    Media reporters learned from a press conference held by China's Ministry of Science and Technology in Beijing on August 31 that a number of landmark achievements
    have been achieved in the past 10 years since the implementation of major national science and technology projects for large-scale advanced pressurized water reactors and high-temperature gas-cooled reactors.
    The major nuclear power project is one of the 16 national major science and technology projects determined in the Outline of the National Medium and Long-term Science and Technology Development Plan (2006-2020), mainly including large-scale advanced pressurized water reactor nuclear power plants and high-temperature gas-cooled reactor nuclear power plants
    .

    Up to now, 179 major nuclear power projects have been approved, and 54 acceptance projects have been completed
    .
    The experts drew four concrete results
    .

    First of all, the special key tasks of nuclear power have been smoothly advanced
    .
    The introduction of AP1000, digestion and absorption has been basically completed, and the main body of the hot test of the first unit of Zhejiang Sanmen relying on the project has been completed, and the loading is imminent
    .
    The design of CAP1400 passed the review, all key tests were completed, and the conditions
    for starting construction were met.
    Most of the main equipment of the high-temperature gas-cooled reactor has been installed in place and is about to enter the commissioning phase
    .

    Secondly, the equipment manufacturing capacity and level have been greatly improved
    .
    A number of major equipment such as pressure vessels, steam generators, and main pipelines have been localized, core equipment such as shielded motor main pumps, digital instrument control systems, and burst valves have been manufactured, and high-temperature reactor control rod drive mechanisms, fuel loading and unloading systems, etc.
    have been supplied
    .

    According to reports, China has an annual output of 6 to 8 sets of third-generation nuclear power equipment supply capacity, and the comprehensive localization rate of third-generation nuclear power has increased from 30% in 2008 to more than
    85%.

    The third is to achieve a fundamental breakthrough
    in material development.
    The processing and manufacturing technology of key materials such as super-large forgings, 690 alloy pipes, pressure vessel seals, and nuclear-grade zirconium has made qualitative breakthroughs
    .
    High-temperature reactor fuel elements have been industrialized
    .
    The first complete production line from sponge zirconium to finished tubes, plates, rods and strips was built, providing strong support
    for the independent fuel research and development of CAP1400 and Hualong No.
    1.

    "At least two or three manufacturing plants for each type of critical equipment have processing capabilities, creating a good competitive atmosphere
    .
    " Zheng Mingguang, president of the Shanghai Nuclear Engineering Research and Design Institute, said
    .

    Finally, the foundation
    of R&D has been consolidated.
    Nuclear power enterprises and research institutes jointly carried out in-depth analysis of common technologies such as key technologies for reactor core and safety analysis, serious accident mechanism and phenomenology, and the performance of key materials in nuclear power plants, and built 51 new and renovated 12 internationally leading large-scale benches and test facilities, accumulating massive data, and providing guarantee for China's new nuclear motor design and continuous improvement of nuclear power innovation and research and development capabilities
