摘要： This disclosure describes nuclear fuel salts usable in certain molten salt reactor designs and related systems and methods. Binary, ternary and quaternary chloride fuel salts of uranium, as well as other fissionable elements, are described. In addition, fuel salts of UCl x F y are disclosed as well as bromide fuel salts. This disclosure also presents methods and systems for manufacturing such fuel salts, for creating salts that reduce corrosion of the reactor components and for creating fuel salts that are not suitable for weapons applications.

摘要： An insulated solution injector (200) may include an outer tube (202) and an inner tube (204) arranged within the outer tube. The outer tube and the inner tube may define an annular space (203) therebetween, and the inner tube may define a solution space (205) within. The annular space may be configured so as to insulate the solution within the solution space. As a result, the solution may be kept to a temperature below its decomposition temperature prior to injection. Accordingly, the decomposition of the solution and the resulting deposition of its constituents within the solution space may be reduced or prevented, thereby decreasing or precluding the occurrence of a blockage.

摘要： The invention relates to energy mechanical engineering and can be used in power installations involving a liquid-metal heat carrier. A mass transfer apparatus including a housing and, provided therein, a flow reaction chamber filled with a solid-phase granulated oxidation agent, and an electric heater positioned in the reaction chamber. The housing of the apparatus is equipped with a repository for reserves of the solid-state granulated oxidation agent, said repository being located below the reaction chamber and being made in the form of a cup having a bottom, said cup being connected to the reaction chamber. The technical result consists in extending the operational duration of the mass transfer apparatus.

摘要： This invention generally concerns radioactive decontamination of deposits on components in a nuclear power plant and is specifically concerned with improved compositions, systems and methods for disrupting, dissolving, removing and reducing at ambient temperature radionuclides formed on the primary side surfaces of components in a pressurized water reactor and the internal components of a boiling water reactor. The methods include identifying the structure, taking the structure out of operational service, contacting the structure with an aqueous solution (e.g., a recirculating flow or static immersion), and adding an effective amount of elemental metal in solid form to the aqueous solution.

摘要： Die Erfindung betrifft Kondensationskammerkühlsystem, umfassend eine Kondensationskammer (42) für einen Siedewasserreaktor (46) und wenigstens einen außerhalb der Kondensationskammer (42) angeordneten Wärmetauscher (48). In der Kondensationskammer (42) ist ein längliches Kühlmodul (10, 54) vorgesehen, welches in seinem oberen Bereich einen Verdampfungsraum (12) umfasst, wobei das Kühlmodul (10, 54) derart in der Kondensationskammer (42) angeordnet ist, dass der Verdampfungsraum (12) oberhalb eines Höchstfüllstandniveaus (14) der Kondensationskammer (42) befindlich ist. Das Kühlmodul (10, 54) umfasst fernerhin wenigstens ein Steig- (18) und ein Fallrohr (20), welche mit ihren jeweiligen oberen Enden in den Verdampfungsraum (12) münden und mit ihren jeweiligen unteren Enden in der Kondensationskammer (42). Eine erste Druckleitung (56) ist vom Verdampfungsraum (12) zum Wärmetauscher (48) vorgesehen und von dort eine zweite Druckleitung (58), welche in der Kondensationskammer (42) unterhalb des Mindestfüllstandsniveaus (16) mündet. Somit ist durch die Kondensationskammer (42), die Druckleitungen (56, 58), das Kühlmodul (10, 54) und den Wärmetauscher (48) ein passiver geschlossener Kühlkreislauf gebildet.

摘要： Method for controlling the introduction of zinc to a nuclear power reactor to control radiation build-up wherein zinc ions are introduced into the reactor water to counteract loss of zinc within the reactor system. In the process, the rate of introduction of zinc ions into the reactor water is balanced with the rate at which zinc ions are lost from the reactor.
