摘要
双流体熔盐快堆(DFFR)尚处于概念研发阶段,很多主要设计参数还未确定。本文主要依据DFFR概念进行初步的反应堆设计,并初步评估了这些设计参数与反应堆物理特性的关系,以验证该型反应堆的可行性。评估主要采用2种方法:(1)基于蒙特卡洛理论的堆芯临界计算;(2)基于传热理论的堆芯热工水-力计算。结果显示,DFFR可以在选定的功率下达到临界并且获得与设计值一致的热工参数。通过对DFFR堆芯物理及热工特性的评估,初步验证了该型反应堆概念设计的理论可行性。
The development of DFFR stays in the phase of conceptual design, which leads to the main discussion of this work that is to quantitatively evaluate the feasibility of this reactor type and the effects of those parameters on the reactor physical behavior. The evaluation includes two parts: the criticality calculation based on the Monte Carlo theory and the thermal-hydraulic calculation based on the heat transfer theory. The result shows that the DFFR can achieve the criticality with expected operational parameters and the feasibility of this reactor is therefore preliminarily proven.
