In this paper main focus is placed on experimental evaluation of single stream MOlten Salt Actinide Recycler & Transmuter (MOSART) system fuelled with different compositions of plutonium plus minor actinide trifluorides (AnF3) from LWR spent nuclear fuel (SNF) without U-Th support. This paper summarizes main experimental results of ISTC#1606 related to physical & chemical properties of fuel salt, container materials for fuel circuit, and fuel salt clean up of MOSART system. As result of ISTC#1606 studies claim is made, that the 7Li,Na,Be/F and 7Li,Be/F solvents selected for primary system appear to resolve main reactor physics, thermal hydraulics, materials compatibility, fuel salt clean up and safety problems as applied to the MOSART concept development.

  • Kinetics and Mechanism of Distribution of Lanthanum Ions in Mno2 Structure in the Presence of Fluoride Ions E.S
    Int. J. Corros. Scale Inhib., 2020, 9, no. 1, 219–227 219 Kinetics and mechanism of distribution of lanthanum ions in MnO2 structure in the presence of fluoride ions E.S. Guseva Yu.A. Gagarin Saratov State Technical University, Engels Institute of Technology (branch), ul. Politekhicheskaya, 77, 410054 Saratov, Russian Federation Е-mail: [email protected] Abstract The study focused on improving the electrical characteristics of a MnO2 electrode by cathodic incorporation of lanthanum from an aprotic organic solution of a salt containing fluoride ions made it possible to identify the extent of participation of each component in the formation of new LiхLауMnO2F phases with a structure that facilitated the process of subsequent intercalation–deintercalation of lithium and its accumulation in the cathode material, and to develop technology recommendations for the modification process conducted in potentiostatic mode: 0.5 mol/L lanthanum sulfanilate solution in a mixture of propylene carbonate with dimethoxyethane, PC+DME (1:1), which contained LiF (14 g/L); the potential was Ec = 2.9 V (relative to SCE); the time was 30 min. Subsequent lithium intercalation–deintercalation was carried out in 0.8 M solution of LiClO4 in the PC+DME (1:1) mixture at the same potential. The presence of lanthanum cations that were incorporated into the structure of the LiAl anode prevented the inhibition of anodic dissolution (corrosion) during the charge-discharge process. Lanthanum cations contributed to the elevated inhibition of anodic processes and increased the number of cycles resulting from the electrode cycling [1, 2]. Key words: fluoride ions, lanthanum, electrochemical modification, intercalation, lithiation, manganese dioxide, lithium, anode corrosion resistance.

Coopers Building Church Street, © Designated Contracting States: BE DE FR GB Liverpool L1 3AB (GB) @ Composition for use as solid state electrolyte and solid state cell employing same. There is disclosed a composition which can be used as a solid state electrolyte comprising at least 70 mole percent of cerium trifluoride and/or lanthanum trifluoride, an alkaline earth metal compound e.g. fluoride, and an alkali metal compound e.g. lithium fluoride. The invention relates to a composition which can be used as a solid state electrolyte composition. Ionic conductivity is usually associated with a flow of ions through an aqueous solution of metallic salts. In the vast majority of practical uses of ionic conductors, i.e., as electrolytes for dry cell batteries, the aqueous solution is immobilized in a paste or gelled matrix to overcome the difficulties associated with handling and packaging a liquid. However, even after immobilization, the system is still subject to possible leakage, has a limited shelf life due to drying out or crystallization of the salts and is suitable for use only within a limited temperature range corres- ponding to the liquid range of the electrolyte.
