The world's first tunnel boring machine for high slope spiral tunnel construction developed by China rolled off the production line recently in Changsha, central China's Hunan. The machine will serve the construction of an underground laboratory in the vast Gobi desert.
 
 

China’s top weapons scientist says nuclear fusion power is 6 years away​

  • Peng Xianjue unveils plans for combined fusion-fission reactor that could make China world’s first to achieve the elusive viable energy source
  • No country has so far managed to build a facility that generates more power than it uses in the fission process

The academician has talk about this plan since years ago. What the article could confirm is that the z-pinch experimental device is in the current five year plan and expected to be completed in 2025.

[Aiming at the ultimate dream of the "artificial sun", China HL-2M completed and put into operation [Applause]]

December 4th, a new generation of advanced magnetic confinement nuclear fusion experimental device independently designed and constructed by China —— China Tokamak-2M (HL-2M), realized its first plasma discharge and officially put into operation at China National Nuclear Corporation's Southwest Institute of Physics.

HL-2M uses advanced structure and control method and is a large scale, advance parameters tokamak device in China. The plasma current capability has been increased from 1 megaampere of existing domestic devices to more than 2.5 megaamperes. Liu Yong, head of the China HL-2M project said, "HL-2M plasma ion temperature can reach 150 million degrees Celsius, it can achieve high-density, high-specific pressure, and high-bootstrap current operation, which will greatly enhance the level of China's core-level plasma physics research and related key technology research and development. It will provide important technical support for both China participation in ITER project and also China independent design and construction of fusion reactors. "
(Li Di Science and Technology Daily reporter Shengli)

The HL-2M Tokamak, China's new-generation "artificial sun," achieved a record-high plasma discharge of 1 million amperes on Wednesday, marking the country's breakthrough in the operation of controlled nuclear fusion device and a step towards fusion ignition.

Recently, the mechanical test loop device of the Institute of Atomic Energy for high-temperature dynamic lead-bismuth environment has successfully completed the debugging, and has the ability to carry out the mechanical performance test of the lead-bismuth reactor structural material, which marks that the Institute of Atomic Energy has taken the lead in mastering the lead-bismuth reactor materials and components used in lead-bismuth reactor. The key technology of mechanical performance testing in the environment provides important data support for the research and development of lead-bismuth reactor.

Lead-bismuth cooled fast reactor is one of the most promising reactor types among the candidate reactors of the fourth-generation nuclear energy system. It can be applied to offshore oil exploitation, island development, power supply for big data centers, energy supply in remote areas, and special nuclear power application.

【一体化快堆研发项目取得阶段性成果】近日,原子能院一体化闭式循环快堆核能系统(简称一体化快堆)研发项目顺利通过中国核电组织的首次专项检查。原子能院作为一体化快堆研发项目实施主体,对技术负总责;中国核电作为业主,对项目实施过程进行监督检查。此次专项检查通过,标志着项目关键点和重要控制点已按期完成,取得阶段性研发成果,并检验了承研单位和项目团队的组织实施与管理水平,为全面深入展开项目关键技术攻关奠定了基础、提供了保障。​
一体化快堆,指在同一厂址建设钠冷快堆、干法处理厂、燃料制造厂和废物处理设施,实现高效闭式燃料循环。一体化快堆也能够与当前压水堆有效衔接,利用压水堆乏燃料后处理回收的材料,以及天然铀中的铀-238为燃料运行,实现对铀资源的高效利用,并通过堆内燃烧方式大规模减少长寿命高放废物,从而提升核裂变能的整体安全性和经济性。一体化快堆是我国核能发展“三步走”战略——“热堆—快堆—聚变堆”第二步的高级阶段和必然选择,具有极其重要的战略意义。​

[Integrated fast reactor research and development project has achieved phased results]

Recently, the research and development project of the Institute of Atomic Energy's integrated closed-cycle fast reactor nuclear energy system (referred to as integrated fast reactor) successfully passed the first special inspection by the China Nuclear Power Organization. As the main body of the implementation of the integrated fast reactor research and development project, the Institute of Atomic Energy takes overall responsibility for the technology; China Nuclear Power, as the owner, supervises and inspects the project implementation process. The passing of this special inspection marks that the key points and important control points of the project have been completed on schedule, and phased research and development results have been achieved, and the organization, implementation and management level of the research unit and the project team have been tested, laying the foundation and support for the comprehensive and in-depth development of key technology for the project.

Integrated fast reactor refers to the construction of sodium-cooled fast reactor, dry processing plant, fuel manufacturing plant and waste treatment facilities on the same site to realize an efficient closed fuel cycle. The integrated fast reactor can also be effectively connected with the current pressurized water reactor, using the materials recovered from the reprocessing of the spent fuel of the pressurized water reactor, and uranium-238 in natural uranium as fuel to achieve efficient use of uranium resources. And through in-reactor burning of long-lived actinides radioactive waste is reduced on a large scale, thereby improving the overall safety and economy of nuclear fission technology. The integrated fast reactor is part of the "three-step" (thermal reactor-fast reactor-fusion reactor) strategy of China's nuclear energy development. It is the advanced and mandatory stage of the second step and has very important strategic significance.
