Core Viewpoint - The article discusses the critical role of nuclear fusion power systems in achieving stable and controlled nuclear fusion, likening it to a "heart" and "brain" of a fusion reactor, essential for maintaining the high-temperature plasma necessary for fusion reactions [4][5][6]. Summary by Sections Nuclear Fusion Power System - The nuclear fusion power system is a specialized high-performance power source that precisely controls the plasma in fusion reactions, which can reach temperatures exceeding 100 million degrees Celsius [5][6]. - Successful ignition of nuclear fusion requires three key conditions: high temperature, high density, and long energy confinement time, collectively referred to as the "fusion triple product" [6]. Types of Power Sources - There are two main types of nuclear fusion power sources: magnetic power sources and heating power sources [7]. - Magnetic power sources generate strong magnetic fields to suspend the high-temperature plasma, while heating power sources raise the plasma temperature to the required levels [7][10]. Performance Requirements - The power systems must meet stringent performance criteria, including voltage fluctuation control within 3%, response times under 0.3 milliseconds, and strong interference resistance [8]. Market Potential - The market for nuclear fusion power systems is projected to exceed 5 billion, based on current investment in fusion projects, with costs for fusion reactors ranging from 3 to 10 billion for a 1000MW scale [12][16]. - The domestic market is expected to grow further with the development of various fusion projects, including BEST, STAR, and others, with significant investments planned [13][14]. Industry Challenges and Opportunities - The nuclear fusion power sector faces challenges such as high operational demands on heating power sources and the need for advanced electronic components [16]. - The industry is still in its early stages, with a focus on technological advancements and the establishment of supply chains for specialized power systems [17]. Key Companies - The article identifies several key companies involved in the nuclear fusion power sector, highlighting their roles in the development and supply of necessary technologies and components [18].
