Abstract Scope |
Actinide-molten salts are used in next-generation nuclear power plants (molten salt reactors/MSRs), since liquid material is inherently resistant to radiation damage, as well as during metal purification. Experimental data on physical properties is sparse, inaccurate, and rarely includes actinides, especially plutonium. LANL offers the infrastructure and expertise to make and handle samples, including Pu, the modeling expertise for actinide salts as well as neutrons at LANSCE to enable characterization. Here, we report evolution of the crystal structures of NaCl, UCl3, and NaCl- 0.352 UCl3 (eutectic) obtained from in situ high temperature neutron diffraction measurements and compare e.g. lattice parameter changes to density functional theory predictions, thus benchmarking such models against experimental data, as well as providing insight on interactions between the two phases in the eutectic composition. |
