Measuring Monodisperse Aerosol Transmission in the Los Alamos Respirable Release Fraction Measurement Chamber
- Los Alamos National Lab. (LANL), Los Alamos, NM (United States)
The transmission ratio of monodisperse aerosol (between 1 and 20 μm aerodynamic equivalent diameter) was measured in a modified configuration of the Los Alamos RRFMC (Respirable Release Fraction Measurement Chamber). The RRFMC is a newly built, 20- foot tall, airtight chamber for the drop testing of nuclear material storage containers. The RRFMC was integrated into an existing HEPA filtered wind tunnel system, and is capable of direct measurement of Airborne Release Fraction (ARF) and Respirable Release Fraction (RRF) for plutonium and uranium under various accident conditions. Cerium oxide powder is used as a surrogate for plutonium oxide. Real-time aerosol measurements for aerodynamic diameters from 0.5 to 20 μm are performed with a TSI Inc (Shoreview, MN) Model 3321 APS (Aerodynamic Particle Sizer) spectrometer.
