<p>A pump assembly (18) is disclosed for transferring the internal energy from a second or intermediate liquid metal to a first or primary liquid metal. The pump assembly comprises a pump duct (72) for receiving the first liquid metal and a primary generator duct (70) for receiving a first flow of the pumped, intermediate liquid metal. A first or main (76) means in the illustrative form of a plurality of field coils generates and applies a main magnetic field through the pump and the primary generator ducts, whereby a first current flow is established through the pump and primary generator ducts and the primary liquid metal is pumped. An auxiliary generator duct (102) receives a second flow of the pumped, intermediate liquid metal. An auxiliary means (96), illustratively in the form of permanent magnets, generates an auxiliary magnetic field through the auxiliary generator duct, whereby the interaction of the auxiliary magnetic field and the second flow of the pumped, intermediate liquid metal generates a second current flow to excite the field coils.</p> |
