Simulated environmental conditions modelling the HCDA on a reduced scale have provided the following information: Aerosols resulting from the condensation of gaseous constitutents are generally spherical, small in diameter (0.01 to 0.25 ..mu..m), and branched chain-like structures. Electron diffraction analyses have identified actinide dioxides, the constituents of stainless steel, and various sodium actinates (uranates and zirconates). Some superstoichiometric oxides (UO/sub 2/ /sub 25/ and U/sub 3/O/sub 8/) were noted also. X-ray analyses were not sensitive enough to verify presence of sodium uranates or plutonates. Electron diffraction of the plutonia-doped system should verify these components in this mixed-actinide system. Reaction products are kinetically controlled during cool-down rather than based upon equilibrium thermodynamics.
