In 2011 Japan 3· 11 earthquake that triggered the Fukushima nuclear accident occurred after the public for the construction of nuclear power, especially inland nuclear power construction concerns increased significantly, especially concerned about the effects of nuclear power plant operation on downstream water quality and serious accidents of water resources safety influence. The relevant government departments in China immediately conduct comprehensive safety checks on the domestic and under construction nuclear power projects, and meanwhile suspend the approval of new projects and projects that have been carried out in the preliminary stage.
In the last years of the domestic nuclear power safety inspection is completed, the "nuclear safety &ldquo 12th Five-Year; ” planning", "nuclear power development plan" in 12th Five-Year “ ” by the executive meeting of the State Council in December 25th last year by the signal process of domestic nuclear power development began to restart. Recently, the nuclear power industry in the frequent hair to restart the inland nuclear power, the National Energy Commission Expert Advisory Committee Deputy Director Du Xiangwan recently also said that inland nuclear power will start steadily. The National Energy Agency article also said that there is no essential difference in the requirements for the development of nuclear power in the inland and the coastal areas. Domestic nuclear power has maintained a relatively strong momentum of development. China's nuclear power industry is ushering in new opportunities for development, and is rapidly rising. Related nuclear power equipment &mdash, &mdash, pump valves and supporting products also enter the nuclear power industry circle.
Nuclear energy enters the stage of large-scale development
Nuclear energy, as a clean, safe and efficient new energy, has become an important energy source for the whole world to promote low-carbon sustainable development. The development prospect of nuclear energy is more and more extensive. The development of nuclear power has become a strategic move for China to implement energy development strategy, readjust and optimize energy structure, transform economic development mode, and achieve energy saving and emission reduction. With the implementation of China's energy saving and emission reduction policies and the implementation of the long-term development plan of nuclear power, nuclear energy will also occupy more share of China's energy structure.
At present, there are 17 nuclear power plants running in China, with a total installed capacity of 14 million 700 thousand kilowatts, and 29 nuclear power plants under construction, with a total installed capacity of 30 million 570 thousand kilowatts. China has become one of the focuses of global nuclear power development. It is estimated that by 2020, the installed capacity of nuclear power in mainland China will reach 58 million kilowatts, and the nuclear power in construction will reach 30 million kilowatts. In the next year, the new nuclear power plant will be maintained at 4 to 6 units. Nuclear power will enter the stage of systematic and large-scale development.
Under the situation of large-scale nuclear power construction, the localization and independence of nuclear power engineering construction is constantly advancing. The capacity of design and design management, procurement and equipment supervision, construction management, commissioning and startup is continuously improving, which has strong engineering general contracting capacity. Construction and installation enterprises are actively adapting to the requirements of nuclear power reactor construction and multi project management, ensuring the quality control, schedule and investment of nuclear power projects are well controlled.
Pump and valve enterprises develop with the aid of nuclear power
In the field of nuclear power equipment and related industries, nuclear power pump and valve products with independent intellectual property rights and import and localization have occupied a certain proportion of market in China. Nuclear power technology, nuclear power equipment, and nuclear power pump valve products are also gradually in line with international standards. China's nuclear power industry is in a period of rapid development, Qinshan nuclear power plant is located in — &mdash “ Haiyan County of Zhejiang province; Chinese nuclear ” before the formal foundation, build by the government and the nuclear group cooperation in Zhejiang province. In 2013, the Zhejiang provincial government officially issued the "Chinese nuclear city planning", the plan put forward in 2015, Chinese city to achieve nuclear power nuclear power service industry output value of 10 billion yuan, nuclear power equipment manufacturing industry output value of 5 billion yuan, and strive to 2015 nuclear power related industry output value reached 50 billion yuan target.
According to the relevant analysis, by 2020 China's nuclear power installed capacity will exceed 70 million kilowatts, accounted for 6% share of China's power, which means that at least the construction of 60 1 million kilowatt nuclear power stations need to direct investment will be more than 500 billion yuan, which provides opportunities and a broader market for nuclear power valve Chinese enterprises and related products (valves, pumps) space.
The reutilization of nuclear power has stimulated the market of pump and valve in China. Many enterprises have seen the huge profits of nuclear power, especially the demand for pump and valve products, showing a trend of rapid growth. Many enterprises have seen the value of nuclear power. Valve products has a great impact on the role of nuclear power in nuclear power industry also has a circle on its own, domestic enterprises need spotted this market trend.
Low domestic share of nuclear power pump valve
Because of the particularity of nuclear power plants, the requirements of nuclear power valves are different from ordinary valves, which not only need good performance and high reliability, but also need strict quality assurance in design and manufacturing process, which belongs to high-end products of valves. In the field of nuclear power supply, only a few enterprises can supply the pump and valve products, and most of them depend on the import.
At present, the localization rate of nuclear valves is only 4% in China's running nuclear power plants. It is known that 14 nuclear power plants are in operation in China and 27 nuclear power plants are being built. As the nuclear grade pump of the third generation AP1000 nuclear power plant, the 4 AP1000 nuclear power plant units used in China are all imported.
At present, the quality problems of nuclear power pump valves and supporting products are shocking. Compared with foreign nuclear power countries, China's nuclear power technology level and equipment manufacturing capacity are relatively backward, and there is a bottleneck. The main manifestation of the core technology with independent intellectual property rights in the absence of the NSSS has no integrated supply capacity, like GE, that AREVA group.
