Abstract
An improved support for a tube bundle of a nuclear steam generator has a pair of plates separated by spacers and holding slotted disc springs used to mount tubes through tube holes of the pair of plates. The slotted disc springs deform upon installation and substantially eliminate tube vibration during use, thereby extending the useful life of the tubes. At the same time, the springs limit the pressure drop between sides of the support and enhance the heat transfer from the tubes.
