Status for Fretting-Wear Study of Nuclear Structural Components
-
摘要: 蒸汽发生器传热管与支承结构、燃料棒包壳与格架等反应堆结构在高温高压水环境下,由于流致振动导致的微动磨蚀破坏是影响反应堆安全运行的重要因素之一。温度、水化学条件是影响结构磨蚀特性的关键参数,文中对各国的磨蚀研究现状进行了介绍。Abstract: Flow-induced vibration of steam generator tubes or fuel rods results in fretting-wear damage due to impacting and rubbing of the tubes against their supports or fuel rods against their grids. Tubes and fuel rods are working at high temperature and pressure. The damages should be bad for the safety of nuclear reactors. Temperature and water chemistry are the key parameters for fretting-wear. This paper introduces the status for the studies of fretting wear in the world.
