摘要: In a molten-salt reactor, a common vessel contains the reactor core, a neutron-moderating mass pierced by passages for the circulation of the fuel salt, at least one primary heat exchanger which is located close to the reactor core and through which the hot fuel salt passes after discharge from the core, pumps for circulating the cold fuel salt from the heat exchangers back into the reactor core. The free spaces defined within the reactor vessel between the core, the heat exchangers and the pumps except for the passages in which the molten fuel salt is circulated are packed with material which is compatible with the fuel salt.

摘要: Fission of uranium-235 produces a wide range of fission products. Of particular importance is the production of molybdenum-99 due to its uses in the medical field. Fission products can be extracted from a molten salt reactor through electrochemical deposition by utilizing an electrode submerged in the flow of irradiated molten salt. However, this is likely to disrupt the redox of the irradiated molten fuel leading to harmful corrosion of the reactor. The present invention utilizes three electrode sets to capture fission products from irradiated molten salt of a molten salt reactor, monitor the redox behavior of the irradiated molten salt, and maintaining the balance of uranium ions to avoid harmful corrosion to the reactor's core.

摘要: A fission product trap for a reactor system, such as for a pipe connection and/or a pump shaft of a pump of the reactor system, includes a porous container. The porous container may be mounted about the pipe connection and/or pump shaft and include an absorbing material contained therein. The absorbing material may be configured to collect fission products emitted from the pipe connection and/or the pump shaft. The fission product trap further includes an assembly encompassing the porous container and that defines a volume about the porous container and the pipe connection and/or the pump shaft.

摘要: In various embodiments, the stabilizing face ring joint flange and assemblies thereof can be adapted to include a ring joint gasket and resist leaks when a fluid flowing through a pipe at high temperatures and pressures. The stabilizing face ring joint flange assembly with the ring grooves in each flange can be situated in such a way that once full compression is achieved on the ring groove by the gasket, raised faces of the two flanges can meet to ensure that the rotation of the pump or any potential perpendicular loading do not provide a stress on the gasket that would cause the gasket to deform or cause a seal to be lost.

摘要: A molten salt nuclear reactor of the fast neutron reactor type may be designed as a reactor vessel free of moderator or at the very least of a moderator enabling a reactor to be qualified as a thermal neutron reactor, having a shape exhibiting symmetry of revolution surrounded by another vessel at the periphery of the reactor vessel thereby delimiting a guard gap filled with an inert liquid salt which acts as a coolant for removing the decay heat from the reactor by conduction through the reactor vessel.

摘要: Molten salt nuclear fission reactor including a core through which a fuel salt flows, a unit for circulating the fuel salt, a primary heat exchanger through which a heat-transfer salt flows, a primary enclosure which is impermeable to liquid salts and contains the reactor core, and a shelter. The reactor includes a parallelepiped matrix including alternating layers of fuel salt channels, and layers of heat-transfer salt channels. The matrix forms both the reactor core, in which the fission occurs, and the primary heat exchanger of the reactor. The circulating unit is entirely located within the primary enclosure and are configured to extract the fuel salt from one portion of the fuel salt channels on one side of the matrix and to propel the fuel salt into the other portion of the channels on the same side of the matrix.

摘要: The power plant system includes a molten salt reactor assembly, a thermocline unit, phase change heat exchangers, and process heat systems. The thermocline unit includes an insulated tank, an initial inlet, a plurality of zone outlets, and a plurality of gradient zones corresponding to each zone outlet and being stacked in the tank. Each gradient zone has a molten salt portion at a portion temperature corresponding to the molten salt supply from the molten salt reactor being stored in the tank and stratified. The molten salt portions at higher portion temperatures generate thermal energy for process heat systems that require higher temperatures, and molten salt portions at lower portion temperatures generate thermal energy for process heat systems that require lower temperatures. The system continuously pumps the molten salt supply in controlled rates to deliver the heat exchange fluid supply to perform work in the corresponding particular process heat system.
