Electrochemical experiments were carried out at 723-823 K to estimate separation coefficients in LiCl-KCl eutectic melt containing uranium and lanthanum trichlorides. Uranium and lanthanum separation coefficients is calcurated with the voltammetric peak potentials of U (III) and La (III), their concentration in the melt and kinetic parameters for U(III) discharge such as diffusion coefficients, and standard rate constants of charge transfer. The diffusion coefficients of U (III) were determined by some electrochemical measurements. The standard rate constants of charge transfer for electroreduction of uranium U(III) +3e
=U were calculated by impedance spectroscopy method.

Total neutron cross sections for La and Pr in the energy range from 20 to 240 keV were measured by using monochromatic neutrons, which were produced by the 
Li(p,n)Be reaction. Theenergy spreads of incident neu- trons were about 18 keV for La and about 8 keV for Pr. The measured total neutron cross sections, with statistical error of 2 - 5% for La and 2 - 3% for Pr, were compared with other available data. The average total neutron cross-section data for both nuclides were interpreted in terms of a spherical optical-model potential. S-wave strength functions S
for La and Pr were deduced from the optical-model parameters obtained by fitting to the average total neutron cross-section data; i.e. S = 0.46
