Experimental characterization of the flowline of a lithium film formed using an electromagnetic thruster for a RAON prototype charge stripper
Abstract
This paper describes the variable optimization of a lithium charge-stripper device and experimental characterization of lithium film formation for the charge removal of uranium using a magnetohydrodynamic liquid metal circulation system. To this end, liquid lithium thin films were developed using an electromagnetic thruster through collisions between a liquid lithium jet and a planar deflector. The lithium film flow characteristics were analyzed through simulation and waterjet experiments in terms of the liquid lithium film thickness. To circulate liquid lithium, a mechanically safe electromagnetic thruster with precise pressure control was designed by analyzing its electromagnetic and hydraulic parameters through finite element simulation. The analysis of the geometric arrangement of the permanent magnet and input current of the thruster revealed that that compared to the existing electromagnetic thruster, the nominal input current of the newly-constructed one reduce by 57% and its weight reduced to 6%, and it required minimized input power, while facilitating maintenance. Further, the formation of a liquid lithium thin film with a thickness of 22 μm required to obtain the 79+ charge state of uranium was verified at an input current of 107 A.
