China's nuclear energy sector achieved a major technological milestone on Monday as China General Nuclear Power Group officially unveiled the 2.0 version of its proprietary Hualong One nuclear reactor design to the global market, a breakthrough experts say will significantly bolster the country's nuclear export competitiveness and high-end equipment manufacturing prowess.

The launch marks a vital step forward for the nation's independently developed nuclear technology, transitioning from domestic operational success to a world-class industrial benchmark, said industry experts.

Hualong One is China's third-generation nuclear power technology with full intellectual property rights. It is also one of the most widely accepted series of third-generation nuclear power reactors in the world.

"The upgraded reactor design not only cements China's self-reliance in cutting-edge nuclear engineering, but also dramatically elevates the commercial appeal of Chinese nuclear solutions in international tenders," said Lin Boqiang, head of the China Institute for Studies in Energy Policy at Xiamen University. "By driving down full lifecycle capital and maintenance costs while raising safety standards, it positions China as an increasingly indispensable partner in the global clean energy transition."
