Deposition behavior of PbTe doped LBE aerosol and Te valence prediction: Platform test and First-principles calculation.

In fast reactor investigation with lead-bismuth eutectic(LBE) coolant, understanding the source term within the reactor and its environmental migration is crucial for managing radiation hazards from Po aerosols. The numerical simulations using empirical parameters have proffered insights into the theoretical migration and settling rates of Po aerosols. However, the scarcity of platform tests has impeded the acquisition of particle size distributions and settling velocity, thus weakening the mutual confirmation between experimental and theoretical validation.
