Abstract
Main Pipe is the aortic of nuclear power plant reactor coolant system.In a factory,tensile test results of ring welds of main pipe during the simulated weld do not meet RCC-M.Tensile test requirements and acceptance criteria about ring welds of main pipe are compared under different standards.The strict requirements of the regulatory principles were drawn.Then the establishment of standards of nuclear power is the key to the localization of nuclear power,and is the basis for standardization,series and regulation of nuclear power development.Construction of nuclear power needs to establish a set of the national, uniform and complete standards system for pressurized water reactor nuclear power plants in China.关键词
