Abstract

Abstract

In Lead-Bismuth Fast Reactors, the primary coolant liquid lead-bismuth eutectic (LBE) is subject to neutron irradiation, which generates the radioactive nuclide polonium (²¹⁰Po). Given the volatility of ²¹⁰Po, it is essential to thoroughly investigate its migration and diffusion behavior. Aerosols are the primary carriers of volatile radioactive nuclides. Drawing on domestic and international experience in the design and operation of reactor aerosol experimental platforms, this paper presents the development of an LBE aerosol kinetics experimental platform. By combining scanning electrical mobility and optical scattering methods, a broad-spectrum measurement of LBE aerosol particle count and size distribution was achieved. The results indicate that the particle size distribution of LBE aerosols is mainly at the nano-level. Preliminary LBE aerosol kinetics analysis was conducted through data processing of the measurement results, thereby providing key parameters for subsequent safety analysis of radioactive aerosols in Lead-Bismuth Fast Reactors.
