液态铅铋合金是先进反应堆加速器驱动的次临界系统(ADS)优选的靶材和冷却剂材料,液态铅铋流动速度场的测量是优化堆芯组件分布以及靶窗结构的一种重要手段.同时,冷却剂流动速度也是反映反应堆热工水力特征的重要参数之一.本文采用实验研究的方法,设计旋转搅动装置,通过对常温水与液态铅铋的流动速度场测量,验证了超声多普勒测速技术用于液态铅铋合金速度场测量的可行性. |

Lead bismuth eutectic (LBE) is considered as the candidate spallation target material and coolant for accelerator driven sub-critical systems (ADS).The viability of technical units,like fuel bundles arrangement in ADS,sophisticated information on the local velocity distribution is required.And,the flow velocity of coolant is an important thermal hydraulic parameter.In this paper,an agitation facility was designed to carry out experiments,the flow velocity distribution of water and LBE was measured for ultrasound Doppler velocimetry (UDV) which verified the feasibility to measure velocity distribution of liquid Lead bismuth eutectic (LBE). |
