6.4  Special considerations

 

In addition to the normal function of condensing the steam which is discharged from the LP turbines, condensers on nuclear power stations are designed to provide a heat sink for the removal of heat from the reactors.

These condensers are fitted with steam and water dumping facilities of the pressure breakdown type. The condenser structures are suitably reinforced to take the reaction forces and erosion effects of high velocity flows from the steam dump diffusers. Condensing tube surfaces are protected by impingement plates and desuperheating sprays. A more detailed account of the steam and water dumping requirements on nuclear power stations is covered in Chapters 1 and 2 of this Section.
