Some embodiments include an chemical separation mechanism for a molten salt reactor where the molten salt may include fission products. In some embodiments, the chemical separation mechanism includes a molten salt receptacle with a molten salt disposed within, a solvent receptacle having a solvent disposed within; an electrode; and an electrode mechanism. In some embodiments, the electrode mechanism may be configured to submerse the electrode into the molten salt receptacle such that a chemical reaction occurs between the electrode and one or more of the fission products in the molten salt. In some embodiments, the electrode mechanism may submerse the electrode into the solvent receptacle such that a chemical reaction occurs resulting in one or more of the fission products being deposited into the solvent.

An electromagnetic induction pump includes a tubular internal inductor having internal combs and internal coils between teeth of the internal combs. The inside of the internal inductor forms a cavity. An internal tube is positioned around the internal inductor. A pumping canal allows circulation of a fluid. The canal is between the internal tube and external tube. A tubular external inductor is positioned around the external tube and includes external combs and external coils positioned between teeth of the external combs. An electromagnetic pump includes a movement device for moving the internal combs, and varies the radial clearance between the internal combs and internal tube, having a first part positioned inside the internal inductor and in connection with the internal combs to move them radially, and a second part extending at least partially outside of the internal inductor and connected to the first part to control the first part.

A masking element with an opening is disposed on the side of a core support structure. A flow stack wall defines a plurality of inlets. At least one inlet aligns with the masking element opening when the flow stack is mated with the masking element. A flow control assembly within the flow stack is configured to restrict flow of fluid within the flow stack.

A sodium-cooled nuclear reactor includes at least one electromagnetic pump assembly and a backflow reduction pipe. The backflow reduction pipe may include an inlet, an outlet, at least one tubular section having a first length and a first diameter, and at least one fluid diode section between the inlet and the outlet.

The invention relates to nuclear power engineering and is intended for using in power plants with a reactor with a heavy liquid metal coolant (HLMC) based on lead or on lead-bismuth alloys.

The invention makes it possible to increase the radiation protection efficiency for the in-vessel equipment of a nuclear reactor, to increase the heat storage capacity of the primary circuit, to reduce the nuclear reactor weight, and to improve its strength characteristics.

In the in-vessel space of a nuclear reactor, which is not occupied by the necessary equipment, containers filled with a material that reflects or absorbs neutrons, with a heat capacity greater than that of the coolant, are installed with gaps ensuring the coolant flow, while the containers are placed in such a way that the resulting gaps form channels with a turbulent coolant flow to cool these containers at a flow rate corresponding to the nominal power output level of the nuclear reactor.
