摘要: 根据熔盐堆的流动特性,采用多群扩散理论,建立液体燃料熔盐堆的三维中子动力学模型和流动传热模型,开发针对液体燃料熔盐堆的三维核热耦合程序,并分析瞬态情况下MOSART堆的物理热工特性.结果表明:堆芯热工参数的瞬态变化直接影响物理参数的变化,液体熔盐堆具有较明显的温度负反馈特性.

Abstract: Considering fuel flow effect of reactor, neutron dynamic model was derived based on particle conservation equation and coupled with flow and heat transfer model. We developed a three-dimensional neutron/thermal-hydraulic coupled code and analyzed psychical property and thermal hydraulic characteristic of MOSART in transient state. It indicates that thermal hydraulic parameters influence greatly to psychical property of the core. Temperature negative feedback of liquid-fuel MSR is obvious.

Key words: molten salt reactor, three-dimensional simulation, coupled neutronics and thermal hydraulics, transient state analysis
