Abstract
A liquid metal pump assembly is disclosed as being adapted to be disposed as one of a plurality of like pump assemblies in a continuous, closed array about a core of a nuclear reactor system. Each pump assembly comprises a pipe for receiving and directing a pumped, intermediate liquid metal through the pump assembly, and first and second duct modules disposed on either side of the pipe. Each duct module comprises primary ducts for receiving and directing a primary liquid metal in a first direction, and intermediate ducts in communication with the pipe for directing a first flow of the intermediate liquid metal therethrough in a second direction opposite to the first direction. A mechanism illustratively in the form of a pair of field coils, generates and directs a main magnetic field to each of the primary and intermediate ducts of the first and second duct modules, whereby the interaction of the main magnetic field and the first flow of the intermediate liquid metal generates a first current flow through the intermediate ducts and the primary ducts, and pumps the primary liquid metal through the pump ducts. Further, at least one magnetic element is disposed adjacent one of the fir…
