China's Nuclear Power Technology: The world's first large-scale production line for fuel elements in high-temperature gas-cooled reactors

On July 17, Wang Shoujun, Chairman and Secretary of the Party Group of CNNC, announced at the promotion meeting of the world's first high-temperature gas-cooled reactor fuel element production line for major national science and technology special supporting projects held in Baotou that the 200,000th spherical fuel element of the world's first industrial-scale high-temperature gas-cooled reactor fuel element production line was successfully rolled off the production line
in Baotou.

Wang Shoujun said that the official launch of the 200,000th spherical fuel element is an important milestone in the demonstration project of large-scale advanced pressurized water reactor and high-temperature gas-cooled reactor of major national science and technology, marking that China's high-temperature gas-cooled reactor component manufacturing level has been in the forefront of the world, which is of great significance
for promoting the commercialization of high-temperature gas-cooled reactor nuclear power technology and "going global".

It is reported that high-temperature gas-cooled reactors are internationally regarded as the priority research and development objects
of the fourth-generation nuclear energy system because of their inherent safety and versatility in the development and utilization of high-temperature thermal energy.
Compared with other reactor types, China is one of the few countries
in the world that has mastered the technology of high-temperature gas-cooled reactors and is at the forefront.

The reason why the high-temperature gas-cooled reactor is called a reactor type with relatively high inherent safety in the world is mainly because the fuel element used is coated with particles that can withstand high temperature, and graphite as a moderator, core structure material and reflective layer material has high high temperature resistance characteristics
.

Wang Shoujun pointed out in his speech that the inherent safety, multi-purpose and modular construction characteristics and advantages of high-temperature gas-cooled reactors are especially suitable for small and medium-sized power grid countries under the "Belt and Road", and have multiple advantages
in nuclear power going global.
At present, China has signed a memorandum of understanding on cooperation in high-temperature gas-cooled reactor projects with Saudi Arabia, the United Arab Emirates and other countries and regions, indicating that China's high-temperature gas-cooled reactor has ushered in a historic development opportunity
after decades of silent cultivation.

He said that on the basis of the existing achievements, it is necessary to continue to implement the national "Belt and Road" and nuclear power going global strategy, meet the international and domestic commercialization needs of high-temperature gas-cooled reactors, accelerate the commercialization and large-scale process of high-temperature gas-cooled reactor components, and make new contributions
to realizing the strategy of nuclear power going global and building a nuclear power power.
