Hefei now home to major science and technology facilities
By Zhang Rui
December 24, 2020

The city of Hefei in eastern China's Anhui province is now home to several national big science facilities, including a new grand research facility for fusion technology that is currently under construction.

China has made significant progress in magnetic confinement fusion over the past decade. With the successful operation of its nuclear fusion machine, the Experimental Advanced Superconducting Tokamak (EAST) since 2006 and headway in the International Thermonuclear Experimental Reactor (ITER) project, the country is achieving significant gains toward advanced steady-state operations and next steps in nuclear energy production.

The China Fusion Engineering Testing Reactor (CFETR), complementing the ITER facility, initially aims to achieve fusion energy production of up to 200 MW and eventually reach DEMO relevant power level which is over 1 GW. DEMO, short for the DEMOnstration power plant, will be the ITER's successor and bring fusion energy research to the threshold of prototype fusion reactor capabilities; the first step before the human race can build a true commercial nuclear fusion power plant.

Subsequently, the engineering design of CFETR, including the magnet system, vacuum system, tritium breeding blanket, diverter, remote handling, and maintenance system has been carried out within the CFETR national design team. Significant progress has been made but tremendous challenges remain, as outlined by a guide and staff member of the Hefei Institutes of Physical Science (HFIPS) during a tour by China.org.cn of the research facility's construction site.

The Comprehensive Research Facility for Fusion Technology (CRAF) is one of the country's biggest science facilities and a large scale R&D project for CFETR. Its objectives are to explore and master fusion DEMO-level key technologies; establish standard methodologies for manufacturing key material, components, and systems for CFETR; build key prototype systems and RAMI (Reliability, Availability, Maintainability, and Inspectability) for CFETR; test and validate the methods, technology, and systems for successful construction of CFETR; and train the next generation of fusion scientists, engineers, and managers.

CRAFT, led by the HFIPS under the Chinese Academy of Sciences (CAS), consists of 20 different facilities that address most of the key technologies and systems of CFETR. The construction of CRAFT started on Sep. 20, 2019, and will last for approximately five years and eight months with joint funds from the central and local governments. In addition, the construction of CRAFT's ancillary park began in early December 2018 and will be completed in August 2021.

The project is one of the country's major mega-science facilities and was listed in the country's 13th Five-Year Plan for science and technology development.

"We told people that we are building a 'man-made sun,' but that is just a vivid metaphor for the general public to understand what we are doing — scientists don't call it that. What we are actually creating is something that can forever resolve human's energy problem," the guide explained. However, he added, the construction of CFETR is a huge project, and still far from completion. In order to realize it, they disassembled the 19 key system problems in CFETR to study them separately. This research facility is now what is known as CRAFT.

Currently, there are more than 300 scientists and engineers working together on the CRAFT project. CRAFT will not only use the technologies from ITER but also those which will need to be developed in future and likely pose significant challenges and efforts. Once completed, it will become a comprehensive research platform in the field of fusion with DEMO-relevant technologies. It will also provide a useful facility for related fusion technology to be used industry-wide.

Together with CFETR engineering design and EAST experiments, CRAFT will provide a solid technical base for the successful construction of CFETR in the future. Upon completion of the facility, it will provide a technical foundation for the development and construction of the core components for fusion reactors. It will therefore be of great significance for ensuring the advancement, safety, and reliability of China's fusion reactors and will greatly accelerate the actual application of fusion energy in the country. It will also provide research platforms for cutting-edge, cross-disciplinary fields like energy, information, health, and the environment for China and the world.

The HFIPS, located on a peninsula near Shushan Lake in the western suburbs of Hefei, capital of Anhui province, was founded in 2001 and is a large-scale integrative research base within the CAS. It has 10 scientific research units, including the Anhui Institute of Optics and Fine Mechanics, the Institute of Plasma Physics, the Institute of Solid State Physics, and the Hefei Institute of Intelligent Machines. Research spans scientific fields such as energy, environment, biology, material, and information development, with a focus on research of and technology needed for magnetic confinement fusion, advanced nuclear energy and nuclear safety, atmospheric environmental monitoring and detecting technology, the science and technology of magnetic fields, the effects of extreme environments on advanced materials, robotic and intelligent devices, modern agricultural technology, medical physics, and high technology.

