The Major National Science and Technology Infrastructure Project
High Intensity heavy-ion Accelerator Facility
On January 18th, 2018, The National Development and Reform Commission approves feasibility study report on High Intensity Heavy-ion Accelerator Facility (HIAF) and China Initiative Accelerator Driven System (CiADS), major national scientific and technological infrastructure during the Period of the Twelfth Five-year Plan, which marks that the two installations have officially entered the design and construction stage.
Both HIAF and CiADS are undertaken and constructed by Institute of Modern Physics, Chinese Academy of Sciences as juridical entity in Huizhou, Guangdong Province. The construction area of HIAF is 33,120 square meters, with a total investment of 1.521 billion RMB, and the construction period is 7 years. The construction area of CiADS project is 42,550 square meters, with a total investment of 1.817 billion RMB, and the construction period is 6 years. The cooperation unit of HIAF is Peking University. The cooperation units of CiADS include China General Nuclear Power Corporation, China institute of atomic energy, Hefei Institutes of Physical Science, Chinese Academy of Sciences, Chinese Academy of Sciences Guangzhou Branch and so on forth.
HIAF will build a high intensity heavy-ion accelerator with international leading level. The accelerator has the ability of generating nuclide extremely far from stability, can provide the highest peak current low-energy heavy ion beams in the world, generates the highest energy of 4.25 GeV per nuclear of pulsed ion beam and has the highest accuracy of nucleus’s mass measuring spectrometer all over the world. It offers internationally advanced conditions for identifying new nuclides, expanding the nuclide chart and studying the structure and reaction mechanism of weakly bound nucleus, especially for accurately measuring the mass of short-life nuclide far from stability. HIAF mainly includes accelerator system, experiment terminal system and supporting facilities.
CiADS aims to build the first transmutation research facility, driven by megawatt accelerator, to achieve high-power coupling running. The thermal power of its full superconducting accelerator driving system is 10 megawatts, including about 2.5 megawatts of beam power and about 7.5 megawatts of subcritical reactor core and blanket, which can run more than 24 at one time under full power condition. Through experimental verification and performance evaluation of key technologies, CiADS explores the technical route and process for safe and proper treatment and disposal of nuclear waste and provides condition to support China in taking the lead in mastering accelerator driven sub-critical system integration and nuclear waste transmutation technology. CiADS mainly involves superconducting linac, high power spallation target, subcritical reactor core and blanket, general control system and supporting facilities.
HIAF and CiADS have been strongly supported by Guangdong Provincial Government and People’s Government of Huizhou City. On December 1st, 2017, the feasibility study report of HIAF’s and CiADS’s supporting projects has been approved by Guangdong Provincial Development and Reform Commission. HIAF’s and CiADS’s supporting projects. The supporting projects possess a total land area of 726,700 square meters, a total construction area of 100,000 square meters and an estimated total investment of 2.354 billion RMB.
The construction of HIAF and CiADS, as part of the Guangdong-Hong Kong-Macao Greater Bay Area International Science and Technology Innovation Center, will provide technical and talent support for China's nuclear science basic research, advanced nuclear energy system of accelerator running and nuclear technology application.
