The Comparative Analysis of Rectangular- and Helical-type DC Electromagnetic Pump for ADHRS in PGSFR

Abstract

A DC electromagnetic pump with rectangular- and helical-type was optimally analyzed for the active heat decay removal system (ADHRS) in prototype GenIV sodium fast reactor (PGSFR). The direct current (DC) electromagnetic pump was used to circulate liquid metal using Lorentz force which was vector product of current from electrode stub and magnetic flux density from permanent magnet. The two-types of DC electromagnetic was analyzed in the respect geometrical sizes, needed current, magnetic flux density, developed pressure while optimize each electromagnetic pump at pressure drop of 2 kPa and flow rate of 0.02 m3/s in liquid sodium temperature condition of 226 ℃. The FEM method using ANSYS code simulation and analytical method were used to determine specification of DC electromagnetic pump.
