“…The molten salt was a LiCl-KCl eutectic, and two different electrorefiners (ER) were used: Mark-IV ER for driver fuel and Mark V-ER for blanket fuel [ 58 – 61 ]. Pyroprocessing of SNF in molten salts has several advantages, such as a reduced concern for criticality, flowsheet simplicity, minimization of liquid waste and the ability to handle shorter cooling times and high burn up of fuels [ 62 ].…”

“…In electrowinning, actinide oxides are dissolved in alkali/alkaline earth halides, and the actinide metal is electrodeposited. In the reduction of actinide oxides in molten LiCl or CaCl 2 , the initial deposition of Li or Ca on the oxide is observed [ 62 ]. Both methods commonly use Pt, W, C or Ag electrodes, operate on a scale of several hundred grams of the molten salt [ 64 , 65 ] and are usually performed at 500°C or above (depending on electrolyte composition) [ 62 ].…”

Uranium metal is associated with several aspects of nuclear technology; it is used as fuel for research and power reactors, targets for medical isotope productions, explosive for nuclear weapons and precursors in synthetic chemistry. The study of uranium metal at the laboratory scale presents the opportunity to evaluate metallic nuclear fuels, develop new methods for metallic spent fuel reprocessing and advance the science relevant to nuclear forensics and medical isotope production. Since its first isolation in 1841, from the reaction of uranium chloride and potassium metal, uranium metal has been prepared by solid-state reactions and in solution by electrochemical, chemical and radiochemical methods. The present review summarizes the methods outlined above and describes the chemistry associated with each preparation.

“…Wanigasekara et al [ 140 ] checked the possibility of application ILs as a medium for UO 2 electrodeposition. In 2011 Jagadeeswara Rao [ 141 ] reported electrodeposition of metallic uranium from the mixture of ([MPPip][Tf 2 N]) with U(IV). These authors reported that at potential of −2.8 V vs. Fc│Fc + metallic uranium was deposited on platinum working electrode.…”

Potential Application of Ionic Liquids for Electrodeposition of the Material Targets for Production of Diagnostic Radioisotopes

An overview of the reported electrochemistry studies on the chemistry of the element for targets for isotope production in ionic liquids (ILs) is provided. The majority of investigations have been dedicated to two aspects of the reactive element chemistry. The first part of this review presents description of the cyclotron targets properties, especially physicochemical characterization of irradiated elements. The second part is devoted to description of the electrodeposition procedures leading to obtain elements or their alloys coatings (e.g., nickel, uranium) as the targets for cyclotron and reactor generation of the radioisotopes. This review provides an evaluation of the role ILs can have in the production of isotopes.
