The third International Conference on Applications of Radiation Science and Technology (ICARST-2025), hosted by the International Atomic Energy Agency (IAEA), was held in Vienna, Austria from April 7 to 11. At the opening ceremony, IAEA Director-General Rafael Mariano Grossi highlighted the indispensable role of radiation technology in medical sterilization, food safety and environmental protection. He also emphasized the need to address barriers related to infrastructure, awareness and funding that limit the wider adoption of radiation technologies in many parts of the world.

As a leading Chinese enterprise in nuclear technology applications, China National Nuclear Corporation (CNNC) and its subsidiary China Isotope & Radiation Corporation (CIRC) formed the largest national delegation at the conference. They joined representatives from research institutions, enterprises and international organizations from more than 50 countries to explore new opportunities in nuclear technology applications. Leveraging its full industrial chain, CNNC has advanced the integration of Chinese solutions into the global nuclear governance. Through speeches, exhibitions and networking, the CIRC delegation showcased China's cutting-edge achievements in nuclear technology applications while reaffirming its commitment to international collaboration.

A side event titled "Radiation Technology for a Better Home", hosted by the China Atomic Energy Authority (CAEA) and co-organized by the China Isotope & Radiation Association (CIRA) and CIRC, attracted over 200 participants, including IAEA officials, global delegates and media. Five expert presentations delivered by Chinese researchers sparked wide interest and lively discussions.

During the keynote session, the Chinese research team delivered a standout performance, with 15 abstracts accepted for presentation. These covered the entire industry chain as well as cutting-edge research in nuclear technology application, showcasing China's strong academic presence and innovation in the field of radiation science and technology.

In the exhibition area, the China booth led by CNNC became a focal point of the event. With the theme "Atoms for a Better Home", CNNC set up core exhibition areas focused on nuclear medicine, radiation applications and security inspections. Through immersive design, physical exhibits and interactive experiences, the booth offered a panoramic view of China's innovative achievements as well as its global expansion in nuclear technology across the healthcare, industry and security sectors.

On the opening day of the conference, Najat Mokhtar, IAEA Deputy Director General and head of the Department of Nuclear Sciences and Applications, visited CNNC's booth. She engaged in in-depth discussions with the Chinese delegation on the latest advances in nuclear technology applications, expressing her high appreciation for CNNC's innovative practices and global reach in areas such as nuclear medicine and industrial irradiation.

China's nuclear technology application industry is growing rapidly, at a 15–20% rate annually. CNNC has established a diversified industrial layout spanning medicine, industry, agriculture and security, with its operations reaching over 30 countries and regions across the world.

Looking ahead, CNNC will continue to deepen its cooperation with the IAEA and other international partners to promote the inclusive application of nuclear technologies in areas such as cancer treatment and environmental protection. This will allow further contribution of Chinese expertise and strength to the global advancement of nuclear technology applications.
