Electrochemical studies on plutonium in molten salts

Rationalisation and optimisation of solid state electro-reduction of SiO2 to Si in molten CaCl2 in accordance with dynamic three-phase interlines based voltammetry

“…Similar or even larger apparent capacitance values were observed in molten CaCl 2 previously [21][22][23][24]26] but, to our best knowledge, mechanistic analysis is rare in the literature. The apparent capacitance on the W-wire (and also on other metal electrodes) may be compared with the pseudo-capacitance in some supercapacitors, resulting from redox active species on the surface of the electrode [30][31][32].…”

“…In the rest of the potential range, the CV showed small, slightly sloped, and paired parallel negative currents in the forward and backward potential scans. These background or residual currents were commonly observed in previous works [21][22][23][24]26] and may be described by an equivalent circuit of an apparent capacitor connected in parallel with a resistor. The resistor represents the electron transfer resistance of the electrode/electrolyte interface due to likely the reactions of impurities in the molten salt (e.g.…”

Lanthanides extraction processes in molten fluoride media: Application to nuclear spent fuel reprocessing

“…The technique joins up with other works dealing with the extraction of actinides and Ln by chemical precipitation of oxides with a large excess of oxides [19].…”

Reactor physic and reprocessing scheme for innovative molten salt reactor system

“…From fundamental data (redox potentials, activity coefficients [13][14][15]) determined either by experimental measurements or by molecular dynamic simulations, the efficiencies can be calculated for each reaction in its equilibrium state. Such types of calculations and the analytical equations they rely on have already been described [13][14][15][16][17].…”
