METHOD OF CLEANING IRRADIATED NUCLEAR FUEL Russian patent published in 2013 - IPC G21C19/42

Abstract RU 2499306 C1

FIELD: physics.

SUBSTANCE: separation of electropositive fission products from fission of alkali metal chlorides is carried out by chemically reducing the electropositive fission products on molybdenum metal. Separation of a portion of the electropositive fission products (zirconium and niobium) is carried out based on an exchange mechanism to form zirconium and niobium dioxides. Molten molybdenum is removed in form of molybdenum pentachloride by bubbling chlorine gas through the salt melt.

EFFECT: invention provides high percentage of extraction of electropositive fission products, a simple apparatus scheme, cheap process of treating nuclear fuel.
