Modernization and Capability Investigation of the MATRIX Electromagnetic Pump Analysis Code

Electromagnetic (EM) pumps are a major component in the safe operation of liquid metal–cooled nuclear reactors and can also be used in any other application in which a conductive fluid is being pumped through a system. During the design of an EM pump, it is useful to model its operating characteristics for pump sizing, flow capabilities, and other design checks. The EM pump analysis code known as MATRIX is a prime example of a tool that can be used for such pump modeling. This paper introduces the modernization and capability investigation efforts completed on MATRIX. An output data comparison of the modernized code is made between both the legacy code and the measured EM pump. Further improvement of MATRIX through data analysis and flow correction techniques is explained.
