Bouyancy Effects on Sodium Coolant Temperature Profiles Measured in an Electrically Heated Mock-Up of a 61-Rod Breeder Reactor Blanket Assembly

摘要

The paper describes test results selected to demonstrate the effect of buoyancy on the temperature profiles in a 61-rod electrically heated mock-up of an LMFBR radial blanket assembly. In these assemblies, heat transfer occurs over a wide range of complex operating conditions. The range and complexity of conditions are the result of the steep flux and power gradients which are an inherent feature of the blanket region and the power generation level in an assembly which can vary from 20 to 1100 kW.
