Aerosol decontamination performance in filtered venting systems

During a severe nuclear power plant accident, increasing of containment pressure are assumed to be possible. When the containment is damaged by excess pressure or temperature, radioactive materials are released from the containment. A filtered containment venting system (FCVS) reduces containment pressure and the radioactive release into the environment. The FCVS removes radioactive materials via various process. In the pool scrubbing process, flow dynamics (inertial impact, submergence, bubble diameter) and chemical conditions (pH, solubility) affect the removal performance of the radioactive materials. This study has forced on the aerosol removal effect by an inertial impact. (author)
