本文分析了国际上生产99Mo同位素研究堆的现状和发展趋势,有针对性地提出了主产裂变99Mo同位素研究堆的设计理念,经初步优化设计,分析和论证了该堆的总体设计参数,给出了初步的运行模式、燃料经济性分析和99Mo同位素产量评估。结果表明,该堆在保证安全性的基础上,极大地提高了生产堆的经济性。表1列出了该反应堆的主要设计参数。 This paper analyzes the current situation and development trend of the 99Mo isotope research reactor in the world, and puts forward the design concept of the 99Mo isotope research reactor with the main production fission. After preliminary optimization design, the overall design parameters of the reactor are analyzed and demonstrated Out of the initial operating mode, fuel economy analysis and 99Mo isotope production assessment. The results show that the pile greatly improves the economy of the production pile on the basis of ensuring safety. Table 1 lists the main design parameters of the reactor.
