摘要:
Natural processes are effective mitigation measures to reduce the spread of radioactive aerosols within the reactor building during severe accidents. Current research on these processes has primarily investigated the deposition efficiency of single-species aerosols. However, the densities of various aerosols produced by fission exhibit significant differences, potentially resulting in varied deposition behaviors. The research revealed that the critical particle diameter for natural aerosol deposition is approximately 1 μm, with notable effects...
