Experimental and numerical analyses of the magnetic field spatial measurement inside an electromagnetic pump channel duct

In the framework of the French Alternative Energies and Atomic Energy Commission (AEC) R&D program developing the Advanced Sodium Technological Reactor for Industrial Demonstration (ASTRID), it has been proposed to use in secondary cooling circuit an electromagnetic induction pump (EMP) due to its superior safety features such as: no moving parts in liquid metal and absolutely hermetic construction. However, detailed studies should be carried out in order to master operation of EMP and prevent undesirable phenomenon called MHD instability, which influence both the pump efficiency and operation.
