摘要
介绍了一种评价压水堆核电厂喷淋系统中水锤效应的方法,并以我国某二代改进型M310核电厂喷淋系统为原型,对系统的水锤瞬态力进行了计算。结果表明:采用安全壳喷淋系统直接喷淋时管道中水锤产生的瞬态力远小于喷淋立管和环管充水后的自重,由水锤瞬态力导致的管道位移很小,该力在管道支吊架可承受的范围内。
A method for evaluating the water hammer effect in the sprinkling system of a pressurized water reactor nuclear power plant was described and with the sprinkling system in an improved type( M310) nuclear power plant in China inthe second generation serving as the prototype,a calculation was performed of the transient forces produced by the water hammer in the system. It has been found that when the containment dome sprinkling system is used to conduct a direct sprinkling,the transient forces produced by the water hammer in the pipelines are far less than the selfweight of the sprinkling vertical tubes and annular tubes when they are filled with water. The displacement of the pipelines arisen from the water hammer-resulted transient forces is very small,thus the force resulted from such a displacement is within the range bearable by the supporters and hangers on the pipelines.
