Abstract
We describe an experimental installation, a model, a test procedure, and results from experimental investigations into hydrodynamics and heat transfer during the boiling of an eutectic sodium-potassium alloy in a system of two parallel channels that simulate the operating conditions of channels in a typical fast-neutron reactor.
