摘要
针对熔盐堆燃料和慢化剂的特点,对压水反应堆热工水力计算程序CATHARE进行了适应性改造。使用改造后的程序进行熔盐堆单通道流体的物理和热工耦合计算分析。分析计算表明,改造后的CATHARE程序可以模拟反应性引入事故和流量引入事故等瞬态工况的堆芯热工物理耦合过程。
According to the characteristics of fuel salt and moderator in Molten Salt Reactor, the PWR thermal-hydraulic code CATHARE is modified, which is applied to study the behaviour of a single-channel of the MSR core. The calculation results show that CATHARE can predict the coupling of thermal-hydraulic and neutronics in steady-state conditions and under several transients （i.e., reactivity variations and fuel mass flow rate variations）.
