【摘要】 在核电反应堆及研究型反应堆系统中,水锤是一种较为常见的现象。反应堆循环水供水系统、蒸汽系统及其他辅助系统(如热阱)和水力测功系统等都曾发生过多起水锤现象。水锤现象往往伴随很响的锤击声,轻则引起相邻管道振动,重则导致结构性缺陷,造成管网漏液甚至供给中断,时刻威胁反应堆运行安全。本文调研了国内外水锤现象的研究现状及进展,重点分析了反应堆系统管路水锤现象的成因以及采取的应对措施。更多还原

【Abstract】 Water hammer effect is a common phenomenon in nuclear power reactors and research reactor systems. Several large or small water hammer phenomena occurred in the reactor water supply system, steam system and its auxiliary system pipelines, such as hot trap system, hydraulic system and hydraulic dynamometer system. The phenomenon of water hammer is often accompanied by loud hammering sound, which can either cause the vibration of adjacent pipelines or lead to structural defects, which would result in liquid leakage and even supplement interruption of the pipeline network, threatening the operation safety of the reactor system.This paper investigates the research status of water hammer phenomenon at home and abroad, and focuses on the countermeasures taken to the water hammer phenomenon in the reactor system pipeline.更多还原
