Extraction of fission products from molten salt via redox reaction with reducting agents

A system comprising:

• a fuel salt system configured to circulate an irradiated fueled molten salt comprising fission products through a molten salt loop of a molten salt reactor system, wherein the molten salt loop comprises piping, an access vessel, a reactor core, a pump, and at least one heat exchanger;
• and
• a fission product extraction system fluidly coupled to piping of the molten salt loop, the fission product extraction system comprising
• a pipe connected to the piping of the molten salt loop;
• a metallic structure partially coated in a reducing agent extending from the pipe into the piping of the molten salt loop such that the metallic structure makes contact with the irradiated fueled molten salt;
• wherein the metallic structure is connected to a removable rod of the fission product extraction system;
• and
• wherein the fission product extraction system is operable to capture the fission products by redox reaction between the reducing agent and the fission products such that the fission products plate onto the metallic structure.

A method for capturing fission products from irradiated fueled molten salt of a molten salt reactor system comprising:

• circulating a flow of irradiated fueled molten salt through a molten salt loop of the molten salt reactor system;
• wherein the irradiated fueled molten salt comprises fission products;
• inserting a metallic structure into piping of the molten salt loop, wherein the metallic structure is at least partially coated in a reducing agent;
• capturing the fission products on the metallic structure via a chemical redox reaction between at least the reducing agent and the fission products;
• and
• removing the metallic structure from the piping of the molten salt loop.
