China's Hualong One nuclear reactor design has emerged as the world's most widely deployed third-generation nuclear technology, with 41 operational or under-construction units globally, according to the China General Nuclear Power Group (CGN). The announcement, made during a press briefing in Shenzhen, highlights China's growing influence in clean energy innovation.
Each Hualong One unit generates over 10 billion kilowatt-hours of electricity annually – sufficient to power one million residents in a moderately developed nation while cutting carbon emissions by 8.16 million tonnes. Seven units are already connected to power grids worldwide, demonstrating what CGN describes as 'exemplary operational performance.'
Developed through fully independent research, the technology meets stringent international safety standards, including European Utility Requirements certification and UK Generic Design Assessment approval. This homegrown solution forms a cornerstone of China's decarbonization strategy, offering a blueprint for sustainable energy transitions.
International collaboration continues to expand, with China National Nuclear Corporation (CNNC) confirming cooperation agreements across more than 20 countries and regions. Pakistan's Karachi-2 and Karachi-3 reactors – the first overseas Hualong One projects – have already produced 48 billion kilowatt-hours of electricity, reducing annual coal consumption by 14.97 million tonnes and carbon emissions by 39.16 million tonnes.
'These projects demonstrate how technological innovation can drive both energy security and climate action,' a CNNC representative stated, emphasizing the reactors' role in supporting Pakistan's sustainable development goals.
