"人造太阳"并不是简单的复制天上的真实太阳，而是复制核聚变反应过程的装置，因此"人造太阳"的全称叫"聚变堆主机关键系统综合研究设施"。 "人造太阳"怎么建设？它又长什么样？一起来听总台记者刘军在现场的介绍。 "人造太阳"究竟是什么 ? 在合肥滨湖科学城，一颗"人造太阳"正在建设当中。 重活细活都能干 "人造太阳"有了"检修工" 在现场，记者发现在"橘子瓣"的上中下三个位置都留有窗口，它们用于安装各种系统设备和内部部件的调试及维护。但这些窗口并不是供人进出，而是机械 臂的进出通道。 在"橘子瓣"的旁边，有一个蓝色的大机械臂，它就是远程维护的主力军，叫"多功能重载机械臂"。它的重量有16吨，不仅能抓取重达几吨的零部件，还能 对"人造太阳"的核心部件进行拆装、切割、焊接、打磨等一系列精细操作，精度误差在5毫米以内。用科研人员的话来说，就是"身强力壮能绣花，重活细活 都能干"。 记者所处的位置是安徽合肥大科学装置集中区的一栋厂房里。在他身旁的高耸装置，就是下一代"人造太阳"的核心部件"1/8真空室"。它重295吨，高19.5 米，看上去像一个巨大的"橘子瓣"。 "人造太阳"其实并不是简单复制天上真实的太阳，而是复制核 ...

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].

Core Viewpoint - The rapid development of major scientific infrastructure in China is highlighted, particularly in the field of fusion energy, with significant projects like "Kua Fu" and "EAST" aiming to advance clean energy solutions for the future [1][14][19]. Group 1: Major Scientific Facilities - The "LHAASO" facility, located at an altitude of 4,410 meters, is the world's highest and largest ultra-high-energy gamma-ray observatory, searching for elusive cosmic rays [3]. - The "FAST" telescope, with a diameter of 500 meters, extends humanity's view into the universe, reaching distances of up to 10 billion light-years [5]. - The Jiangmen Neutrino Experiment, situated 700 meters underground, utilizes a liquid scintillator detector to amplify weak signals by 10 million times to capture neutrinos, known as "ghost particles" [7]. Group 2: Fusion Energy Development - The "Kua Fu" project is designed to simulate the nuclear fusion reactions occurring in the sun, aiming to develop fusion energy as a clean and virtually limitless power source [8][11]. - Fusion energy is characterized by its abundant raw materials, safety, efficiency, and low carbon emissions, presenting a potential solution to humanity's energy challenges [9]. - The "Kua Fu" facility in Hefei is currently under construction and is expected to be fully operational by the end of 2025, providing a comprehensive research and testing platform for future fusion reactors [13][14]. Group 3: Research Progress and Achievements - The "Kua Fu" project has reached a critical phase, with various subsystems undergoing integration and testing, including the development of a toroidal field coil to generate strong magnetic fields for plasma confinement [24]. - The "EAST" facility has achieved a world record by maintaining a high-confinement plasma state at 100 million degrees Celsius for 1,066 seconds, marking a significant breakthrough in fusion research [21]. - The BEST project, a compact fusion energy experimental device, has commenced construction, aiming to simulate the operational conditions of future commercial fusion reactors [22]. Group 4: Future Outlook - The current research focuses on foundational experiments and engineering technology validation, with expectations for demonstration of fusion power generation within the next decade and commercial viability in 20 to 30 years [25].
