On September 14 local time, the 70th session of the General Conference of the International Atomic Energy Agency (IAEA) opened in Vienna. In the presence of Shan Zhongde, Director of the National Atomic Energy Agency of China (CAEA), and Zhang Tao, Director General of the China National Nuclear Corporation (CNNC), Shi Qi, CEO of China Nuclear Energy Company (CHINERGY CO., LTD), and Rafael Mariano Grossi, Director General of the IAEA, officially signed the world’s first cooperation agreement on high-temperature gas-cooled reactors.
The signing of this agreement marked the expansion within the IAEA of capabilities in the field of high-temperature gas-cooled reactors from China on a global scale. It also signifies that Chinese advanced fourth-generation nuclear technology, relying on the multilateral cooperation platform of the IAEA, is moving from commercial demonstration to a new stage of global promotion.
China accelerates the industrialization of high-temperature gas-cooled reactors
The high-temperature gas-cooled reactor is an advanced fourth-generation nuclear technology independently developed by China. The intellectual property rights for this technology are fully owned by the PRC. This technology, characterized by high intrinsic safety, increased power generation efficiency, and a wide range of applications, can be widely used in areas such as power generation, heat production, steam generation, water desalination, hydrogen production, and more.
Deepening international cooperation — promoting the joint formation of global standards
This agreement is the first cooperation agreement signed by the IAEA in the field of high-temperature gas-cooled reactors. It reflects the high recognition by the international community of Chinese technology for high-temperature gas-cooled reactors and the potential for their industrialization, and also marks the transition of global cooperation in the field of high-temperature gas-cooled reactors from “experience sharing” to “joint standard setting,” which will provide important support for China’s further involvement in the development of international standards and regulations in the field of nuclear energy.
