Codes on the Safety of Nuclear Power Plants in Relation to Seismic Design Yuanjun Li 1, a 1College of Civil Engineering, Wuhan University, Wuhan, 430072, China aliyjwh@163.com Key words: Code of nuclear safety; Nuclear power plant siting; Seismic design; Capable fault Abstract.
About nuclear safety system 1.1 United States The United States advances the code of nuclear safety in the world, and the U.S. standards is widely referred by other countries.
The relevant standards were then developed by the American Society of Mechanical Engineers (ASME), Electrical and Electronics Engineers (IEEE) , American Society for Testing and Materials (ASTM) and American Nuclear Society (ANS).
And the ANS must comply with the provisions of the NRC regulations. 1.2 IAEA The IAEA serves as an intergovernmental forum for scientific and technical cooperation in the peaceful use of nuclear technology and nuclear power worldwide.

Introduction Materials and processing methods used in aeroengine, aerospace and engineering industries are constantly evolving.
Due to the unique mechanical, physical and chemical properties, such as high ductility, good weld ability, heat resistance and reduced cold brittleness, nickel-chromium alloy 10H11N23T3 MR-VD is used in aircraft engineering, but its use was limited because of the high cost of treatment due to poor workability.
