摘　　要：核电站蒸汽发生器淤泥沉积是蒸汽发生器材料发生腐蚀和损坏的重要原因。分别介绍了水化学控制、停堆保养、分散剂加入及磁性过滤等减少积污的方法。水化学控制、有机胺的使用,以及磁性过滤器的使用均能有效减少进入蒸汽发生器中淤泥的沉积量,而分散剂的使用可使蒸汽发生器中的淤泥分散排除,减少沉积。The sludge deposition in steam generator of nuclear power plant is always an important cause leading to corrosion and damage of materials used in steam generator.Methods for reducing the sludge deposition,such as chemical control of water,conservation during reactor shutdown,injecting dispersant and application of magnetic filter etc.,has been presented respectively.The chemical control of water,as well as application of organic amine and magnetic filter all can effectively reduce the deposition of sludge entering into the steam generator,while using dispersant can make the sludges in the steam generator to be dispersively discharged,reducing their deposition.
