Abstract: The localization of digital control system (DCS) in nuclear power plant is an important part of nuclear power independence strategy. In order to further improve its localization level, the localization substitution of components in the development process of DCS equipment is preliminarily studied. And the current situation of domestic components is analyzed. The difficulties faced in the localization of DCS components in nuclear power plants are summarized, such as the lack of component categories, high cost of quality control and lack of information. Based on the experience of components localization in the field of weapon equipment and aerospace, the general methods of component replacements are summarized. Then according to the NB/T 2001 standard, the automotive-grade components are proposed to use as an alternative solution. By implementing the strategy of grading screening, the balance between quality and cost can be realized. At last, it is proposed to strengthen the cooperation between research and application, which can provide a feasible scheme for the localization of components in DCS of nuclear power plant.

Key words: nuclear power plant; digital control system (DCS); electronic component; localization
