ABSTRACT:
A liquid metal cooled fast breeder nuclear reactor wherein the fuel assembly includes some breeder fuel sub-assemblies having electromagnetic brakes and fluidic valves of the controlled vortex kind for controlling the coolant outlet temperature. The coolant flow through each breeder sub-assembly is divided into a major flow fraction by way of the fluidic valve and fuel pins a minor flow fraction by way of the electromagnetic brake which is sensitive to the temperature of coolant flow. A control component of force for the fluidic valve is derived from the back pressure of the brake so that as the power output of the sub-assembly increases the braking effect diminishes and flow of coolant through the fluidic valve is increased.
