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.

HEFEI Chinese scientists have set a new world record of achieving a plasma temperature of 120 million degrees Celsius for a period of 101 seconds in the latest experiment on Friday, a key step toward the test running of a fusion reactor.
Gas injection system | Last manifolds completed in China
Contractors to the Chinese Domestic Agency have completed an important part of the gas injection system the distribution manifolds that carry gas species from the tritium plant to the ITER machine and back for processing.
Members of ITER s Fuelling & Wall Conditioning Section inspect a batch of gas injection manifolds from China in June 2020. Manufacturing is now complete and the last batches will be shipped from China.Think of them as service pipes, with important added characteristics to meet ITER s strict regulations for protection-important components . Inside of a large guard pipe, six process lines for gas going toward the plasma surround a central evacuation pipe that transports exhaust gases back to the tritium plant. In the interspace is an inert gas (nitrogen) flowing toward tritium plant, where any leaks from the process pipes can be detected.

The first project of the Chinese Helium-Cooled Ceramic Breeder Test Blanket System (HCCB TBS) for the Iter fusion reactor project was launched on 15 March at China National Nuclear Corporation s (CNNC s) Southwestern Institute of Physics in Chengdu, Sichuan province. It marks the start of China s implementation phase of tritium breeding technology in Iter.

A tritium breeding blanket is a core component for future fusion reactors to realise tritium breeding self-sufficiency and electricity generation, CNNC said. The Iter Test Blanket Modules (TBMs) programme aims to carry out tritium breeding blanket technology verification in the real fusion reactor environment provided by ITER. The HCCB TBS system is a vital part of China s participation in the ITER programme.
