In general, the experience of titanium tubed turbine condensers is more than satisfactory. Steam side droplet erosion attack is however a concern in for example many of the Swedish and Finnish nuclear power plants. In this paper, the author`s experiences of droplet erosion as well as of remedies against droplet erosion are discussed. Possible remedies include plugging and installation of protective shields. The currently most favored remedy is partial retubing with more resistant materials. A number of accelerated tests have been performed in order to qualify potential tube materials regarding resistance towards droplet erosion. Highly alloyed stainless steels seem to have the best resistance. Some hard titanium alloys as well as nitriding of conventional titanium also seem promising. In severe cases a combination of several remedies may be necessary, e.g., partial retubing in combination with installation of a local moisture separator. For a new condenser the risk for droplet erosion can be reduced in the design stage.
