Carbon neutrality is expected to continue to stimulate the nuclear power industry chain, and the nuclear power valve industry will continue to benefit.

In the white paper "China's Energy Development in the New Era", the "Carbon Neutrality Roadmap" shows the world China's actions to address climate change. and assume the responsibility of a major country. Shen Wanhongyuan believes that in the context of carbon neutrality, South China provinces generally lack high-quality wind power and photovoltaic resources. Nuclear power utilization hours are flexibly controllable, resource constraints are low, site selection is relatively flexible, and power generation has no carbon emissions. It is expected to become the leading choice for thermal power in South China provinces. An ideal alternative, nuclear power approval is expected to be accelerated during the "14th Five-Year Plan" period.

Nuclear power is one of the three basic power generation methods that carry the basic power load of the power grid. It is efficient, clean, safe and economical. As of the end of 2019, my country had 47 nuclear power units in operation, with a total installed capacity of 48.75 million kilowatts, ranking third. In early September 2020, the Standing Committee of the State Council approved the construction of four new nuclear power units, including Zhejiang Sanao and Hainan Changjiang Phase II, with a total effective investment of more than 70 billion yuan, marking the normalization of approval of new nuclear power projects.

Based on the current status of nuclear energy development and national energy demand, industry insiders predict that my country will maintain 6 to 8 new nuclear power units approved for construction every year in the next few years, and the nuclear energy industry chain is expected to continue to benefit. Among them, the nuclear power valve industry will usher in huge market opportunities.

Nuclear power valves refer to valves used in the nuclear island (NI), conventional island (CI) and power plant auxiliary facilities (BOP) systems in nuclear power plants. Its main function is to control and regulate the flow, temperature, pressure and flow direction of the medium in the pipelines of the nuclear power plant. It also protects other pressure vessels such as pressure stabilizers and evaporators.

There are a large number of valves used in nuclear power plants, including gate valves, globe valves, diaphragm valves, safety valves, ball valves, main steam valves, blast valves, etc. It is reported that a pressurized water reactor nuclear power plant with a million-kilowatt unit uses more than 30,000 valves. In recent years, in order to alleviate domestic energy shortages and environmental pollution problems, our government has actively developed a series of clean energy industries such as nuclear power, especially the nuclear power industry, which has provided good conditions for the expansion of my country's nuclear power valve market demand. In 2019, my country's nuclear power valve market size has grown to more than 5.5 billion yuan, and it is expected to still have broad growth potential in the future.

With the gradual improvement of my country’s entire nuclear power industry chain and the continued development of domestic production technology, some parts of our countryThe company has gradually broken the nuclear first-class valve market that was originally monopolized by foreign manufacturers, and can independently design and produce gate valves, globe valves, check valves, ball valves, butterfly valves, regulating valves, throttle valves, diaphragm valves, and bellows globe valves. and a series of nuclear safety grade valves, the market competitiveness of domestic enterprises has been greatly improved.

For example, Jiangsu Shentong, as one of the first domestic companies to enter the field of nuclear power valves, has won the bid for nuclear-grade butterfly valves, More than 90% of orders for nuclear grade ball valves. In addition, in terms of nuclear power spent fuel reprocessing, Jiangsu Shentong has received a total of about 370 million yuan in orders for 200-ton nuclear fuel reprocessing projects, making a huge contribution to the independence of my country's nuclear power construction equipment.

It is foreseeable that the strategic goal of carbon neutrality is expected to accelerate the normalization of my country's nuclear power construction. The growth of nuclear-grade valves brought about by nuclear power construction and the demand for spent fuel reprocessing brought by the continued increase in domestic nuclear power units put into commercial operation will bring huge development opportunities to nuclear energy equipment companies.
