Nuclear Power Construction Drives Opportunities and Challenges for Nuclear Power Valve Market

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 security level is divided into nuclear safety level, level, level, non-nuclear level. The highest level of nuclear safety is required. 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.
