Shenzhen: China's Gen-III+ advanced nuclear power technology, "Hualong One" 2.0, was unveiled at the CGN 2026 Sustainable Development Conference in Shenzhen, attended by more than 200 representatives from 28 countries and regions.

According to BERNAMA News Agency, the technology builds on the existing defence-in-depth (DiD) safety architecture and optimises 14 safety features, with improvements in nine key safety indicators. The technology allows operators to remain without intervention for 72 hours post-accident and enables a seven-day accident self-sustaining capability.

The unveiling highlighted the simplification of auxiliary system configurations, reducing pipeline length by approximately 31 per cent, process valves by about 25 per cent, nuclear island building volume by 21 per cent, and nuclear island installation volume by around 33 per cent. Additionally, the unit automation operation ratio is increased by 66 per cent, providing more precise system regulation and faster response, while key equipment features complete localisation capability.

Previously, CGN launched "Hualong One", China's Gen-III nuclear power technology with independent intellectual property rights. Currently, 10 "Hualong One" units are in commercial operation both domestically and internationally. Building on this foundation, the "Hualong One" research and development team, in collaboration with industry partners, has completed nearly 100 design optimisations and iteratively developed "Hualong One" 2.0.

On July 31, the State Council Executive Meeting approved eight nuclear power units, designating Phase III of the Guangdong Taipingling Nuclear Power Plant of CGN as a demonstration project for "Hualong One" 2.0.
