【摘要】 反应堆堆芯是反应堆最重要的部分,进行精细的堆芯设计以及安全分析,必须进行核热耦合分析,使反应堆具有更真实的安全裕量。脉冲堆作为反应堆重要类型,在测试和培训、研发、医用同位素生产等方面发挥重要作用,本文总结了核热耦合应用中的相关技术方法,并结合在脉冲堆上已开展的核热耦合研究,考虑基于蒙特卡罗与子通道程序耦合的方法在脉冲堆上的应用,为下一步开展脉冲堆瞬态物理热工分析提供理论基础。更多还原

【Abstract】 The reactor core is the most important part of the reactor. The detailed core design and safety analysis must be carried out, so that the reactor has a more real safety margin. As an important type of reactor, TRIGA reactor plays an important role in testing, training, research and development, medical isotope production, etc. This paper summarizes the relevant technology and methods in the application of nuclear-thermal coupling, and combines the research on nuclear-thermal coupling on TRIGA reactor. Considering the application of Monte Carlo coupled with sub-channel program in TRIGA reactor, this paper provides a theoretical basis for the next step of transient physical thermal analysis of TRIGA reactor.更多还原
