An understanding of fission product behavior during a severe core damage accident in a light water reactor is required to accurately predict the resultant radiological source term to the environment. An internationally sponsored series of four severe fuel damage (SFD) experiments was conducted in the Power Burst Facility (PBF) at the Idaho National Engineering Laboratory to characterize fission product release and transport from severely damaged nuclear fuel. The last experiment, SFD 1-4, was designed to study the behavior of fission products and aerosols generated from control rod, fuel rod cladding, and core structural materials. An on-line aerosol monitor was developed and installed in the test effluent line to study the time-dependent aerosol transport behavior during the experiment. The aerosol monitor consisted of two turbidity meters, used in series, to measure the attenuation of light caused by aerosols in the effluent stream. The outputs from these two attenuation cells were then used to determine the aerosol number density. The high-pressure, high-temperature, and high-radiation field environment of Test SFD 1-4 represented a unique and challenging application for this type of transducer and necessitated considerable development and testing. This paper describes the design and calibration of the aerosol monitor and discusses how the aerosol measurement results were used to aid in the interpretation of Test SFD 1-4.
