Abstract: Nowadays the development of nuclear power industry in China is just at its peak,which make it imperative to get the production of nuclear power equipment and related manufacture material localized. Relevant practice shows that great progress has been made in the said production localization process. Elaborated are the quality requirements for seamless steel tubular products as used for nuclear power plant construction and manufacture of nuclear power equipment;analyzed are the achievements made in the process of localization of nuclear power-purposed seamless steel tubes and pipes,and the main problems as existing in the field;and put forward are the suggestions for further speeding up the said localization process.
