Total nuclear power valve investment will reach 7 billion by 2020

The development of domestic nuclear-level valves started in the early 60s. At present, after decades of efforts, China has formed a certain scale of nuclear valve design, experiment, manufacturing, testing capabilities, and provides a large number of nuclear and non-nuclear-level valves for the Qinshan Nuclear Power Plant Phase I and Phase II construction. It has made important contributions to the localization of nuclear power valves.

The nuclear power valve refers to the valve used in the nuclear island N1 of the nuclear power station, the conventional piston of the plunger pump, and the BOP system of the power station auxiliary facilities. From the nuclear power safety level is divided into nuclear safety level, level, level, non-nuclear level, where the highest level of nuclear safety requirements. Nuclear power valves use a large number of medium transmission control devices in nuclear power plants and are an indispensable part of the safe operation of nuclear power plants.

According to statistics, a nuclear power plant with two 1 million KW units has 30,000 valves. According to the valve configuration, the cut-off valve accounted for 33.6%, the diaphragm valve accounted for 26.2%, and the ball valve accounted for 12.8%. These three accounts for 72.6% of the nuclear island valves. From the perspective of the distribution of safety grades, only 2.3% of nuclear grades, 52% of nuclear and grade grades, and 45.7% of non-nuclear grade grades.

The proportion of investment in nuclear power plants in nuclear power plants accounts for about 1.6% of the construction price of nuclear power plants. According to Lingao Australia's two million KW unit nuclear power station construction price of 3.5 billion US dollars, the valve investment is 56 million US dollars, equivalent to about 460 million yuan. According to the national nuclear power development plan, the total investment in new nuclear power plants will reach more than 7 billion yuan by 2020 (if the material and other price increase factors are taken into account, it will reach nearly 10 billion yuan). Such a huge market has provided China with a good opportunity for development in the valve industry, and it is also a severe test for the Chinese valve industry.

According to the excellent development of China's nuclear power plants and the status quo of nuclear power valve development, in order to realize the rapid development of nuclear power, localization of nuclear power valves, individuals believe that China's valve companies, industries and countries should take measures to resolve several issues affecting the localization of nuclear power valves.

1. As soon as possible to supplement and perfect China's nuclear power valve technical standards and norms. The existing EJ, GB, ASME, RCC-M standards to supplement and improve, in line with national conditions and improve operability, in order to facilitate the domestic nuclear power valve in the design, material selection, inspection and other aspects can be achieved in the domestic.

2. Integrate the experiments, testing and appraisal equipment and capabilities of nuclear valves in the domestic valve industry, share resources, avoid duplication of investment, and speed up the development of nuclear power valves.

3. Strengthen personnel training and the introduction of technology to absorb and absorb. Improve nuclear power valve design capabilities and levels.

4. Increase investment in software and hardware to ensure advanced design and manufacturing methods, as well as dependable parts and machine assembly.

5. Strengthen the welding, non-destructive testing, heat treatment and other special technical personnel training assessment. Research and adopt advanced technology to make parts manufacturing quality meet the requirements of design drawings and standards.

6. Carry out employee education and training in awareness of nuclear safety, strengthen the quality management of nuclear power valve design and manufacturing, and improve management.
