Performance of Magnetic Hydro-Dynamic Pump in Lead-Bismuth Eutectic Target Circuit (TC-1)
Electromagnetic (EM) pumps or linear magneto-hydrodynamic (MHD) machines have been used in foundries for transporting molten metals and in sodium-cooled nuclear reactors for circulating coolant. While the use of MHD pumps for heavy liquid metals has not been fully investigated, they are beginning to be used and studied in R and D facilities in support of the development of advanced nuclear reactors and waste transmutation systems. One MHD pump was tested in its full operation range in the University of Nevada, Las Vegas (UNLV). This pump is the prime mover in the pilot molten lead-bismuth eutectic (LBE) target circuit TC-1 that is designed in Russia (IPPE, Obninsk, ISTCno559) to accommodate an 800 MeV proton beam power of 1 MW. Under the rated head of 0.99 meter in TC-1, the pump capacity is 15 m3/hr. The hydraulic loss of the pump transport cross section was determined by measuring pressure drop and flow rate using piezometer and electro-magnetic flow meter in Russia. The relationship between input power and maximum head without circulation was obtained. As a result, the pump efficiency can be predicted based on the measured LBE flow rate and input power phase voltage and current. The performance curves of this MHD pump will be presented with the efficiency curves in this report.
