Core Viewpoint - The successful development of China's first 10,000-watt helium refrigerator marks a significant breakthrough in ultra-large helium low-temperature refrigeration technology, which will support major scientific infrastructure and clean energy solutions [1][2]. Group 1: Technology and Innovation - The helium refrigerator has a liquefaction rate of 3,370 liters per hour, which will be utilized in the accelerator-driven transmutation research facility for nuclear waste processing [1]. - The refrigerator operates at liquid helium temperatures (minus 269 degrees Celsius) and is essential for cutting-edge research in large scientific installations such as accelerators and controlled nuclear fusion [1]. - All core components of the refrigerator, including the helium gas compressor and the ultra-large high-vacuum insulated cold box, are independently developed by China [2]. Group 2: Specifications and Features - The ultra-large high-vacuum insulated cold box measures approximately 28 meters in length, over 4 meters in diameter, and weighs 180 tons [2]. - The helium gas bearing turbine expander can achieve speeds of 100,000 to 150,000 revolutions per minute under heavy load and high power conditions [2]. Group 3: Applications and Impact - The helium refrigeration technology is expected to provide critical support for basic scientific research, medical device development, and rare gas separation, while also addressing challenges in the storage and transportation of large-scale clean energy [1]. - The development of this technology is anticipated to promote the sustainable development of the new energy industry [1].
