Application of centrifugal filter to aerosol size distribution measurement

Light scattering optical particle counters are widely used for size distribution measurement of aerosol particles. The accuracy of the measured size distribution is dependent upon the response of the counter, which is affected by the refractive index and shape of the particles as well as by the optical design of the instrument, including the light source used. This paper addresses the measurement accuracy of the optical particle counter. Data are presented showing the response characteristics of several widely used commercial optical counters and the comparative size distribution measurement made by means of these instruments.

The general context of the article is related to the development of the laser cutting technique for the fuel debris retrieval on the damaged reactors of Fukushima Dai-ichi. IRSN and CEA are involved in a project, led by ONET, to bring relevant elements to analyze the risk occurred by the dispersion of aerosols emitted by the dismantling operations. Results regarding the aerosols source term characterization emitted during laser cutting of non-radioactive fuel debris simulants were acquired during experiments undertaken on the DELIA cutting laser platform from CEA. IRSN realized aerosol sampling, aerosol size distribution measurement and CFD calculation of aerosol transport and wall deposition. The evaluations performed will enable the Japanese teams responsible for extracting corium from the damaged reactors of Fukushima Dai-ichi to define the best strategies to implement containment, and ultimately to limit the dissemination of radionuclides in the environment.
