Abstract: As the third generation nuclear reactor in the world, the AP1000 reactor was introduced to China in 2006. Through ten years of efforts, it is basically realized to design and apply the AP1000 reactor to engineering as marked by the commissioning of the first reactor unit in 2016. Based on the national strategy of developing clean energy and manufacture industry in the 13th Five-Year Planning period (2016-2020), the paper systematically introduces the domestic manufacturing of the key equipment of AP1000 reactor unit, and analyzes the problems arising from the domestic manufacture and the direction of research, which will provide a support for perfecting the localized equipment supply chain of the AP1000 reactor units.

Key words: nuclear power, load following, safety, economy, feasibility
