气体扩散法生产硼-10同位素的经济性分析

¹⁰B同位素在中子屏蔽和探测中有重要的作用，目前大规模生产硼同位素的方法主要是化学交换精馏法。随着¹⁰B市场需求的增加，在国产化取代进口的背景趋势下，探索硼同位素分离方法的优化和创新有重要意义。本研究分析了气体扩散法用于¹⁰B同位素分离的经济性，并根据市场实际情况估算产品成本。首先分析以BF₃为介质的单级扩散分离效应并估算级联规模，接着从设备投资及生产运行成本两方面进行硼同位素生产的经济性分析，并结合实际情况具体分析气体扩散法生产60%和96%丰度¹⁰B同位素产品的成本以及影响因素。通过经济性分析发现，采用BF₃扩散分离生产¹⁰B同位素的成本与市场价格接近且存在一定优化空间。本研究扩展和丰富了硼同位素分离方法，并证明了扩散法生产¹⁰B同位素在经济性方面存在潜力。

Economic Analysis of Boron-10 Isotope Production by Gas Diffusion Method

¹⁰B is an important isotope in neutron absorbing and neutron detecting. At present, the method of large-scale production of boron isotope is mainly chemical exchange distillation. In recent years, under the background of increasing market demand and localization, the exploration of optimization and innovation of boron isotope separation methods is of great significance. Economic analysis of producing ¹⁰B isotope by gas diffusion method is made, and product cost based on actual market conditions is estimated. First, single stage separation effect and cascade design is made using BF₃ as processing gas. Next, the economic analysis of boron isotope production is carried out from the two aspects of equipment investment and production and operation costs. Specific analysis of product with 60% abundance and 96% abundance of ¹⁰B based on the actual situation is made, and so is the influencing factors. The results show that the product cost of ¹⁰B by gas diffusion method is close to market price. Possible future optimization directions are pointed out. This work expands and enriches boron isotope separation methods. The economic analysis shows that the gas diffusion method for the separation and production of ¹⁰B isotope is a promising method for boron isotope separation.
