As a high-tech strategic emerging industry that is a key focus of national cultivation, China's nuclear power industry has long adhered to safe and innovative development, and has initially formed new productive forces in practice; In the face of a new stage of development, the nuclear power industry needs to strengthen the drive of new quality productivity, actively build a modern industrial system, and promote high-quality development of nuclear power. This article is based on the analysis of the development trend of the nuclear power industry at home and abroad, and introduces the characteristics and foundation of the development of new productive forces that China's nuclear power industry has initially possessed. Based on the research results of the academic community on the theory of new quality productivity, it is proposed to actively leverage the doubling effect of new technologies and big data on productivity, and cultivate and develop new quality productivity in nuclear power. At the same time, we will deeply explore the essence of "innovation" in all elements of nuclear power, propose to promote the high-quality development of nuclear power through three practical paths: propose more original innovation, integrated innovation, and systematic innovation, promote the digital transformation of nuclear power and "giving birth to new industries, new models, and new driving forces".
