Abstract: A connector assembly for transferring high-frequency current into or from a Litz-wire electrical cable having multiple conductor strands includes a transition connector component, a terminal connector component, and a coupling collar. The transition component has an annular groove which receives the splayed ends of the multiple conductor strands and makes electrical connection therewith by soldering of the conductor strand ends to the transition component at the groove. The transition component also has a central opening through it for providing flow communication with the internal coolant flow channel of the electrical cable. The terminal connector component has an orifice through it for establishing flow communication between the transition component opening and an external source of coolant. The terminal component also has a tab projecting from it for making an external electrical connection. The transition and terminal components are electrically connected together by fasteners.

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.

Abstract: A heat exchanger and electromagnetic pump assembly is disclosed as comprising a heat exchanger including a housing for defining an annularly shaped cavity and supporting therein a plurality of tubes. An electromagnetic pump is disposed beneath the heat exchanger and is comprised of a plurality of flow couplers disposed in a circular array. Each flow coupler is comprised of a pump duct for receiving primary liquid metal, and a generator duct for receiving an intermediate liquid metal. A downcomer tube is disposed centrally of the assembly and passes through the annularly shaped cavity and the array of flow couplers to discharge the intermediate fluid into a first plenum chamber. The first plenum chamber is disposed in communication with the generator ducts of all of the flow couplers, thus permitting the intermediate liquid metal to flow upward therethrough.

Abstract: A flow characteristic regulating electromagnetic flow coupler is disclosed as comprising a pump duct and a generator duct for connection in separate flow circuits containing electrically conductive fluid. Circuit means electrically connect the separate fluid in each of the pump and generator ducts for conducting electric current through the fluid in each of the pump and generator ducts transversely of the fluid flow therethrough. Means are provided for applying respectively first and second magnetic fields through the fluids of the generator and pump ducts transversely of the current and fluid flow therethrough, whereby the fluid driven through the generator duct forces the fluid to flow through the pump duct.
