Separation of thorium from uranium ore SpringerLink

2019-12-7 · Thorium-230 has many research applications, but there is not a commercial source of this isotope. However, since 230Th is part of the 238U decay chain, it can be separated from naturally occurring uranium. In this work, a novel procedure was developed to separate thorium from uranium ore, consisting of leaching, liquid–liquid extraction, precipitations and ion exchange chromatography.

SEPARATION OF URANIUM, PLUTONIUM AND

Abstract. A process is given for removing plutonium and/or fission products from uranium fuel. The fuel is dissolved in molten zinc--magnesium (10 to 18% Mg) alloy, more magnesium is added to obtain eutectic composition whereby uranium precipitates, and the uranium are separated from the Plutoniumand fission-product- containing eutectic.

Uranium conversion and enrichment ScienceDirect

2020-1-1 · Uranium conversion, which also incorporates uranium refining, is a necessary processing step for the production of nuclear fuel. The primary purpose of refining is to remove impurities from the uranium that could lead to deleterious effects during fuel manufacturing, enrichment, and irradiation in a nuclear power reactor.
