Numerical study on cut-off diameter of aerosol particle for filtered containment venting system in nuclear power plant

Abstract This paper presents analytical investigations of the cut-off diameter of aerosol particle for filtered containment venting system in a nuclear power plant. These analyses were done for operation conditions of the containment venting and the numerical results reveal that the particle sizes of fission products released to environment range between 10−8 m and 10−5 m and mostly distribute between 10−7 m and 10−6 m. For designing a filtered containment venting system, the collection efficiency of the filter must be high-quality in the main range 10−7 m – 10−6 m. In this research, the numerical results can offer nuclear power plant a useful reference to design and set up FCVS.
