China's nuclear power development has been more than 20 years, before 2008, China's nuclear power containment prestressed construction all adopt foreign prestressed anchorage system. After years of efforts, Liuzhou Overwem Machinery Co., Ltd. has developed the second generation of improved prestressed anchorage system for nuclear power and the third generation of prestressed anchorage system for nuclear power, and has developed supporting construction equipment to realize the localization of China's nuclear power prestressed anchorage system. In this paper, the domestic prestressed anchorage system for nuclear power and the key and difficult points in the field construction of prestressed nuclear power are introduced.
