摘要: 

High-power laser application is considered as a promising solution forefficiently cutting structural components and cleaning contaminatedsurfaces in thenuclear reactor decommissioning.However, a significant proportion of submicron radioactive aerosol particles could generate, typically for those within 0.1 to 1 μm, which are challenging to remove using traditional containment water spraysand posing significant environmental and health risks. To address this challenge and optimize radioactive aerosol control, experimental studies at the UTARTS facility of the University of Tokyo focused on laser-generated aerosol characterization and innovative methods for efficient aerosol management. A novel agglomeration technique involving pre-injected charged water mist was proposed and validated under various experimental conditions, demonstrating improved aerosol scavenging performance. Besides, an electrical charging system for water spray was developed and improved through electrode configuration adjustments to accelerate aerosol removal. In this presentation, insights and outcomes from recent UTARTS experimental studies to develop practical and effective strategies for managing laser-generated radioactive aerosols are introduced. The findings contribute valuable knowledge for future development of safe and sustainable nuclear reactor decommissioning strategies.
