Design analysis for AP1000 hydrogen piping system

The AP1000 nuclear power plant is the third generation nuclear power technology jointly developed by China and the United States. AP1000 nuclear power plant is designed by the Westinghouse consortium and constructed by the State Nuclear Power Technology Company which is responsible for the self- reliance supporting project through technology introduction. Due to the engineering particularity, the construction involves many Chinese and American standard matching and compatibility problems. Through comparing and analyzing material and test requirement in standards, connected with relevant problems of AP1000 hydrogen piping design, it hopes to provide reference for the hydrogen piping design in domestic nuclear power plant.
