[The world's first industrial-scale high-temperature gas-cooled reactor with pebble bed module achieves initial full-power operation of dual reactors for the first time]

On December 9, the No. 1 and No. 2 reactors of Huaneng Shidaowan High Temperature Gas-Cooled Reactor Demonstration Project, a major national science and technology project, reached their initial full power, realizing stable operation under the mode of "two reactors with one turbine".

Initial full power refers to the current reactor core with mixed fuel loaded reaches the rated operating power, this operating state has verified that all systems of the demonstration project meet its design functions, laying the foundation for future commercial operation.

It is understood that the Huaneng Shidaowan high-temperature gas-cooled reactor demonstration project is the world's first pebble bed modular high-temperature gas-cooled reactor, and it is also a fourth-generation nuclear power project with independent intellectual property rights. China Huaneng cooperated with Tsinghua University and China National Nuclear Corporation to carry out scientific and technological research, achieved the initial full-power operation target of the dual reactors, and tested the operation control capability of the high-temperature gas-cooled reactor in the "two reactors with one turbine" mode, laying the foundation for future commercial operation.

I hope China standardizes its nuclear reactors in the next 30 years. Right now it's operating too many types of reactors.

- VVER
- AP1000
- EPR
- CANDU
- CAP1400
- CPR/ACPR

Too many designs complicate maintenance and logistics.

HEFEI -- The experimental advanced superconducting tokamak (EAST), or the Chinese "artificial sun", has achieved a continuous high-temperature plasma operation for 1,056 seconds in the latest experiment on Thursday, the longest time of operation of its kind in the world.

The breakthrough was announced on Friday by Gong Xianzu, a researcher at the Institute of Plasma Physics of the Chinese Academy of Sciences (ASIPP), who is in charge of the experiment conducted in Hefei, capital of east China's Anhui Province.

"We achieved a plasma temperature of 120 million degrees Celsius for 101 seconds in an experiment in the first half of 2021. This time, steady-state plasma operation was sustained for 1,056 seconds at a temperature close to 70 million degrees Celsius, laying a solid scientific and experimental foundation toward the running of a fusion reactor," said Gong.

The ultimate goal of EAST, located at ASIPP in Hefei, is to create nuclear fusion like the Sun, using deuterium abound in the sea to provide a steady stream of clean energy.

As opposed to fossil fuels such as coal, oil, and natural gas, which are in danger of being exhausted and pose a threat to the environment, raw materials required for the "artificial sun" are almost unlimited on earth. Therefore, fusion energy is considered the ideal "ultimate energy" for the future of humanity.

[The design of the high-flux research reactor of the Institute of Atomic Energy has made staged progress]

Recently, the design plan of the Institute of Atomic Energy's sodium-cooled fast neutron high-flux research reactor passed expert review, and determined the design power level of the research reactor, the level of neutron flux, the temperature of the core inlet and outlet, and the circuit type of the passive way to discharge the waste heat of the core. This marks a staged progress in the design of the research reactor, and will promote the implementation of my country's new fast neutron high-flux research reactor project, optimize the layout of nuclear basic scientific research facilities, and promote the high-quality development of the nuclear industry.

The fast neutron high-flux research reactor has a wide range of uses, and can carry out irradiation tests in various coolant forms such as sodium-cooled transient, lead/lead-bismuth, gas, molten salt, lithium, etc., and can also meet nuclear fuel cycle tests, isotope production, Nuclear basic research and other needs. With the continuous advancement of foreign new-generation fast neutron high-flux research reactors VTR (U.S. Multipurpose Test Reactor) and MBIR (Russian Multipurpose Research Reactor) projects, the construction of my country's fast neutron high-flux research reactors will be accelerated, and nuclear reactors will be improved. Basic innovation research capabilities have become an urgent need for the development of my country's nuclear capabilities.
