CX-270115: Experimental Verification of Post-Accident iPWR Aerosol Behavior – Electric Power Research Institute, Inc.

EPRI proposes to perform a series of experiments to quantify the most influential decontamination factors and their effect on a class of integrated Pressurized Water Reactor (iPWR) containment designs. The experimental design and method includes development of a thermal hydraulic test loop with an integral reactor and containment vessel scaled with similitude to iPWR critical dimensional ratios such as surface area to volume. The experiments will include transient and steady-state measurements of simulants suspended in steam to determine the nature of their removal from the steam due to natural phenomena which include diffusiophoresis, thermophoresis and hygroscopic effects.
