant major special CAP1400 nuclear power plant.
Domestic nuclear power industry chain welcomes development opportunities
From the perspective of the industrial chain, nuclear power construction includes fuel suppliers, equipment suppliers, power auxiliary industry groups, nuclear power transmission and distribution enterprises of power generation enterprises, etc.: First, upstream links, including nuclear fuel and raw material production; The middle reaches, including nuclear reactors and nuclear power core equipment, do not include nuclear reactor manufacturing and nuclear power auxiliary equipment manufacturing; third, the downstream links, mainly including nuclear power plant construction and operation and maintenance. With the advancement of China's basic nuclear physics research, the constraints on the development of nuclear power will be effectively resolved, and the entire industry chain will benefit.
An upstream industry - nuclear fuel
At present, there are few enterprises engaged in nuclear power raw materials in China, and several companies with large production scale are listed in the Shanghai and Shenzhen stock markets. Such as the production of zirconium products, sublimation Baike, Oriental Zirconium; Lantai Industry, which produces nuclear grade sodium; Fangda Carbon, which produces nuclear graphite, and Sinosteel.
Second mid-stream industry - nuclear reactor manufacturing, nuclear power core equipment manufacturing without nuclear reactors and nuclear power auxiliary equipment manufacturing
1. Nuclear reactor
At present, nuclear reactors are currently in the transitional stage of the third-generation technology and the fourth-generation technology. They are mainly controlled by the Westinghouse AP1000 series nuclear reactors, the French Areva EPR series nuclear reactors, and the Russian VVER1000 series nuclear reactors. China has introduced, digested, absorbed and innovated. It has also gradually mastered relevant technologies and developed CNP series and CPR1000 nuclear reactors with independent intellectual property rights.
2. Nuclear power core equipment does not contain nuclear reactor manufacturing
The core equipment of nuclear power includes nuclear island equipment and conventional island equipment. In general, nuclear island equipment accounts for about 45% of equipment investment, conventional island equipment accounts for 30%, and auxiliary equipment accounts for about 25%. Therefore, according to the equipment investment of about 400 billion yuan in 2009-2020, it is estimated that during this period, the nuclear island equipment market capacity is about 180 billion yuan, the conventional island equipment market capacity is about 120 billion yuan, and other auxiliary equipment market capacity is about It is 100 billion yuan. Most of the enterprises producing nuclear island equipment and conventional island equipment in China are listed in Shenzhen and Shanghai, such as Dongfang Electric, Shanghai Electric and Harbin Electric.
3. Nuclear power auxiliary equipment manufacturing
Nuclear power auxiliary equipment includes nuclear island internal components, pressure vessels, nuclear island lifting equipment, nuclear island circulating cooling devices, nuclear grade valves, air cooling equipment, nuclear power plant transformers, other equipment and materials. This link is the lowest link for domestic enterprises to enter nuclear power barriers. Therefore, the localization of nuclear power auxiliary equipment in China is relatively high. Most of the powerful enterprises are listed in Shanghai and Shenzhen, such as the offshore and heavy industry for the production of nuclear island internal components; Shanghai Electromechanical and Taiyuan Heavy Industries of the equipment; shield environment for the production of nuclear island circulating cooling devices; nuclear technology for the production of nuclear-grade valves; enterprises that produce air-cooled equipment have air conditioning and superior high-tech; special transformers and transformers for the production of nuclear power plant transformers Weibao has changed and so on.
