Nuclear power valve in 2013 or the peak of development

Nuclear power is recognized as clean energy in the world, and along with the development of nuclear power technology, the safety and economy of nuclear power have been improved. China has also increased investment in nuclear power. The development strategy of nuclear power has been adjusted from “appropriate development” to “active development.” With the rapid development of the nuclear power industry, the demand for nuclear power valves will continue to expand.

Domestic nuclear power construction accelerated in 2009 and stagnated after the 2011 Fukushima nuclear accident in Japan. Nuclear power is currently the only clean energy that can replace fossil fuels on a large scale and has strong market competitiveness. The proportion of domestic nuclear power generation is about 1.8%, and the global average is 14%. The 2020 target set by the National Development and Reform Commission’s "Mid-term and long-term development plan for nuclear power (2005-2020)" in October 2007: By 2020, the installed capacity of nuclear power is expected to reach 40 million kilowatts; at the same time, considering the subsequent development of nuclear power, by the end of 2020, Nuclear power capacity should be maintained at about 18 million kilowatts. From 2007 to 2010, China started 4, 4 units, 6 units and 4 units respectively. After the nuclear accident in Fukushima, Japan on March 11, 2011, the nuclear power industry in the world agreed that the third-generation AP1000 nuclear power technology that can solve nuclear safety issues such as emergency core cooling without relying on external power supplies Advanced.

On March 16, 2011, Premier Wen Jiabao of the State Council presided over a State Council Executive Meeting to listen to reports on the situation concerning nuclear leakage from the nuclear power plant in Fukushima, Japan, and made four decisions: (1) Immediately organize a comprehensive safety inspection of China's nuclear facilities; (2) ) Effectively strengthen the safety management of operational nuclear facilities; (3) Comprehensively review nuclear power plants under construction; (d) Strictly approve new nuclear power projects.

The total installed capacity of currently operating and under construction nuclear power plants in China is approximately 44 million, which fully meets the original target of 40 million kilowatts of installed nuclear power installed capacity by 2020; as no third-generation AP1000 units have global operating precedents, nuclear power technology has not been fully verified. We judge that the scale of domestic nuclear power construction during the “12th Five-year Plan” period will be strictly controlled.

On May 31, 2012, Premier Wen Jiabao of the State Council presided over the executive meeting of the State Council to hear again about the comprehensive safety inspections of civilian nuclear facilities across the country. The “12th Five-Year Plan” for nuclear safety and radioactive pollution prevention and control and the long-term vision for 2020 were discussed and approved in principle. 》: At present, China has 15 nuclear power generating units, with a total installed capacity of 12.44 million and 29 under construction (including four million kilowatts of passive pressure water imported from the Westinghouse Company in the United States, including Sanmen, Zhejiang, and Haiyang, Shandong. The reactor AP1000 unit) has a total installed capacity of 31.6 million kilowatts (including 3 main projects not started).

Persist in the development of nuclear power under the premise of ensuring safety, and grasp the development rhythm; before the nuclear power technology that complies with the most advanced safety indicators is fully verified, reasonably control the scale and speed of nuclear power construction; actively develop safe performance with China’s independent intellectual property rights Advanced nuclear power technology.

On October 24, 2012, Premier Wen Jiabao chaired an executive meeting of the State Council to discuss the adoption of the “12th Five-Year Plan for Energy Development” and re-discussed and adopted “Nuclear Power Safety Planning (2011-2020)” and “Long-Term Development of Nuclear Power”. Planning (2011-2020) will deploy nuclear power construction for the current and future periods: (1) Safely restore normal construction, reasonably grasp the construction rhythm, and steadily advance in an orderly manner; (2) Science layout project, "Twelve Five Years In the period, only a few well-argued nuclear power project sites were arranged along the coast, and no inland nuclear power projects were arranged. (3) Improve access thresholds, build new nuclear power projects in accordance with the world's highest safety requirements, and build new nuclear power generating units must meet three generation safety standards.
