China National Nuclear Corporation Masters Boron-10 Isotope Separation Technology
TapTechNews October 9th news, the official public account of China National Nuclear Corporation yesterday (October 8th) released a blog post, announcing that it has successfully opened up the entire technological process of separating boron-10 isotope by low-temperature distillation method, and stably produced an enriched boron-10 product with an abundance of 70%, indicating that China has mastered the large-scale technology of low-temperature distillation separation of boron-10 isotope with completely independent intellectual property rights.
Project Background
With the increasing global demand for clean energy and nuclear power safety, it has promoted the demand for boron-10 in the construction and operation of nuclear power plants. Facing the current situation of the lagging level of large-scale production of boron isotopes in China, the Atomic Energy Institute has deeply cultivated the basic research and application development of stable isotope separation technology.
TapTechNews quoted the blog post of the public account that boron-10 has excellent neutron absorption characteristics and plays a crucial role in the field of nuclear industry technology. Boron-10 acid is one of the important products of boron-10, and the natural abundance of boron-10 is only 19.8%.
In nuclear power plants, the use of enriched boron-10 acid can greatly reduce the overall amount of boric acid, effectively reduce the risk of boric acid crystallization, and slow down the corrosion of the cooling system, thereby improving the safety and economy of nuclear power plant operation.
Project Results
With the support of the National Defense Science and Technology Bureau and China National Nuclear Corporation, the Atomic Energy Institute carried out the research project of Engineering Technology Research on Separation of Boron Isotopes by Low-Temperature Distillation Method, and Hu Shilin, an academician of the Chinese Academy of Engineering and the chief scientist of China National Nuclear Corporation, served as the person in charge.
Hu Shilin's team, without fearing difficulties, bravely climbed the peak of science and technology. After years of unremitting efforts and collective wisdom, they innovatively developed a whole set of advanced boron-10 isotope separation processes, successfully established a full-flow bench device for preparing boron-10 by low-temperature distillation method, achieved continuous and stable operation, and stably produced an enriched boron-10 product with an abundance of 70%.
Project Significance
This successful mastery of the technology indicates that China has completely independent intellectual property rights in the separation technology of boron-10 isotopes. This means that China's technological independence in this field has been enhanced, reducing the dependence on external technologies.
Mastering the technology of separating boron-10 isotopes by low-temperature distillation helps to improve China's international competitiveness in related fields such as nuclear energy and materials science.
This successful application of the technology will promote the development of related industries, especially in the fields of nuclear energy, materials and medical care. The stable production of enriched boron-10 products will provide more reliable raw materials for these fields.
