Separation of fission products in a molten salt reactor via adsorbent frameworks

A system comprising:

• a molten salt reactor system comprising a molten salt, a reactor core, and an extraction system;
• the extraction system coupled to the molten salt reactor system and configured to receive a flow of molten salt comprising fission products produced in the reactor core;
• an absorbent framework extending from the extraction system into the molten salt by an attachment rod;
• wherein the attachment rod is configured to facilitate removal of the absorbent framework from the molten salt;
• wherein the absorbent framework comprises a temperature resistant cartridge configured to house an absorbent composition and enable flow of the molten salt therethrough;
• wherein the absorbent composition is configured to capture fission products from the molten salt by binding to the fission products via intermolecular force interaction between the absorbent composition and the fission products;
• wherein the absorbent composition is a metal-organic framework compound;
• and
• wherein the metal-organic framework compound comprises ZIF-4, or ZIF-8.