The HFIPS currently has over 2,700 employees, of which more than 2,000 are scientific researchers and technicians, including over 300 high-level talents. A further 2,000 are master's or doctoral students.

Hefei is now home to more than 20 well-equipped national, provincial, and CAS key laboratories or research centers as well as over 10 technical physics experimental platforms. These include other major science facilities, namely, the EAST tokamak device and auxiliary heating systems and the Steady High Magnet Field Facility. Through years of hard work, the HFIPS has become a China-based world leader in nuclear fusion research.

Hosting major science and technology facilities is part of the city's rise. In recent years, Hefei has excelled in scientific and technological innovation and talent attraction. In the latest Nature Index 2020 Science Cities ranking published in September, Hefei ranked 20th among global cities. Since 2017, Hefei has also ranked in the top six "Amazing China: Most Attractive Chinese Cities for Foreigners" — a survey conducted by the Information and Research Center of the Foreign Talents of the State Administration of Foreign Experts Affairs — for three consecutive years. The city is also home to numerous high-tech companies, including iFlytek and BOE Technology Group as well as China Speech Valley, the first national industrial park to focus on artificial intelligence and intelligent speech.

Limitless energy quest: Follow the sun

After thousands of nuclear fusion experiments, Chinese scientists made a big breakthrough on May 28 in their quest to create an artificial sun that could help solve the world's energy problems.

They set a record for sustained heat in nuclear plasma-a temperature of 120 million C for 101 seconds-said Gong Xianzu, a physicist in charge of the experiment in Hefei, Anhui province.

Gong, a leading researcher at the Institute of Plasma Physics in Hefei, said on Tuesday that the result at the Experimental Advanced Superconducting Tokamak, or EAST-nicknamed the "Chinese artificial sun"-also reached a temperature of 160 million C for 20 seconds.

A tokamak is a device that uses a powerful magnetic field to confine a nuclear reaction. It is one of several types of magnetic confinement devices being developed to produce controlled thermonuclear fusion power. The technology is said to be the leading candidate for a practical fusion reactor.

"The experiments try to simulate the nuclear fusion reaction that happens in the sun," said Gong, who joined the research 30 years ago.

Although the temperature at the core of the sun is relatively cool-about 15 million C-the density of plasma, which consists of ions and free electrons, is high enough to generate a sustained reaction.

In a fusion reaction, two or more atomic nuclei are combined to form one or more different atomic nuclei and subatomic particles. Theoretically, the process can produce massive amounts of clean, safe energy that could be manipulated in a nuclear reactor.

On Tuesday, scientists and engineers were continuing the experiment for the 99,145th time using the doughnut-shaped tokamak-which has a vacuum system, radio frequency wave system, laser scattering system and microwave system-a technical introduction that was explained, after they made the breakthrough at their 98,958th attempt on Friday.

Gong said the ultimate goal of the team's research is to create the necessary conditions for a fusion reactor.

"If we compare the tokamak facility to the engine of a car, then the reactor is akin to the vehicle as a whole," he said, adding that a vehicle is normally built for road tests before finally finding commercial use.

Ground was broken at the end of 2018 for construction of a fusion reactor-known as the Comprehensive Research Facility for Fusion Technology-in the outskirts of Hefei's Luyang district. The infrastructure is nearly complete, according to recent media reports.

The CRAFT website says construction will take five years and eight months.

"Challenges in the ongoing research come from two areas," Gong said. "We need to create the necessary conditions in which a fusion reaction can occur and meanwhile overcome a lot of engineering difficulties to make the reaction absolutely controllable."

He said the test reactor, which is still in the initial design phase, will use deuterium, a hydrogen isotope-a varied form of hydrogen with twice its atomic mass-that is abundant in the sea, to provide a steady stream of clean energy.
"We estimate that the deuterium in 1 liter of seawater can pro-duce through a fusion reaction the amount of energy produced by 300 liters of gasoline," he said.

Gong expressed hope that the reactor would be ready in the near future so he can personally witness it playing a major role in fulfilling China's commitment to achieving carbon neutrality before 2060. He said that in 2006 he witnessed the launch of the tokamak facility in Hefei, which was the first of its kind.

The fusion reactor will be an internationally open platform for scientists from around the world, according to the CRAFT website.
