中国产核用富集硼酸将装入“华龙一号”

Core Insights - The successful delivery of domestically produced enriched boric acid to the Guangdong Lufeng Nuclear Power Unit 5 marks a significant breakthrough in China's nuclear material supply chain, indicating a move towards self-sufficiency in critical nuclear chemical materials [1][2] Group 1: Product Development - Enriched boric acid, produced through isotope separation technology, has its boron-10 abundance increased from natural levels of less than 20% to over 96%, playing a crucial role in nuclear safety by absorbing neutrons in pressurized water reactor cores [2] - The production of enriched boric acid has previously relied on imports due to complex production processes and stringent quality standards, raising supply chain security concerns as nuclear power construction scales up [2] Group 2: Research and Innovation - The Suzhou Thermal Research Institute, leading the domestic development project since 2022, collaborated with Shandong Heyi Gas Co., Ltd. and other chemical enterprises to innovate production processes and facilitate industrial transformation [2] - The research team overcame traditional production challenges, achieving over a 20% increase in boron isotope separation efficiency, reducing impurity content by more than 50%, and maintaining isotope abundance control deviation of less than 1%, with product quality reaching international advanced levels [2]
