Laser de-icing system improves nuclear plant safety maintenance
A new laser-based de-icing system developed by University of South Florida engineers helps nuclear plants safely and efficiently maintain critical ice condensers.
University of South Florida engineers have developed a laser de-icing system that helps nuclear power plants maintain ice condensers more safely and efficiently. The system, created by Professor Ahmad Vaselbehagh and postdoctoral researcher Ty Hagan, was successfully tested at two Tennessee Valley Authority (TVA) plants. The technology addresses a long-standing issue where ice baskets used for cooling and depressurization can freeze together, making individual inspection difficult.
The laser system is designed to operate in narrow, freezing spaces more than 40 feet below the surface. It precisely cuts through ice without fully melting it, reducing the risk of excess meltwater and refreezing. The system was engineered to meet strict safety and operational requirements for use in nuclear facilities, including radiation and laser safety certifications.
The project involved expertise in mechanical, electrical, and optical engineering, as well as manufacturing and safety compliance. The team also developed training materials and operating procedures to ensure plant personnel can use the system independently. The device can clear several feet of ice in minutes, significantly reducing maintenance time and improving the efficiency of safety inspections.
This innovation demonstrates how advanced laser technology can solve complex maintenance challenges in high-stakes environments. By enabling safer and faster ice condenser maintenance, the system supports the reliability and safety of nuclear power plants, aligning with broader efforts to enhance infrastructure resilience and operational efficiency in critical industries.
