Abstract
When accidents happen in a nuclear power plant, especially the leakage of radioactive materials, the radioactive aerosol, especially the submicron particle is likely to spill while crossing through the cracks of the pressure vessel or the containment, which brings serious harm to the working staff, to the environment and to the surrounding residents. This study attempts to calculate the thermophoretic deposition efficiency of submicron particle in the temperature field of the cracks and analyze the variation of deposition efficiency by selecting the appropriate geometric models and mathematical models. Pointing out the differences of submicron particle from micron particles in the size, flow and so on. And then the effective means by which the submicron particle can be inhibited in nuclear power plant accidents will be found, providing better protection for the safety of nuclear power plants.
