中国自主研发核用富集硼酸实现核电机组规模化供货

Core Points - The China General Nuclear Power Group's Suzhou Thermal Engineering Institute has successfully delivered domestically developed enriched boric acid to the Guangdong Lufeng Nuclear Power Unit 5, marking a significant step in achieving a self-controlled supply chain for this critical nuclear material [1] - Enriched boric acid, which is essential for the safe operation of nuclear power plants, has previously been reliant on imports due to complex production processes and stringent quality standards [1] - The successful delivery of enriched boric acid indicates China's capability to ensure stable supply, reliable quality, and reasonable pricing in the enriched boric acid sector, thereby enhancing supply chain security for the country's nuclear power development [1] Industry Summary - The enriched boric acid is produced by increasing the abundance of boron-10 from less than 20% in natural sources to over 96% through isotope separation technology [1] - The Suzhou Thermal Engineering Institute initiated the domestic research and development project for enriched boric acid in 2022, collaborating with various domestic chemical enterprises to innovate processes and facilitate industrial transformation [1] - The research team overcame challenges related to traditional production methods, achieving over a 20% increase in isotope separation efficiency and reducing impurity content by more than 50%, with product quality reaching international advanced levels [1]
