Environmental conditions simulating the HCDA on a reduced scale provided the following information: Aerosols resulting from the condensation of gaseous constituents without sodium generally comprise small, spherical particles (diameter 0.01 to 0.25 um) and branched chain-like structures. Aerosols resulting from the condensation of gaseous constituents with sodium generally comprise spherical, small (diameter 0.01 to 0.50 um) particles, with some branched chain-like structures and some agglomerating particles. Electron diffraction analyses identified actinide dioxides, the constituents of stainless steel, an oxide of sodium (Na₂O), sodium uranates (Na₃UO₄ and Na₄UO₅), and a sodium plutonate compound (Na₄PuO₅). Initial solubility studies indicated that 12.1% of the plutonium-239 dissolved in distilled water when a mixed-oxide (Pu, U) stainless steel pellet was vaporized with sodium. Reaction products are controlled kinetically during cooling rather than by equilibrium thermodynamics.
