Experimental study has been conducted for multiscale characterization of liquid metal (Na) transport within a heat pipe using a neutron imaging technique. Feasibility of nonintrusive imaging of liquid sodium contained inside a nickel alloy heat pipe has been examined for the imaging resolution, exposure time requirements, background noises, and other basic considerations associated with neutron beam scattering. Preliminary results of neutron imaging show fairly acceptable feasibility of neutron imaging of liquid sodium contained inside an alloy jacket. Furthermore, challenges are identified to enhance the spatial and thermal resolutions in order to achieve more physically demanding imaging of the liquid metal thermal transport behaviors.
