Fuel assembly for a liquid-metal-cooled fast breeder reactor
Abstract
Abstract A fuel assembly for a liquid-metal-cooled fast breeder reactor includes a bundle of stainless-steel coolant duct with a flow separator being disposed in the annulus between the bundle of fuel pins and the coolant duct. The flow separator is spaced away from the coolant duct to provide a coolant channel adjacent to the coolant duct and includes an inner and an outer wall enclosing a chamber filled with liquid-metal coolant. Imperforate springs extending across the chamber between the inner and outer wall yield when the fuel bundle swells and prevent vertical flow of coolant within the chamber. Flow vents are provided in the outer panel to equalize pressure between the interior of the flow separator and the coolant channel and evacuated insulating spaces containing a single layer of screen wire each are provided in the inner wall of the flow separator.
