Core Viewpoint - The nuclear power digital control system (DCS) is crucial for the safe operation of nuclear power plants, transitioning from reliance on foreign technology to achieving self-sufficiency and independence in technology development [1][10]. Industry Overview - The DCS is the "nerve center" of nuclear power plants, responsible for monitoring, controlling, and protecting reactor and plant key equipment [1][10]. - The DCS consists of safety-grade and non-safety-grade systems, ensuring both safety and efficient operation of nuclear power plants [1][10]. Industry Development History - China's DCS industry began in 2004, with significant milestones including the development of the "Harmonious System" in 2010 and the first application of the "Longfin" system in 2018 [4][5][10]. - By 2023, China had become the fifth country globally to master nuclear-grade DCS technology, marking a significant shift towards self-reliance [5][10]. Market Size and Growth - The market size for China's nuclear DCS has grown from 1.43 billion yuan in 2016 to an estimated 3.096 billion yuan in 2024, with a compound annual growth rate (CAGR) of 10.13% [1][11]. - The number of operational nuclear power units in mainland China is projected to increase from 37 in 2017 to 58 by 2024, with installed capacity rising from 35.81 million kW to 60.88 million kW, reflecting a CAGR of 7.88% [8][9]. Industry Chain - The DCS industry chain includes upstream suppliers of materials and components, midstream developers and integrators, and downstream applications primarily in nuclear power plants [6][10]. Key Enterprises - Leading companies in the DCS sector include China Nuclear Control, Beijing Guoli Nuclear, and several others, which are actively working to break the foreign monopoly and promote domestic DCS development [2][3][11]. - Beijing Guoli Nuclear has developed the "Harmonious System," which has been applied in multiple domestic nuclear projects, enhancing the safety and stability of operations [12]. Future Trends - The DCS industry is expected to evolve towards greater integration of artificial intelligence, enhanced cybersecurity, and improved autonomous decision-making capabilities [1][13]. - Focus areas for future development include achieving full autonomy in core technologies, establishing a complete domestic supply chain, and ensuring the safety and reliability of systems [14][15].
