The Fukushima Daiichi nuclear disaster has rekindled the world's attention to nuclear safety following the devastating nuclear accidents that occurred in the Three Mile Island and Chernobyl. As China continues to expand in nuclear power development, how it views and responds to nuclear safety carries significant implications on its nuclear safety and security in the future. This paper examines the Chinese authorities' response to nuclear safety pre- and post-Fukushima, based on (1) a longitudinal big-data discourse analysis of the Chinese newspaper articles published during the period 2008–2017, and (2) an in-depth comprehensive review of nuclear safety performance and safety governance based on credential and publicly available documents and websites, both locally and internationally. Our assessment reveals that (i) China's concerns over nuclear safety and accident surged immediately following the Fukushima crisis. Increasing attention towards nuclear emergency response has been observed since 2014, (ii) China has displayed strengths in reactor design and safety operation, and (iii) its safety governance has been constrained by institutional fragmentation, inadequate transparency, inadequate safety professionals, lack of a strong safety culture, amid its ongoing plans to increase nuclear capacity three-fold by 2050. To improve nuclear safety, China may further strengthen its safety standards, safety management and monitoring, improve institutional arrangements, increase the ratio of safety professionals, intensify its safety culture and transparency, develop process-based safety regulations, and champion international collaboration to keep itself abreast of the latest international best practices. • China's concerns over nuclear safety surged after the Fukushima crisis. • China displayed strengths in reactor technology design and safety operation. • China can benefit from better safety management culture, institutional integration and and and regulatory design, etc. [ABSTRACT FROM AUTHOR]
